The subject of this study is a three-year study (carried out during 2007, 2008 and 2009) of the morphological characteristics variability in three genotypes NS-Džin (Forage Sorghum), Zora (Sudan grass) and Siloking (interspecies hybrid) depending on the amount of nitrogen used for plant nutrition. For the height and mass analysis of fresh stems and leaves as well as leaf mass and leaf portion in the total biomass, samples were taken from the first swath when the effect of the used nitrogen amounts was the greatest. The results have shown that there are significant variations in the tested properties between the genotypes. The Siloking genotype had the highest total biomass during all three years. The largest leaf mass was found in the NS-Džin genotype, while the Zora genotype had the highest leaf portion in the three-year average. The effect of nitrogen use depended on the weather conditions, as well as the layout of the rainfall, so that the optimal quantity was 105 kg ha-1 during the... first and the second year, and 150 kg ha -1 during the third year.
Predmet ove studije su trogodišnja istraživanja (2007, 2008. i 2009) 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. Za analize visine i mase svežih stabala, mase listova i udela listova u ukupnoj biomasi uzimani su uzorci iz prvog otkosa kada je i efekat upotrebljenih količina azota bio najveći. Rezultati su pokazali da između genotipova postoje značajna variranja u ispitivanim osobinama. Genotip Siloking je u sve tri godine dao najveću ukupnu biomasu. Najveća masa listova bila je u genotipa NS Džin, dok je u genotipa Zora udeo lisne mase bio najveći u trogodišnjem proseku. Efekat upotrebljenog azota zavisio je od vremenskih uslova, odnosno od rasporeda padavina, tako da su u prvoj i drugoj godini optimalne količine bile 105 kg ha-1, a trećoj 150 kg ha -1.
