Impact of Climate Condition on Flowering, Fruiting, Kernel and Nut-yield In Newly Added Potential Growing Areas of Cashewnut in India- A Review

Cashew is now an important Horticulture plant for India and now India is exporting cashew at a good scale. Traditional Indian growing area comprises the parts of Karnataka, Maharashtra, Goa, West Bengal, Odisha, Andhra Pradesh and Tamil Nadu states. However, now new areas are coming up with good potential for cultivation such as Gujarat, Jharkhand, Chhattisgarh, Andaman and Nicobar island, North Earsten Hilly States. Cashew cultivars are recommended based on geographical distribution, climate, soil based on these flowering and fruiting time. Cashew nut yield and kernel weight can be different for different varieties and so on its quality with shelling can vary. Flowering and fruiting is greatly influenced by rain because it starts flowering after monsoon, which is greatly influenced by the onset and offset of Indian monsoon that India varies from state to state as India has north-east monsoon and south-west monsoon. Moreover, soil characteristics across India varies widely. Integrated effect of soil, rainfall and temperature drives the optimum growth of cashew trees, which resulted in the change in yield and quality of cashew nuts. The present review paper addresses many of these drivers and their impact on cashew produce in India.
