pecan nut yield per tree south africa

If mechanical hedge pruning is part of the long-range plan, it is necessary to consider the process of hedging in the orchard design. This delay in cash flow has led several growers to experiment with planting intercrops between trees during the establishment years. Trees locations marked by circles. The size of the Pecan Nuts is also dramatically better. Fertilization of newly planted trees starts shortly after budbreak at 0.25 to 0.5 lb/tree of 13-13-13. In areas where there is a zinc shortage, young, growing pecan trees must receive foliar zinc applications at approximately 2 week intervals, while the leaves and shoots are still expanding.An effective treatment is Zinc sulfate (36% Zn) at 2 lb/100 gal of water applied to the foliage. However, intercropping should NEVER compromise the pecan trees. Yields generally decreased as clay content increased above approximately 15%, and as sand content decreased below 60%. This area also tends to produce bigger nuts, which result in higher prices. A decade is a long time to wait for a crop to return a profit. It is not recommended to cultivate pecans without irrigation. Roux saw the potential of producing quality nuts with minimal intervention and so, in 1978, planted 5 000 trees on 50ha. The crop can handle frost, as the cold ensures the tree goes into complete dormancy, which ensures even growth in spring. The optimal chemical conditions in the soil for pecan nut production are as follows. On South African shelves, pecan nuts are of the most expensive nuts, despite growing local production. Lack of care during the early years of tree growth can significantly stunt the entire tree planting, delaying on onset of commercial nut production. It seems to take about ten years regardless of the way the orchard was established—direct seeded, transplanted seedlings, or transplanted grafted trees. After all the trees were planted, a bluegrass/ perennial rye alley were established within the double row to allow access to the trees. This increase equates to a 50% improvement in sale price. Hay crops have also been used including several clover/grass mixes. Pecan nuts in South Africa. On the other hand, a rectangle pattern with 12.2 m (40 ft) between N-S oriented rows and 6.1 m (20 ft) between tree rows would probably allow most hedging equipment to pass only in the N-S direction. The trees in the companion row were also spaced 12m apart but arranged in such a way that no tree within a double row is closer than 9m apart. Pecan production is widespread across South Africa, but orchards are increasingly being established in the drier Northern Cape. The pecan has been introduced to foreign countries such as Israel, South Africa, Brazil, and Australia, as well as states on the Eastern Seaboard. plant enough trees/acre to ensure a commercial harvest by year ten. Use a herbicide if necessary. After planting keep a two meter strip (1m on both sides) free of weeds or the intercrop. There are two common thinning patterns that have been used successfully in densely planted pecan orchards: 1} temporary trees placed in every other planting position in every other row and 2} temporary trees planted as a solid line in every other row. Water requirements pecan nuts per production area, water rights and legal requirements Water requirements of pecan nuts in South Africa Very limited information is available – only two studies were done to date, one in Mbombela and the other in Cullinan. The nuts, bought from local farmers are processed and packed in order to export a value added product. Capital inputs are high, especially if hail netting is required, and, except for certain early bearing crops (papayas, granadilla), income cannot be expected for a number of seasons. This increase equates to a 50% improvement in the sales price. Allow them to dry in a place that is protected from rain. Irrigation is a priority for all pecan orchards where the goal is consistent production of top-quality pecans.If weeds are controlled well, and trees are mulched, it is possible to delay initial irrigation installation within the orchard.Irrigation is necessary to reduce losses and improve the growth of young trees. A for better approach, which is becoming the norm in new orchards, is to plant all rows to a single cultivar. This places the product in the top category, resulting in the farmer being paid R11.50 more per kg, equal to a financial gain to the farmer per tree of around R290, adding up to R29,000 per hectare. Fruit and Nut Production 1 INTRODUCTION Successful production of fruit and nut crops requires careful planning from the outset. Since 2012, as South Africa’s production has increased, US exports to China (incl: Hong Kong & Vietnam) have continued to decline. Based on current South African Pecan Nut Producers Association (SAPPA) estimates, there are approximately 62,500 to 75,000 acres of pecans planted in South Africa. One of the first problems growers face in planning a new orchard/intercrop system is deciding on the spacing for the trees. Pecan trees need 285 days a year for growing, with warm nights. Pecan Trees Yield 25% More Nuts in South Africa ExploGrow™ (SumaGrow) treated trees produced an estimated 5kg to 8kg extra per tree, compared with the untreated trees. During