Weed Management through Herbicides in Direct Drilled Upland Rice in Rainfed Situations of Southern Rajasthan
1999
Field experiment was conducted in direct drilled upland rice during rainy seasons of 1995 and 1996 to find out effective and economically viable system of controlling complex flora of weeds in rainfed rice. Pre-emergence application of oxyfluorfen at 0.2 kg/ha resulted in maximum WCE of 96.5% but maximum grain yield (14.5 q/ha) was realised at its 0.1 kg/ha level. Post-emergence application of pretilachlor with safener (Sofit) at 0.375 kg/ha with WCE of 94.8% and the grain yield of 11.0 q/ha was the second best. Pre-emergence application of pendimethillin and oxadiazon was also comparable.
