The effect of nitrogen fertilization on dry matter yield of lucerne and legume-grass mixtures
Uticaj azotnog đubrenja na prinos suve materije lucerke i njenih smeša sa ježevicom i livadskim vijukom
Apstrakt
The aim of researh was to determine the effect of different amounts of nitrogen fertilizer on production and quality traits of pure lucerne crop and its mixtures with cocksfoot and meadow fescue. The research included pure lucerne crop (A1) and its mixtures with cocksfoot and meadow fescue in different combination (A2- 50% lucerne and 50% cocksfoot, A3- 50% lucerne, 25% cocksfoot and 25% meadow fescue, A4- 25% lucerne, 50% cocksfoot and 25% meadow fescue). Sowing was done in the fall with a raw spacing of 20 cm. Fertilization with nitrogen was done in early spring, with two treatment: 50 kg N ha-1, 100 kg N ha-1 and control without fertilization. Type of mixture had significant effect on dry matter yield, crude protein content, ADF, NDF and NFE, while amount of nitrogen fertilizer had effect on dry matter and crude protein yield.
Cilj ovih istrazivanja je da se ispita uticaj različitih količina azota iz mineralnih đubriva na proizvodne i kvalitativne osobine lucerke u monokulturi i u smeši sa jezevicom i livadskim vijukom. Istraživanja su obuhvatila cist usev lucerke (A1) i njene smeše sa jezevicom i livadskim vijukom u različitim kombinacijama (A2- 50% lucerke i 50% jezevice, A3- 50% lucerke, 25% jezevice i 25% livadskog vijuka, A4- 25% lucerke, 50% jezevice i 25% livadskog vijuka). Jesenja setva je obavljena u redove sa međurednim rastojanjem od 20 cm. Prihrana azotom je obavljena u proleće, sa kretanjem vegetacije u dva tretmana: 50 (B2) i 100 kg ha-1 (B3) i kontrolom bez primene azota (Bl). Vrsta smeše je imala statistički značajnog uticaja na prinos suve mase, sirovih proteina, ADF-a, NDF-a, BEM-a, dok je količina primenjenog azota imala uticaj na prinos suve materije i sirovih proteina.