extreme droughts, or in areas that are quite arid, irrigation can make the difference between trees thriving versus death. In pecan nut production tree spacing of 10x10m is considered optimal. According to statistics from the SA Macadamia Growers’ Association (Samac), the average export price for macadamia kernels in 2017 was R224.15/kg. Box 623 HARTSWATER South Africa 8750       Troubleshooting. Row crop farmers often end up spacing their trees 15m by 15m. Pecan trees are valued for their shade and appearance, fire-wood, lumber and nut production. In 2017, South Africa surpassed Mexico to become the second largest supplier of pecans to China with an export volume of 13,330 tons (81% of total production), after the USA with an export volume of 35,000 tons. In pecan nut production tree spacing of 10x10m is considered optimal. Wood chip mulch must be 4 to 6 feet in diameter and approximately 6 inches deep. Fertilise, irrigate etc the pecan tree optimally and if required separately from the intercrop. They can take up to ten years to reach full production, but are able to produce nuts for more than a hundred years. While pecan trees like dry conditions, they also require wet roots, and prefer short, cold winters and long, hot summers. Gariep Pecans, is situated in a developing pecan nut producing area at Jacobsdal in the South-West Free State, a nut producing area already established and rapidly growing within the South African pecan nut growing industry. As with macadamias, there is increasing interest in pecan nuts, a tree crop that is less capital-intensive than others, but establishment of a pecan orchard depends strongly on … Neither do they like prolonged wetness; pecans perform best in well-drained soils. The size of the pecan nuts is also dramatically better.  This places the product in the top category, resulting in the farmer being paid R11.50 more per kg, equal to a financial gain to the farmer per tree of around R290, adding up to R29,000 per hectare. Georgia, which had no pecans a few hundred years ago, has within the last 75 years become the #1 pecan producer in the U.S. Texas production averages about 35 million pounds per year. Optimal orchard design for sunlight 2) Seedlings were used to establish this planting. Research about the water requirements for the Vaalharts and Upington areas have commenced. A double tree row planting plan was developed (Fig. Should the trees be making good growth, the same rate must be applied 2-3 more times at 2-week intervals. Especially in places where farmland is expensive, high and even very high planting density (120-272 trees per ha or 48-109 trees per acre) can be a good choice in pecan orchards-but only if there is a good plan in place to manage tree crowding and self-shading that will inevitably arise in future years in densely planted orchards. All Rights Reserved. During 2002, a new block of pecan trees were established as a Pecan Experiment Field using an intercropping system that may offer a better compromise between trees and crops. In orchard surveys conducted in Arizona, pecan production was greatest in trees growing in sandy loam soils. When intercropping is considered, growing conditions for the intercrop is of secondary importance to that of the pecan tree. The objectives for this design were to: Figure 1: A double row planting plan for pecan orchards. To avoid salt damage that might kill the tree, don’t clump fertilizer near the trunk. The nuts are rich in vitamins, carbohydrates and nut oil. Fertilizer must be applied 18-24 inches from the trunk, in a band 2-3-feet long. To shorten establishment time, the most obvious orchard design tool available to producers is increasing tree density in the orchard. 1). Furthermore, most crops will need water at different times than pecan trees. The moisture requirement for pecan nuts starts at around 50 litres of water per tree per day. If tree thinning is part of the overall future management plan, growers can plant very precocious cultivars (e.g., ‘Cheyenne’ or ‘Shoshoni’) as temporary trees to get the fastest possible payback for those temporary trees. South Africa is still a relatively small producer in the world supply chain but that is quickly changing, with South African being the fastest growing producer in the world, outpacing the US and Mexico, in year over year growth. Depending on the area, pecan nuts usually ripen from April to July. View all posts by SumaGrow.Info, Your email address will not be published. If heavy and/or continuous traffic were operated in this 50cm strips, loosen the soil using a ripper plough fitted with a small wing at the tip. During the second season after planting, remove the intercrop from a strip of 50cm on both sides of the tree in order to leave a 3m clean strip. Pecan trees flourish in South Africa. experiment, about 2/5 of the land area is devoted to trees and the grass alleyway, while 3/5 of the land area can be intercropped. To make the double rows, plant the second row of trees only 7m to the east of each primary row. Your email address will not be published. were used to keep a weed free strip about 1m wide. The pecan orchard will render an economic crop for more than 35 to 50 years and cannot be compromised during the initial stages. Figure 3A: Pecan tree 3 years after