Topra ğa deği şik miktarlarda uygulanan azotlu ve fosforlu gübreler ile azotlu ve fosforlu gübreler aras ı ndaki interaksiyon ı spanak bitkisinin N, P, K, Ca, Mg, Fe, Cu, Zn ve Mn içerikleri üzerine istatistiki yönden %1 düzeyinde önemli etki yapmışt ı r. Toprağa artan miktarlarda uygulanan azotlu ve fosforlu gübrelerle ı spanak bitkisinin Ca, Fe, Cu, Zn ve Mn içerikleri azalmışt ı r. Artan azotlu gübre uygulamalar ı nda bitkide N, Mg içerikleri artarken artan fosforlu gübre uygulamalar ı nda P içeriği artm ışt ı r. Elde edilen veriler literatürde ı spanak bitkisi için verilen s ı n ı r değerlerle karşı laşt ı r ı ld ığı nda azotlu ve fosforlu gübre uygulamalar ı n ı n belirli i şlemlerinde N, P ve Ca içeriklerinin verilen s ı n ı r değerlerin alt ı nda olduğu belirlenmiştir.
The effect of increasing applications of nitrogenous and phosphorous fertilizers into soil and interactions between nitrogenous and phosphorous fertilizers on the N, P, K, Ca, Mg, Fe, Cu, Zn and Mn contents in spinach plant were found to be statistically significant at 1% level. Ca, Fe, Cu, Zn an Mn contents of spinach plant were decreased by increasing applications of nitrogenous and phosphorous fertilizers. N and Mg contents of plant were increased by increasing application of nitrogenous fertilizer, while P, content was increased by increasing applications phosphorous fertilizer. It was determined that N, P, and Ca contents of spinach plant growing in certain nitrogen and phosphour treatments were found to be below of the critical concentrations as the obtained data compared with literature for spinach plant.
