Relevance. The aim of the work is to create a green conveyor belt of perennial zoned grasses in floodplain meadows. For the first time in the Far North on the basis of field experience were studied species composition and mode of use of perennial grasses and legumes for green belt.Methods. The research was conducted in 2018–2020 in field conditions in the experimental field laboratory of horticulture of Yakut Scientific Research Institute of Agriculture named after M.G. Safronov in the Khangalassky ulus of the Sakha Republic (Yakutia). The soil of the experimental site is permafrost floodplain turf light loamy. Sowing was carried out in summer in the first decade of July.Results. The article includes data on the yield, chemical composition and nutritional value, and economic efficiency of perennial grasses. Over the years of research, the maximum yield was obtained from the grass mixtures of rumps (20)+ wheatgrass (16) — 4.0 t/ha of green mass, which is higher than the natural herbage by 2.4 t/ha of green mass. The yield of net sowing of sickle alfalfa (8 kg/ha) was 4.5 t/ha of green mass. The maximum yield from leguminous grass mixtures was provided by a two-component mixture of alfalfa (8 kg/ha) + stalk (10 kg/ha) — 4.9 t/ha of green mass. The highest content of crude protein when creating a green conveyor from single-species cereal crops is observed in red oatmeal — 18.2%, while the content of exchange energy is 9.1 MJ, feed units — 0.66, digestible protein — 122 g in 1 kg of dry matter. Of legumes and cereals the highest content of raw protein is provided by alfalfa (8 kg/ha) — 19.0%, while the content of exchange energy is 9.3 MJ, feed units — 0.70, digestible protein is 120 g per 1 kg of dry matter. When creating a green conveyor from grass stands, a high conditional net income is obtained when sowing boneless stalk (20 kg/ha) +w heatgrass (16 kg/ha) — 5688 rubles/ha, while the cost of production is 12,000 rubles/ha, the profitability is 90%.

In the course of studies, it was found that taking inoculation of Scarlet amaranth and Poterium polygama seeds with biologics has a positive effect on the formation of photosynthesis parameters. In amaranth agrocenoses during the panicle sweeping phase, the leaf surface area was significantly higher when seeds were inoculated with biological products than in the control variant for Kizlyarets cultivar by 23.1-36.3% and Valentina cultivar by 23.8-38.0%, the most effective the method was exogenous seed treatment with agric. The maximum parameters of photosynthesis were noted during seed maturation. So, on average for three years of research, the leaf area of the Kizlyarets variety was 64.1 and the Valentine variety 62.3 thousand m2 / ha, the photosynthetic potential, respectively, was 2.05 and 1.98 million m2 days / ha, the net productivity of photosynthesis - 8.56 and 7.66 g / m2 per day. The most intensive increase in the leaf area in the crops of the blackhead was noted in the budding phase, according to the experimental variants, it amounted to 40.8-45.3 thousand m2 / ha in the first year of use, and 41.9-46.8 thousand m2 in the second year of use / ha, in the third year of use - 42.8-47.4 thousand m2 / ha On average, over three years the largest collection of dry matter (6.9 t / ha), feed units (9.1 t / ha), digestible protein (1.45 t / ha) and metabolic energy (81.6 GJ) were obtained from Kizlyarets varieties when inoculating seeds with Agrika biological product. At the same time, the highest seed yield was obtained (1.31 t / ha), which is 2.39 times higher than the control variant and 1.44 times higher than the Valentina variety. Optimization of the plant’s mineral nutrition by seed inoculation with associative bacterial preparations provided for an increase in the productivity of the polygamous monofil. The yield of green mass of the Poterium polygama of the first year of use for an average of three years according to the experimental options was 28.5–31.8 t / ha, collection of dry matter – 7.3–8.2 t / ha, feed units – 4.36–4.87 t / ha, digestible protein - 0.56–0.65 t / ha, exchange energy - 88.7–99.6 GJ. The highest productivity of the blackhead was when treating seeds with Agrika with microelements together with Azotobacter: green mass - 31.8 t / ha, dry matter collection - 8.2 t / ha, feed units - 4.87 t / ha, digestible protein – 0.65 t / ha, exchange energy - 99.6 GJ, which significantly exceeds the performance of the control option. The treatment of seeds with biologics provided an increase in the seed productivity of the polygonidae by 91.7–223.1 kg / ha (10.1–24.6%). The highest seed yield in the first year of use is 1130.1 kg / ha, the second year of use is 1258.9 kg / ha, the third year of use is 1268.3 kg / ha, which significantly exceeds the control indicators by 27.3% and 27.8% was obtained during bacterization of seeds with Agrika, enriched with microelements and together with Azotobacter.