establishment and the 1st summer after grafting, Figure 3B: Grafted tree, 2nd summer after grafting. According to Dries, a mature tree can easily consume 600ℓ of water per day at the peak of summer. Staniland of Willowfontein, Pietermaritzburg, probably imported the first grafted trees … Select the interplant crop with the pecan nut tree in mind. Grass crops without legumes are considered not suitable if the fertilisation is according to the requirements of the grass crop. These values assume good cultural practices and optimal climatic conditions. Wide spacing makes intercropping easier but seriously delays the onset for economically viable pecan yields. In 1999 Roux's uncontaminated, preservative-, pesticide- and residue-free pecans became the first EU certified Ecocert pecan nuts from Africa. This could help to offset some of the initial costs. Rather sacrifice the return of the intercrop before sacrificing the pecan tree. The significance for nurseries is that they would be able to sell trees to farmers after 3 years instead of 4 years. loutestsite297219755 Within each of these primary rows, spaces the trees 12m apart. Third year rates are increased to 1 to 2 lb/tree following the same schedule as year two. 1) For maximum sunlight exposure for the trees, the trees were laid out in double rows in a north-south direction. Pecan trees suffering from zinc deficiency exhibit drying of apical shoots, little leaf forming in a cluster (known as rosette), bronzing and mottling of leaves, early defoliation, ultimately resulting in poor longevity of the trees and also affecting nut yields adversely. You can discover details including top producing & exporting countries, real-time market prices, local product varieties, seasonality, production & export volumes, and more. Some of the first plantings of pecan trees in the valley were made by Jurie Meyer (Snr) during the mid 1970`s. Trees must be planted for enough apart to allow the hedging equipment, which are often quite large, to pass in the directions to be pruned-many hedgers in the US require at least 9.1 m (20 fti distance between trees to pass easily. The majority of South Africa’s pecan crop is exported to China. When pecan trees are the only consideration in orchard planning, the recommendation will usually be spacing of 10m by 10m. Select the interplant crop with the pecan nut tree in mind. Mulching trees is important as this aids growing conditions by conserving moisture and aiding in weed control. Foliar application of Zn is essential any time trees  are actively growing.Zinc is not effectively translocated within the tree, and so must be directly applied to new, expanding foliage. The increased yield and price equates to a total increase of 75% value per hectare. Some planting patterns lend themselves well to making hedging passes ‘in two or more different directions (including diagonal directions). To assess the value of a pecan tree, several factors should be considered. 50 ft x 50 ft 17 trees per acre 50 ft x 70 ft 12 trees per acre 70 ft x 70 ft 9 trees per acre 100 ft x 100 ft 4 trees per acre Table 3. Harvesting. As soon as the nut is physiologically ripe, the green husk becomes dry, cracks open and the nut drops out. Often orchards are planted with a single main cultivar that makes up the majority of trees in the block. Inter-cropping may therefore be an alternative, but remember most crops will compete with trees for water and nutrients. This limits their ability to deeply explore the soil for available nutrients. Macadamia nuts are hard to beat when it comes to the most lucrative crop per land area used in South Africa. The pecan harvest in South Africa is opposite the US and Mexico with pecan growers beginning harvest May. Irrigate and do pest control according to the requirements of the pecan tree. Explore detailed information about the global Pecan Nut markets. Adding an intercrop into the mix makes things a little bit more complicated. Figure 3 A&B: Trees grafted in the field of the double row systems. Figure 4 A&B. Pecans are outstanding nut-producing landscape trees. The prices for nuts in the shell was on average R75,58/kg. Pecan trees are most frequently planted at densities ranging from 12 to 48 trees per acre, making it possible to produce over 1,000 pounds per acre per year. ... in the pecan-producing areas in semi-arid and arid south-western United States, most soils are alkaline, with pH levels greater than 7.0. “My trees with ExploGrow (SumaGrow), after just 1 year, are just as high as two-year-old trees without ExploGrow (SumaGrow).”. Any adverse condition during the establishing of an orchard will delay the first economic crop and shorten the productive live of an orchard. If you have several pecan trees, you may choose a few pecans from each tree to use in your test sample. Phone: 27 (0)53 474 0061       In older orchards in the western US pollinated trees are sometimes scattered more or less randomly throughout the orchard, perhaps at a slightly higher density on the up-wind side of the block. Pecan nuts. The double row system in the fourth year after establishment with a spring oats inter crop, The information supplied on this website is used at your own discretion. ExploGrow™ (SumaGrow) treated trees produced an estimated 5kg to 8kg extra per tree, compared with the untreated trees.  