Cropping system analysis for agricultural sustainability - productivity, economy, ecology and energy use efficiency

Field experiment was conducted during 2012-2013 and 2013-2014 at the Zonal Adaptive Research Station, Krishnagar, Nadia, West Bengal to find out alternative remunerative cropping systems in comparison to existing rice-rice and rice-wheat system through crop diversification and intensification in the Eastern Gangetic plain.Result of study revealed that the productivity of different cropping systems was in the order of jutepotatorice > ricepotato -rice> ricepotatosesame > juterapeseedrice > jutericerice > ricerapeseedrice > jutewheat > ricerice > ricewheat.Further, results of study suggest that jutepotatorice, ricepotatorice and ricepotatosesame are suitable for large and medium farmers but these systems have higher energy productive at the cost of higher consumption resulting lower energy productivity.Moreover, for small and marginal farmers Jutewheat and juterapeseedrice cropping system considered suitable because of their moderate cost of production and net return..
