Abstract

An experiment was conducted during the kharif season of the year 2003 to study the effect of potassium and sulphur on growth and yield of black gram (Vigna mungo L. Hepper) under rainfed condition. There was a significant effect of potash and sulphur levels on plant height, number of branches per plant, number of pods per plant, length of pod, 100-grain weight, straw yield and grain yield. Significantly the highest grain yield (9.17 q ha−1) and straw (18.28 q ha−1) yield was recorded under 20 kg K2O ha−1, which was at par with 40 kg K2O ha−1 in case of grain yield. Application of sulphur at 30 kg S ha−1 (S2) registered significantly the highest grain (9.19 q ha−1) and straw (18.06 q ha−1) yield. Combined application of 20 kg K2O ha−1 along with 30 kg S ha−1 recorded significant increase in respect of yield attributes and yield.
