The optimal nitrogen input is very important factor to achieve
high crop yields at lower costs of production on farms. The aim of this research
was to estimate the effects of different nitrogen levels (0, 60, 120 and 180 kg ha-1)
on forage yield and quality green mass in two maize hybrids ZP 666 and NS 6030.
Field experiment was conducted on dry land farming at the Institute for Animal
Husbandry Belgrade-Zemun in 2013. The tested hybrid NS 6030 had significantly
higher ear height (EH), number of leaves (NL), buffering capacity of green mass
(BC) and water soluble carbohydrates (WSC) and significantly lower dry matter
content (DM) and crude protein content (CP) than hybrid ZP 666. Nitrogen levels
have significantly effect on plant height (PH), NL, forage yield (FY), rain use
efficiency (RUE), N use efficiency (NUE), CP, BC and WSC. PH and RUE did
not differ between treatments fertilized with 60, 120 and 180 kg N ha-1. Maximum
NL and FY observed at 120 kg N ha-1, CP at 180 kg... N ha-1, BC at control and NUE
and WSC at 60 kg N ha-1. NUE was significantly decreased with increased N rate
from 60 to 180 kg ha-1. NUE significantly depends on the availability of water, as
indicated by the correlation coefficient between these parameters. Studied hybrids
are suitable for ensiling. N rate of 120 kg N ha-1 can be recommended for growing
studied hybrids in order to achieve high yields and quality of forage.
