TAILIEUCHUNG - Effect of phosphorus fertilizers and application methods on the yield of wheat grown under dryland conditions

This study was conducted to investigate the efficiency of diammonium phosphate (DAP) and triple superphosphate (TSP) as phosphorus (P) sources and the effect of fertilizer application methods on the grain yield, yield components and other characteristics of winter wheat. | Tr. J. of Agriculture and Forestry 23 (1999) 393-399 © TÜBİTAK Effect of Phosphorus Fertilizers and Application Methods on the Yield of Wheat Grown Under Dryland Conditions* Sabri GÖKMEN, Özer SENCAR University of Gaziosmanpaşa, Agricultural Faculty, Tokat–TURKEY Received: Abstract: This study was conducted to investigate the efficiency of diammonium phosphate (DAP) and triple superphosphate (TSP) as phosphorus (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 Kırkpınar–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/m2 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. Fosforlu Gübre ve Uygulama Yöntemlerinin Kurak Şartlarda Buğday Verimine Etkisi Özet: Bu çalışma, fosfor kaynağı olarak kullanılan DAP ve TSP ile bunların uygulanış şeklinin kışlık buğdayda tane verimi ve verim komponentleri ile bazı özelliklere etkisini araştırmak amacıyla yapılmıştır. Araştırma 1990–91 ve 1991–92 vejetasyon döneminde Tokat–Kazova koşullarında yürütülmüştür. Çalışmada bitki materyali olarak Bezostaja–I ve Kırkpınar–79 çeşitleri kullanılmıştır. DAP ve TSP; serpme, tohumla birlikte, tohumun 5 cm sağına ve soluna ve 5 cm altına olmak üzere dört farklı şekilde uygulanmıştır. Araştırmada incelenen özelliklere DAP ve TSP’nin etkisi önemsiz
