Uticaj azotne prihrane na visinu izdanka engleskog ljulja (Lolium perenne L.)

Abstract

Engleski ljulj (Lolium perenne L.) reaguje porastom visine izdanka na prolećnu prihranu azotom. Pri maksimalnim količinama upotrebljenog azota (90 kg ha-1) ostvarene su najveće vrednosti posmatranog parametra u sve tri godine posmatranog ogleda (72,5 cm, 77,1 cm i 68 cm). Visina izdanka zabeležila je zavisnost u odnosu na vremenske prilike, tako da je treća godina (godina sa najvećom količinom padavina) uslovila ispiranje đubriva u niže slojeve zemljišta i najmanju prosečnu vrednost visine izdanka (68 cm).

Perennial ryegrass (Lolium perenne L.) reacts to spring feeding with nitrogen by increasing shoot height. With the maximum amount of nitrogen used (90 kg ha-1), the highest values of the observed parameter were achieved in all three years of the observed experiment (72.5 cm, 77.1 cm, and 68 cm). The height of the shoot also recorded a dependence related to the weather conditions, so that the third year (the year with the highest amount of precipitation) resulted in the leaching of fertilizers into the lower layers of the soil and the lowest average value of the height of the shoot (68 cm).
