Özet

This study aimed to determine the effects of six nitrogen rates (0, 40, 80, 120, 160 and 200 kg ha(-1)) on forage yield and quality of crested wheatgrass (Agropyron cristatum L. Gaertn.). Dry matter (DM) yield, N, P, K, Ca, Mg, (K/Ca+Mg), NDF, ADF, TDN, DDM, DMI, RFV and NE(1) were determined. Nitrogen rates significantly affected most of the components determined in crested wheatgrass. Nitrogen applications increased DM yield, N, P and K contents but decreased Ca, Mg, tetany ratio, NDF and ADF. TDN, DDM, DMI, RFV and NE(1) increased by increasing N fertilization. The results showed that crested wheatgrass at the 160 kg ha(-1) nitrogen treatment achieved a higher forage yield and quality than other nitrogen doses.
