Ibiremo said that Nigeria produces 960,000 metric tons per year and that the average yield per hectare is 450 to 500 kg of raw cashew nuts. Cashew is cultivated in more than 27 states of Nigeria and has a high potential to increase production beyond any of the competitors, such as cocoa and palm. The cashew tree has the capacity to adapt to variable weather conditions that are marginal for many other tree crops. The average yield of raw cashew nuts is about 15 kg per tree.
The yield of raw cashew nuts per hectare is approximately 1.5 tons per hectare. Cashew nuts are considered to contain carbohydrates, fiber, proteins, calcium, magnesium, phosphorus, potassium, sodium, zinc, vitamin B %26 C and small amounts of folic acid and DFE fat. The Dr. Akin Olonihuwa, former rector of the Kabba College of Agriculture in Kogi State, while explaining the requirements and techniques of modern cashew cultivation, said that the basic requirements include well-drained land; high-quality seeds or seedlings; committed and experienced workers; equipment of tractors, trucks or trailers.
Ibiremo added that the low yield of cashew nuts is due to several factors, namely, the seeds of open-pollinated nuts by farmers with a poor genetic composition, the low use of clones as planting material, the high population density of cashew nuts, poor management of pests and diseases and the reduced attention to soil management problems. In total, there are 33 different types of cashew nuts (types of cashew nuts), but only 26 are available for people to buy. If cashew is cultivated as an organic plant, nutrients are supplied in the form of oil cakes, green leaf compost, vermicompost, poultry manure, etc. The cultivation of cashew nuts was initially practiced to control soil erosion, but later became an important commodity for international trade.
Fertigation, that is, the use of soluble fertilizers through drip irrigation, also increases the economy of cashew nut production in the ultra-high density system. . Clay soils, soils with a pH greater than 8 and soils with poor drainage facilities are not suitable for cashew plants. Good agricultural practices (GAP), which involve choosing good planting materials with appropriate production techniques and proper management after harvest, will result in high-quality, exportable cashew nuts, Ibiremo advised.
The cashew cultivation project report highlights the details of the plant, its importance, the scope of development, its varieties, cultivation methods and requirements, the analysis of costs and benefits and, finally, the support provided by organizations to undertake the cultivation of cashew nuts. Cashew plantations can have three different planting arrangements, such as square, triangular, or rectangular. Currently, there are many different types of cashew seeds planted in Vietnam, but most are 5 main varieties. To combat stem and root borers, which eat the roots and stem of cashew nuts, the Indian cashew research station says: “Clean the trunk of the tree with 3.0% neem oil during the months of June to July and from December to January.
Cashew nuts are packaged according to the Vita Pack method, which involves extracting air from the packaging can, pumping CO₂ and sealing the package. .
