Solution(By Examveda Team)

Castor is a species of perennial flowering plant in the spurge family. It requires a hot, dry climate with an annual rainfall of 500 - 800 mm, of which 500 - 600 mm is needed during the first 3 months of crop growth. High temperatures above 41 degree Celsius at a flowering time even for a short period result in the blasting of flowers in Castor.
