ABSTRACT
The effect of variety, maturity and sowing density of pea in mixtures with spring wheat and Italian ryegrass grown for silage on dry matter yield, level of nutrients in green forage and chemical composition and quality of silage was studied. The average dry matter yield of the forage mixtures for the factors and vegetative seasons studied was 7.4 t ha-1. The participation of pea plants in mixtures before ensiling was from 31 to 45% and that of spring wheat and Italian ryegrass from 39 to 46% and from 13 to 23%, respectively. The dry matter in green forage from the mixtures averaged 250 g kg-1 and in silage 224 g kg-1. Rumen degradability of dry matter of the of silage during 2 to 48 h incubation ranged from 52 to 81%. No significant effect of pea variety and mixture sowing density on yield, dry matter and nutrients contents in green fodder and chemical composition of the silage (P ≥ 0.05) was found. A significant effect of pea maturity and year of growth of the forages on content of nutrients in the green forage and chemical composition of the silage was found (P ≤ 0.01).
