The first pecan-nut trees were imported into South Africa by one Wilkinson, a Natal nurseryman, towards the end of the last century. 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. Explore detailed information about the global Pecan Nut markets. 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). View all posts by SumaGrow.Info, Your email address will not be published. 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. In orchard surveys conducted in Arizona, pecan production was greatest in trees growing in sandy loam soils. 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. Wide spacing makes intercropping easier but seriously delays the onset for economically viable pecan yields. Pecan nuts in South Africa. A double tree row planting plan was developed (Fig. The pecan has been introduced to foreign countries such as Israel, South Africa, Brazil, and Australia, as well as states on the Eastern Seaboard. 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. 2) Seedlings were used to establish this planting. Pecans are outstanding nut-producing landscape trees. 1) For maximum sunlight exposure for the trees, the trees were laid out in double rows in a north-south direction. 1). 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. Mr. Pozyn experienced, by the use of ExploGrow™, an overall net gain of around R37,000 per hectare. 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. 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. 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. Gather nuts as they fall to the ground. 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. In experience at a Pecan Experiment Field, an orchard must grow ten seasons before it produces enough nuts to warrant mechanical harvest. Please refer to our disclaimer, Adderss: P.O. 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. Roux saw the potential of producing quality nuts with minimal intervention and so, in 1978, planted 5 000 trees on 50ha. Some of the first plantings of pecan trees in the valley were made by Jurie Meyer (Snr) during the mid 1970`s. Yields on pecan trees differ from region to region, with Mpumalanga achieving the lowest yields of around 1,5t/ha to 2,5t/ha. Fertilizer must be applied 18-24 inches from the trunk, in a band 2-3-feet long. 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. plant enough trees/acre to ensure a commercial harvest by year ten. Hay crops have also been used including several clover/grass mixes. While pecan trees like dry conditions, they also require wet roots, and prefer short, cold winters and long, hot summers. The double row system that was developed met all of our objectives but sacrifices more land to trees than most traditional intercropping schemes. 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. Select the interplant crop with the pecan nut tree in mind. On South African shelves, pecan nuts are of the most expensive nuts, despite growing local production. 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. According to statistics from the SA Macadamia Growers’ Association (Samac), the average export price for macadamia kernels in 2017 was R224.15/kg. Along each tree row, herbicides Within each of these primary rows, spaces the trees 12m apart. Pecan production is widespread across South Africa, but orchards are increasingly being established in the drier Northern Cape. 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. Figure 4 A&B. Trees locations marked by circles. The pecan orchard will render an economic crop for more than 35 to 50 years and cannot be compromised during the initial stages. It seems to take about ten years regardless of the way the orchard was established—direct seeded, transplanted seedlings, or transplanted grafted trees. Then the yield of the intercrop should be sacrifice and not the growth and development of the pecan tree. 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. 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. After all the trees were planted, a bluegrass/ perennial rye alley were established within the double row to allow access to the trees. A tree in full production (10 years old) can use up to 750 litres of water per day during the summer months. Many considerations that go into designing an orchard will have important short-and long-term consequences for the orchard. 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. A decade is a long time to wait for a crop to return a profit. The Macadamia nuts are hard to beat when it comes to the most lucrative crop per land area used in South Africa. The farmer, Mr. John Pozyn, achieved, by the use of ExploGrow™, an overall net gain of around R37,000 per hectare. This area also tends to produce bigger nuts, which result in higher prices. Since 2012, as South Africa’s production has increased, US exports to China (incl: Hong Kong & Vietnam) have continued to decline. Yields generally decreased as clay content increased above approximately 15%, and as sand content decreased below 60%. Enter your email address to follow this blog and receive notifications of new posts by email. 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. F.S. 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. They are not a particularly drought tolerant species {in Arizona and New Mexico pecans use approximately 42 inches of water per season}. This increase equates to a 50% improvement in the sales price. During extreme droughts, or in areas that are quite arid, irrigation can make the difference between trees thriving versus death. Video to Promote the State of Mississippi, Mississippi Muscadine Grapes Grow Better With SumaGrow. 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. Lack of care during the early years of tree growth can significantly stunt the entire tree planting, delaying on onset of commercial nut production. The pecan nut originated in the USA and is related to the well-known walnut which is cultivated in temperate regions. Soybean intercrop. If you have several pecan trees, you may choose a few pecans from each tree to use in your test sample. Between each set of double rows, a 15m of intercrop (wheat, oats and soybeans) were established. of nuts per tree in the 10th growing season and 100 pounds in the 15th growing season. Or… 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. One of the first problems growers face in planning a new orchard/intercrop system is deciding on the spacing for the trees. A mature pecan orchard can yield from 1,200 to 2,000 pounds of nuts per acre. At Rietpan Nursery we specialize in the growing of pecan trees. This increase equates to around 25% improvement in yield. The prices for nuts in the shell was on average R75,58/kg. Young pecan trees have a small root system. Mulching trees is important as this aids growing conditions by conserving moisture and aiding in weed control. We use a gram scale for our yield tests, but you could use a regular kitchen scale. Repeat the reduction of the width of the intercrop strips and loosening of the vacant soil until the intercrop is considered redundant. They can take up to ten years to reach full production, but are able to produce nuts for more than a hundred years. 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. A for better approach, which is becoming the norm in new orchards, is to plant all rows to a single cultivar. 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. A certain percentage of the nuts… 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. To avoid salt damage that might kill the tree, don’t clump fertilizer near the trunk. Pecan trees flourish in South Africa. 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.
