Determination of Weed Density, Yield and Quality Parameters in Winter and Spring Sown Lentil (Lens culinaris Medik.)

In this study, by using a red lentil variety of Kafkas, it is aimed to indicate the influence of winter and spring sowing weed control methods (no control, one time hand weeding, two times hand weeding and herbicide) on yield and grain quality clearly through the randomized blocks divided plots trail desing method under the rainfeed conditions. According to the obtained results, winter sown and 2 times weed control method gives the highest plant height 29.83 cm, pod per plant 25.40, grain per plant 24.13, plant biological yield 3.56 g, unit area biological yield 819.3 g/m2, grain yield 180.76 g/m2, and 100 kernel weight 3.67 g. But grain protein content 22.52% and first pod height 12.16 cm were obtained from 2 times weed control spring sowing plots. Plant height, first pod height, plant grain yield, plant biological yield, biological yield and grain yield (m2), 100 kernel weight, and grain protein content were affected as statistically by sowing time. On the other hand yield and quality components affected by weed contol methods they are in different groups according LDS test, except 100-kernel weight. Although at plant height parameter, 2 times weed control and herbicide plots were similarity as statistically. When results evaluated, for lentil farming 2 times weed control and winter sowing gives better results in terms of yield components and grain quality.
