Abstract
Sulfosulfuron at 33.3 g/ha recorded significantly lower weed intensity and biomass, higher weed control efficiency, which was at par with hand weeding 30 DAS and superior to isoproturon and 2,4 D sodium salt. The maximum nutrient removal by wheat crop and response over weedy check towards grain yield of wheat (129.6%) were with weed free treatment followed by sulfosulfuron at 33.3 g/ha and minimum in 2,4-D of sodium salt at 0.80 kg/ha. The maximum net return and B: C ratio by wheat cultivation (` 31,475/ha and 1:1.80) was obtained with sulfosulfuron at 33.3 g/ha at par with weed free and weeding at 30 DAS than others treatments.
