Abstract
A field experiment was conducted during 201012 at Pundibari, Cooch Behar, West Bengal, to analyse crop- ping systems in energy terms and to evaluate alternative solutions, especially for arable crops. The trial was car- ried out in a split-plot design with 2 main-plot (tillage), 2 subplot (mulching) and 4 sub-subplot treatments (INM). The highest net energy value was obtained with the conventional system, and the lowest with the conservation system. With respect to the treatments in maize (Zea mays L.)blackgram [Vigna mungo (L.) Hepper] cropping system, conventional tillage produced the 3 years highest output energy (264.47 103 MJ/ha). Maize was the crop that contributed much to the total output energy in the tillage systems, followed by blackgram. The highest benefit: cost ratio (1.73) was observed at zero tillage. Conservation tillage, mulching and application of vermicompost by partial replacement of chemical fertilizer opened up the better scope of energy conservation within the system by renewable sources.
