Impact of year yield and grain quality of winter wheat

Abstract

This paper presents the results of winter wheat varieties (Vizija and Kruna). The cultivars were grown in the experimental field of the Center for Small Grains, Kragujevac, during two growing seasons. By examining the physical properties of grain, variety Kruna achieved the highest grain yield (5.150 t/ha), while a slightly higher 1000 grain weight (41.78 g) and test weight (75.35 kg/hl) was variety Vizija, during the two-year study period. Data analysis showed significant dependence between the of 1000 grain weight and years of research. The difference found between the significance of the impact of variety on grain quality of wheat cultivar, was highly significant for test weight. The differences in significance from the point of interaction year x cultivar on the average value of grain yield were statistically highly significant, while for test weight and 1000-grain weight were not significant. Cultivars Vizija and the Kruna have conducted surveys have shown a high degree of adaptability conditions of production of wheat and had a satisfactory yield in the examined vegetation seasons.

U radu su prikazani rezultati ispitivanja ozimih sorti pšenice (Vizija i Kruna). Sorte su gajene na oglednom polju Centra za strna zita, Kragujevac, tokom dve vegetacione sezone. Ispitivanjem fizičkih osobina zrna, sorta Kruna je ostvarila najveći prinos zrna (5,150 t/ha), dok je nešto veću masu 1000 zrna (41,777 g) i hektolitarsku masu (75,350 kg/hl) imala sorta Vizija, tokom dvogodišnjeg perioda ispitivanja. Analizom dobijenih podataka utvrđena je značajna zavisnost između mase 1000 zrna i godina istrazivanja. Utvrđena razlika značajnosti između uticaja sorte na kvalitet zrna kod ispitivanih sorti pšenice, bila je vrlo visoko značajna za hektolitarsku masu. Ustanovljene razlike značajnosti sa stanovišta interakcije godina x sorta na prosečne vrednosti prinosa zrna, bile su statistički vrlo značajne, dok za hektolitarsku masu i masu 1000 zrna nisu bile signifikantne. Sorte Vizija i Kruna su u sprovedenim ispitivanjima pokazale visok stepen adaptabilnosti uslovima proizvodnje pšenice i imale su zadovoljavajući prinos u ispitivanim vegetacionim sezonama.
