Abstract

Bu araşt ı rma Van ekolojik şartları nda dekara O, 4, 8 ve 12 kg azot düzeylerinin farkl ı vejetasyon d'inemlerinde ve bitkinin farkl ı k ı s ı mlar ı nda besin elementi içeri ğ ine etkisini belirlemek amac ı yla yürütülmüştür. Ara şt ı rma sonuçları na göre, artan oranlarda verilen azotlu gübre yapra ğı n azot ve potasyum içeriğ ini, tane, sap ve tablen ı n azot içeriğ i ile sap ı n potasyum içeri ğ ini ad ı nrken, yaprağ in fosfor, demir, mangan içeriklerinin, tane, Sap ve tablenin"fosfor, kalsiyum, magnezyum ile çinko içeriklerinin azalmas ı na neden olmuştur. Yapra ğı n azot, fosfor, mangan içerikleri, tane, sap ve tablan ı n azot içerikleriyle tane ve sap ı n kalsiyum içerikleri farkl ı azot formlar ı ndan -etkilenmiştir. Besin elementi içeri ğ ine bitki çeşitlerinin etkisi önemli bulunmu ştur.

Effects of Different Nitrogenous Fertilizer Doses and Forms on Nutrient Content in Sunflower

Abstract

This study was carried out to determine the effect of different forms of nitrogen sources ammonium sulfate ammonium nitrate, urea at O, 4, 8 and 12 kg /da levels on sunflowers nutrient contents at different stages of veget don and parts of plant in Van ecological conditions. The results of experiment showed that nitrogen content of leaf, eed, stem and head, and potassium content of leaf and stem increased with increased nitrogen doses, On the other nand, phosphorus, iron, manganese contents of leaf, and phosphorus, calcium, magnesium, zinc contents of seed, sterr and head decreased with nitrogen doses. Nitrogen, phosphorus, calcium, manganese contents of leaf, and nitro jen contents of seed and stem were affected differently with the nitrogen sources. Nutrient contents of sunflower werr affected by sunflower cultivars.
