THE STABILITY PROPERTIES OF WHEAT PRODUCTION ON ACID SOIL

The investigation was carried out on the experimental field of Center for Small Grains, Kragujevac. This paper presents the results of winter wheat varieties (Takovcanka, KG 100, 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 2.151 t/ha to 4.206 t/ha. Grain yield differed significantly between years and the average of all cultivars was higher in 2006/07. compared to 2005/06. The study of physical properties of grain, cultivar KG 56S had the largest average grain yield in 2005/06th year (2.455 t/ha), while in the second year the highest yield was cultivar Ana Morava (4.206 t/ha). Average values of 1000 grain weight of wheat cultivars varied in the range from 36.26 to 42.58 g. The difference found between the significance of the impact on the quality of grain and test weight of wheat cultivars were significant for grain yield. Analysis of the data revealed that the genotype is very significant impact on the 1000 grain weight.
