A field experiment was conducted during 2 rainy (kharif), winter (rabi) and summer seasons (2015-17) on a sandy clay loam soil at New Delhi to evaluate 5 cropping systems viz., maize–pea–okra, maize–mustard–green gram, cotton–wheat, bottle gourd–onion and okra–wheat, for productivity, profitability and energetics. The experiment was laid-out in a randomized block design replicated 4 times. Bottle gourd–onion cropping system recorded the highest wheat-grain-equivalent yield (WGEY) of 19.9 t/ha, followed by maize–pea–okra (14.06 t/ha). The lowest WGEY was recorded with maize–mustard–green gram (9.12 t/ha). The gross returns (₹ 313.56x 103/ha), net returns (₹ 123.5x103/ha), benefit: cost ratio (3.23), were also higher with bottle gourd–onion cropping system, while maize–mustard–green gram registered the lowest gross returns, net returns and B: C ratio. The lesser input energy (25.68 x 103 MJ/ha) and higher energy productivity (775.2 g/MJ) was recorded with bottle gourd – onion cropping system. All the five cropping systems can suitably substitute the existing rice – wheat cropping system under marginal farmer’s situations, not only by providing higher productivity and returns, but also provide a regular income throughout the year.
