Field experiment were conducted in chromustert soil (vertisol) for four years in Kharif season of 1999, 2000, 2001 and 2002 at Research Farm of R.A.K. College of Agriculture, Sehore (M.P.). The findings revealed that the inoculation of Soybean seed with PSM-2 alongwith incorporation of FYM @ 1 t/ha + SSP 60 kg P2O5/ha (T5) produced the significant higher nodulation viz. number of nodule/plant (NN/plant), nodule dry weight (NDW/plant), shoot dry weight (SDW/plant), seed index (weight of 100 grams seeds) and seed yield over T1 and control. This treatment also remained superior over rest of the treatments and fetched the highest 38.56 more seed yield as that of rest of the treatments. This indicates the superiority of phosphate solubilizing micro organism (PSM 2) in enhancing the availability of phosphorous alongwith other essential nutrients in the soil leading to higher nodulation and seed yield of Soybean in Central India.
