The invention relates to biologically active compounds, especially to some water soluble copolymers with properties of plant growth regulators. The copolymers, according to the invention, are composed of structural units of N-vinylpyrrolidone and potassium or ammonium methacrylate in molar ratio of 84: 16, with properties of plant growth regulators. The result of the invention consists in that the claimed copolymers ensure the increase of the agricultural harvest by 7… 10% compared to the nearest solution. |
