Abstract
Wheat is one of the oldest agricultural crops and it is used for food by more than a half of the population on Earth. The economic importance of soft wheat and its contribution to human and livestock diets is undisputable. The aim of the current study was to determine the effect and interaction of factors such as variety and year on the yield and grain quality of common wheat varieties. With each subsequent harvest year, drought and an increase in the average daily temperature were observed, which proved to have an adverse effect on some indicators. The results showed that all four varieties have good productivity and quality during the observed harvest years and are suitable for growing in Southern Dobrudzha area, while at the same time the Sobel variety stood out. The results from the study imply that the test weight was influenced to a greater extent by weather conditions than by genotype.
