In order to investigate the effect of seed amount consumption on the yield of dryland wheat cultivars, an experiment was conducted based on completely randomized block design in 3 replications in a private farm in Hesar Valiasr (AJ) village of Avaj city in the crop year of 1402-1401. The experimental factors included the amount of seed at the levels: 90, 120 and 150 kg/ha cultivars in 3 levels: Azar-2, Hashtroud and Sadra. To investigate the agricultural traits at harvesting time, eight plants were randomly selected from each plot. The results of the study showed that the amount of seed consumption had a significant effect on the traits, number of spikes per plant, number of seeds in the main spike, number of seeds in secondary spike, number of seeds per plant and 1000 grains weight. The mean comparison of simple effects show that the highest seed yield, harvest index was related to Azar 2 variety and the highest biological yield was related to Azar 2 and Hashtroud varieties. In the seed consumption rate treatments, the highest biological yield was gained in 150 kg/ha of seeds consumption, and the highest seed yield and harvest index was related to 120 kg/ha of seeds consumption. The mean comparison interaction effect of seed rate and variety demonstrated that application of 120 kg/ha in Azar-2 variety had the highest seed yield (1226 kg /ha) compared to 90 kg/ha seed application in Sadra variety (839.3 Kg/ha) as the lowest seed yield, (31.56% increase between 2 treatments). In all evaluated traits, Azar 2 showed superiority over other cultivars.
