Effect of Sulpher Levels on Mustard (Brassica juncea) yield in Muzaffarpur district of Bihar
A field experiment was conducted to find out the effect of phosphorus, sulphur and PSB on growth attributes and yield of Vigna radiata. The experiment consisted four levels of phosphorus (0, 20, 40 and 60 kg h-1) and three levels of sulphur (0, 20, and 40 kg h-1) and seed non-inoculated and inoculated with PSB. Increasing level of phosphorus up to 60 kg ha-1 and sulphur up to 40 kg ha-1 gradually increases the plant height and significantly increases the number of pod plant-1, number of grain per pod-1, grain yield h-1 and stover yield. Seed inoculated with PSB showed superior plant height, significantly increases the number of pod plant-1, number of grain per pod-1, grain yield h-1 and stover yield. In similar proportion net return also increased with increase in the level of phosphorus, sulphur and seed inoculation with PSB.
