Abstract

Energy is one of the most valuable inputs in agriculture. It is being invested in various forms such as mechanical, chemical, electrical etc. The amount of energy used in agricultural production, processing and distribution should be significantly higher in order to feed the expanding population and to meet other social and economic goals. Agriculture in a way is an energy conversion industry. Energy use in agricultural production has been increasing faster than that of in many other sectors of the world economy because agricultural production has become more mechanized and commercial fertilizers dependent. Energetics is an approach to gauge, quantify and determine relationship between input and output energy to augment energy use efficiency and crop productivity. The study of energetics, which is relatively a stable index unlike economics of production, assumes paramount importance in the present era of energy crisis. It can be used to evaluate a given cropping system. The approach reduces the various factors and forces involved in a cropping system for energy units and describe the production process as energy transformation. In agriculture, because of the multi-stage character of production processes, the question of energy efficiency of production technologies becomes important.
