ultra high density mango plantation south africa

Densely packing the fields with trees will allow for a more thorough use of an acre of land, leaving less space available for weeds to grow. Having taken up the UHDP programme three years ago, Naidu planted over 600 trees in an acre, compared with just 40 trees in the traditional practice, which yielded him just 1.5 tonnes of mangoes an acre. The majority of time is spent maintaining the ground cover and weeding around the trees, walking the field, pruning and training branches. Fruit is borne on the ends of branches, so spacing too closely may severely limit fruit production in mature trees d… I started a You tube channel, The Mango Loa Project, and have uploaded 6 videos that go over the ultra high density plantation and the open Tatura trellis system. With the Espalier style a single leader is established that grows up, while a single branch is trained laterally or horizontally along the wire on each side of the leader. For the third and final year, We have a field day coming up in the spring, by then there should be fruits on the trees and with the trellised field we will continue to go over the demands of pruning and training in the first 3 years of planting. Each hole was dug 36 inches deep by 20 inches long by 8 inches wide. In UHDP mango plantation, the no. Ultra high density plantation (UHDP) techniques for mango will be demonstrated by planting 310 trees on a 1/2 acre of land. 5:11. This is in contrast to the 7-8 years taken by traditional methods of cultivation. COGSHALL, 820_26 AN INTEGRATED APPROACH FOR MANGO PRODUCTION AND QUALITY MANAGEMENT, 820_27 STARCH LOCALISATION IN MANGO TREE: HISTOLOGICAL OBSERVATIONS, 820_28 THE EFFECT OF GIRDLING ON FLOWERING AND LEAF NET PHOTOSYNTHESIS IN MANGO CV. There is a lot of interest for high density planting and at the moment my project is the largest trial in the islands. Dhake, S.S. Deshpande, V.R. The main limitation of this project is that it is a three year project and it will not get into the production phase of the orchard. The sub-lateral branches are established with each new flush, every 6 to 10 inches, and this is where most of the flowers and subsequent fruit will develop. However, that time and effort is made up when it comes to harvesting the low trees, which is done from the ground and picked by hand. We need more trials. Block or high density plantings provide natural protection from wind, but avoid planting trees too close together because they will compete with each other for light, water and nutrients. UHDP leads to mango orchards attaining their full potential in 3-4 years. I began by planting all four sides, then I planted a row in the middle to use as site points to try to line up the trees. Because these two orchard management systems are relatively new, there is very little data on production. After planting, mangoes develop a strong taproot that can extend to 6 m deep. However, the cost for the materials needed to make your own grafted trees come up to around $2.80 per tree and the 18 months process it takes to grow and graft the trees. Making a template to follow when auguring the holes is essential to getting the right angle when setting the posts. Stand alone UHDP mango fields in India have reported harvests of 8 tons per acre, over double the global average of 3.5 tons per acre. In traditional farming about 70 trees are planted in one acre of land and the growth of tree is very big. Pruning is required every two months and it is important to keep up with each flush of new leaves and growth. Boards were used to make the holes smaller and to make the concrete block a trapezoid shape, reciprocating saws are great for cutting chain, a template to follow when digging holes and setting posts. Through trials done in India and Australia, we know that mango trees thrive under heavy pruning and aside from lessening the demand on labor, there was also an increase in yield and quality of the fruit, increasing production to 8 to 12 tons per acre, while shortening the time to maximum production from 7 to 10 years to three years. The objective of the Mango Loa project is to improve the production and quality of Hawaii’s mango industry by demonstrating and comparing two new innovative orchard management systems for tropical fruits, these are the ultra high density plantation and the open Tatura trellis system. Pruning the uhdp field requires a little more thought and strategy, because of the importance of branch placement as well as optimal angles for best support. Some of the work can be started in the nursery. Reducing labor costs and the need for expensive special equipment, while increasing production through better practices, will go a long way in improving the sustainability of Hawaii’s farmers. Hawaii is in the process of rebuilding its agricultural industry. Pruning in these two systems is more time consuming and labor intensive, over the first three years, than pruning in the standard mango orchard. Now, Naidu is hopeful that his 14-acre mango farm at Samireddypalli village, 12 km from Chittoor town in Andhra Pradesh, will yield five tonnes of mango per acre this year. Year 1. A series of trials are being carried out to standardize package of practices including evaluation of mango … Ghana: Mango farmers using ultra-high