Weed Management Studies in Direct - seeded upland Rice Under Haryana Condition¹

Field studies were conducted at the Haryana Agricultural University, Hisar during rainy season of 1981 and 1982. Preemergence application of thiobencarb or pendimethalin followed by one hand weeding 30 days after sowing (DAS) reduced the density and dry matter production of weeds better than when these herbicides were used alone. Hand weeding and hand hoeing 15 and 30 DAS proved more effective in controll-ing weeds and resulted in higher grain yields as compared to the use of wheel hoe. Herbicide application when supplemented with one hand weeding 30 DAS resulted in higher yields of rice than when herbicides were applied alone.