This increase equates to around 25% improvement in yield.  With N-P-K- fertilizers reduced to 50% of recommended quantities, the use of ExploGrow™ (SumaGrow) is essentially cost neutral. Macadamia and pecan nuts are the predominant tree nut crops grown in the country. When intercropping is then considered, lanes of 8m during year one, 7m during year 2, 6m during year 3 and 4 and 5m during years 5 and 6 after planting can be considered available for intercropping. Yields on pecan trees differ from region to region, with Mpumalanga achieving the lowest yields of around 1,5t/ha to 2,5t/ha. The drier areas in the Northern Cape achieve around 3t/ha to 5t/ha. Soybean intercrop. Or… Planting a crop on both sides of a tree row makes it nearly impossible to access the trees for critical summertime tasks such as; tree training, grafting, weed control, insect control, and watering. South Africa is the world’s third largest producer accounting for 7% of global production . The farmer, Mr. John Pozyn, achieved, by the use of ExploGrow™, an overall net gain of around R37,000 per hectare. Therefore practises like spacing, irrigation, fertilisation, weed and pest control for the intercrop should not jeopardise the pecan tree. One of the greatest deterrents to establishing a new pecan orchard is the long period of time it takes from tree planting to first commercial nut harvest. We use a gram scale for our yield tests, but you could use a regular kitchen scale. To maximize efficiency of hedging, long tree rows are generally better than short pruning passes (to minimize the amount of time turning around) and there must be sufficient space between the ends of tree rows and fences or other obstructions for the equipment to turn around easily. In South Africa the nuts are mainly collected manually from under the trees. The type of irrigation system and location of irrigation emitters (i.e., sprinkler risers and heads) can place restrictions on hedge pruning in the future, as can the location of earthen borders (e.g., separating flood irrigation checks). At the current rate of planting, production could exceed 220 million pounds by 2026. Video to Promote the State of Mississippi, Mississippi Muscadine Grapes Grow Better With SumaGrow. This result is without taking into account the faster growth rate. Cultivar placement within the orchard is among the most basic of these orchard design elements. There are four main types of irrigation available: All of the above have been proven to be effective, but the preferred type will depend on factors such as production region, water availability, water quality and labor supply. For example, a diamond pattern with 10.7 m (35 ft) between North-South oriented rows and 10.7 m (35 ft) between trees in the row gives 10.7 m of room for the hedger to travel north-south, 8.9 m (29.2 ft) to travel in a straight line in two diagonal directions (NW-SE and NE-SW), but only 5.4 m (17.7 ft) in a straight line in the E-W direction. (Fig. Between each set of double rows, a 15m of intercrop (wheat, oats and soybeans) were established. If heavy and/or continuous traffic were operated loosen the soil as described above. After 11 months, the ExploGrow™ (SumaGrow) treated trees already appear to be one year ahead in its growth cycle compared to the control. Generalized inshell yield values for southeastern pecan orchard. This increase equates to around 25% improvement in yield. Email: visser@mweb.co.za. They are not a particularly drought tolerant species {in Arizona and New Mexico pecans use approximately 42 inches of water per season}. Figure 2: The double row pecan planting systems 2 years after tree establishment. of nuts per tree in the 10th growing season and 100 pounds in the 15th growing season. Repeat the reduction of the width of the intercrop strips and loosening of the vacant soil until the intercrop is considered redundant. First determine the purpose of the specific tree. Many agronomic crops have been used as intercrops between young pecan trees including soybeans, wheat, corn and milo. Second year trees receive 0.5 to 1.0 lb/tree of 13-13-13 shortly before budbreak and this needs to be applied 3 more times at 2-week intervals using the same rate. The greater the pollinizer diversity in the orchard, the lower the risks of low main cultivar yield due to poor pollination-so planting two or three different pollinated cultivars is recommended. Wood chips are one of the best materials for mulching pecan trees and, when applied only once at planting, usually deteriorates by the time production begins. In cool climate pecans may not produce nuts, and may suffer from coral spot. Local nut production continues to grow S outh Africa’s diverse climatic conditions are suited to the production of most nuts, including groundnuts (peanuts) and tree nuts. (Fig. Then the yield of the intercrop should be sacrifice and not the growth and development of the pecan tree. By implication, a nursery producing 100,000 trees is likely to bank approximately R17,500,000 one year faster when using ExploGrow™ (SumaGrow). Along each tree row, herbicides Due to the relative long period between establishing a pecan nut orchard and the first economic crop, intercropping is considered. © 2019 Website by CN Marketing. The