density plantation tech Mango farmers have been taken through ultra-high density plantation (UHDP) technology to improve yields … This year I am opening up my farm to the nonprofit organization GoFarm Hawaii; this group trains aspiring farmers in the classroom and field. Five rows of wire were attached to the posts from the ground up. Field preparation began by hiring a bulldozer to clear the field of brush and grass. A state of the art 140 t/day capacity mango processing plant was established in 1997. Eight grafts were planted in normal density and 216 grafts were planted in high density employing about 0.162 ha area for each density. The work is easy, but it takes time to selectively prune and thin out new growth. Trees are staked up as needed and flowers are removed so the trees can focus on vegetative growth. Open Tatura Trellis System and the benefits. Balsubrahmanyam. The first goal is to set a single trunk at 3 feet. I consulted with one farmer at his farm and helped install one row of trellis. Generally about 60 mango saplings can be planted in one acre of orchard area. wire strainers it make easy to tension the wire. When you factor in the costs for the materials needed to build the trellises plus the costs of the UHDP field, it comes to $12,962 per acre, assuming the farmer is making his or her own trees and not purchasing. I am currently scheduled to be a presenter at both events later this year. Once a row was back filled, 1/2″ black tubing was laid down and covered with three foot wide black ground cover. Orchard maintenance is difficult and labor intensive. the most developed trees in this field are now at this stage. The trees are nearly the desired size and pruning takes three to four minutes per tree, now it takes nearly six hours to prune the whole field. These are a couple of concerns that make tropical fruit farming in Hawaii prohibitive. As the branch grows laterally, the terminal bud is removed, when the branch flushes new growth, there will be 2 to 10 new branches, one branch will be selected to be the primary lateral growing branch, while one or two other shoots are left to form the sub-lateral branches,  all other shoots are removed. CV. the Horizontal Cordon or single leader is the preferred technique for training mango trees, A 3 year old tree on Maui where you can clearly see the leader. My next field day is scheduled for the end of January , where the topics will be UHDP year two and the most important tasks and a demonstration on the open tatura trellis system (OTTS); there is a lot of interest on this topic. Most of the tours were for individual farmers that were from other islands and visiting Kauai; two farmers from Oahu, one farmer from Maui, and two farmers from Hawaii island. Trees are planted 8 feet apart in rows while being trained up the trellis. Once this year’s field is planted I will have the data needed to do a detailed cost analysis of the UHDP vs. open tatura trellis system vs. traditional orchard layout. Here is where it is very important to keep up with every flush of new growth. B. Krishna, A.N. India’s main export destinations for mango are the USA and other Middle East countries with a limited quantity being shipped to the European market. Irrigation in Mango Farming Fruits are medium sized having strong and pleasant flavour. 2019-38640-29881 with the University of Maryland to develop and disseminate information about sustainable agriculture. Year two, the main focus was developing the canopy of the tree by constantly pruning and tipping, this encourages branching and spreading out. Year one  began by starting 600 seedlings of “common” mango. I did an interview for KKCR Kauai community radio, talking about the mango loa project and the advantages of high density fruit farming. Benefits of Ultra High Density Plantation in mango. 5 years ago | 1.8K views. Pruning, while labor intensive, require nothing more than clippers and a hand saw. I will attend the Waipa Mango Festival and the Hawaii tropical fruit growers conference, where I will continue to promote the project. There is a good number of Hawaii farmers following along with a lot of interest. A wire basket was made with concrete mesh and a 12 inch piece of 5/8 inch rebar with 5/8 inch by four feet long chain attached and placed within the basket to add strength to the concrete. This year’s Hawaii Tropical Fruit Growers state conference’s main theme was high density and trellising tropical fruits. Fresh mangoes and mango pulp are important items of agro-exports from India. This project was focused on mangoes, but here in Hawaii we can grow all tropical fruits and these two systems have increased the production with other fruits. Hawaii is the host to a number of destructive insects and the fruit flies may cause the most damage. The otts field uses a lot of trellis clips and vinyl tape for training the trees along the trellis, which is another costs that adds up when dealing with 600 trees per acre. The materials for the trellis cost about $13,000 per acre, which can be very cost prohibitive, especially when considering planting 10 acres or more. The open Tatura trellis system is demonstrated on a 1/2 acre of land by planting 300 mango trees on five rows of trellis. CV. responsibility over the next year is to train and prune the trees to get the desired shape. Through the group, I have also been able to reach people all over the world. A total of 10 acres was planted using this innovative cultivation technique promoted by Jain irrigation. Also the low trees will allow for easier protection of the fruit from bird, bug, and critter damage; bagging the fruit or installing bird netting can be better accomplished. Playing next. High Tensile 12 1/2 Gauge 170,000 psi Steel Wire. CV. Ultra High Density Plantation (UHDP) Versus Open Tatura Trellis System (OTTS). 