Rice residues are important natural resources, and recycling of these residues improves the soil physical, chemical and biological properties. Management of rice straw is a major challenge as it is considered to be a poor feed for the animals due to high silica content. A field experiment was conducted at Agricultural Research Station, Bhavanisagar during 2014-2015 and 2015-2016 to review the suitable rice residue management practices and nutrient dynamics by using combine harvester operated rice field after cultivating rice. In both the years, the results revealed that incorporation of straw as such with tractor mounted with half cage wheel and rotovator with addition of biomineralizer (TNAU microbial consortia) for decomposition of straw and incorporation later followed by 100 percent recommended dose of fertilizers (T3) recorded the highest DMP (8358 and 8609 kg ha-1), no. of tillers M-2 (572 and 589), no. of productive tillers M-2 (400 and 412), filled grains per panicle (168 and 173), 1000 grain weight (20.24 and 20.85g), grain yield (7706 and 7937 kg ha-1) and straw yield (9982 and 10281 kg ha-1).This was followed by incorporation of straw as such with tractor mounted with half cage wheel and rotovator with 25 kg additional dose of N ha-1 as basal.
