Abstract:

Increasing farm labor scarcity and depletion of natural resources such as water are posing threats to the sustainability of traditional Puddled Transplanted Rice (PTR) system in Eastern India. Dry-seeded rice (DSR) or Non-Puddled Transplanted Rice (NPTR) could be used as an alternative to PTR. The use and cost of energy in agriculture have increased, making it necessary to make current agricultural practices more energy efficient. To achieve this, energy indices of rice establishment methods and varying duration rice varieties have been analysed in the present investigation. Fertilizer use accounted for the maximum input energy consumption, accounting for 51.8%, 46.1% and 39.9%, respectively, in DSR, NPTR and PTR system, followed by human labor. The DSR system was more energy efficient with Energy Use Efficiency of 9.6 compared to 8.6 and 7.5 in NPTR and PTR, respectively. The maximum Energy productivity of 0.32 kg MJ-1 and profitability of 8.6 were recorded in DSR. The lower value of specific energy (3.13 MJ
kg-1) under DSR indicated lower amount of energy requirement to produce unit grain yield. Cultivar duration groups did not differ significantly for total energy output and energy indices during both the years. However, cv. ‘Swarna’ had higher total energy consumption than cv. ‘Arize 6444’ and ‘Arize 6129’.
