Effect of Sulphur and Biofertilizers on nutrient contents and uptake by blackgram (Phaseolus mungo L.)


Amit Kumar Saket, Sonu Rahi

A field experiment was conducted during rainy seasons of 2017 and 2018 to study the effect of sulphur and biofertilizers on nutrient contents and uptake of blackgram. The nutrient contents in grain and straw viz., N, P, K and S deviated significantly due to sulphur levels and biofertilizers as well as their interactions. The highest sulphur level (60 kg/ha) and dual biofertilizers (Rhizobium + PSB) resulted in almost significantly higher N, P, K and S contents and their uptake of blackgram. The highest total uptake of nutrients by blackgram producing a total biomass upto 32.24 q/ha with highest S level was 102 kg N, 12.28 kg P, 53.18 kg K and 5.63 kg S/ha. Similarly, under dual biofertilizers, the corresponding uptake values were 100.4 kg N, 11.14 kg P, 42.30 kg K and 5.52 kg S/ha under 33.4 q/ha total biomass. The findings suggest that due to heavy withdrawal of nutrients by blackgram cv. JU-2, the succeeding crop must be nourished properly based on nutrients status of the soil.
