Response of Bread Wheat Cultivar to Different Sowing Densities for Yield and Yield Traits

This study was conducted at Edirne, Tekirdağ and Kırklareli locations in the 2017-2018 growing season in a randomized block design with four replications. In the study, it was aimed to determine the effects of five different sowing densities (200, 300, 400, 500 and 600 seeds/m2) on the grain yield and yield components of bread wheat cultivar Aslı. In the experiment, the effect of sowing density and location on grain yield and yield components was found significant. In addition, sowing density × location interaction was found to be statistically significant in terms of grain yield. Grain yield was found between 693.2-849.7 kg/da, while spike length was ranged between 8.3-9.5 cm. However, number of spikelets per spike was in the range of 17.4-19.7, while number of grains per spike was 35.2-44.1 and grain weight per spike was 1.43-1.75 g. Among the locations, the highest grain yield was determined at Edirne location. In terms of grain yield, the most appropriate sowing density was determined as 400 seeds/m2 rate.
