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 %.

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.

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 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. The purpose of the research was to study the effect of feeding by sainfoin haylage in the dry period (21 days before calving) and in the period of early lactation (50 days after calving) on the metabolic processes of dairy cows and the results of reproduction. The article gives the brief description of sainfoin (Onobrychis arenaria Kit.) as a valuable feed protein crop that can be successfully cultivated in Perm region conditions. High sugar content in sainfoin forage was noted 4.86 %, which is 1.6 times higher compared with standard class 1 for legume haylage first class. Methods. Experiments for use of sainfoin haylage in feeding highly productive cows were conducted in 2018. Cows of the experimental groups received a diet including sainfoin haylage. Cows in the control group received 5 kg of poaceous grass hay as a fodder. The first experimental group got 50 % of forage dry matter as sainfoin haylage. The second experimental group received 100 % of forage dry matter as sainfoin haylage. Results. Hay replacing by equal dry matter amount of sainfoin haylage provided positive effect on immuno-biochemical parameters of cows blood. The protein content increased in the blood plasma of cows during the time of the experiment: in the second experimental group by 4.3 g/l (5.47 %, p < 0.01) and reached 82.80 g/l, in the first experimental group by 1.72 % (p < 0.05), in the control – by 2.28 % (p < 0.05). Feeding sainfoin haylage to cows had a positive effect on their reproductive functions. The service period for cows of the second experimental group was shorter by 8.1 days (9.28 %, p < 0.01) compared with the first experimental group and by 21 days (24.05 %, p < 0.05) shorter than in the control group. The scientific originality of the work is that for the first time the biochemical composition of sainfoin was studied thoroughly in Perm region and the results of sainfoin haylage feeding to animals were presented.

The paper discusses the results of long-term research in the competitive variety testing of the sainfoin variety ‘Shuravi’, introduced into the State List of breeding achievements and approved for use in 2019 in the North Caucasus and Nizhne-Volga regions of Russia.The sainfoin variety ‘Shuravi’ is a complex hybrid species obtained by the methods of individual-family selection and polycross followed by massive negative selection. According to the most morphological and biological characteristics, the variety has been assigned to the Transcaucasian species. The plants are of tall height (95-105 cm). The bush is semi-upright (40%), upright (40%) and semi-sprawling (20%). The root system is vertical with a well-defined main root. The stalk is rough, thick and hollow inside. The kernels are of medium size, mainly with spines. 1000 kernel weight is 18–20 g. The vegetation period ‘sprouts – full ripeness’ is 85–90 days, and the mowing ripeness of the green mass is 45–55 days. According to resistance to major diseases, the variety is not inferior to the standard variety ‘Zernogradsky 2’. The productivity of ‘Shuravi’ green mass during the State variety testing was on 9.6% higher than that of the standard variety, dry matter was on 14.7% higher and seed productivity was on 17.6% higher. In the following years of study in a competitive variety testing, the variety ‘Shuravi’ exceeded the standard variety on 10.3% in green mass productivity and on 9.8% in dry matter. According to the yield of fodder units per 1 hectare, raw and digestible protein, the variety exceeded the standard on 17.0, 15.7 and 16.1% respectively. Exchange energy content per 1 kg of dry matter and supply of a fodder unit with digestible protein in the variety ‘Shuravi’ was at the standard level.The use of the sainfoin variety ‘Shuravi’ as a green fertilizer makes it possible to cover fresh standard organic matter on 9.8–14.7% and nitrogen on 1.8–2.4 kg more compared with the standard; the percentage of phosphorus and potassium is the same as with the standard variety ‘Zernogradsky 2’. In general, when using sainfoin green mass as green manure, soil is supplied with much more such basic nutrients as nitrogen, phosphorus and potassium than when applying the same amount of good quality manure.

In Iran milk production, in dairy cows, is based mainly on intensive systems in which cereals and industrial by-product are the most important source of nutrients. So, high digestible protein feeds are often desired for supplementation of high producing dairy cows to meet their amino acid requirements. Incubation of feeds in nylon bags in the rumen of fistulated ruminants have been used to evaluate the extent of digestion. In addition, the mobile bag technique has been used to measure intestinal digestibility of undegraded dietary protein and intact feed protein (Mesgaran, 2002). The work described in this summary assessed the digestibility of dry matter and protein, using ruminal and intestinal mobile nylon bag technique, of some tropical (Iranian) feeds used in dairy cow diets.
