Abstract :This study was conducted to investigate the efficiency of diammonium phosphate insert ignore into journalissuearticles values(DAP); and triple superphosphate insert ignore into journalissuearticles values(TSP); as phosphorus insert ignore into journalissuearticles values(P); sources and the effect of fertilizer application methods on the grain yield, yield components and other characteristics of winter wheat. The research was conducted in the ecological conditions of Tokat-Kazova during the 1990-1991 and 1991-1992 growing seasons. Bezostaja-I and Kirkpinar-79 cultivars were used as the plant materials. DAP and TSP fertilizers were applied according to four different methods, i. e., broadcasting, with seed, application 5 cm to the right and left of the seed and 5 cm below the seed. The effects of DAP and TSP on the characteristics examined were not significant. Effects of the application methods on emergence period, the number of plants/m 2 and grain yield were found to be significant in the first year, whereas all characteristics were affected significantly in the second year. The maximum grain yield was obtained from application 5 cm below the seed in both years.
