The research results of the production traits of forage Sorghum genotypes, Sudan grass and their interspecies hybrid during intensified nitrogen nutrition showed that the utilization of this element depends on the water levels. Increased amounts of nitrogen in drought condition have not affected the vegetative growth of plants. When the water level conditions were favourable, the optimal biomass growth was obtained by using 150 kg/ha of nitrogen. Very good productive characteristics of the interspecies hybrid show that the genotype obtained through selection can be a suitable fodder crop replacement for the currently grown species of the Sorghum genus, as well as for maize.
