The present investigation, entitled “Effect of crop management practices on yield and economics of rice (Oryza sativa L.) cultivars " was carried out at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalay, Raipur (C.G.) during Kharif 2018. The field experiment was laid out in split plot design with three replications and five main plot treatments consist of quality rice cultivars víz VI: Trombay CG Dubraj Mutant-1,V2: Tarunbhog Mutant-1, V3: Safri 17-48-2, V4: Trombay Raipur Rice-106, V5: Zinco Rice and five sub plot treatments of crop management practices (Spacing+ nutrient management) viz P1: 20x10 cm spacing + 100% RDF through inorganic (Standard check), P2: 20x10 cm spacing + 100% RDF through inorganic and organic, P3: 20x10 cm spacing + 150% RDF through inorganic and organic, P4: 15x10 cm spacing + 150% RDF through inorganic and organic, P5: 20x10 cm spacing + 150% RDF inorganic. In case of P2, P3 and P4 top dressing of vermicompost @ 2 q ha + DAP @ 25 kg hat was done at 25-30 DAT and remaining N:P2O5:K2O was applied through inorganic sources. Crop planted at 15x10 cm spacing + 150% RDF through inorganic and organic observed highest grain yield. Lowest grain yield was recorded in 20x10 cm spacing +100% RDF through inorganic (Standard check). Gross return, net return and B:C. ratio was also obtained higher in cultivar Trombay Raipur Rice-106 followed by Trombay CG Dubraj mutant-1 In the same way among the crop management practices, higher gross and net return was achieved under 15x10 cm spacing + 150% RDF through inorganic and organic sources, whereas, the B:C ratio was higher in 20x10 cm spacing+100% RDF through inorganic followed by 15x10 cm spacing + 150% RDF through inorganic and organic sources.
