ENERGETICS OF RICE-RATOON-GREEN GRAM PRODUCTION SYSTEM IN COASTAL ODISHA
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 9
Abstract
Field experiments were carried out to study the influence of sowing time of rice and green gram, system of cultivation of rice genotypes on yield and energetics in coastal Odisha during 2009-10 and 2010-11 in split split-plot design. In the main plots, plant rice was sown by 20 June, 5 July and 20 July followed by green gram sown by 2 January, 17 January and 1 February after stubble crop of rice. Three systems of cultivation of rice viz. Best Management Practice (BMP), System of Rice Intensification (SRI) and Modified SRI (MSRI) were assigned in the sub-plots and; hybrid Ajay and cv. Tapaswini in the sub sub-plots, giving rise to 18 treatment combinations that were replicated thrice. Plant rice sown by 20 June so also its ratoon yielded the highest grain and straw with the highest energy output which however declined with subsequent fortnightly delay in sowing. MSRI recorded significantly the highest yields as well as energy output followed by SRI and BMP in sequence. The hybrid Ajay performed better with higher grain and straw yield with significantly more energy output. The rice equivalent yield followed the similar trend so also the energy output in rice-ratoon-green gram system of production in coastal Odisha.
