Energy assessment of different tillage with nutrient management practices in rice-linseed cropping system

Abstract

In rice-linseed cropping system, intensive tillage operations, which consume a huge amount of energy in the form of fuel and labor, are carried out harvesting of rice crop. Modification in tillage practices may not only reduce energy consumption but also could make the system more dynamic and efficient. Results reveled that the tillage with nutrient management practices, treatment T2: CT-TPR 100% RDF + 2 t FYM gave significantly highest input energy, output energy and net energy, energy output-input ratio, energy productivity and profitability of rice and T7: ZT-DSR 100% RDF recorded significantly higher specific energy of rice and energy intensity in physical term and T8: CT-DSR 100% RDF + 2 t FYM in case of energy intensity in economics term, which was at par to T5: CT-DSR 100% RDF + 2 t FYM in case of output energy and net energy. As compared to treatment of T7: ZT-DRS + 100% RDF in case of energy output-input ratio, energy productivity and profitability. Moreover, was at par to treatment of T3: CT-TPR 100% RDF (75% inorg + 25% FYM), T1: CT-TPR 100% RDF, T6: CT-DSR 100% RDF (75% inorg + 25% FYM), T5: CT-DSR 100% RDF + 2 t FYM and T4: CT-DSR 100% RDF in case of energy output-input ratio and energy profitability and during 2018 in case of energy productivity. T8: ZT-DSR 100% RDF + 2 t FYM, T9: ZT- DSR 100% RDF (75% inorg + 25% FYM), T5: CT-DSR 100% RDF + 2 t FYM and T4: CT-DSR 100% RDF in case of specific energy of rice and energy intensity in physical term. T5: ZT-DSR 100% RDF + 2 t FYM in case of energy intensity in economics term during 2019 and on mean basis. While the lowest value was noted under T9: ZT-DSR 100% RDF (75% inorg + 25% FYM) in case of input energy, output energy and net energy.
