(Fig. Weed control combined with mulching will minimize the need for irrigation within the first few years. 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. When pecan trees are the only consideration in orchard planning, the recommendation will usually be spacing of 10m by 10m. Fruit and Nut Production 1 INTRODUCTION Successful production of fruit and nut crops requires careful planning from the outset. Select the interplant crop with the pecan nut tree in mind. Should the trees be making good growth, the same rate must be applied 2-3 more times at 2-week intervals. To shorten establishment time, the most obvious orchard design tool available to producers is increasing tree density in the orchard. A mature pecan orchard can yield from 1,200 to 2,000 pounds of nuts per acre. Box 623 HARTSWATER South Africa 8750       The significance for farmers would be to achieve the 1 ton per hectare at least one year faster than the normal 5 years. A decade is a long time to wait for a crop to return a profit. Pecans require adequate moisture. Of these, this publication addresses the value of pecan trees for nut production. Wide spacing makes intercropping easier but seriously delays the onset for economically viable pecan yields. 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. Yields generally decreased as clay content increased above approximately 15%, and as sand content decreased below 60%. provide access to the trees at all times. Mr. Pozyn experienced, by the use of ExploGrow™, an overall net gain of around R37,000 per hectare. Generalized inshell yield values for southeastern pecan orchard. 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. Soybean intercrop. In orchard surveys conducted in Arizona, pecan production was greatest in trees growing in sandy loam soils. Along each tree row, herbicides Nutritional program comes in second, but in arid areas, irrigation and weed control are equally important. The prices for nuts in the shell was on average R75,58/kg. Explore detailed information about the global Pecan Nut markets. Cultivar placement within the orchard is among the most basic of these orchard design elements. Many considerations that go into designing an orchard will have important short-and long-term consequences for the orchard. In pecan nut production tree spacing of 10x10m is considered optimal. Macadamia and pecan nuts are the predominant tree nut crops grown in the country. Therefore, during the first year, a complete fertilizer such as 13-13-13 is the best choice. The nuts are rich in vitamins, carbohydrates and nut oil. Mulching trees is important as this aids growing conditions by conserving moisture and aiding in weed control. 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. Furthermore, most crops will need water at different times than pecan trees. 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. Allow them to dry in a place that is protected from rain. They are not a particularly drought tolerant species {in Arizona and New Mexico pecans use approximately 42 inches of water per season}. Fertilization of newly planted trees starts shortly after budbreak at 0.25 to 0.5 lb/tree of 13-13-13. In 1999 Roux's uncontaminated, preservative-, pesticide- and residue-free pecans became the first EU certified Ecocert pecan nuts from Africa. However, intercropping should NEVER compromise the pecan trees. 2) Seedlings were used to establish this planting. Between each set of double rows, a 15m of intercrop (wheat, oats and soybeans) were established. Select the interplant crop with the pecan nut tree in mind. 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. The moisture requirement for pecan nuts starts at around 50 litres of water per tree per day. Pecan nuts. In this specific Figure 3 A&B: Trees grafted in the field of the double row systems. pecan production because of a reduction in the incidence of leaf fungal diseases, primarily pecan scab. These values assume good cultural practices and optimal climatic conditions. 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. According to Dries, a mature tree can easily consume 600ℓ of water per day at the peak of summer. To assess the value of a pecan tree, several factors should be considered. Fertilise, irrigate etc the pecan tree optimally and if required separately from the intercrop. Pecan trees are valued for their shade and appearance, fire-wood, lumber and nut production. They can take up to ten years to reach full production, but are able to produce nuts for more than a hundred years. The crop can handle frost, as the cold ensures the tree goes into complete dormancy, which ensures even growth in spring. 1) For maximum sunlight exposure for the trees, the trees were laid out in double rows in a north-south direction. 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. Repeat the reduction of the width of the intercrop strips and loosening of the vacant soil until the intercrop is considered redundant. Enter your email address to follow this blog and receive notifications of new posts by email. South Africa is the world’s third largest producer accounting for 7% of global production . Irrigate and do pest control according to the requirements of the pecan tree. In experience at a Pecan Experiment Field, an orchard must grow ten seasons before it produces enough nuts to warrant mechanical harvest. 