This variety is distinguished by high seed productivity and resistance to lodging, ensuring reliable and efficient cultivation. It contains 17.6% protein and 27.4% fiber in dry matter, making it a valuable feed plant. Yield of dry matter in the fourth region averages 74.6 c/ha, with maximum yields reaching up to 231.2 c/ha. To enhance productivity and improve the quality of 'RASTOROPNY' clover, the use of Clever HX fertilizer is recommended. This fertilizer contains a significant amount of free amino acids, low molecular weight peptones, as well as vitamins, micro- and macroelements, which improve the organoleptic characteristics of the plant. Clever HX is applied as a concentrated suspension and suitable for foliar application, fertigation, or root soaking at all growth stages, including transplanting, flowering, and maturation. The use of Clever HX fertilizer positively affects the vegetative development of clover, ensuring full nutrient supply for normal plant function. It increases resistance to adverse environmental factors and promotes growth even on difficult soils, such as loam or sandy. Additionally, the fertilizer improves fruit development, helping them swell better and protecting against cracking and deformation, thereby increasing crop quality and yield.
