Stability of wheat yield on acid soil in the production of safe food

The investigation was carried out on the experimental field of Small Grains Research Center, Kragujevac. This paper presents the results of winter wheat varieties (Takovčanka, KG I00, KG 56S, Ana Morava and Lazarica). Grain yield, 1000 kernel weight and test weight in grain the investigated wheat cultivars was determined in a two-year field experiment. Average grain yield of wheat cultivars ranged from 3.0 II t/ha to 3. 774 t/ha. Grain yield differed significantly between years and the average of all cultivars was higher in 2006/07. By examining the physical properties of grain, Ana Morava was achieved the highest average yield in both growing seasons (3.049 t/ha; 4.499 t/ha). Average values of I000 grain weight of wheat varied in the range from 36.23 to 42.70 g.
