Production and Cropping System’s Influence on Productivity, Economic Viability and Energetics Under Mid Hill Conditions of Himachal Pradesh
The study was carried out in a continuing experiment under the aegis of Rashtriya Krishi Vikas Yojna at Palampur. Three cropping systems viz. maize- wheat, maize + cowpea- wheat + gram and okra + pole beancabbage + garden pea were evaluated under four production practices viz. integrated nutrient management (INM), organic management (OA), natural farming (NF), and conservation agriculture (CA) for crop productivity, profitability and energetics. Among production systems, INM or CA were more promising in terms of wheat grain equivalent yield (WGEY), net returns, energy output, energy intensity, energy productivity and energy profitability followed by OA and NF treatment in that order. INM and CA production practices increased WGEY by 2.54 and 1.86 times, net return by 6.14 and 5.31 times, energy output by 1.63 and 1.59, energy efficiency by 2.10 and 1.20, net energy by 1.80 and 1.62, energy productivity by 4.0 and 2.0 and energy profitability by 6.8 and 5.70 times, respectively over the NF production practice. Okra + pole bean – cabbage + garden pea gave significantly higher WGEY (13.7 Mg/ha/annum), energy productivity (0.4 kg WGEY/MJ) and energy profitability (INR 616/ha/day). But it had higher cost of cultivation and low yield in kharif thereby lower net returns, B:C, energy output, energy output: input and energy intensity both in terms of MJ/kg and MJ/rupee.
