Abstract:

This study was carried out in the 2019-2020 and 2020-2021 wheat growing seasons in order to determine the yield and yield characteristics of 25 durum wheat varieties in rainfed and irrigated conditions in Tokat-Zile location. Experiments were set up in a randomized block split plot design with three replications in rainfed and irrigated conditions. In the study, significant differences were found between cultivars in all traits examined in line with the combined environments (year, rainfed-irrigated) averages. The average heading period of the cultivars in rainfed and irrigated conditions was 153.8 and 155.1 days, maturation period was 186.0 and 188.7 days, plant height 66.2 and 70.7 cm, number of grains per spike 26.6 and 29.7, spike length was 5.9 and 6.4 cm, number of spikes per square meter was 245.4 and 300.6 number, single spike yield 1.26 and 1.48 g, thousand grain weight 41.5 and 43.4 g, test weight 80.4 and 81.0 kg, grain yield 252.8 and 315.9 kg/da. In terms of average values, the values obtained in irrigated conditions were found to be higher than rainfed conditions. According to the results of the combined environments, grain yields of the cultivars varied between 220.2-351.3 kg/da. In the research, Soylu cultivars came to the forefront in spike length and plant height, Şahinbey and Ankara 98 varieties in thousand grain weight, Sarıçanak 98 test weight, Eminbey, Altın 40/98, Mirzabey and Ankara 98 varieties in grain yield. It has been determined that Eminbey, Altın 40/98 and Ankara 98 varieties with high grain yield and other desired characteristics can be grown successfully in Tokat Zile location.
