Abstract

A field experiment was conducted at Instructional Farm of ICAR- Krishi Vigyan Kendra, Tura during kharif, pre-rabi and rabi season of 2011-12 to 2013-14 to determine the suitable production potential, profitability, resource use efficiency and sustainability of diversified maize-legumes cropping system. The five cropping sequences viz., CS1: Maize + Blackgram (1:2) – green gram + maize (2:1) – tomato,  CS2: maize + green gram(1:2) – green gram + maize (2:1) – tomato, CS3: maize + groundnut(1:2) – green gram + maize (2:1) – tomato,  CS4: maize + Ssybean(1:2) – tomato and CS5: maize sole – green gram – tomato were replicated four times using a randomized block design on sandy loam soil with low to medium fertility level and slightly acidic in reaction. The cropping system “Maize + Green gram(1:2) – green gram + maize (1:1) – tomato” was found to be most remunerative and sustainable with system productivity (175.49 q/ha), net return (Rs.3,38,725/ha), profitability (Rs. 928.01 /ha/day), benefit cost ratio (4.40), sustainable yield index (1.00), production efficiency (Rs.58.30/ha/day), relative economic efficiency (162.72%), except land use efficiency(LUE) which was the highest (85.75%) in  “maize + groundnut(1:2) – green gram + maize (1:1) – tomato” cropping system. The lowest system productivity, net returns, profitability, production efficiency, land use efficiency etc was found in maize+ soybean (1:2)- tomato followed by maize-greengram-tomato cropping system. Hence, the cropping sequence maize + green gram(1:2) – green gram + maize (1:1) – tomato  and maize + groundnut(1:2) – green gram + maize (1:1) – tomato were found to be the productive, profitable, remunerative, resource use efficient and sustainable  in the mid hills sub-tropical regions of India.
