This study was undertaken to find out the actual situations of energy use level and to identify the energy and land productivity, cost benefit ratio and cropping pattern from diversified cropping systems in the Mymensingh district (Bangladesh). Ten rice-based common cultivable crops were studied. Eight boro rice (HYV winter season rice) based cropping patterns were developed to achieve maximum land productivity in terms of energy and cost from diversified cropping system. Commercial fertilisers were the major energy and costly input sources for all field crop cultivation. Irrigated boro rice consumed the highest energy (about 19,600 MJ/ha). Boro + t. aman + vegetable cropping systems gave higher yields than Boro + t. aman systems in terms of energy outputs and financial recovery. This study revealed that the rice based diversified cropping system resulted in the highest energy and cost return.
