Abstract

A field experiment was conducted to find out the effect of rhizobial strains (Uninoculated, Tal 442 and MO 5), and sulphur (S) levels (15, 30 and 45 kg ha^-1) on mungbean cultivars (SML-668, Pusa Vishal, and HUM-1). Rhizobium strains, at par among themselves, and significantly superior over uninoculated. Cultivar HUM-1 and application of 45 kg S ha^-1 recorded higher plant height, primary branches, green trifoliates, leaf area index, dry matter accumulation, nodule numbers and nodule dry weight, increased days to maturity, number of pod and higher grain and straw yield as compared to cultivars Pusa Vishal and SML-668, and S application at 15 and 30 kg ha^-1, respectively. Nodule number was highest in HUM-1 × MO 5 and application of 45 kg S ha^-1 in Pusa Vishal and HUM-1. Maximum dry matter recorded with HUM-1 × 45 kg S ha^-1. Strain MO 5 showed maximum grain protein irrespective of cultivars and sulphur levels.