The article presents the data of assessing the productivity and nutritional value of selection samples of creeping clover in the nursery of the competitive variety testing of 2016 sowing for three years of use. The purpose of the research is to identify a promising breeding material of creeping clover for creating a variety with high productivity of green mass and seeds, suitable for mechanized harvesting of seeds for the conditions of the forest-steppe of the Middle Volga region. The research was carried out in 2017-2019 on the experimental field of a separate subdivision of Penza FGBSI FSC of BC in accordance with the methodological instructions for the selection of perennial grasses. On average over three years of use in terms of the yield of green mass – 15.00-16.44 t/ha, cultivar samples of creeping clover V-92, Yu-90, P-97, Pl-90-4 significantly exceeded the VIK-70 standard (14,01 t/ha) by 7.1-17.3%, for the collection of dry matter – 3.49-3.97 t/ha varieties V-92, Yu-90, P-97 and Pl-90-3 reliably exceeded the standard (3.29 t/ha) by 6.1-20.7%, in the collection of digestible protein – 0.44-0.49 t/ha, the varieties B-92 and P-97 exceeded the standard (0, 40 t/ha) by 10.0-22.5%. Maximum values of the yield of green mass (16.44 t/ha), dry matter collection (3.97 t/ha), digestible protein (0.49 t/ha), feed units (5.04 t/ha) and exchange energy (49.12 GJ/ha) on average for the years of testing showed the sample P-97. This specimen significantly exceeded the standard in terms of structural elements and seed yield by 50.5%, in the height of leaf petioles by 3.5% and peduncles by 2.5%, which is important for mechanized harvesting of seeds. When selecting for the productivity of creeping clover, one should pay attention to the signs associated with the yield of green mass and seeds. The length of leaf petioles correlates with the length of peduncles (r = 0.78), the number of seeds in the head (r = 0.46), the number of inflorescences in the head (r = 0.47), with the collection of dry matter (r = 0.31). The length of the peduncles correlates with the collection of dry matter (r = 0.30), with the number of inflorescences in the head (r = 0.54), and with the number of seeds in the head (r = 0.51). The number of inflorescences in the head correlates with the number of seeds in the head (r = 0.61) and with the yield of seeds (r = 0.31)

