Monocropping is the practise of cultivating the same crop every year which affects production and soil quality because of this, a stationary field experiment was conducted. Ten cropping systems were tested during the Kharif season in a field experiment at JNKVV, Rewa (Madhya Pradesh). The soil had texture silty clay loam, a pH of 7.25, medium levels of organic carbon (0.56%), moderate levels of nitrogen (224 kg/ha), phosphorus (8.20 kg/ha) and high levels of K (315 kg/ha) that was readily available. The most sound grains possible/ panicle were noted in garlic-rice followed by berseem-rice and chickpea-rice cropping systems. Rice produced the most grains 52.76 q/ha in berseem-rice followed by 52.37q/ha potato-wheat-rice and these farming techniques provided 12.5 % to 16.13 % higher grain yield over existing wheat-rice system. These cropping systems availed 15.45 % to 15.97 % higher gross return and 27.1 % to 29.48 % higher net return than existing wheat-rice system. The B: C ratio 2.46 was most in mustard-green manure-rice cropping system followed by 2.42 in potato-wheat-rice and 2.41 in berseem-rice cropping system.

Cropping Systems, B: C Ratio, Gross Return and Harvest index

The rice crop performed superior in berseem-rice, potato-wheat-rice, mustard-green manure-rice and garlic-rice cropping system. These cropping systems provided better growth yield contributing characters and increased the yield of rice by 12.5 % to 16.13 % higher as compared to existing wheat-rice cropping system. Berseem-rice was the best cropping system out of all the others. Additionally, rice crop performed better in potato-wheat-rice system as compared to existing system. Mustard-green manure-rice cropping system gave most net return and benefit cost ratio proceeded by potato-wheat-rice and berseem-rice. The rice crop did better under residual effect of this cropping pattern as compared to existing wheat-rice system.
