Abstract

Abstract: Effects of cultivar mixtures of wheat, crop density, amount of N-fertilizer,dose of triadimefon and pirimicarb on disease index of powdery mildew, number of Aphids on percent of plants and yields of wheat were evaluated respectively by using multifactor design.The results showed that cultivar mixtures had significant effects on the above three target functions.Effect of cultivar mixture on disease index of powdery mildew is more than that of crop density, and more than those of all other significant factors on both number of Aphids and yields of wheat.

Key words: Wheat, Cultivar mixtures, Powdery mildew, Aphids, Yield
