 ABSTRACT

The experiment was carried out during summer season at Agriculture Research Farm, Bagusala, M.S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi, Odisha in 2018-19. The experimental soil was sandy clay loam in texture, acidic in reaction with low in available nitrogen and high in both phosphorus and potassium. The twelve treatments with combination of irrigation regime and dates of transplanting were tested in split-plot design with three replications. In main plot, the treatments were consisted of three irrigation regimes namely continuous ponding, continuous soil saturation and saturation after hair crack.  Four different transplanting dates such as 23rd and 31st January and 6th and 13th February were assigned in sub plots. The experiment results revealed that all the energy parameters like gross energy output, net energy, energy productivity, energy use efficiency and energy intensity in term of economics were significantly influenced by irrigation regimes, dates of transplanting and their interaction effect. The highest value of energy input, gross energy output and net energy were noticed with continuous ponding while energy use efficiency and energy productivity were recorded under saturation after hair crack. The energy intensity in term of economics was enhanced on continuous soil saturation. Transplanting of rice on 31st January produced maximum all energetic parameters over other dates of transplanting.