2″ x 4″ x 8′ cross pieces were added to the top of the posts for stabilization. Quick Note: You can buy Alphonso Mango plant from here. The first year of pruning and training was focused on developing the main trunk and the scaffold branches that provide the main structure and support of the tree. A power point presentation is in the works and will be a guide to UHDP techniques and OTTS, a how to presentation that will be made at this year’s annual garden fair and mango Festival. The results are discussed in detail. As the scaffold branches are forming it is important to choose branches that are evenly spaced at a 45 degree angle. With the field prepped and laid out, it is time to start planting. All work is done from the ground, everything is done with simple hand tools, and in India they say that one person can manage up to 10 acres by his or herself. Mango can be grown in a wide range of soils except clayey or extremely sandy or rocky calcareous, alkaline or water logged soils. Ultra High Density Plantation in Mango. The Tatura trellis system has been around for about 30 years and was developed at the Tatura research institute in Victoria, Australia, with the goal of improving productivity and sustainability of temperate zoned fruits and through trial and error the trellises were a success and the practice has been accepted worldwide. AgricultureDotPk. Mango farmers of south Gujarat have started adopting new agricultural technology to cultivate high density mango orchards in the region. I have been in contact with people from Florida and Arizona, India, Thailand, and Australia about my project and the movement towards ultra high density. Sustainable Agriculture Research and Education. COGSHALL, 820_29 UNRAVELLING THE MECHANISM OF MANGO FLOWERING, 820_30 MODELLING THE EFFECTS OF FLOWERING, DROUGHT AND FRUIT LOAD ON MANGO LEAF PHOTOSYNTHESIS, 820_31 MORPHO-HISTOLOGY OF 'MANILA' AND 'HADEN' FRUIT DEVELOPMENT. The mango tree is a sub-tropical evergreen tree that is widely dispersed throughout the tropics. the first lateral branches are tied down on the first wire, the leader is on the second wire, trellis clips and vinyl tape are used to attach the branches to the wire, the graft point is too high and the branch cannot be tied to the first wire, leaving the tip of the lateral branch untied and upward facing is important for proper growth. An intercrop distance of 8 meters is maintained as the saplings need space to grow and become trees. Try this to achieve high yield with low land and great quality mangoes with proper pruning every year. The results of some of these trials have shown that mango can be profitably grown under Jalgaon conditions with improved agricultural practices and the puree and concentrate produced by aseptic processing is of world class quality. This will set you back about two months of growing time and if you don’t prune back two sections, the tree will get too tall. At the end of year one, the trees were 4 to 6 feet tall, the main trunk and scaffold branches are developed and the canopy of the tree is beginning to fill in. It is the sub-lateral branches that are pruned back each year to maintain the tree with in its space. But this year I am planting Mango orchard using Ultra High Density Mango Plantation (UHDP). Current trend where you have sufficient water facility is to go for ultra density mango plantation. Planting densities over 300 trees per acre is considered ultra high density. The open tatura trellis system is a “V” style trellis with a 20 inch “open” gap between posts, this is an adaptation from the original design, and it allows the farmer to walk in between the rows. This is substantially more time than the uhdp field, where most of the time difference is from tying down branches to the wire. The standard mango orchard takes seven to ten for the trees to reach maximum production. The next step was to back fill the holes adding a half pound of 16-16-16 and half pound of neem cake to each hole. A series of trials are being carried out to standardize package of practices including evaluation of mango cultivars for yield potential and processing attributes, optimum spacing, irrigation, using drip system, fertigation, crop regulation by pruning, optimum conditions for ripening, organic farming, processing of Alphonso and Totapuri mangoes into puree etc. Under UHDP, Mango is planted at 3×2 m which accommodates 674 plants per acre. Where it was first developed is hard to pinpoint, but India, Australia, Israel, South Africa, and China are a few of the countries that utilize this method for mango production. This site is maintained by SARE Outreach for the SARE program and features research projects supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture. Posts were set 24 inches deep, with the tops of the