Abstract
Abstract This study investigated the effect of 12 herbicide applications and hand weeding (once, twice, and repeated) in comparison with a weedy control on seed and total crop biomass yield of lentil ( Lens culinaris ) in 2000 and 2001 under the dry conditions of Erzurum (29°55'N and 41° 16'E at an altitude of 1850 m), Turkey. In both growing seasons, data were collected on the density and dry weight of weed species, density of lentil, seed yield, total crop biomass yield, and harvest index. Weed control applications significantly decreased density and dry weight of weeds and increased total crop biomass and seed yields by 49.2% (linuron plus prometryn) and 74.9% (prometryn plus fluazifop‐p‐butyl), compared with the unweeded control. Pre‐emergence plus post‐emergence combinations, however, gave no clear advantages over single applications of linuron, prometryn, and metribuzin. Metribuzin reduced plant density in wetter conditions of the second year. In conclusion, linuron and prometryn alone were effective in controlling weeds on lentils without apparent toxic effects. Hand weeding once was equally effective.
