Effect of PSM, FYM and sludge on effectiveness of Bradyrhizobial strains towards yield and nutrient uptake by mungbean

A field experiment was conducted during kharif season at Agricultural Research Farm of Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, to study the impact of phosphate solubilizing micro-organisms, cattle dung manure and digested sludge on effectiveness of Bradyrhizobial strains on yield and nutrient uptake by mungbean. The experiment was consisted nine treatments combinations viz. control, Bradyrhizobium (M05), Bradyrhizobium (BM1), Bradyrhizobium (M05) + PSM, Bradyrhizobium (BMl) + PSM, Bradyrhizobium (M05) + CDM, Bradyrhizobium (BMl) + CDM Bradyrhizobium (M05) + Sludge ,Bradyrhizobium (BMl) + Sludge with 3 replications in randomized block design (RBD). The nitrogen was applied @10kg/ha through urea as per starter dose while 20 kg P205/ha through single superphosphate as basal application. The seed was inoculated with molybdenum @ 20 g/ha through sodium molybdate with sticker solution. The results revealed that all the Bradyrhizobial strains treatments gave significant increase in the grain and straw yields of mungbean over the control. Among all the treatments Bradyrhizobium (M05) + CDM gave the maximum yields over other treatments Similarly the nutrient uptake was also affected by the different combinations and Bradyrhizobium (M05) + CDM recorded the maximum uptake of N, P, K, S and Fe by grain as well as straw.
