Effect of Calcium and Sulphur Based Fertilizers on Yield and Quality of Ground Nut in Red and Lateritic Belt of Bankura District of West Bengal

Abstract

Groundnut is an important crop in Bankura district of West Bengal growing in kharif season. Among the different varieties of ground nut (TAG 24, TG 37A and TG 51) TG 51 performing better over others, but still required some improvement in yield and quality. In this context, an On Farm Trial was designed to increase yield and quality of ground nut seed by application of recommended fertilizers along with some micro-nutrients for consecutive four years as the soil is deficient of micro-nutrients like Ca and S, which essential for ground nut production. It was found that Var. TG51 gave maximum yield, when the crop was supplied with NPK (20-60-40 kg/ha) in the form of Straight fertilizer Urea, SSP, MOP + 200 kg Gypsum during 30 DAS + 15 kg Sulphur during pegging and regarding quality improvement on oil content was improved by application of sulphur 25kg/ha. Seed germination was improved by application of recommended doses of NPK (20-60-40 kg/ha) in the form of composite fertilizer IFFCO-10:26:26 + 400 kg Gypsum/ha in two split doses @ 200 kg at 30 days after sowing and at the time of Flowering.
