Comparison of different cool season cereal species and cultivars in terms of straw yield and quality

Abstract

This study was carried out in the year 2015-16 and 2016-17 growing season in order to determine and compare the yield, digestibility dry matter and relative feed value of straw obtained from cereals. In the study, which was carried out in three replications according to the randomized blocks experimental design; 3 bread wheat, 3 durum wheat, 3 triticale and 4 barley cultivars were used as plant material. The difference between cereal species in terms of plant height, biological yield, seed yield, straw yield and crude protein was statistically significant (P≤0.01). In terms of these features the highest results were obtained from triticale straw and the lowest values were obtained from barley and bread wheat straw. At the same time, the lowest crude protein ratio was obtained from triticale straw, where the best yield results were obtained. The difference between cereal species in terms of crude protein yield, ADF and NDF contens, digestibility dry matter and relative feed values were found to be statistically insignificant. As a result, it was determined that the species with the highest yield among the species was trikale. In terms of quality criteria, it was determined that only the crude protein content was statistically significant among the species and the lowest value was obtained from triticale and the highest value was obtained from bread wheat and barley in terms of this property.
