A field experiment was conducted at main research farm of OUAT, Bhubaneswar, Odisha. The experiment was laid out in double split design with 27 treatment combinations and three replications. In main plot sunflower residue was removed in one plot, incorporated in another plot and in third plot no sunflower was grown. In subplot three methods of establishment of rice was taken namely dry direct seeded, wet direct seeded and transplanting method of rice establishment. Three different nutrient management practices was given to rice in sub sub plot i.e. first is fully organic where only FYM was used as nutrient source, in second one integrated approach was followed through 75 percent of nitrogen through inorganic nutrient source with 25 percent of organic source and the third case is pure inorganic where only chemical fertilizer was given at the rate of 60-30-30 kg of N-P2O5-K2O per ha. After harvest of rice, green gram crop was taken under residual soil moisture and soil nutrient status. Dehydrogenase activity, phosphatase activity, urease activity and total microbial biomass carbon were higher in sunflower residue incorporation and organic source of nutrient.
