A positive effect of the fertilization system on the productivity of grass mixtures of different maturity was established: when using the complex mineral fertilizer Nitrofoska-M, the yield of green mass increased by 25.6–34.3% or by 24.7–34.1% of dry mass; complex mineral fertilizer Polifoska 8 - by 48.8–51.9% and 46.3–50.6%; of liquid mineral fertilizer Cropmax by 11.1–12.4% and 11.8–12.2%, respectively. The most productive (50.9–54.7 t/ha of green or 12.0–12.8 t/ha of dry mass) were grass mixes, which were fed in early spring and after each mowing with the complex mineral fertilizer Polifoska 8. The economic effect is 15950– UAH 17,903 conditionally net profit, cost of green fodder 472–486 UAH/ha, KEE 11.8–12.0, production profitability 64.4–69.2%. Among grass stands of varying maturity, the highest collection of fodder units (10.54 t/ha) and digestible protein (1.39 t/ha) was found in the late-ripening grass mixture when fed with the complex mineral fertilizer Polifoska 8, which is 1.98–2.87 t/ha of green mass (0.45–0.55 t/ha dry) is more compared to other options and, accordingly, by 3.61 t/ha and 0.43 t/ha to the control. Provision of 1 cor. unit digestible protein in the green fodder of perennial grass mixtures of different ripening is 131.8 g. The effective action of the fertilization system in perennial grass mixtures based on different methods of their creation is determined.With the solid sowing method, fertilizing with the complex mineral fertilizer Polyfoska 8 (background – Helprost) increased the yield by 27.8–30.4% of green or 28.9–34.0% of dry mass, and with strip sowing – by 21.5–26 .4% or 20.0–26.7%, respectively, compared to the control variants. When fertilizing with liquid mineral fertilizer Cropmax (background - Product Description popup.authors Markina Olga V Ratoshnyuk Ivan Yu Ratoshnyuk Victor I popup.nrat_date 2024-01-10 Close
