Abstract:
This study aims at finding the input–output energy use and the relationship between energy input levels on wheat yield in Saurashtra region of Gujarat, India. Besides, the energy analysis was carried out based on different farm operations. Data were collected from 605 farmers (small marginal farmers 287, medium marginal farmers 288, and large marginal farmers 30) using face to face questionnaire method. The source wise total energy input consumption was 25327.58, 32043.23 and 55549.24 MJ for small, medium and large marginal wheat farmers; in which Irrigation with 11000.54 (43.43 %), followed by fertilizer application and sowing (with 24.84% and 16.67%) were highly contributed to the total energy use for small marginal farmers. For medium marginal farmers; Irrigation with 10835.27 (33.81%), followed by fertilizer application and sowing (with 28.24% and 20.68%) were highly contributed to the total energy use and for large marginal farmers; fertilizer application with 17597.66 (31.68%) followed by sowing and irrigation (with 25.30% and 19.12%) were highly contributed to the total energy use however the total physical energy input consumption was 19203.81, 32043.23, 55549.24 MJ for small, medium and large marginal wheat farmers; in which water with 5817.59 (30.29%) followed by electricity and nitrogen (27.85% and 16.30%) were highly contributed to the total energy use for small marginal farmers. For medium marginal farmers; nitrogen with 8017.21 (25.02%), followed by electricity and seed (18.59% and 17.53%) were highly contributed to the total energy use and for large marginal farmers; nitrogen with 15333.88 (27.60%) followed by seed and diesel fuel (with 21.57% and 13.81%) were highly contributed to the total energy use. Energy ratio, energy productivity and net energy were higher in large marginal farmers with 3.97, 0.27 kg/MJ and 165095 MJ respectively while specific energy was found higher for small marginal wheat farmers with 0.52 MJ/kg. Nitrogen, pesticide and electricity positively significant while diesel fuel is negatively significant with 54% R2 for small marginal farmers; potassium, human labour, machinery and water positively significant while fym is negatively significant with 54% R2 while for large marginal farmers, human labour and electricity negatively significant with 45% R2.
