Climatic Requirement

Climatic Requirement 

Chilli prefers a warm humid climate during early stages and a dry weather towards the maturity of pods. It is grown in both tropical and subtropical areas up to 2,000 m above mean sea level. As a rainfed crop, it is grown in areas receiving an annual rainfall of 75-100cm. Excessive or heavy rainfall during its growth causes defoliation and rotting. In north India, chilli is grown in kharif and summer seasons as the crop does not withstand the low temperature in winter. But in south India, due to the mild winter chilli is grown in all the 3 seasons. June-October is the major chilli- growing period in south India. The dry chilli is mainly grown as a rainfed crop. During the growing period which extends over 4 months, maximum temperature ranging from 20O-30OC and a minimum temperature not below 10OC is ideal. High temperature during summer accelerates flower and fruit drop causing poor fruit set. The rain during November results in the incidence of powdery mildew which causes heavy defoliation. The fruit color is affected at temperatures below 15OC. Low moisture during flowering also causes a heavy reduction in yield during summer. During rainy season, wilting and blight are the serious problems of chili in Sikkim.