posts being eight feet above the ground. Dept. So ultra high density mango cultivation can be more helpful for the farmers. When the leader reaches the next wire, it is topped, and with the new growth, a new leader is established and again branches are trained to grow laterally on each side of the leader, all other branches are removed. I am currently half way through planting the field. Another method of pruning utilizes a tractor attachment with rotating blades which allows for mechanical pruning; this method is very fast and efficient, but also very cost prohibitive. I expect there to be more participation at this event because this is the direction that Hawaii’s tropical fruit farmers are heading and Kauai doesn’t have an open tatura demonstration on the island. The soils of the R&D farms are mostly marginal soils – hilly terrain with basaltic ‘murum’ substratum, alkali and saline alkali soils. Improving Hawaii’s mango industry by introducing and comparing two innovative techniques that have increased yields and quality of the fruit while improving on efficiency and management of the orchard. A realistic expectation for mango production is two to five tons per acre, and the Food and Agriculture Organization (FAO) report the global average for mango production at 3.5 tons/acre. If left unpruned, trees will grow between 60 and 100 feet tall in 25 years. 5″ by 10′ posts and 3 1/2″ by 10′ posts were alternated in each row and set 40 feet apart. USDA is an equal opportunity provider and employer. There was 28 participants for this field day, with over half being farmers. Five rows have been laid out, each row has 240 feet of trellis to plant on, with two lines of 1/2 inch poly tubing and 2 gallon/hour drip emitters every 8 feet, one emitter per tree. The largest farms use mechanical lifts to facilitate harvesting, but are very expensive. Hawaii doesn’t have a good resource for grafted trees, wholesale trees from nurseries range from $30 to $50, and with 550 trees per acre that comes out to $16,500 for the trees alone, bringing the installation cost to $22,584. The anchors should be set an equal distance away from the post as it is tall, so my posts are 8 feet tall and the anchors are set 8 feet away from the post.There are many different designs for ground anchors, from large screw shaped rods that are drilled in the ground or a flat steel plate attached to a rod and buried three feet deep. However, thicker stakes could be gathered from the wild for the second year, and by the third year no stakes were required. Pruning in the second year was a lot more intensive, taking 1 to 3 minutes per tree or 6 to 8 hours for the entire field, 4 to 6 times per year. : Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture or SARE. Mango trees are vigorous upward growing trees. Then, in 2011, Tropical cyclone Yasi, a very large cyclone, hit North Queensland again, but this time, the trees that were on trellises survived.

The uhdp field, in the first two years of pruning and training has been fast and easy. Since then, Australia has dedicated a lot towards research and trials to improve and adapt the open Tatura trellis system for tropical fruits. Mango trees grow and produce well on various soil types but a sandy loam or loam (with a clay content of 15 to 25%) is ideal. Ultra high density plantation (UHDP) methods and the open tatura trellis system (OTTS) is the direction that the world’s tropical fruit farming is heading. Two bags of 80 pound Quickcrete was used per hole. The Mango Loa project and the use of ultra high density plantation techniques has the potential to improve the entire tropical fruit industry. The soils of the R&D farms are mostly marginal soils hilly terrain with basaltic murum substratum, alkali and saline alkali soils. This is overlaid with three feet wide black weed mat. A fact sheet was distributed at this event. Seven pairs of treated pine posts were used for each row. This project will cover the first three years, beginning with the installation and following the pruning and training demands leading up to the start of production at three years. Copyright © 2020 International Society for Horticultural Science. Using UHDP methods have had great results for guava, jackfruit, and breadfruit, while the open Tatura trellis system has had excellent results in growing durian, sour sop, litchi, starfruit, and abiu; all excellent fruits that have growing markets. New shoots are thinned down to three and will become the scaffold branches, The end result of the field planting was 10 rows with 31 trees per row. They visit farms to volunteer and get hands on experience, this year my farm will be one of the participating farms. Where it was first developed is hard to pinpoint, but India, Australia, Israel, South Africa, and China are a few of the countries that utilize this method for mango production. The posts are set at a 72 degree angle, which has been determined to be the best angle for optimal light distribution from the bottom of the tree to the top. of tropical plant and soil science/ University of Hawaii Manoa (Other college or university). Traditionally, mango orchards were planted at a density of 50 trees per acre, with a spacing of 25 feet by 25 feet. Tropical fruits is in high demand and Hawaii’s farmers are trying to meet the need.

