dc.description.abstractThis paper presents the variability of morphological traits of three genotypes: NS Džin (forage sorghum), Zora (Sudan grass) and Siloking (interspecies hybrid) depending on the nitrogen rates used for supplementary plant nutrition in 2007 and 2008. The following parameters were observed: plant height, leaf weight, stem weight, as well as, the proportion of leaves. The obtained results show significant variations in observed traits among genotypes. Nitrogen used in plant nutrition positively affected the increase in total biomass and leaf participation in it. This parameter is of interest to manufacturers of animal feed. Sorghums are plants with a good root system, strong suction power and plants that well adopt unused nitrogen salts that are used for crop nutrition. The increase in the effect of nitrogen rates is mainly affected by the precipitation sum and distribution. According to the two-year averages, Siloking genotype gave the highest total green biomass, leaf weight was greatest in the genotype NS Džin, while the leaf proportion of a genotype Zora was greatest. The effect of nitrogen depended on the weather conditions, or the precipitation distribution, so the optimum nitrogen rate in both years was 105 kg N ha-1. .en
dc.description.abstractU radu su proučavane varijabilnosti morfoloških osobina tri genotipa NS-džin (krmni sirak), zora (sudanska trava) i siloking (interspecijes hibrid) u zavisnosti od upotrebljenih količina azota za dopunsku ishranu biljaka tokom 2007. i 2008. godine. Ispitivani su sledeći parametri: visina biljaka, masa lista, masa stabla, kao i udeo listova u ukupnoj biomasi. Rezultati su pokazali da između genotipova postoje značajna variranja u ispitivanim svojstvima. Azot upotrebljen u ishrani biljaka je pozitivno uticao na povećanje ukupne biomase i učešća listova u njoj. Ovaj parametar je od interesa za proizvođače stočne hrane. Sirak je biljka snažnog korenovog sistema dobre usisne moći i koja dobro usvaja neiskorišćene azotne soli koje su upotrebljene za ishranu preduseva. Na povećanje efekta upotrebljenog azota veliki uticaj imaju količine i raspored padavina. U dvogodišnjem proseku genotip siloking je dao najveću ukupnu zelenu biomasu, najveća masa listova bila je kod genotipa NS džin, dok je kod genotipa zora udeo lisne mase bio najveći. Efekat upotrebljenog azota zavisio je od vremenskih uslova, odnosno od rasporeda padavina, tako da je u obe godine optimalna količina bila 105 kg ha-1. .sr
