Mechanization in Indo-Gangetic plains of India is increasing progressively for the past decades. Use of energy intensive inputs is increasing in a modern intensive agricultural production system. The effect of energy intensive inputs are directly associated with the cost of crop production and environmental issues. These necessities the need of energy input – output analysis. This paper presents the energy input-output analysis of rice (Oryza sativa L.) – wheat (Triticum aestivum L.) cropping system studied at Indian Institute of farming system research, Modipuram from 2011 to 2014. Results reveal the variations in energy consumption from rice (25819.4 MJ/ha) and wheat (17714.9MJ/ha). Nitrogenous fertilizer (25-33%), fuel (6.8-18.2%) and irrigation water (8.6 - 23.7%) consumed the bulk of the input energy in rice and wheat. | Energy budgeting and sensitivity analysis of rice Oryza sativa Wheat Triticum aestivum cropping system in indogangentic plains of India
