Summer moong was grown in field for two years with application of elemental sulphur (0, 15, 30 and 45 kg ha−1) on Inceptisol (Udic Ustochrept). Sulphur application improved significantly plant biomass, nodule number and weight, seed and straw yield, nitrogen and sulphur uptake, optimum being 30 kg ha−1. Application of sulphur up to 15 kg ha−1 increased population of total bacteria and Azotobacter. However, addition of sulphur decreased the population of fungi and actinomycetes.
