To produce pecan nuts successfully and profitable, it is essential to plant cultivars that comply with the high standards concerning adaptability to an area, disease tolerance, production, kernel percentage, nut size and shape, appearance and taste of the kernels. In Mpumalanga, the average planting density is 7.4 m x 4 m. Many growers are moving to lower density plantings, for instance, 9 m x 5 m. Lower density plantings will still require pruning, and perhaps 8 m x 4 m or 8 m x 4.5 m will provide a good balance between pruning intensity and optimal yield per hectare. The drier areas in the Northern Cape achieve around 3t/ha to 5t/ha. Labourers are, however, required to pick up the nuts the harvester has missed. This means that you can collect 13 tons of shelled walnuts per hectare. Table 3 provides yield projections for an orchard of improved varieties. Once the suitability of the climate for pecan nut production is confirmed, one has to investigate the suitability of the soil and what pre-plant and cultural practises need to be implemented. The cultivars that are mostly being planted currently are; Wichita, Choctaw, and the pollinator, Navaho. 0000004768 00000 n

Parts of South Africa have the world’s best climate for growing pecan nuts (Carya illinoinensis). It was a bold move, as pecan trees begin yielding an economically significant crop only from eight years onwards. In 2018, China's peanut yield amounted to 3,752 kilograms per hectare.

The pecan nut (Carya illinoensis), like the walnut, belongs to the family Juglandaceae. The yield of this crop depends on numbers of key factors such as soil types, climate conditions, the way of irrigation, and cultivar, used for cultivation. Gunter Hollenbach explains. The following table shows the vegetable oil yields of common energy crops associated with biodiesel production. After 10 years, yield no longer increases and remains at the same level. Adam Branson and Alice Gibbons Dan Berman Pecan, Macadamia, Pistachio, Walnut and Almond Situation Tree Nuts Annual Mexico MX1069 It is also important that rows are wide enough to accommodate the machinery used during harvesting â which runs from April to July, depending on the cultivar.
