Burning crop residue after harvesting of wheat crop to minimize obstruction in sowing of succeeding crop is a common practice of Malwa plateau being used in approximately one lakh ha in Shajapur, alone, which deteriorates soil health. Wheat is a main crop of Rabi after gram. Crop residues effect on yield of soybean were studied at farmers field under on farm trial (OFT) program in 2008 and 2009 with following treatments such as (a) in situ mixing of wheat crop residue by the rotavator (CRMR) and (b) burning of wheat crop residues in the field (CRB). Observation revealed that increasing pattern of organic carbon from 0.38 to 0.40 % in two years which is main source of microbial activity which ultimately enhances nutrient availability in field and produced higher grain yield in CRMR i.e., 38.93% higher than CRB.
