Potential of productivity of perennial grasses in one-way and mixed sowings on sewed peat soils of Western Polissia

Abstract

The purpose. To determine potential of productivity of perennial cereal grasses in one-way and mixed grass stands, optimum species composition of grass mixtures, regime of fertilizing and mowing grass stand at growing grasses on sewed peat soils of Western Polissia. Methods. Field, laboratory, dispersion analysis. Results. Outcomes of long-term probes on influence of fertilizing and regime of mowing upon productivity of main perennial grasses and their grass mixtures on sewed soils of Western Polissia are brought. Conclusions. It is determined that the most fruitful among perennial cereal grasses on sewed peat soils are the following species: Phalaris arundinacea, Brōmus inērmis, Phléum, Alopecúrus and Beckmánnia. In one-way grass stands these crops at long use ensure average productivity of hay more than 10-12 t/hectare. Among grass mixtures of long-term use for hay the most productive one is the mixture of Phléum, Festuca pratensis or Dáctylis glomeráta at obligatory presence of Brōmus inērmis.
