Abstract

The present study examined the trend analysis of weather parameters temperature, rainfall and with relation to
castor yield. Long-term weather data of 47 years from 1970-71 to 2017-18 was been collected from IMD and castor yield data was collected from DES, 2018. Mann Kendall nonparametric test for identification of trend indicated that annual as well as seasonal (June-Sept) monsoon rainfall over India showed significant decreasing trend. Annual mean, maximum and minimum temperatures averaged over India showed significant warming trend. There was significant increase in total no of consecutive dry days of more than 5 days. Maximum and minimum temperature and rain fall showed significant positive correlation with yield.