usage will decline gradually towards winter. When intercropping is then considered, lanes of 8m during year one, 7m during year 2, 6m during year 3 and 4 and 5m during years 5 and 6 after planting can be considered available for intercropping. In this specific When considering intercropping or not, ensure that the soil is prepared properly before planting. Please refer to our disclaimer, Adderss: P.O. Year of tree age Estimated inshell nut production (lbs/Acre) 1-7 0 At Rietpan Nursery we specialize in the growing of pecan trees. Pecans grow best in warm, humid climates. A tree in full production (10 years old) can use up to 750 litres of water per day during the summer months. Do not deviate from the orchard layout or requirements to establish an economic pecan orchard. The water used for irrigation comes from the Vaalharts Irrigation Scheme – the largest in South Africa – with Hartswater at its centre. Of these, this publication addresses the value of pecan trees for nut production. Weed control combined with mulching will minimize the need for irrigation within the first few years. This approach has the disadvantage of not permitting the grower to manage or harvest the different cultivars separately. During the third season after planting, remove the intercrop from another strip of 50cm on both sides of the tree in order to leave a 4m clean strip. Intercropping has one drawback often not considered when designing a planting plan. Distances are in feet. Required fields are marked *. Mexico and the US are the largest producers. A certain percentage of the nuts… pecan production because of a reduction in the incidence of leaf fungal diseases, primarily pecan scab. Being the nursery which marketed almost 20% of the pecan trees planted in 2016 in South Africa, we have become renowned for the quality of the trees which are supplied to clients year after year. First Pecan Nuts full cycle control test results in South Africa, 29 July 2015 With N-P-K- application reduced to 50% of recommended quantities, the use of ExploGrow™ is essentially cost neutral. The pecan nut originated in the USA and is related to the well-known walnut which is cultivated in temperate regions. The growth of South African tree nut production is expected to continue in the 2019/20 MY, based on the increase in area planted as the industry responds to increasing demand from export markets; new orchards coming into production; and the high returns per hectare of tree nuts relative to other crops. The water requirements of a pecan tree are very high. Compare the analytical results of the soil sample and adjust accordingly. Young pecan trees have a small root system. At this time, the only proven effective options for managing crowding and self-shading are tree thinning (i.e., tree removal), mechanical hedge pruning, or a combination of thinning and hedging. The first pecan-nut trees were imported into South Africa by one Wilkinson, a Natal nurseryman, towards the end of the last century. The double row system that was developed met all of our objectives but sacrifices more land to trees than most traditional intercropping schemes. Ingredients 101: Toasting Nuts Is a Necessary Evil & Here’s Why. If a different, more precocious cultivar is used for the temporary trees, the first pattern makes it more difficult to manage and harvest cultivars separately. The For adequate pollination, pecan orchards need a minimum of two permanent cultivars with opposite pollination pattern and good reciprocal overlap of pollen-shed and pistillate-receptivity. Therefore, during the first year, a complete fertilizer such as 13-13-13 is the best choice. This include proper loosening of the top 500mm (at least) layer of soil and addition of fertilisers to optimise the nutrient status of the soil for pecan trees. But at least 20% of the trees planted should be pollinated cultivar trees and no main cultivar tree should be further than 46 m (150 ft) from a pollinated tree. In Florida, pecan trees can be found in all regions between Pensacola and Miami although many of the pecans grown in the state are not well managed. A mature pecan orchard can yield from 1,200 to 2,000 pounds of nuts per acre. Growers planning to farm between tree rows start thinking about the width of common farm equipment and if it’s possible to get a combine down between the trees rows. Enter your email address to follow this blog and receive notifications of new posts by email. The significance for farmers would be to achieve the 1 ton per hectare at least one year faster than the normal 5 years. From an economic point of view, one of the most important short-term considerations is the number of years that it takes for the orchard to reach first harvest and to reach maximum production. This could help you estimate the percentage of edible pecans in your crop. F.S. provide access to the trees at all times. Nutritional program comes in second, but in arid areas, irrigation and weed control are equally important. Gather nuts as they fall to the ground. In experience at a Pecan Experiment Field, an orchard must grow ten seasons before it produces enough nuts to warrant mechanical harvest. Many considerations that go into designing an orchard will have important short-and long-term consequences for the orchard.
