Energy Input-Output Analysis for Production of Wheat under Different Planting Techniques and Herbicide Treatments

Abstract

The assessment of the energy requirements of the different planting techniques and herbicide treatment was carried out at Agronomy farm area, CCS Haryana Agricultural University, Hisar, Haryana, India with five planting techniques i.e. drill sowing at 20 cm, 18 cm and 16 cm, bed planting with three and two rows and five weed management treatments i.e. pinoxaden 50 g/ha, RM of carfentrazone and metsulfuron 25 g/ha, pinoxaden 50 g/ha + RM of carfentrazone and metsulfuron 25 g/ha, weed free and weedy check. Among different planting techniques, drill sowing with 18 cm is most efficient method in respect of energy calculations (NE, EUE, energy profitability, specific energy, energy productivity, energy intensiveness, energy intensity in physical terms, energy intensity in economic terms) followed by three row bed planting and 20 cm row spacing. This may be attributed to total energy output (grain + straw). Tank mix application of pinoxaden (50 g/ha) with RM of carfentrazone and metsulfuron-methyl is very efficient in terms of energy and recorded higher value of different energy calculations (EUE, energy profitability, specific energy, energy productivity, energy intensiveness, energy intensity in physical terms, energy intensity in economic terms).
