A field experiment was conducted to evaluate the influence of different sulphur sources at various levels on growth and grain yield of green gram in Alfisolof Madurai district, Tamil Nadu during kharif season in the year 2018. Four sources [Ammonium sulphate (S1), Potassium sulphate (S2), Magnesium sulphate (S3) and Calcium sulphate (S4)] at four different levels [0 (L1), 20(L2), 40(L3), 60 (L4) kg ha-1] applied along with recommended source of fertilizer (RDF) were designed for the study. The experiment was replicated thrice following factorial randomized block design (FRBD). The results showed that the combined effect of RDF with calcium sulphate at the level of 40 kg ha 1 had a considerable enhancement of crop growth, yield attributes and yield of green gram in Alfisol. Among the different treatment combinations, the highest and appreciable crop growth, yield attributes and maximum grain yield of 1297 kg ha-1green gram was recorded in the combined treatment, L3S4 (calcium sulphate at 40 kg ha-1+RDF) and the lowest values of all parameters were observed in the control (L1).