Densely packing the fields with trees will allow for a more thorough use of an acre of land, leaving less space available for weeds to grow. Having taken up the UHDP programme three years ago, Naidu planted over 600 trees in an acre, compared with just 40 trees in the traditional practice, which yielded him just 1.5 tonnes of mangoes an acre. The majority of time is spent maintaining the ground cover and weeding around the trees, walking the field, pruning and training branches. Fruit is borne on the ends of branches, so spacing too closely may severely limit fruit production in mature trees d… I started a You tube channel, The Mango Loa Project, and have uploaded 6 videos that go over the ultra high density plantation and the open Tatura trellis system. With the Espalier style a single leader is established that grows up, while a single branch is trained laterally or horizontally along the wire on each side of the leader. For the third and final year, We have a field day coming up in the spring, by then there should be fruits on the trees and with the trellised field we will continue to go over the demands of pruning and training in the first 3 years of planting. Each hole was dug 36 inches deep by 20 inches long by 8 inches wide. In UHDP mango plantation, the no. Ultra high density plantation (UHDP) techniques for mango will be demonstrated by planting 310 trees on a 1/2 acre of land. 5:11. This is in contrast to the 7-8 years taken by traditional methods of cultivation. COGSHALL, 820_26 AN INTEGRATED APPROACH FOR MANGO PRODUCTION AND QUALITY MANAGEMENT, 820_27 STARCH LOCALISATION IN MANGO TREE: HISTOLOGICAL OBSERVATIONS, 820_28 THE EFFECT OF GIRDLING ON FLOWERING AND LEAF NET PHOTOSYNTHESIS IN MANGO CV. There is a lot of interest for high density planting and at the moment my project is the largest trial in the islands. Dhake, S.S. Deshpande, V.R. The main limitation of this project is that it is a three year project and it will not get into the production phase of the orchard. The sub-lateral branches are established with each new flush, every 6 to 10 inches, and this is where most of the flowers and subsequent fruit will develop. However, that time and effort is made up when it comes to harvesting the low trees, which is done from the ground and picked by hand. We need more trials. Block or high density plantings provide natural protection from wind, but avoid planting trees too close together because they will compete with each other for light, water and nutrients. UHDP leads to mango orchards attaining their full potential in 3-4 years. I began by planting all four sides, then I planted a row in the middle to use as site points to try to line up the trees. Because these two orchard management systems are relatively new, there is very little data on production. After planting, mangoes develop a strong taproot that can extend to 6 m deep. However, the cost for the materials needed to make your own grafted trees come up to around $2.80 per tree and the 18 months process it takes to grow and graft the trees. Making a template to follow when auguring the holes is essential to getting the right angle when setting the posts. Stand alone UHDP mango fields in India have reported harvests of 8 tons per acre, over double the global average of 3.5 tons per acre. In traditional farming about 70 trees are planted in one acre of land and the growth of tree is very big. Pruning is required every two months and it is important to keep up with each flush of new leaves and growth. Boards were used to make the holes smaller and to make the concrete block a trapezoid shape, reciprocating saws are great for cutting chain, a template to follow when digging holes and setting posts. Through trials done in India and Australia, we know that mango trees thrive under heavy pruning and aside from lessening the demand on labor, there was also an increase in yield and quality of the fruit, increasing production to 8 to 12 tons per acre, while shortening the time to maximum production from 7 to 10 years to three years. The objective of the Mango Loa project is to improve the production and quality of Hawaii’s mango industry by demonstrating and comparing two new innovative orchard management systems for tropical fruits, these are the ultra high density plantation and the open Tatura trellis system. Pruning the uhdp field requires a little more thought and strategy, because of the importance of branch placement as well as optimal angles for best support. Some of the work can be started in the nursery. Reducing labor costs and the need for expensive special equipment, while increasing production through better practices, will go a long way in improving the sustainability of Hawaii’s farmers. Hawaii is in the process of rebuilding its agricultural industry. Pruning in these two systems is more time consuming and labor intensive, over the first three years, than pruning in the standard mango orchard. Now, Naidu is hopeful that his 14-acre mango farm at Samireddypalli village, 12 km from Chittoor town in Andhra Pradesh, will yield five tonnes of mango per acre this year. Year 1. A series of trials are being carried out to standardize package of practices including evaluation of mango … Ghana: Mango farmers using