Previous Year Question

In groundnut, Gypsum (Calcium Sulphate) is particularly important because it supplies Calcium and Sulphur to the crop. Calcium, in particular, plays an important role in pod formation and kernel development.

After fertilization in groundnut, the developing peg enters the soil and the pod develops there. Therefore, adequate availability of Calcium in the pod zone is important for proper pod formation and filling.

Agricultural recommendations commonly advise the application of gypsum to the soil around the flowering/pegging stage. Its application helps in pod formation and better pod filling, particularly in soils deficient in Calcium and Sulphur.

Therefore, among the given options, Groundnut is the crop in which gypsum application is required more.
