Abstract

The study was carried out to investigate the effect of liquid soil conditioner treatment on the quality traits of 3 bread wheat varieties in a randomized split-plot design with 3 replications during 2016 and 2018 years in the northwestern region of Turkey. It was subjected to four different soil conditioners (control (T1), (T2), (T3) and (T4)) at pre-sowing of seed. The differences among means of variety and treatment were significant indicate the soil conditioners applied to seeds had statistically significant effects for thousand grain weight (TGW), test weight (TW), wet gluten content (WGC), alveograph energy value (W) and grain protein content (GPC), was not significant for gluten index (GI) and Zeleny sedimentation value (ZSV). The highest means calculated in the Selimiye variety and the T3 treatment for Thousand grain weight and test weight. For wet gluten content, the highest values were obtained in the Flamura 85 variety and the T2 treatment. The Selimiye and Flamura 85 varieties and the T2 treatment were the best for protein content. As for the alveograph energy value, the Esperia variety and T1 treatment provided the highest means. In general, the mean of T4 treatment with the highest humic matter content was lower than that of the T3. The T2 treatment resulted in higher wet gluten content and protein content than the others, which is probably due to the nitrogen contained in it. In conclusion, considering the results, it was seen that T2 and T3 treatments had a more positive and significant effect on the quality characteristics of bread wheat than the control.
