ECONOMIC FEASABILITY OF ORGANIC MATERIALS IN ORGANIC FARMING OF RICE-BASED CROPPING SYSTEMS

The field experiments were canied out on research farm of Indian Agricultural Research Institute, New Delhi during crop cycles of 2006-2007 and 2007-2008 The experiment was laid out in a strip plot design with three replications. Treatments consisted of two cropping systems (Rice-wheat and rice-wheat-mlmgbean) in columns, six combinations of different organic materials and biofetiilizers [ fatmyard manure equivalent to 60 kg N ha·1 (FYM), vennicompostequivalent to 60 kg N ha·1 (VC), FYM + crop residue of preceding crop @ 6 t ha-1 for rice and wheat and 3 t ha·1 for mungbean (CR), VC + CR, FYM + CR + biofertilizers and VC + CR + biofertilizers] and control (no fetiilizer applied) in rows. Application of vetmicompost + cropresidue + biofertilizers was most productive and FYM + crop residue + biofettilizers was economical for nutrient need of rice-based cropping systems. Rice-wheat-mlmgbean cropping system was more sustainable economically to the traditional rice-wheat cropping system