ultra-high density plantation tech Mango farmers have been taken through ultra-high density plantation (UHDP) technology to improve yields … This year I am opening up my farm to the nonprofit organization GoFarm Hawaii; this group trains aspiring farmers in the classroom and field. Five rows of wire were attached to the posts from the ground up. Field preparation began by hiring a bulldozer to clear the field of brush and grass. A state of the art 140 t/day capacity mango processing plant was established in 1997. Eight grafts were planted in normal density and 216 grafts were planted in high density employing about 0.162 ha area for each density. The work is easy, but it takes time to selectively prune and thin out new growth. Trees are staked up as needed and flowers are removed so the trees can focus on vegetative growth. Open Tatura Trellis System and the benefits. Balsubrahmanyam. The first goal is to set a single trunk at 3 feet. I consulted with one farmer at his farm and helped install one row of trellis. Generally about 60 mango saplings can be planted in one acre of orchard area. wire strainers it make easy to tension the wire. When you factor in the costs for the materials needed to build the trellises plus the costs of the UHDP field, it comes to $12,962 per acre, assuming the farmer is making his or her own trees and not purchasing. I am currently scheduled to be a presenter at both events later this year. Once a row was back filled, 1/2″ black tubing was laid down and covered with three foot wide black ground cover. Orchard maintenance is difficult and labor intensive. the most developed trees in this field are now at this stage. The trees are nearly the desired size and pruning takes three to four minutes per tree, now it takes nearly six hours to prune the whole field. These are a couple of concerns that make tropical fruit farming in Hawaii prohibitive. As the branch grows laterally, the terminal bud is removed, when the branch flushes new growth, there will be 2 to 10 new branches, one branch will be selected to be the primary lateral growing branch, while one or two other shoots are left to form the sub-lateral branches,  all other shoots are removed. CV. the Horizontal Cordon or single leader is the preferred technique for training mango trees, A 3 year old tree on Maui where you can clearly see the leader. My next field day is scheduled for the end of January , where the topics will be UHDP year two and the most important tasks and a demonstration on the open tatura trellis system (OTTS); there is a lot of interest on this topic. Most of the tours were for individual farmers that were from other islands and visiting Kauai; two farmers from Oahu, one farmer from Maui, and two farmers from Hawaii island. Trees are planted 8 feet apart in rows while being trained up the trellis. Once this year’s field is planted I will have the data needed to do a detailed cost analysis of the UHDP vs. open tatura trellis system vs. traditional orchard layout. Here is where it is very important to keep up with every flush of new growth. B. Krishna, A.N. India’s main export destinations for mango are the USA and other Middle East countries with a limited quantity being shipped to the European market. Irrigation in Mango Farming Fruits are medium sized having strong and pleasant flavour. 2019-38640-29881 with the University of Maryland to develop and disseminate information about sustainable agriculture. Year two, the main focus was developing the canopy of the tree by constantly pruning and tipping, this encourages branching and spreading out. Year one  began by starting 600 seedlings of “common” mango. I did an interview for KKCR Kauai community radio, talking about the mango loa project and the advantages of high density fruit farming. Benefits of Ultra High Density Plantation in mango. 5 years ago | 1.8K views. Pruning, while labor intensive, require nothing more than clippers and a hand saw. I will attend the Waipa Mango Festival and the Hawaii tropical fruit growers conference, where I will continue to promote the project. There is a good number of Hawaii farmers following along with a lot of interest. A wire basket was made with concrete mesh and a 12 inch piece of 5/8 inch rebar with 5/8 inch by four feet long chain attached and placed within the basket to add strength to the concrete. This year’s Hawaii Tropical Fruit Growers state conference’s main theme was high density and trellising tropical fruits. Fresh mangoes and mango pulp are important items of agro-exports from India. This project was focused on mangoes, but here in Hawaii we can grow all tropical fruits and these two systems have increased the production with other fruits. Hawaii is the host to a number of destructive insects and the fruit flies may cause the most damage. The otts field uses a lot of trellis clips and vinyl tape for training the trees along the trellis, which is another costs that adds up when dealing with 600 trees per acre. The materials for the trellis cost about $13,000 per acre, which can be very cost prohibitive, especially when considering planting 10 acres or more. The open Tatura trellis system is demonstrated on a 1/2 acre of land by planting 300 mango trees on five rows of trellis. CV. responsibility over the next year is to train and prune the trees to get the desired shape. Through the group, I have also been able to reach people all over the world. A total of 10 acres was planted using this innovative cultivation technique promoted by Jain irrigation. Also the low trees will allow for easier protection of the fruit from bird, bug, and critter damage; bagging the fruit or installing bird netting can be better accomplished. Playing next. High Tensile 12 1/2 Gauge 170,000 psi Steel Wire. CV. Ultra High Density Plantation (UHDP) Versus Open Tatura Trellis System (OTTS). 