Abstract:
An investigation on “Water requirement of groundnut under different intercropping system and WUE in groundnut equivalent rate” was carried out at Agro Climate Research Centre, Tamil Nadu Agricultural University, Coimbatore, during winter 2016 and summer 2017. Arachis hypogaea) intercropped with red gram (Cajanus cajan), maize (Zea mays) and castor (Ricinus communis) at different irrigation levels. The groundnut equivalent yield WUE was more under intercropping treatments C₃ (groundnut with maize) and it was par with C₂ (groundnut + red gram). Under 400mm of irrigation water in addition to sprout and life irrigation, it is possible to harvest 11.34 kg of groundnut yield equivalent during winter under groundnut + maize inter cropping system, while the value was 10.71 for summer season. This groundnut + maize intercropping system were followed by ground nut + red gram in giving higher groundnut yield equivalent water use.
