Investigations on the Chemical Control of Wild Oats (Avena ludoviciana Dur.) in Irrigated Barley (Hordeum vulgare L.)

Field investigations were conducted at the experimental area of Punjab Agricultural University, Ludhiana during 1994–95, 1995–96 and 1996–97 on loamy sand soil having 88.2, 7.7 and 4.0% of sand, silt and clay, respectively. On an average, highest barley grain yield of 4060 kg ha⁻¹ was recorded in diclofopmethyl (0.90 kg ha⁻¹) after first irrigation followed by tralkoxydim 0.35 kg ha⁻¹ (after first irrigation), isoproturon 0.94 kg ha⁻¹ applied after first irrigation, isoproturon 0.56 and 0.75 kg h⁻¹ applied before first irrigation: and these treatments gave 88.0, 87.0, 75.5, 73.1 and 72.2% more yield than unweeded (control) treatment, respectively.
