Abstract
A review of soil and climate conditions of different cashew growing states in India in relation to the production potential of cashew reveals that a well distributed rainfall during growth and pre-flowering phase (from September to November) favours a higher yield potential. Brown forest soil or a deep well drained laterite soil with high water holding capacity and rich in organic matter content appears to be an ideal soil type for better growth and higher productivity of cahsew, while the eroded laterites and coastal sands appear to be poor soil types. The yield potential of cashew is very low under saline/alkaline conditions of the soil and soil water. The cyclonic storms along the East Coast resulting in heavy rainfall, floods and waterlogging also seriously affect the productivity of cashew. Augmenting supplemental irrigation facilities in the rain deficit regions coupled with appropriate soil conservation and fertility management practices are essential in raising the cashew productivity.
