Sorghum and fodder broad beans were sowed after harvest as pure crops and in combined sowing. Planned density of sorghum and fodder broad beans in pure crops was 800 thousand plants per hectare. Forming of joint/combined crop was carried out by reducing both species by 1/2 compared to pure crop. Sowing in joint crop was carried out in same and consecutive rows. Crop was grown under conditions with irrigation. Sorghum had higher yield (5535 kg/ha) compared to fodder broad beans (4918 kg/ha). The highest yield was gained from mixture of sorghum and fodder broad beans (6027 kg/ha), and this was considererably higher yield compared to sorghum yield and extremely considerably higher than yield of fodder broad beans. Higher yield of mixtures is consequence of higher yield of fodder broad beans compared to expected yield. Fodder broad beans had higher content of crude proteins, cellulose and fat which influenced that mixtures also had higher content of same matters compared to sorghum. All crops had higher net energy value in production of milk compared to production of meat. The highest net energy value was realized by sorghum, whereas mixtures realized higher net energy values per unit of surface. By combining crops higher yield per unit of surface and better balance of nutritive matters is achieved which offers possibility of greater meat and milk production per unit of surface.
