The paper examines the yield components and biomass yield of forage sorghum (NS Dzin) and Sudan grass (Srem) on pseudogley soil. As pseudogley is characterized by very poor physical and chemical properties, biomass yield was reported to be rather uniform in forage sorghum (45.8 t/ha green forage or 8.4 t/ha dry matter) and Sudan grass (47.9 t/ha green forage or 9.6 t/ha dry matter) over a two-year period. Leaf dry matter content was significantly negatively correlated with forage yield as well as with other yield components. More intensive exploitation, i.e. a fewer number of days between the previous and the following cutting induced an increase in leaf dry matter content and a simultaneous decrease in dry matter yield. Given the fact that plant ageing results in a considerable increase in crude cellulose content, it is necessary to identify and optimum exploitation stage in terms of biomass yield and quality.
