The effect of different rates of nitrogen fertilization (K— T1— N0; T2— N3; T3 — N5; Т4 — N7) during two-cut harvesting of winter forage pea was studied. It was found that the highest yields of dry matter and crude protein in double harvest of winter pea production of green mass is obtained in fertilization rate N5 respectively 23.04% аnd 23.88% higher values than the control. When fertilizing with N5 during two-cut harvesting of winter pea for production of green mass (first growth) and grain (second growth) the total yield of crude protein increased by 70.65%, as compared to the control harvesting only once for grain.
