Abstract :This research was conducted to investigate effects of different zinc, phosphorus and nitrogen doses on yield and yield components of \\\"Gerek 79\\\" wheat variety under Konya ecological conditions. Zinc, phosphorus and nitrogen application increased significantly the grain yield of wheat. The grain yield was increased by zinc application up to 119%. The increase was higher than the other elements. Zinc x phosphorus, zinc x nitrogen and phosphorus x nitrogen interactions affected significantly on grain yield (P< 0.01). The effect of phosphorus and nitrogen doses depended on largely zinc application. The highest grain yield was obtained from 5 kg P205/da+ 10 kg N/da + Zn applied combinatons. Among the yield components, the ear number per square was most effected positively by zinc application.