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. A certain percentage of the nuts… Some planting patterns lend themselves well to making hedging passes ‘in two or more different directions (including diagonal directions). Neither do they like prolonged wetness; pecans perform best in well-drained soils. Yields on pecan trees differ from region to region, with Mpumalanga achieving the lowest yields of around 1,5t/ha to 2,5t/ha. Inter-cropping may therefore be an alternative, but remember most crops will compete with trees for water and nutrients. Year of tree age Estimated inshell nut production (lbs/Acre) 1-7 0 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. Distances are in feet. 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. We use a gram scale for our yield tests, but you could use a regular kitchen scale. 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. 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. Research about the water requirements for the Vaalharts and Upington areas have commenced. Pecans are outstanding nut-producing landscape trees. The size of the Pecan Nuts is also dramatically better. 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. This approach has the disadvantage of not permitting the grower to manage or harvest the different cultivars separately. Some of the first plantings of pecan trees in the valley were made by Jurie Meyer (Snr) during the mid 1970`s. Adding an intercrop into the mix makes things a little bit more complicated. After 11 months, the ExploGrow™ (SumaGrow) treated trees already appear to be one year ahead in its growth cycle compared to the control. The pecan harvest in South Africa is opposite the US and Mexico with pecan growers beginning harvest May. 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. were used to keep a weed free strip about 1m wide. Often orchards are planted with a single main cultivar that makes up the majority of trees in the block. 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. The nuts, bought from local farmers are processed and packed in order to export a value added product. 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. The significance for nurseries is that they would be able to sell trees to farmers after 3 years instead of 4 years. Since 2012, as South Africa’s production has increased, US exports to China (incl: Hong Kong & Vietnam) have continued to decline. This increase equates to a 50% improvement in the sales price. A double tree row planting plan was developed (Fig. 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. loutestsite297219755 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. Staniland of Willowfontein, Pietermaritzburg, probably imported the first grafted trees … 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. Hay crops have also been used including several clover/grass mixes. ... 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. 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. 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. Roux saw the potential of producing quality nuts with minimal intervention and so, in 1978, planted 5 000 trees on 50ha. A for better approach, which is becoming the norm in new orchards, is to plant all rows to a single cultivar. Or… The objectives for this design were to: Figure 1: A double row planting plan for pecan orchards. 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 South Africa the nuts are mainly collected manually from under the trees. The pecan nut originated in the USA and is related to the well-known walnut which is cultivated in temperate regions. Optimal orchard design for sunlight 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. Wood chip mulch must be 4 to 6 feet in diameter and approximately 6 inches deep. This increase equates to around 25% improvement in yield. The first pecan-nut trees were imported into South Africa by one Wilkinson, a Natal nurseryman, towards the end of the last century. Intercropping has one drawback often not considered when designing a planting plan. Lack of care during the early years of tree growth can significantly stunt the entire tree planting, delaying on onset of commercial nut production. After all the trees were planted, a bluegrass/ perennial rye alley were established within the double row to allow access to the trees. of nuts per tree in the 10th growing season and 100 pounds in the 15th growing season. Figure 2: The double row pecan planting systems 2 years after tree establishment. The farmer, Mr. John Pozyn, achieved, by the use of ExploGrow™, an overall net gain of around R37,000 per hectare. 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. 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. 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. Row crop farmers often end up spacing their trees 15m by 15m. This increase equates to a 50% improvement in sale price. 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. The double row system that was developed met all of our objectives but sacrifices more land to trees than most traditional intercropping schemes. 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. 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. The Then the yield of the intercrop should be sacrifice and not the growth and development of the pecan tree. The drier areas in the Northern Cape achieve around 3t/ha to 5t/ha. At the current rate of planting, production could exceed 220 million pounds by 2026. If heavy and/or continuous traffic were operated loosen the soil as described above. Therefore practises like spacing, irrigation, fertilisation, weed and pest control for the intercrop should not jeopardise the pecan tree. 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. 