Influence of Khorasan wheat (Triticum turgidum Turanicum) sowing rate on seed yield and quality

U strukturi sjetve strnih žitarica Khorasan pšenica u Hrvatskoj zauzima najmanje površine. Globalne klimatske promjene ukazuju na potrebu uzgoja starih vrsta i odabira norme sjetve u svrhu ostvarivanja visokih prinosa dobre kakvoće. Tijekom 2020. godine provedena su poljska ispitivanja o visini prinosa i kakvoći sjemena s različitim varijantama norme sjetve. Korištene su sljedeće varijante norme sjetve 150 kg/ha, 180 kg/ha i 220 kg/ha. Pokus je postavljen po slučajnom blok rasporedu u HAPIH - Centru za sjemenarstvo i rasadničarstvo u Osijeku (N 45°31´, E 18°40´) s tri varijante norme sjetve u tri repeticije. Prema dobivenim rezultatima analize varijance najveći prinos i hektolitarsku masu ostvarila je varijanta 3 (220 kg/ha), te su utvrđene statistički opravdane razlike. Između varijanti norme sjetve na sadržaj proteina nisu utvrđene statistički značajne razlike (n.s.). Cilj provedenog ispitivanja bio je utvrditi utjecaj najpovoljnije norme sjetve na prinos i kakvoću sjemena khorasan pšenice.In the structure of sowing small cereals, khorasan wheat occupies the smallest area in Croatia. Global climate change indicates the need of breeding old species and select a sowing rate in order to achieve high yields of good quality. During 2020, field study was conducted on yield and quality of seed with different variants of the sowing rate. The following variants of sowing rate were used 150 kg/ha, 180 kg/ha and 220 kg/ha. The experiment was based on a random block at the CAAF - Center for Seed and Seedlings in Osijek (N 45°31´, E 18°40´) with three variants of sowing rate in two repetitions. According to the obtained results of the variance analysis for different variants of sowing rate the highest yield (kg/ha) and hectolitre mass (kg/hl) was achieved by the variant 3 (220 kg/ha) and there are statistically justified differences. No statistically significant differences (n.s.) were found between the variants of sowing rate for the protein content. The aim of the study was to determine the impact of the most favorable sowing rate on seed yield and quality for khorasan wheat