2″ x 4″ x 8′ cross pieces were added to the top of the posts for stabilization. Quick Note: You can buy Alphonso Mango plant from here. The first year of pruning and training was focused on developing the main trunk and the scaffold branches that provide the main structure and support of the tree. A power point presentation is in the works and will be a guide to UHDP techniques and OTTS, a how to presentation that will be made at this year’s annual garden fair and mango Festival. The results are discussed in detail. As the scaffold branches are forming it is important to choose branches that are evenly spaced at a 45 degree angle. With the field prepped and laid out, it is time to start planting. All work is done from the ground, everything is done with simple hand tools, and in India they say that one person can manage up to 10 acres by his or herself. Mango can be grown in a wide range of soils except clayey or extremely sandy or rocky calcareous, alkaline or water logged soils. Ultra High Density Plantation in Mango. The Tatura trellis system has been around for about 30 years and was developed at the Tatura research institute in Victoria, Australia, with the goal of improving productivity and sustainability of temperate zoned fruits and through trial and error the trellises were a success and the practice has been accepted worldwide. AgricultureDotPk. Mango farmers of south Gujarat have started adopting new agricultural technology to cultivate high density mango orchards in the region. I have been in contact with people from Florida and Arizona, India, Thailand, and Australia about my project and the movement towards ultra high density. Sustainable Agriculture Research and Education. COGSHALL, 820_29 UNRAVELLING THE MECHANISM OF MANGO FLOWERING, 820_30 MODELLING THE EFFECTS OF FLOWERING, DROUGHT AND FRUIT LOAD ON MANGO LEAF PHOTOSYNTHESIS, 820_31 MORPHO-HISTOLOGY OF 'MANILA' AND 'HADEN' FRUIT DEVELOPMENT. The mango tree is a sub-tropical evergreen tree that is widely dispersed throughout the tropics. the first lateral branches are tied down on the first wire, the leader is on the second wire, trellis clips and vinyl tape are used to attach the branches to the wire, the graft point is too high and the branch cannot be tied to the first wire, leaving the tip of the lateral branch untied and upward facing is important for proper growth. An intercrop distance of 8 meters is maintained as the saplings need space to grow and become trees. Try this to achieve high yield with low land and great quality mangoes with proper pruning every year. The results of some of these trials have shown that mango can be profitably grown under Jalgaon conditions with improved agricultural practices and the puree and concentrate produced by aseptic processing is of world class quality. This will set you back about two months of growing time and if you don’t prune back two sections, the tree will get too tall. At the end of year one, the trees were 4 to 6 feet tall, the main trunk and scaffold branches are developed and the canopy of the tree is beginning to fill in. It is the sub-lateral branches that are pruned back each year to maintain the tree with in its space. But this year I am planting Mango orchard using Ultra High Density Mango Plantation (UHDP). Current trend where you have sufficient water facility is to go for ultra density mango plantation. Planting densities over 300 trees per acre is considered ultra high density. The open tatura trellis system is a “V” style trellis with a 20 inch “open” gap between posts, this is an adaptation from the original design, and it allows the farmer to walk in between the rows. This is substantially more time than the uhdp field, where most of the time difference is from tying down branches to the wire. The standard mango orchard takes seven to ten for the trees to reach maximum production. The next step was to back fill the holes adding a half pound of 16-16-16 and half pound of neem cake to each hole. A series of trials are being carried out to standardize package of practices including evaluation of mango cultivars for yield potential and processing attributes, optimum spacing, irrigation, using drip system, fertigation, crop regulation by pruning, optimum conditions for ripening, organic farming, processing of Alphonso and Totapuri mangoes into puree etc. Under UHDP, Mango is planted at 3×2 m which accommodates 674 plants per acre. Where it was first developed is hard to pinpoint, but India, Australia, Israel, South Africa, and China are a few of the countries that utilize this method for mango production. This site is maintained by SARE Outreach for the SARE program and features