| dc.description.abstract | Energy is the key input in an agricultural production. Crop yield dependent upon both direct and indirect energy sources i.e. human beings, fuel, electricity, seed, fertilizer, chemical, and machinery. Paddy-wheat is the major crop rotations in Tarai region of Uttarakhand and production system of both the crops is highly mechanized. The study also compares energy requirement in raising paddy and wheat crops using more efficient methods and equipment. An attempt has therefore, been made in the experimental, commercial and farmer’s field to analyse the energy requirements in paddy and wheat crop production in Tarai region of Uttarakhand. The total energy requirement in paddy cultivation was observed as 32278.8, 23985.6, 25341.4, 25802.9, 26228.5 and 31728.7 MJ/ha with corresponding crop yield of 5.27, 7.67, 8.03, 9.11, 9.30, 9.71 t/ha under the treatment DSR (TP1), transplanting in unpuddled soil (TP2), transplanting in puddled soil with paddy harrow (TP3), rotavator (TP4), spiked puddler (TP5) and combination of paddy harrow, rotavator, patela (TP6), respectively. The requirement of electrical energy was highest in all treatments which was used for operating irrigation pumpset. The energy productivity and energy ratio for high yielding practices has been found to be 0.35 kg/MJ and 5.21 in treatment TP5 with a yield of 9.3 t/ha whereas at a yield of 9.71 t/ha in farmer’s field in (TP6), the energy productivity and energy ratio was 0.3 kg/MJ and 4.49 respectively. The production of paddy crop in a larger area TP5 (4.8 ha) and TP6 (8 ha) indicated the consumption of diesel at the rate of 84.2 l/ha and 117.9 l/ha. The total energy requirement in wheat cultivation was observed as 18146.0, 18650.9, 16646.3, 16745.5, 18491.3, 19132.7, 19760.3 and 21833.6 MJ/ha and the crop yield was 2.96, 3.32, 3.46, 2.75, 2.80, 3.21, 4.70 and 6.20 t/ha under the treatments TW11, TW12, TW13, TW2, TW3,TW4, TW5 and TW6, respectively. The highest share of energy in all treatments was found be from fertilizer. Comparing the wheat crop production in a large area i.e. 4.8 ha in treatment TW5, (commercial field) and 8 ha in treatment TW6, (farmer’s field), the energy productivity and energy ratio were 0.24 kg/MJ and 3.5 in with a yield of 4.7 t/ha and 0.28 kg/MJ and 4.17 with a yield of 6.2 t/ha respectively. The average diesel consumption was found to be between 75 to 86 l/ha for the above treatments. | en_US |
