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.

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 main parameter of the breeding work with alfalfa in the ARC “Donskoy” is the improvement of fodder and seed productivity. Through the years the breeding work was carried out with 500–860 collection samples of alfalfa, alfalfa hybrids and alfalfa lines of the local origin. The main method of the breeding work was poly-crossing. It’s characterized with a multiple repetition of selections of the best plants from the populations, their self-pollination and crossing by free pollination in the plots of poly-crossing. It resulted in accumulation and concentration of favourable traits in the population. The selection promoted systematic improvement of synthetic populations according to economic-valuable traits, especially fodder and seed productivity. During the research, productivity of green mass of the standard variety ‘Rostovskaya 90’ was 28.2 t/ha in the first cutting and 19.0 t/ha in the second one on average. The varieties ‘Lyutsiya’ and ‘Selaynka’ produced 30.6 t/ha, 19.8 t/ha and 32.1 t/ha, 20.4 t/ha respectively. The sum of the harvested green mass of the standard variety was 47.2 t/ha, while ‘Lyutsiya’ produced 50.5 t/ha and ‘Selaynka’ 53.1 t/ha, that is on 7.0% and 12.5% larger than the standard. The similar result was obtained in productivity of dry matter. The total quantity of dry matter produced by the standard variety was 11.6 t/ha (two cuttings), the varieties ‘Lyutsiya’ and ‘Selaynka’ gave 12.6 t/ha and 12.8 t/ha that is on 8.6% and 10.3% more than the standard. The estimation of the breeding work with alfalfa in the preliminary and competitive variety testing allowed to identify the new alfalfa variety ‘Golubka’ and to send it to the State Variety Testing. In the competitive variety testing (2012–2016) the variety produced larger yields that the standard variety (productivity of all five 1-st cutting). With its average productivity of green mass (31.9 t/ha) it exceeded the standard on 13.1%. In the 2-d cutting its green mass productivity was 20.9 t/ha that is on 10.9% more that the standard.  With the average productivity of green mass the variety ‘Golubka’ produced 8.0 t/ha in the 1-st cutting and 4.9 t/ha in the 2-d, that is on 12.7% and 8.9% lager that that of the standard.  The variety ‘Golubka’ produced 52.8 t/ha green mass for two cuttings and 12.8 t/ha dry matter that is on 11.9% and 10.3% larger than the standard variety ‘Rostovskaya 90’. Seed productivity of the standard variety was 0.23 t/ha on average, the varieties ‘Lyutsiya’ and ‘Selaynka’ gave 0.25 t/ha, the new variety ‘Golubka’ produced 0.29 t/ha, that is on 8.7 and on 26.1% more than the standard.

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.

Each region is characterized by a certain set of natural conditions. Therefore, it is necessary to have varieties of forage crops that can realize soil and climatic potential of the zone and are resistant to various possible stress factors. The purpose of the research is: study the variety samples of meadow clover according to the complex of economically useful characteristics in the competitive variety testing; identify the most promising ones in the conditions of the European North of the Russian Federation. The research was carried out in 2017, 2018 and 2019 at the experimental field of FSUE “Kotlasskoe”, which is located in the south-east of the Arkhangelsk region. Such breeding methods as selection, hybridization, creation of complex hybrid synthetic populations were used to create the studied variety samples. The studies were carried out according to the guidelines of the Federal Research Center “VNIIK named after V. R. Williams” and methodology of the State variety testing of agricultural crops (under the general editorship of Fedin M. A.). Soil of the experimental plots is weakly podzolic clay, medium cultivated on Permian clays. Mid-early diploid variety ‘Niva’ was used as a standard. The experiment was laid on a bare fallow; four-fold replication. Sowing was carried out with a SKS-6-10 seeder. Variety samples were evaluated according to a set of biological and agricultural characteristics: winter hardiness, vegetation period per mowing mass, plant height, leafiness, dry matter collection, protein content, protein collection, seed productivity. Agrometeorological conditions during the years of research were different, which allowed us to obtain more reliable results in assessing studied breeding material. All presented promising breeding samples exceeded the standard one in terms of the studied basic economic and biological characteristics. According to each studied indicator, we selected the best varieties. On average, over the years of research, a comprehensive assessment allowed us to identify the most valuable varieties that can form stable feed and increased seed productivity in northern conditions. They are K-2003, SD-289, K-1809, K-1556, ‘Taezhnik’. Winter hardiness of these samples varied from 84 to 94 %, dry matter collection – from 9.0 to 9.9 t/ha, seed yield – from 256 to 309 kg/ha, protein collection – from 1.26 to 1.35 t/ha. Variety ‘Taezhnik’ was included in the State Register of Breeding Achievements in 2020 for the 2nd region.

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 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).
