According to people in Binh Phuoc province, the yield of cashew nuts is gradually decreasing due to the influence of the way of caring. The decrease in cashew yield is often due to many reasons, in which, the farming process plays a key role. A lack of attention, nutritional supplementation, watering and a combination of pest and disease factors has led to a decline in cashew production. Therefore, models of intensive farming and transfer of technical advances should be introduced such as pruning, canopy creation, fertilization and pest control. For old gardens, it is necessary to have a new planting solution, to rejuvenate the cashew garden, to help the garden grow, develop well and improve productivity than before.
According to many studies, Vietnam’s cashew yield is higher than the world average but still far below its potential. To explain this, many scientists believe that cashew is an easy plant, adapts well to many lands and does not require care. This leads to thinking and habits of not taking care, mainly to grow by themselves, leading to low productivity. Therefore, experts recommend that you need a specific care regimen and provide enough nutrients for cashew trees to grow. new health, good disease resistance and high yield, large seeds and good quality.
