Results of ecological testing of varieties of narrow-leaved lupine in the conditions of the Kirov region

The article presents the results of ecological testing of varieties of narrow-leaved lupine in the conditions of the Kirov region. The material for the study is varieties of narrow-leaved lupin of the selection of the Lupin Research Institute of the branch of the Federal State Budgetary Scientific Research Center of Feed Production and Agroecology named after V.R. Williams: Siderat 46, Bryansk Fodder and Leningrad Research Institute of Agricultural Research of the A.G. Lorkh Federal State Budgetary Institution of Potato FITZ: Accord, Fedorovsky, Patron. The research was carried out on the basis of the Agrotechnopark of the Vyatka State Technical University in 2021-2022. The soils of the site are sod-medium podzolic, medium loamy, slightly acidic, of an average degree of availability of mobile phosphorus and exchangeable potassium. The years of research were different in terms of weather and climatic conditions. As a result, it was found that all the studied varieties of narrow-leaved lupine in the field are characterized by high germination and preservation of plants by the time of harvesting. This indicates that there are favorable conditions for the growth and development of this crop and indicates the possibility of obtaining high yields. In terms of grain yield, Siderat 46 and Bryansk fodder varieties significantly exceeded the control by 11.5 and 14.1%, respectively. Varieties Siderat 46 and Bryansk fodder have a higher stem, form an average of 5.0-6.3 pcs. of beans per plant, in which 4.2-4.5 pcs. of seeds develop in each. By the number of beans on the plant, it is also possible to note the Fedorovsky variety, whose plants are able to lay 83% more beans than the control. Thus, among the studied varieties of narrow-leaved lupine of the selection of the Lupine Research Institute of the branch of the FSBI "FNC of Feed Production and Agroecology named after V.R. Williams", the Leningrad Research Institute of Agricultural Research of the branch of the A.G. Lorch Potato FITZ in the conditions of the Kirov region, according to grain yield and the indicators that provide it, it is possible to distinguish the varieties Siderate 46 and Bryansk fodder. They may well serve to increase the biologization of agriculture and the goals of regenerative agriculture.