research projects supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture. Posts were set 24 inches deep, with the tops of the posts being eight feet above the ground. Dept. So ultra high density mango cultivation can be more helpful for the farmers. When the leader reaches the next wire, it is topped, and with the new growth, a new leader is established and again branches are trained to grow laterally on each side of the leader, all other branches are removed. I am currently half way through planting the field. Another method of pruning utilizes a tractor attachment with rotating blades which allows for mechanical pruning; this method is very fast and efficient, but also very cost prohibitive. I expect there to be more participation at this event because this is the direction that Hawaii’s tropical fruit farmers are heading and Kauai doesn’t have an open tatura demonstration on the island. The soils of the R&D farms are mostly marginal soils – hilly terrain with basaltic ‘murum’ substratum, alkali and saline alkali soils. Improving Hawaii’s mango industry by introducing and comparing two innovative techniques that have increased yields and quality of the fruit while improving on efficiency and management of the orchard. A realistic expectation for mango production is two to five tons per acre, and the Food and Agriculture Organization (FAO) report the global average for mango production at 3.5 tons/acre. If left unpruned, trees will grow between 60 and 100 feet tall in 25 years. 5″ by 10′ posts and 3 1/2″ by 10′ posts were alternated in each row and set 40 feet apart. USDA is an equal opportunity provider and employer. There was 28 participants for this field day, with over half being farmers. Five rows have been laid out, each row has 240 feet of trellis to plant on, with two lines of 1/2 inch poly tubing and 2 gallon/hour drip emitters every 8 feet, one emitter per tree. The largest farms use mechanical lifts to facilitate harvesting, but are very expensive. Hawaii doesn’t have a good resource for grafted trees, wholesale trees from nurseries range from $30 to $50, and with 550 trees per acre that comes out to $16,500 for the trees alone, bringing the installation cost to $22,584. The anchors should be set an equal distance away from the post as it is tall, so my posts are 8 feet tall and the anchors are set 8 feet away from the post.There are many different designs for ground anchors, from large screw shaped rods that are drilled in the ground or a flat steel plate attached to a rod and buried three feet deep. However, thicker stakes could be gathered from the wild for the second year, and by the third year no stakes were required. Pruning in the second year was a lot more intensive, taking 1 to 3 minutes per tree or 6 to 8 hours for the entire field, 4 to 6 times per year. : Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture or SARE. Mango trees are vigorous upward growing trees. Then, in 2011, Tropical cyclone Yasi, a very large cyclone, hit North Queensland again, but this time, the trees that were on trellises survived.

The uhdp field, in the first two years of pruning and training has been fast and easy. Since then, Australia has dedicated a lot towards research and trials to improve and adapt the open Tatura trellis system for tropical fruits. Mango trees grow and produce well on various soil types but a sandy loam or loam (with a clay content of 15 to 25%) is ideal. Ultra high density plantation (UHDP) methods and the open tatura trellis system (OTTS) is the direction that the world’s tropical fruit farming is heading. Two bags of 80 pound Quickcrete was used per hole. The Mango Loa project and the use of ultra high density plantation techniques has the potential to improve the entire tropical fruit industry. The soils of the R&D farms are mostly marginal soils hilly terrain with basaltic murum substratum, alkali and saline alkali soils. This is overlaid with three feet wide black weed mat. A fact sheet was distributed at this event. Seven pairs of treated pine posts were used for each row. This project will cover the first three years, beginning with the installation and following the pruning and training demands leading up to the start of production at three years. Copyright © 2020 International Society for Horticultural Science. Using UHDP methods have had great results for guava, jackfruit, and breadfruit, while the open Tatura trellis system has had excellent results in growing durian, sour sop, litchi, starfruit, and abiu; all excellent fruits that have growing markets. New shoots are thinned down to three and will become the scaffold branches, The end result of the field planting was 10 rows with 31 trees per row. They visit farms to volunteer and get hands on experience, this year my farm will be one of the participating farms. Where it was first developed is hard to pinpoint, but India, Australia, Israel, South Africa, and China are a few of the countries that utilize this method for mango production. The posts are set at a 72 degree angle, which has been determined to be the best angle for optimal light distribution from the bottom of the tree to the top. of tropical plant and soil science/ University of Hawaii Manoa (Other college or university).
