Unavailability of irrigation water and labour encouraged the rice farmer to shift from traditional transplanting to direct seeding. The experiment conducted in clay loam soil of College farm during kharif season and it consists of four irrigation levels and six integrated weed management practices laid in Split plot design. The available nitrogen and phosphorus content was low and the potassium content was medium. Higher grain yield (2102 and 2486 kg/ha) and harvest index (35.3 and 35.8%) with IW/CPE ratio of 2.0 and 1.5 due to more applied water encouraged in better crop growth as higher plant height, tillers/m2, dry matter production, lea area index and also increased in yield attributes as panicle length, filled grains/panicle, test weight. Similarly lower weed density and high weed control efficiency recorded with application of pendimethalin or butachlor @ 1.0 kg/ha as pre-emergence fb metsulfuron methyl + chlorimuron ethyl @ 4.0 g/ha at 25 DAS + MW fb HW at 45 DAS influenced on higher grain yield (2097 and 2032 kg/ha) and better harvest index (33.3 and 34.1%) and interaction effect shown on crop growth and yield. Application of fenoxaprop-p-ethyl @ 60 g/ha as post-emergence recorded lower growth and yield which was higher than unweeded control.