Использование микробных препаратов — перспективный путь повышения продуктивности сельскохозяйственных растений. В статье приведены результаты изучения влияния биопрепаратов, созданных на основе живых штаммов микроорганизмов Bacillus subtilis («Натурост»), Lactobacillus buchneri («Натурост-Актив») и Bacillus megaterium («Натурост-М»), на продуктивность и питательную ценность райграса однолетнего и клеверо-тимофеечной смеси. Исследование проводили в мелкоделяночном полевом опыте во ФГБУН ВолНЦ РАН (Вологодская область) в 2019–2020 годах. Под влиянием обработки биопрепаратами выход зелёной массы райграса возрастал на 13,7–65,5% в зависимости от опытного варианта. Продуктивность травосмеси клевера и тимофеевки увеличилась на 13,1–46,6% в зависимости от используемого биопрепарата, укоса и года исследования. Оценка питательной ценности райграса показала, что обработка биопрепаратами способствовала повышению содержания кормовых единиц в сухом веществе на 6,5%, также несколько увеличилось содержание обменной энергии, сырого и переваримого протеина, сахаров и жиров. Питательная ценность клеверо-тимофеечной смеси по содержанию кормовых единиц под влиянием биопрепаратов увеличилась на 15%. В опытах с райграсом бόльшая продуктивность зелёной массы получена при использовании препарата «Натурост-Актив», в опытах с клеверо-тимофеечной смесью отмечена бόльшая эффективность препарата «Натурост». В исследованиях 2019 года повышение питательной ценности зелёной массы у обеих культур в большей степени происходило под влиянием препарата, созданного на основе бактерий Bacillus megaterium. В 2020 году более выраженное увеличение содержания кормовых единиц, обменной энергии, сырого протеина, переваримого протеина и жиров происходило при внесении препарата на основе бактерий Bacillus subtilis. Microbial preparations were shown to be promising when increasing crop productivity. This article reports on the effect of biopreparations containing living strains of Bacillus subtilis (“Naturost”), Lactobacillus buchneri (“Naturost-Aktiv”) and Bacillus megaterium (“Naturost-M”) on the yield and nutritional value of annual ryegrass and clover-timothy mixture. Microplot field trial took place in 2019–2020. Biopreparations improved green mass yield of ryegrass by 13.7–65.5%. The productivity of the clover-timothy mixture increased by 13.1–46.6% affected by biopreparations, cut and year. Treatment with biopreparations increased feed unit content by 6.5% in dry matter (DM) as well as exchange energy, crude and digestible protein, sugar and fat. Biopreparations improved feed unit content of the clover-timothy mixture by 15%. Ryegrass produced the highest yield of green mass under “Naturost-Aktiv” application, while “Naturost” was more effective for the clover-timothy mixture. In 2019 Bacillus megaterium had the best effect on the nutritional value of crop green mass. The contents of feed units, exchange energy, crude and digestible proteins as well as fat grew significantly after Bacillus subtilis application in 2020.

In the course of the experiment, the effect of increasing doses of nitrogen fertilizers on the yield of clover of the meadow variety Nadezhny, entered in the State Register of Breeding Achievements in 2012, was analyzed. A comparison is also made of this influence with the timothy of the meadow variety Leningradskaya 204. It was established that the pre-sowing introduction of mineral nitrogen for clover and timothy has influenced the productivity of these crops, but the nature of this effect varies depending on the type of grass. The introduction of N20 against the background of P30K90, which provided an increase in control of 51.2% for green mass and 33.6% for air-dry matter, was optimal for meadow clover of the first year of life. For grassland clover second year of life, the best option was N0P30K90, which gave an increase of 56.6% to the control on green mass and 50.6% on air-dry matter. A further increase in the dose of nitrogen on the options caused a decrease in yield increase. Timothy meadow for two years of life was traced responsiveness to the provision of nitrogen. The most productive in all respects was the option N120P30K90.

The results of field studies for 2017 - 2019 are presented. yields of perennial grasses sown at different times of the growing season. Spring, summer, and winter sowing periods were compared. Alfalfa, clover, rump, and also their mixtures were sown in 2017 under the cover of barley. The value of the cover crop yield of spring and summer sowing periods did not differ significantly and amounted to 4-5 t / ha of absolutely dry matter. Winter barley crops have not formed. On average, over 2 years of use, the highest yields were observed in alfalfa-crust grass mixtures - 3.4 t / ha of absolutely dry matter. The lowest yield was obtained in the single-species seeding of the rump. Correspondingly, in the spring, summer and winter periods of sowing, the yield of rump was 1.6; 1.1 and 1.3 t / ha. With a late sowing period, the yield of perennial grasses is significantly lower compared to spring and summer. With winter sowing periods, the yield was the highest for grass stands of alfalfa and alfalfacrust grass mixture - 2.3 and 2.4 t / ha. It should be noted that in the second year of use, the yield by the sowing dates in single-species crops and grass mixtures is leveled. The winter crops of perennial grasses in the first year of use formed a low yield. Only in the second year (third year of life) the productivity of perennial grasses of winter sowing began to increase. Consequently, in the area under perennial grasses of the winter sowing period, during one growing season (the next year after sowing), the crop was not actually formed. Based on the data obtained, production can be recommended for spring and summer planting of perennial grasses under the cover of barley. The winter sowing period provides economically valuable crop yields only by the third year of life.

