“…Studies with beans plants were carried out under the conditions of a field experiment at the Federal State Budgetary Scientific Institution of the All-Russian Research Institute of leguminous and cereal crops (Oryol region). The conditions for the experiment were described earlier (Pavlyuchik et al, 2019;Matvienko et al, 2022). Seeds of bean plants of both varieties were soaked for 3 h in a solution of Epin-extra at a concentration of 10 -6 M, then dried, and treated with Rizotorfin before sowing.…”

In a vegetation experiment with soybean plants of the Svapa and Mageva varieties and in a field experiment with bean plants of the Geliada and Shokoladnitsa varieties, we studied the effect of pre-sowing treatment of the seeds of these plants with Rizotorfin and Epin-extra on the nitrogenase activity of the nodules of these plants and their ultrastructure. Analysis of the ultrastructure of the nodule tissue of beans and soybeans was carried out in the flowering phase. It was found that the highest indices of the mass and number of nodules and the activity of nitrogenase in them were found in bean plants of the Heliada cultivar when the seeds were treated with Epin-extra against the background of inoculation with Rizotorfin, where the largest area of symbiosomes, volutin and their number was noted in the nodules. Beans of the Shokoladnitsa variety showed the protective effect of Rizotorfin. In the nodules of soybean plants of the Svapa variety, the seeds of which were treated with Epin-extra against the background of inoculation with Rizotorfin, the presence of a large number of symbiosomes, bacteroids, volutin inclusions with a larger area and a minimum number of inclusions of poly-β-hydroxybutyric acid (PHB) was noted, and the highest indicators of symbiotic activity. Soybean plants of the Mageva variety showed the protective effect of Rizotorfin. The efficiency of the symbiotic system was determined by the number and weight of nodules and the activity of the nitrogenase enzyme.

“…The cocksfoot (Dactylis glomerata L.) can become such a crop. As a valuable plant, it is cultivated on peat soils in its pure form and in the composition of grass mixtures, it is used to create highly productive hayfields and pastures, for a raw material conveyor, subject to the appropriate agrotechnical methods, it is kept in the herbage for 8-10 years, is durable, has a high aftermath [3][4]. Such properties of the cocksfoot are very important, such as drought resistance, stable yields over the years, high responsiveness to fertilizers, especially nitrogen fertilizers, wide adaptability to environmental conditions, rapid regrowth after mowing and grazing, high nutritional value of vegetative mass [5][6].…”

Perennial grasses play an important role in increasing land productivity and increasing the production of high-protein fodder. They are grown in field and fodder crop rotations, in cultivated hayfields for green fodder, hay, haylage, grass cutting and grass meal. In the fodder balance, they account for almost half of the total requirement of farm animals for plant fodder. The cocksfoot (Dactylis glomerata L.) is just such a perennial cereal crop that can become the basis for creating a solid forage base. Creation of a new variety, high-yielding, with good quality forage mass, high adaptability to biotic and abiotic environmental factors, is a solution to the urgent problem of strengthening the branch of forage production. The studies were carried out in the Komi Republic (Russia, Syktyvkar) in the period from 2016 to 2018. in order to determine the parameters of adaptability and yield of green mass of collection samples and promising populations of cocksfoot combined with the subsequent selection of the most valuable of them for further breeding work. We studied samples of various ecological and geographical origin obtained from the world collection of the All-Russian Institute of Plant Genetic Resources named after N.I. Vavilov - VIR (Russia, St. Petersburg), geographically belonging to the Barents Euro-Arctic region: eight from Russia, including five from the Republic Komi (42733, 42734, 42736, 43024, 45945) and three from the Arkhangelsk region (44342, 36684, 44343), two from Norway (41826, 44021) and one from Finland (47268). According to a set of economically valuable parameters, samples 42733, 45945, 41826 were identified with a yield of green mass on average for two mows of 220-237 c / ha. Varieties Dvina and Naka with values of adaptability parameters for stress resistance from -73 to -96, with a coefficient of variation - 18.4-25.2% and with a breeding value - 130-139 are attributed to the most stable and plastic varieties. They provide valuable starting material for further study and use in the breeding process.

The purpose of the study is to improve the species composition of grass mixtures under irrigated conditions to increase their productivity, longevity and provide livestock with high-quality feed. The experiments were performed in 2019-2022 on old plowed lands located in the right-bank steppe of the north of Astrakhan region under irrigation. Irrigation method: sprinkling, 10 vegetation irrigations per season. The soil is light chestnut, medium loamy with a humus content of 0.90...1.00%. mobile phosphorus and potassium (according to Machigin) – 69 and 361.5 mg/kg, respectively. We studied 6 variants of grass mixtures: control (creeping wheatgrass, angustifolia bluegrass, awnless brome, coastal sedge, swamp grass, California cocklebur); grass mixture 1 – 25:25:25:25% (blue hybrid alfalfa, meadow clover, meadow timothy, meadow fescue; grass mixture 2 – 30:40:30% (meadow clover, multi-cut ryegrass, meadow fescue; grass mixture 3 – 50:50% ; (meadow clover and reed grass); grass mixture 4 – 25:25:25:25% (eastern goat’s rue, meadow clover, multi-cut ryegrass, meadow fescue; grass mixture 5 – 25:25:25:25% (meadow clover, meadow timothy) , multi-cut ryegrass, common beckmania); grass mixture 6 – 50:25:25% (meadow clover, festulolium, intermediate wheatgrass. The most productive were grass mixtures No. 1 and No. 2 – 147.6 and 156.3 t/ha of green mass, which higher than the control by 134.3 and 143.0 t/ha, respectively. All studied options were distinguished by high nutritional value - the content of feed units per 1 kg of dry biomass varied from 0.75 kg per 1 kg of feed for grass mixture No. 2 to 0.85. kg per 1 kg of feed for grass mixture No. 5. When feeding all grass mixtures with hay, the animals had a higher average daily weight gain (1.2...1.7 higher) in terms of nutritional value, compared to feeding with hay from natural grass. The high productivity and price of hay of legume-grass grass mixtures determine the high profitability (177%) of its production, which is 3.3 times higher than natural haymaking.
