Comparative study on combined and individual effects of farmyard manure and green-manuring with fertilizer N on growth and yield of rice (Oryza under sativa) submergence-prone situation
Year: 2001
Type: article
Abstract: A field experiment was conducted during 2003 and 2004 to study the combined and invidual effects of using farmyard manure (FYM), green-manure (dhaincha : Sesbania aculeata L.) along with fertilizer N on rice (Oryza sativa L.) variety 'Gayatri' experiencing 10 days' complete submergence at maximum tillering stage. The crops under both the organics (FYM and green-manuring) thrived better under submergence, due to greater root de- velopment, higher critical N level in plant, higher biomass production and less tiller mortality compared with their individual application. Consequently these crops gave significantly higher grain yield (3.03 tonneslha). The crops under both the organics ensured higher N uptake (55.50 kglha), apparent N recovery (38.32%) and N-use effi- ciency (29.50 kg grainlkg N applied).
