ACTION OF GUMITON ON THE SUSCEPTIBILITY TO ANTHRACNOSIS AND PRODUCTIVITY OF WHITE LUPIN PLANTS IN CONDITIONS OF BRYANSK REGION

Abstract

 Gray forest soils of the Non-Chernozem zone of Russia are characterized by a low level of natural fertility. The use of modern mineral and organic fertilizers can increase the content of nutrients available for plants. In modern technologies for cultivating crops, methods of processing planting (sowing material), as well as non-root treatment of vegetating plants with organomineral complexes are widely used. The biologically active substances included in their composition affect physiological processes, increase resistance to the effects of phytopathogenic microflora. The purpose of the research is to study the effect of the agrochemicals "Complex of biologically active organic-mineral Gumiton" on the productivity and damage of white lupine plants by anthracnose in the Bryansk region. The studies were conducted on gray forest lightly loamy soil under production conditions. Sheet treatment of white lupine was carried out during the Gumiton stem phase at a dose of 0.5, 1.0 and 1.5 l/ha. Due to the additional intake of moisture with a slight excess of air temperature, an activation of the damage of lupine beans by anthracnose was observed. Based on the presented efficacy data of the used agrochemicals, the resistance of plants to this disease increased. Minimal damage to lupine beans was noted with the use of the drug at a dose of 1.5 l/ha. The maximum efficacy under this option was noted in 2019: the damage rate decreased by 8.7% compared to the control. It was found that when treating plants with Gumiton at a dose of 1.5 l/ha, the indicators of the lupine crop structure improved: the number of beans increased by 30.3%, (2019); the number of grains and the mass of grains from the plant in 2021 increased by 29.4% and 27.5%. In 2020 and 2021, at the maximum dose of the drug, grain yield increased by 13.0% and 11.0%. In 2020 and 2021, at the maximum dose of the drug, grain yield increased by 0.28 t/ha. The research results indicate that in the production conditions of the Non-Black Earth Zone of Russia, the use of the agrochemicals "Biologically Active Organic-Mineral Gumiton Complex" is an effective technological technique for cultivating legumes. Due to its widespread use, it is possible to increase the feed base of the enterprise.
