Orion Irresistible Pecans: The pecan nut trees that thrive in Sub Saharan Africa

The pecan industry has a rich and stable history, and the future looks even brighter. Since the 1800s it has shown steady growth, but since China entered the market, that steady growth skyrocketed. Over the last decade, more and more farmers started planting pecan trees with the hope that they will get a piece of that success. The industry is still in its adolescent phase and continues to establish itself. Much research must be done for further development. China's interest in pecans acted as the first catalyst to the increased plantings, but the financial opportunity that followed proved to be the most significant stimulus. Farmers who struggled to make a living off traditional row crops turned to permanent crops as a solution to their financial woes. The boom in nut prices in recent years is expected to continue as consumers opt for healthier foods. This convinced more and more farmers to replace their crops with pecan trees. While pecan farming can be a lucrative venture, aspiring growers must begin with a solid foundation. Pecan nut farming is a long-term investment, dependent on the producer making the correct choices early in the business. Choosing the right location, cultivar and land preparation technique are crucial to ensure orchards function optimally from the start, and that the return on investment is maximised. One of the biggest challenges facing potential pecan farmers is the long wait for a return on investment. It takes six to eight years for a tree to
start producing, and around 10 years until a farmer can start turning a profit. Orchards expected to bear fruit for multiple generations require perfect planning. Any shortcuts taken in the beginning could cost the farmer for years to come. Farmers considering nut farming must order trees timeously as plant material is scarce nowadays. Trees are ordered by cultivar and then the nurseries start to propagate them accordingly. While pecan trees like dry conditions, they also require wet roots, and prefer short, cold winters and long, hot summers. Pecan trees need 285 days a year for growing, with warm nights. The trees can handle frost, as the low temperature ensures the tree goes into complete dormancy, which ensures even growth in spring. High-humidity areas are susceptible to scab, therefore farmers in such areas should invest in tolerant varieties. While pecan trees can grow in shallow soil, the soil should be between at least 100 to 150cm deep for commercial production.

Choose your nursery with care
Farmers must source quality trees. Before placing an order, farmers should ask where the nursery gets its rootstock or seed and whether it can guarantee that the variety is pure. Since there has been a shortage of trees, many new nurseries have popped up that are not accredited. South Africa did not lag behind, and many pecan farms and nurseries sprouted all over the country to supply

the industry. Some of these nurseries export their young trees to other Sub Saharan African countries. Orion Irresistible Pecans is one of those. This nursery farm is accredited with all the regulatory bodies, and is located between Wesselsbron and Bothaville in the Free State province of South Africa. They have over 8 000 trees in their orchard and the nursery offers four varieties - Choctaw, Navaho, Sutex and Wichita. They supply bagged trees in different sizes.
Orion Irresistible Pecans’ bagged trees are grown and prepared in the nursery and are ready to be planted. This method holds many benefits: • The replant success rate is higher • The health, quality and variety are already visible • It reaches the production stage faster
Pecan farming is an expensive and long-term investment. If done properly, it could ensure an income for many generations to come. In the US, there are productive orchards over 100 years old.

Stretch water and reduce
costs with Agrico
by Du Preez de Villiers
Adesperate water shortage handicapped Beerseun Farm’s irrigation operations outside Tzaneen in the northern part of South Africa up to a year ago. But it took a dramatic positive turn when they employed the best technology and equipment they could lay their hands on, to get the maximum out of the water at their disposal. Today, they plant sweetcorn, green beans, pumpkins, brinjals, various cultivars of peppers, papayas, guavas, macadamia nuts, citrus and figs. They mainly supply the retail market such as Freshmark, Woolworths and Pick n Pay, and will send their surplus products to the market. For Woolworths and Pick n Pay, they pack on the farm and will even stick on the labels for upcoming specials! Beerseun has been working with Agrico for over 16 years now. Agrico equipment and systems can be seen all over the farm. Rynier Steenekamp, Production Manager, knows how to use every drop of the limited water supply, and Agrico understands and supports him all the way. "We have centre pivot, drip and micro irrigation, but I am in the process of phasing out the microirrigation systems, because the evaporation is too high. The drippers deliver the same volume of water, but place it directly on the ground, next to the plant,” he says. His pivots are ideal to irrigate full surface areas very efficiently and with high uniformity. Care has been taken to choose the most efficient spray packages, with ideal droplet size, low pressure and at the correct height to minimise possible losses. He also runs the pivots at night to eliminate losses due to evaporation, and the drip irrigation during the day. This is done to utilise the boreholes optimally over 24 hours. The farm's borehole capacity is under pressure. The boreholes take a long time to recover if too much water is extracted. Agrico worked with Rynier to devise a plan to make the best use of the limited water without damaging the boreholes or the pumps by running dry. They purchased and installed a very nifty system that shuts down the pump as
