In-situ Moisture Conservation and Yield of Rainfed Groundnut (Arachis hypogaea L.) as Influenced by Moisture Conservation Practices and Nutrient Management

摘要

An experiment was conducted during kharif 1999 and 2000 to study the influence of different moisture conservation practices and nutrient management on in-situ moisture conservation and yield of rainfed groundnut. Moisture conservation practices involving alternate furrow and bed followed by ridges and furrows registered higher moisture content at 0-15 cm and 15-30 cm depth at all stages of crop growth over flat bed method. Similarly the same treatments recorded significantly higher pod and haulm yields as well as rainfall use efficiency. Plastic mulch and straw mulch also recorded similar positive results in terms of soil moisture content, pod and haulm yield and rainfall use efficiency as was observed in case of land configurations. 100% RDF + IBA@ 50ppm + Urea @ 1% at 40 and 60 DAS (N_3) followed by 100% RDF (N_2) resulted in significantly higher pod, haulm yield and also rainfall use efficiency as compared to control (N_0).
