College of Agriculture, Sehore (India) Field experiment were conducted for three consecutive years in the Kharif season of 1998-99, 1999-2000 and 2000-2001 at Research Farm of R.A.K. College of Agriculture, Sehore (M.P.). The findings revealed that the combined inoculation of Pantnagar 2 + Delhi 2 + Bj-1 rhizobial strains yielded the significant highest symbiotic traits viz. nodule number, their dry weight and shoot dry weight/ plant alongwith seed index (100 seed weight) and seed yield of Soybean over uninoculated control. The dual inoculation of Pantnagar 2 + Bj-1 rhizobial strains produced the significant symbiotic traits alongwith seed index and seed yield except the nodule dry weight/plant. Amongst the alone strains, Delhi -2 strain, produced the siginificant highest nodule dry weight, seed index and seed yield while the significant higher nodule number and shoot dry weight have fetched through the incorporation of Bj-1 rhizobial strain alone over control in clay loam soil. https://www.biotech-asia.org/vol3no2/response-of-effective-rhizobial-strains-and-their-combination-on-symbiotic-traits-and-yield-of-soybean-under-rainfed-conditions-of-m-p-india-2/ Rhizobial strain; Symbiotic traits; Soybean
