Effect of variousEnergy inputs on Energy requirement for Wheat Production in Agro-Climatic Region (Kamore plateau and Satpura Hill), M.P. India

摘要

Energy in agriculture is important in terms of crop production and agro processing for value adding. The energy requirement in various facets of agriculture varies considerably due to variation in the technology level adopted by the farmers and also because of the diverse agro-climatic conditions. The increased use of inputs such as fertilizer, irrigation water, diesel, plant protection chemicals, electricity etc. demands more energy in the form of human, animal and machinery. The aims of this study were to determine direct input energy and indirect energy in Kamore plateau and Satpura HillRegion,which belongs to wheat-rice zone of Madhya Pradesh, to investigate the efficiency of energy consumption. Data were collected from 120 farmer of Agro-Climatic Region by using a face to face questionnaire method. The results revealed that wheat production in year of 2010-11 consumed a total of 14345MJ/ha of which chemical fertilizer, diesel fuel and electric energy consumption was 31.1%, 20.5% and 24.2%, respectively. Direct and Indirect energy were 49.6% and 50.4% respectively. Output Energy was 56595 MJ/ha. Output¨C input energy ratio and specific energy of production and productivity were 3.9, 3.7 MJ/kg and 0.27 kg/MJ, respectively. The use of commercial source is too high as compared to non-commercial energy sources. Commercial sources contributed about 93.4 per cent of total energy (14345 MJ/ha).On the basis of linear programming the prediction of energy requirement for different levels of yield reveals that there exist a significant scope to enhance wheat productivity through increased use of input energy through fertilizer and machinery. This is mainly due to the reason that still agricultural farms of Madhya Pradesh are applying 50-75% of recommendation of fertilizer and machinery use
