The Rate of Productive Tillers per Plant of Winter Wheat (Triticum aestivum L.) Cultivars under Different Sowing Densities

Abstract

The aim of this two‒year research was to determine the rate of productive tillers per plant of different winter wheat cultivars under different sowing densities in the agroecological conditions of Banja Luka. NS 40S, Prima and Nova Bosanka wheat cultivars were sown at eight different sowing densities: 384, 424, 451, 504, 544, 584, 588 and 604 seeds m-2. The experiment was set up in the open field, and each wheat cultivar was sown at different sowing density in four replications. Statistical analysis was performed using factorial analysis of variance 2×8×3 while significant differences between treatments were tested by LSD test. The highest average rate of productive tillers per plant was achieved for the winter wheat cultivar NS 40S (2.29). The highest average rate of productive tillers per plant was achieved at sowing density of 384 seeds m-2 and the lowest at sowing density of 588 seeds m-2.
