The effect of nitrogen fertilization on production and qualitative properties of sown grasslands in the system of sustainable production
Uticaj đubrenja azotom na proizvodne i kvalitativne osobine sejanih travnjaka u sistemu održive proizvodnje
Апстракт
Nitrogen fixation in grass-leguminous mixtures is not sufficient to satisfy the nitrogen requirements of plants, therefore it is necessary to compensate this deficiency by nitrogen from mineral fertilizers. Objective of this study is to present the effect of N application in grass-leguminous mixtures on their production and qualitative properties, i.e. to give an answer to the question if application of nitrogen fertilizers results in the increase or decrease of yield, quality and changes in the structural composition of the grassland. N from mineral fertilizers, especially considerable amounts of nitrogen, changes the structural composition of grasslands - the share of leguminous plants decreases and share of grasses increases. Yield of dry matter increases with added nitrogen fertilizers. The amounts of nitrogen fertilizer which exceed the requirements of plants reduce the economical justification of fertilization and sometimes can have even opposite effect. Nitrogen fertilization in...creases the content of crude proteins and protein yield, whereas other quality parameters decrease or remain unchanged. Too much nitrogen in crops leads to nitrate accumulation in plants which is undesirable quality parameter.

N iz mineralnih đubriva, naročito visoke količine azota, menjaju strukturni sastav travnjaka tako što smanjuju udeo leguminoza, a povećavaju udeo trava. Prinos suve materije se povećava dodavanjem azota đubrivima. Količine koje prevazilaze potrebe biljaka za azotom smanjuju ekonomsku opravdanost đubrenja i nekad mogu da imaju suprotan efekat.
