Abstract:

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. Rice crop with the higher energy output produced higher energy use efficiency (7.6), energy use efficiency for grain (4.1) net energy (171399.2) and energy profitability (0.28), while the human energy profitability (162.9) was higher in wheat indicating that it was more labour energy efficient than rice. The consumption of direct (6522.7MJ/ha) and indirect energy (19296.8MJ/ha) was found higher in rice crop. Econometric model estimation emphasized that direct energy was found more positive on increasing rice and wheat yield. Thus sensitivity analysis also indicated marginal physical productivity of 0.96. Both rice and wheat were found energy intensive; in order to reduce the energy consumption crop diversification and farm mechanization would be the possible solution.
