Field experiment with different rice based cropping systems, viz. rice–rice, rice–mustard, rice–chickpea, rice–green gram, rice–sorghum, rice–maize, rice–black gram, rice–cowpea (fodder), rice–sorghum (fodder) were evaluated with rice–rice at RS & RRS, Rudrur, Nizamabad, PJTSAU, Telangana. Green manure–rice–maize and green manure–rice–fodder sorghum produced 15,848 kg REY/ha and 15,292 kg REY/ha respectively, which was significantly more than other cropping systems. Production efficiency of green manure–rice–maize was significantly more (58.26 kg/ha/day) closely followed by green manure–rice–sorghum (54.32 kg/ha/day) and green manure–rice–black gram (54.04 kg/ha/day), while it was lower for green manure–rice–fodder cowpea (39.16 kg/ha/day) and green manure–rice–fodder sorghum (42.09 kg/ha/day). Green manure–rice–maize, green manure–rice–black gram and green manure–rice–fodder sorghum were at par with each other for system net returns with 202,341 Rs/ha, 199,916 Rs/ha, 189,623 Rs/ha respectively, and was least with green manure–rice–fodder cowpea (124,981 Rs/ha) and green manure–rice–rice (148,937 Rs/ha). Energy productivity was higher with green manure–rice–black gram (1.13 kg/MJ) and green manure–rice–green gram (0.91 kg/MJ) cropping system. Green manure–rice–maize, green manure–rice–blackgram are most suitable cropping systems over existing green manure–rice–rice cropping system for vertisols of Telangana state.