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. This could help to offset some of the initial costs. Grass crops without legumes are considered not suitable if the fertilisation is according to the requirements of the grass crop. In cool climate pecans may not produce nuts, and may suffer from coral spot. The pecan has been introduced to foreign countries such as Israel, South Africa, Brazil, and Australia, as well as states on the Eastern Seaboard. First determine the purpose of the specific tree. Young pecan trees have a small root system. Do not deviate from the orchard layout or requirements to establish an economic pecan orchard. 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. One of the first problems growers face in planning a new orchard/intercrop system is deciding on the spacing for the trees. F.S. To avoid salt damage that might kill the tree, don’t clump fertilizer near the trunk. Due to the relative long period between establishing a pecan nut orchard and the first economic crop, intercropping is considered. The water used for irrigation comes from the Vaalharts Irrigation Scheme – the largest in South Africa – with Hartswater at its centre. Fertilizer must be applied 18-24 inches from the trunk, in a band 2-3-feet long. 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. 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. When intercropping is considered, growing conditions for the intercrop is of secondary importance to that of the pecan tree. This could help you estimate the percentage of edible pecans in your crop. Trees locations marked by circles. On South African shelves, pecan nuts are of the most expensive nuts, despite growing local production. Harvesting. It is not recommended to cultivate pecans without irrigation. Pecan nuts in South Africa. A tree in full production (10 years old) can use up to 750 litres of water per day during the summer months. This delay in cash flow has led several growers to experiment with planting intercrops between trees during the establishment years. The optimal chemical conditions in the soil for pecan nut production are as follows. If you have several pecan trees, you may choose a few pecans from each tree to use in your test sample. View all posts by SumaGrow.Info, Your email address will not be published. When considering intercropping or not, ensure that the soil is prepared properly before planting. Required fields are marked *. 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. Pecans grow best in warm, humid climates. Ingredients 101: Toasting Nuts Is a Necessary Evil & Here’s Why. 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. Rather sacrifice the return of the intercrop before sacrificing the pecan tree. Phone: 27 (0)53 474 0061       Pecan trees flourish in South Africa. The water requirements of a pecan tree are very high. The usage will decline gradually towards winter. 1). 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. Within each of these primary rows, spaces the trees 12m apart. 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. 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. Troubleshooting. As soon as the nut is physiologically ripe, the green husk becomes dry, cracks open and the nut drops out. Video to Promote the State of Mississippi, Mississippi Muscadine Grapes Grow Better With SumaGrow. This area also tends to produce bigger nuts, which result in higher prices. It seems to take about ten years regardless of the way the orchard was established—direct seeded, transplanted seedlings, or transplanted grafted trees. plant enough trees/acre to ensure a commercial harvest by year ten. Figure 4 A&B. Mexico and the US are the largest producers. This result is without taking into account the faster growth rate. Your email address will not be published. Other regions of production include Australia, Brazil, Israel, Mexico, and South Africa. 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. You can discover details including top producing & exporting countries, real-time market prices, local product varieties, seasonality, production & export volumes, and more. The increased yield and price equates to a total increase of 75% value per hectare. 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). To make the double rows, plant the second row of trees only 7m to the east of each primary row. Email: visser@mweb.co.za. 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. Pecan production is widespread across South Africa, but orchards are increasingly being established in the drier Northern Cape. Depending on the area, pecan nuts usually ripen from April to July. 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 … According to statistics from the SA Macadamia Growers’ Association (Samac), the average export price for macadamia kernels in 2017 was R224.15/kg. Any adverse condition during the establishing of an orchard will delay the first economic crop and shorten the productive live of an orchard. Compare the analytical results of the soil sample and adjust accordingly. Gather nuts as they fall to the ground. 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. While pecan trees like dry conditions, they also require wet roots, and prefer short, cold winters and long, hot summers. The pecan orchard will render an economic crop for more than 35 to 50 years and cannot be compromised during the initial stages. 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. All Rights Reserved. Third year rates are increased to 1 to 2 lb/tree following the same schedule as year two. “My trees with ExploGrow (SumaGrow), after just 1 year, are just as high as two-year-old trees without ExploGrow (SumaGrow).”. After planting keep a two meter strip (1m on both sides) free of weeds or the intercrop. In pecan nut production tree spacing of 10x10m is considered optimal. Macadamia nuts are hard to beat when it comes to the most lucrative crop per land area used in South Africa. © 2019 Website by CN Marketing.
