ПРЕПАРАТ РИБАВ-ЭКСТРА КАК ЭФФЕКТИВНЫЙ РЕГУЛЯТОР РОСТА И РАЗВИТИЯ РАСТЕНИЙ ГОРОХА

At present, a significant role is assigned to the solution of the state food problem, and it is one of the most important problems of the modern world. In this regard,  biologization of agriculture with the use of biological plant protection products from pests, a new generation of biological preparations that help stimulate plant growth processes occupies a special place, and results in an increase of the crops yield. Biological methods, or in general, biologization of agriculture in our country is not large-scale due to the main problems of productivity and quality of crops - low soil potential, high prices for fertilizers, the negative impact of pesticides used in production on plants and soil biota. The article presents the results of the study on the phytoprotective and growth-promoting effect of Ribav-Extra biological preparation on pre-sowing treatment of seed material of new varieties of Nord pea for food purposes and Orpela for fodder purposes. The studies have found the presence of a stimulating effect due to the treatment of pea seeds with Ribav-Extra, in the form of an increase in the length of sprouts and rootlets of seedlings up to 35% in the Nord variety and 50% in Orpela one. There is also an increase in the energy of germination of pea seeds – of the laboratory one by 10% and of the field one by 5-9 % of germination. It has been established that seed material processing with the Ribav-Extra biological preparation contributes to the effective acceleration of the growth processes of peas at the initial stages of development, thereby increasing their resistance to adverse environmental conditions. As a result of three-year studies, the positive effect of Ribav-Extra preparation on the grain yield of the studied pea varieties has been established up to 16% (Nord) and 19% (Orpela).
