Cropping system analysis for agricultural sustainability, productivity, economy and land use efficiency of different rice based cropping systems in Chhattisgarh plains

Abstract

A field experiment was conducted at the Research-cum instructional farm, College of Agriculture, Raipur (C.G.) during 2020-21 and 2021-22. The experiment was laid out in randomized block design consists three replications with ten treatments of rice based cropping systems were i.e. rice(MTU 1010)-wheat-green manure; rice(MTU 1010)-chickpea-fallow; rice(Dubraj)-garden pea-cowpea(veg.); rice(Devbhog)-cowpea(veg.)-moong; rice(Zinco rice)-mustard-moong; rice(Protazin)-french bean-groundnut; rice (Badshah bhog)-berseem-sorghum; rice(Vishnubhog)-oat-pearl millet; rice(Hybrid US 312)-sweet corn-tomato+coriander(1:1); rice(Hybrid Arize Gold)-cabbage-sweet corn+cowpea(veg.)(1:1). The results revealed that maximum total productivity of the system in terms of REY was recorded under rice((Hybrid US-312)-sweet corn-tomato+coriander (1:1) cropping sequence in both the years (242.7 and 247.7 q ha-1). The highest production efficiency and economic efficiency were registered in rice (Hybrid US-312)-sweet corn-tomato+coriander (1:1) cropping system as compare to other rice based cropping systems during both theyears and on mean basis. Land utilization efficiency was recorded maximum under rice (Badshah bhog) -berseem-sorghum cropping system during both the years and on mean basis. Maximum total cost of cultivation, total gross returns and total net returns were registered under rice (Hybrid US-312)-sweet corn-tomato+coriander (1:1) cropping system (Rs 181245 ha-1, Rs 193674 ha-1 and Rs 187460 ha-1 respectively) on the mean basis. B:C ratio (3.02, 2.64) was registered maximum under rice (MTU 1010) – chickpea – fallow cropping system during the first year and on mean basis. However, during the second year the maximum B:C ratio (2.38) was under rice(Protazin)- french bean – groundnut cropping.
