The area of the western Balkans is characterised with semi-arid climate, i.e. with hot summers and the unfavourable rainfall distribution. Growing maize silage has become unsafe, due to the appearance of long summer droughts. Alternative forage plants, such as fodder sorghum and Sudan grass, are more accustomed to drought conditions than maize and have recently became more interesting for growing under rainfed conditions. Their biomass quality does not lag much behind maize biomass quality. Under a more favourable water regime they regenerate well after mowing and in years of use they can give two to three swaths. The following genotypes were studied in the trial set up in the experimental filed of the Faculty of Agriculture in Belgrade during 2007, 2008 and 2009: NS Džin (fodder sorghum), Zora (Sudanese grass) and their interspecies hybrid Siloking. The plant nutrition consisted of the following amounts of nitrogen: 105, 150 and 180 kg ha-1. Ammonium nitrate was introduced into the so...il before sowing. In addition to these cultivars, a control group of plants was grown (60 kg N ha-1). The standard fodder sorghum growing practices were applied. Obtained results indicate that these genotypes have a high yield potential of the above-ground biomass. The biomass yield has significantly increased with additional amounts of nitrogen. The biomass yield was the highest during the year with the most favourable water regime. The growing amounts of nitrogen demonstrated a great influence on quality, as well as, on the nutritional value of the dry biomass. Nitrogen increased quality of the biomass twofold, through the increased percentile participation of leaves in total the above-ground biomass and greater synthesis of total proteins. .
