The aim of this research is to study two important factors in wheat production (Triticum sp.) - sowing time and variety, specifically their influence on wheat yield and yield components: the number of grains per spike, grain weight per spike, 1,000-grain weight, and the hectoliter weight. The influence of sowing time and variety were determined based on the obtained data, which indicated the extent to which the significance of these factors manifest on certain components and wheat yield. The optimal sowing date is October 5th-25th. The variety itself cannot give a high yield without the application of all agrotechnical measures, to which we strive for primarily due to the high wheat importance. The experiment set up by the split-plot method in three replications examined three wheat varieties: Gabrio, Rapsodija and Basmati sown in two sowing dates: October 29th and November 25th. The results showed that all yield components (the number of grains per spike, the grain weight per spike, the 1,000 - grain weight, and the hectoliter weight) had the highest values in Rapsodija variety and were more dependent on the variety than to sowing time. The influence of the variety on the hectoliter mass was at a significant level. Wheat yield depended more on sowing time, and the influence of sowing time, variety, and interaction of these two factors on yield were statistically significant. The highest yield was registered in Gabrio variety (8.87 t ha-1), while the average yield achieved by this micro experiment was 8.46 t ha-1.
