Abstract
Effect of Various Phosphorus Fertilizers on Yield of Wheat Crop
A pot experiment was carried out to see the effect of various phosphorus fertilizers which are still used in Tokat region on yield and N-P-K content of wheat crop. Wheat variety 39 was used as test plant. 50, 100 and 150 kg P205/ha were applied at as süper phosphorus (20-20-0), DAP and TSP fertilizers. Since süper phosphorus contained about 1 % zinc sulphate, therefore 100 kg P20i /ha as DAP +25 kg/ha zinc sulphate and 100 kg P2Oj/ha as TSP +25 kg/ha zinc sulphate treatments were added to the trial for comparision.
The results showed that phosphorus fertilizers used at 3 levels have significantly increased the dry matter yield and grain yield of wheat crop. A significant increase only in N content of straw, N and K content of wheat grain and NPK uptake of wheat straw and only K uptake of wheat grain was observed in this study.
