Values in parentheses are per cent increase over control by the respective treatments SC/SP
Control* where only sterilized peat was applied without any bacterial inoculum, IC strain name of rhizobia used in the study, SC seed coating, SP seed priming, RP rock phosphate
aMeans are significantly different by SC and SP method at P = 0.05 when compared by LSD
