Hybrid sorrel during stooling stage has the best characteristics, such characteristics are worse at the budding stage due to increase in cellulose and decrease in protein. Content of ascorbic acid decreases by more than a half. Biomass increases significantly. The average daily increase at the stooling stage before blossoming makes 1.7 - 1.8 ton per day, starting from the third year amounts 2.9 - 3.0.

By its chemical content a green mass Rumex K - 1 is a valuable vegetable material in terms of high content of Vitamin C, organic iron, food fibres and zinc, which give all reasons to construct on its basis specialised food products, sanative diets and biologically active food additives.
