The investigation have proved that mean hay yields from meadows irrigated with waste waters and intensively fertilized amounted to 12-14 t of dry matter from hectare. Irrigation resulted in an average increase of the yield by 3-5 t and fertilization - by further 3-4 t from hectare. Both irrigation and fertilization led to a reduction of dry matter content in green fodder, worsening simultaneously its silage-forming properties. So it would be purposeful to dry additionally such green fodder before ensiling. In dried fodder a slight decrease of digestibility coefficients of nitrogen-free extracts and organic matter at simultaneous increase of protein digestibility coefficient was observed. Irrigation resulted in an inconsiderable decrease of digestibility coefficients in relation to dried fodder from non-irrigated meadows
