An AICRP experiment was conducted under irrigated condition during 2016-17 at Agricultural Research Station, Siruguppa, University of Agricultural Sciences (UAS), Raichur, Karnataka, India, to study feasibility of alternative cropping system for existing predominant rice – rice system in TBP command area on deep black soil. The experiment consisted of ten cropping systems and laid out in completely randomized block design with three replications. The results revealed that, growing of rice followed by ridge gourd (Kharif-summer) recorded significantly higher Rice equivalent yield (11540 kg/ha), Gross return (Rs.226114/ha), Net return (Rs.157504/ha), B:C ratio (3.30), System profitability (431.5 Rs/ha/day) and System productivity (31.62 kg/ha/day) and followed by rice – coriander cropping system (T6) with respect to gross return (Rs.183209/ha), Net return (Rs.121199/ha), B:C ratio (2.95) and System profitability (332.1 Rs/ha/day) compared to predominant rice –rice cropping system (T1, T9 and T10). The higher N uptake of 134 kg/ha/year and P uptake of 49 kg/ha/year and K uptake of 221 kg/ha/year was noticed in rice followed by rice cropping system (T10). Results indicated that, growing of rice followed by vegetables (Kharif-summer) was best to higher income for the farmers and it improves the soil fertility and productivity compared to only growing of rice followed by rice.