Productivity Potential

Alfalfa and sainfoin have always been the main perennial fodder legumes in the south of Russia. Because of their economic and biological properties, crop and fodder production have always relied on their cultivation and will rely on it in the future. Insufficient cultivated areas of these legumes make it impossible to provide livestock with balanced feed, to use climatic, soil and plant resources rationally. The study of the varietal composition of alfalfa and sainfoin developed in the FSBSI “Agricultural Research Center “Donskoy” showed that the productivity potential of these varieties makes it possible to obtain a fairly high yields of forage under various weather-climatic conditions. For 6 years the average yield of green mass of the standard variety “Rostovskaya 90” was 27.0 t/ha in the first cutting and 18.1 t/ha in the second cutting, and in the total for two cuttings it is 45.1 t/ha. In the first cutting for 5 years out of 6, the green mass pro­ductivity of the alfalfa varieties “Lyutsiya” and “Selyanka” significantly exceeded the standard variety. On average for two cuttings, green mass productivity of the varieties “Lyutsiya” (47.8 t/ha) and “Selyanka” (48.9 t/ha) was higher than that of the standard variety. The yield of absolutely dry matter of the standard variety “Rostovskaya 90” varied from 6.7 t/ha to 7.7 t/ha in the first cutting and from 4.3 t/ha to 5.2 t/ha in the second cutting. The yield of absolutely dry matter of the alfalfa varieties “Lyutsiya” and “Selyanka” reliably exceeded the standard variety in the first cutting, but in the second cutting their yield was equal to the yield of the standard variety. According to the green mass yield of one cutting, the studied varieties of sainfoin were as good as the alfalfa productivity in the first cutting. The green mass pro­ductivity of the standard variety “Zernogradsky 2” ranged from 24.4 to 31.1 t/ha, the green mass productivity of the sainfoin variety “Veles” ranged from 26.8 t/ha to 39.4 t/ha, and the green mass productivity of the variety “Sudar” ranged from 28.8 t/ha to 33.3 t/ha. The dry matter productivity of the sainfoin varieties developed in a similar way. The minimum dry matter productivity of the standard variety “Zernogradsky 2” was 6.1 t/ha, the maximum was 7.8 t/ha. The minimum dry matter productivity of the variety “Veles” was 6.7 t/ha and the maximum was 9.8 t/ha. The minimum dry matter productivity of the variety “Sudar” was 7.2 t/ha and the maximum was 8.8 t/ha. In total for 2 cuttings, the alfalfa varieties produced 7.45–8.12 thousand of fodder units, 2.29–2.57 t/ha of raw protein and 1.59–1.78 t/ha of digestible protein. The varieties “Lyutsiya” and “Selyanka” showed a higher yield of nutrients, compared with the standard variety. The nutrient productivity of the studied sainfoin varieties slightly yielded to the alfalfa varieties in the first cutting. On average they produced 3.89–4.55 thousand of fodder units per hectare, 1.34–1.55 t/ha of raw protein and 0.93–1.11 t/ha of digestible protein. In comparison with the standard variety “Zernogradsky 2”, the sainfoin varieties “Veles” and “Sudar” had a greater productivity of nutrients.

