Effect of sulphur fertilization on yield and economics of gingelly (Sesamum indicum) in Typic chromustert

Abstract

A field experiment was conducted in a farmer’s field at K. Vellakulam village in Kalligudi block, Madurai district to study the effect of sulphur on the yield and economics of sesame in Typic Chromustert. The experimental field was laid out by following randomized block design (RBD) with thirteen treat mental combination. The sulphur was applied as FeSO4 and gypsum at various levels (20,40,60 kg ha-1) as soil application and K2SO4 as foliar spray (0.5%). The results revealed that application of sulphur as FeSO4 @ 40 kg ha-1 + Foliar application of K2SO4 @0.5% at 20,40 DAS along with N,P2O5,K2O on STCR basis registered the highest grain yield (836 kg ha-1) as well as stalk yield (2558 kg ha-1) compared to gypsum application. This was statistically at par with the treatment in which sulphur was applied as FeSO4 @60 kg ha-1 with recommended dose of fertilizer.
