Specificities of growing seed wheat in agroecological conditions of Bosnia and Herzegovina

Abstract

Winter wheat is the most important winter crop in Bosnia and Herzegovina as well as in the region. The yield of winter wheat varies depending on the variety and agroecological growing conditions. For sowing wheat, the sowing rate is 250-300 kg ha^-1. About 50,000 ha are sown annually in Bosnia and Herzegovina, which requires about 15,000 tons of seeds. From this quantity, about 10% of needs are met from own production, and the rest of the seeds are imported. This paper analyzes the production of seed wheat at one of the largest domestic producers of wheat seeds. The paper presents data on seed production in two years, at three locations with four genotypes. The obtained results show that superior yields can be achieved using appropriate agricultural techniques and an assortment with good genetic predispositions. Due to the specificity of climatic and edaphic factors, good results are also achieved when growing specific genotypes with increased protein and gluten content. Statistically highly significant (p˂0.01) positive correlations were found between protein content and gluten content (0.98**). Highly significant correlations were found between hectolith mass and protein content (0.60**) and gluten (0.56**). The goal of the work is to increase the domestic production of seed wheat, as well as to carry out rezoning of the sowing of the appropriate assortment based on the analysis.