The Impact

The research explores the relation between productivity of binary grass mixture and mineral nutrition. The hypothesis assumes that nutrient value of the same forage depends on mineral nutrition of forage grasses. According to purpose of research, the authors specified the task which is seen to analyze the impact of mineral fertilizers on productivity and nutrition of forage mass of binary grass mixture sown under the cover. The object of the research is a binary grass mixture based on alfalfa (Medicago + sainfoin). Sowing was carried out under the barley and Sinapis cover on two mineral backgrounds: control (without fertilizers) and fertilized. Fertilizers were applied the day before sowing. Crop yield and the quality of harvested mass were assessed in the appropriate period which was the stage of Medicago budding. Two-year industrial and economic experiment highlighted necessity and efficiency of sowing Medicago binar grass mixtures under Sinapis cover with 25% lower sowing rate and apply mineral fertilizers dosed as N23P60K60 in the forest-steppe of Novosibirsk region. This application contributed to the highest output of metabolic energy in dry matter (37 GJ/ha). The authors observed a positive tendency on harvesting from 1 ha of fodder units (2.14 tons), digestible protein (0.35 tons), as well as the yield of dry (3.58 tons) and green mass (13.7 tons). In this variant the authors observed the highest output of metabolic energy in dry matter (37 GJ/ha). There was a positive tendency to harvest fodder units (2.14 tons), digestible protein (0.35 tons) pro 1 ha and get dry (3.58 tons) and green mass (13.7 tons).

Experimental data on the creation of fodder agrocenoses for the production of green feed in the spring and early summer period is presented. The research was conducted in 2014-2016 in the forest-steppe zone of the Trans-Baikal Territory. The study included winter and spring rye crops and cabbage. It was established that the promising crop that gives the earliest green feed is the winter rye of autumn sowing. It was characterized by a high regrow capacity and formed two yield cuttings in the tillering phase. The yield of green mass was 7.7 t/ha, dry matter – 1.36 t/ha, output of feed units was 1.34 t/ha, the amount of digestible protein – 279 kg/ha. In the phase of stem elongation, the figures were 10.0 t/ ha, 2.17 t/ha, 1.93 t/ha, 287 kg/ ha, respectively; in the earing phase (one cutting) – 9.3 t/ha, 3.30 t/ha, 2.65 t/ha, 287 kg/ha, respectively. Feed biomass was of higher quality when used in the period of tillering, where the content of digestible protein per one feed unit was 206-210 g. The spring sowings of winter rye were inferior to the autumn sowings in the amount of two cuttings in the tillering phase: green mass by 3.3 t/ha, dry matter 0.58 t/ha, feed units 0.58 t/ha, digestible protein 113 kg/ha; in the stem elongation phase: 5.5 t/ha, 1,27 t/ha, 1.15 t/ ha, 168 kg/ha, respectively. Crops of spring rape, oil radish and spring rye are also important, since they allow to obtain a sufficiently high yield in the early summer period. In the budding phase the yield of green mass of cabbage crops was 22.8 and 18.3 t/ ha, dry matter – 2.69 and 2.78 t/ha, feed units – 2.70 and 2.25 t/ha, digestible protein – 648 and 599 kg/ ha; in the flowering phase the figures for oil radish were 21.5 t/ha, 2.56 t/ha, 2.57 t/ha, 499 kg/ ha, respectively. In the tillering phase the figures for spring rye in the amount of two cuttings were 7.3 t/ ha, 1.31 t/ha, 1.11 t/ha, 210 kg/ ha, respectively; in the phase of stem prolongation – 3.8 t/ha, 0.82 t/ ha, 0,87 t/ha, 105 kg/ha, respectively.

Abstract As a result of three-year studies, we have established a growth in the yield and feed advantages of variable alfalfa in the variants with inoculation of seeds with virulent active strains of rhizobia. The total yield augmentation of green mass in the experimental variants over the three years of alfalfa life were 6.8–13.7 % compared to the control ones. The positive effect of inoculation with virulent active rhizobia strains on the total collection of dry matter was expressed in its increase in experimental conditions by 12.6–21.7 %. The highest yield of green mass, as well as dry matter was obtained in the variant with the inoculation of alfalfa seeds with the main production strain 425. The researched factor has a positive effect on the collection of feed units, digestible protein and feed protein units from 1 ha. The collection of feed units per hectare in the experimental versions increases by 1.1–1.3 times, the collection of digestible protein – by 1.2–1.4 times. The maximum substance of feed units and digestible protein per hectare was observed in the version with seed inoculation with strain 425a. The provision of a feed unit with digestible protein increases by 10.44–18.18 g or by 6.1–10.6 %.
