Recently, much attention has been paid by grassland farmers to the problem of extending the productive longevity of grasslands of the pasture type. Field studies were carried out on the agropolygon of FGBNU VNIIMZ in the period from 2012 to 2018. The object of research was pasture grass stands created on the basis of pasture ryegrass (Loliurn perenne) and inter-genera festulolium hybrid (× Festulolium F. Aschers. Et Graebn). Two, three, and four species of grass mixtures with various leguminous and cereal herbs were studied in the experiment. The types and varieties of herbs were selected taking into account their potential productivity and sustainable longevity in the conditions of drained soils. Ryegrass grazing VIC 66, festulolium VIC 90, alfalfa changeable (Medicago varia Nakhodka), lotus horned (Lotus cornilatus Sun), creeping clover (Trifolium repens) VIC 70, red fescue (Festuca rubra) Sigma, red clover (Trifolium pratense) VIC 7, timothy grass (Phleum pratense L.) VIC 9, meadow fescue (Festuca pratensis) Sakharovskaya were used in the experiments. It has been shown that in the conditions of drained lands, such species as red fescue, alfalfa changeable, horned deer can be attributed to perennial grasses with a competitive advantage for long-term sustained production in multicomponent pasture agrophytocenoses. It has been established that the introduction of additional leguminous species into the grass mixture (alfalfa changeable and lotus horned) increases the period of use and increases the yield of a green mass of grass stands. Over the years of research (2013–2018), the highest average yield of green mass was obtained by grass stands with alfalfa variable and young horned — 24.5–28.2 t/ha, which exceeds the traditional grass mixture by 3.5–7.2 t/ha.

На агроэкологическом полигоне ВНИИМЗ в период с 2012 по 2017 год проводилось изучение ценотических особенностей многолетних трав на осушаемых почвах. Объектом исследований являлись пастбищные травостои, созданные на основе райграса пастбищного (Loliurn perenne) и  межродового гибрида фестулолиума (× Festulolium F. Aschers. et Graebn.). В опыте изучались двух-, трёх- и четырёхвидовые травосмеси из различных бобовых и злаковых трав. Виды и сорта трав подбирались с учётом их потенциальной продуктивности и устойчивого долголетия на осушаемых почвах: райграс пастбищный ВИК 66, фестулолиум ВИК 90, люцерна изменчивая (Medicago varia) Находка, лядвенец рогатый (Lotus cornilatus) Солнышко, клевер ползучий (Trifolium repens) ВИК 70, овсяница красная (Festuca rubra) Сигма, клевер луговой (Trifolium pratense) ВИК 7, тимофеевка луговая (Phleum pratense L.) ВИК 9, овсяница луговая (Festuca pratensis) Сахаровская. Установлено, что высокой конкурентной способностью и устойчивостью в изучаемых травосмесях отличались овсяница красная, люцерна изменчивая и лядвенец рогатый. Введение в травосмесь дополнительных бобовых видов (люцерны изменчивой Находка и лядвенца рогатого Солнышко) повысило урожайность зелёной массы травостоев. Урожайность зелёной массы травостоев на основе райграса пастбищного увеличилась на 0,77 т/га, или на 4,2%, фестулолиумовых — на 2,22 т/га, или на 12,1%. На осушаемых землях такие виды трав, как овсяница красная Сигма, люцерна изменчивая Находка, лядвенец рогатый Солнышко, можно отнести к многолетним травам с долголетним устойчивым продуцированием в многокомпонентных пастбищных агрофитоценозах. The research took place in 2012–2017 and analyzed cenotic characteristics of perennial grasses on draining soil. Swards of ryegrass (Loliurn perenne) and festulolium hybrid (× Festulolium F. Aschers. et Graebn.) performed as objects of study. The experiment tested two-, three- and four-component grass mixtures of various legumes and gramineous. Species and varieties of grasses were selected, considering their potential productivity and stable longevity on drying soil: ryegrass “VIK 66”, festulolium “VIK 90”, bastard alfalfa (Medicago varia) “Nakhodka”, birdʼs-foot trefoil (Lotus cornilatus) “Solnyshko”, white clover (Trifolium repens) “VIK 70”, red fescue (Festuca rubra) “Sigma”, red clover (Trifolium pratense) “VIK 7”, common timothy (Phleum pratense L.) “VIK 9”, meadow fescue (Festuca pratensis) “Sakharovskaya”. Red fescue, bastard alfalfa and birdʼs-foot trefoil showed high competitive ability. Introduction of additional legume species (bastard alfalfa “Nakhodka” and birdʼs-foot trefoil“Solnyshko”) increased green mass yield of grass mixtures. Green mass productivity of ryegrass mixtures improved by 0.77 t ha-1 or 4.2% while the festulolium ones — by 2,22 t ha-1 or 12.1%. Red fescue “Sigma”, bastard alfalfa “Nakhodka” and birdʼs-foot trefoil “Solnyshko”, being perennial species, grown on drained lands as grass mixtures have long-term stable productivity.

Seeded lawns is one of the most important links in the process of improving the forage base, ensure feed quality with high productivity. Mixtures of red clover crops (Trifolium pratense) with perennial grasses (Lolium multiflorum, Phleum pratense and Poa pratensis) has high productivity due to better utilization of ecological niches of the biotope (ROTAR I.et al.). These crops has advantages like high content of protein because of the red clover, economy-based fertilizer nitrogen from atmospheric nitrogen fixation by bacteria Rhizobium spp. located in the root of legumes. These seeded pastures get a balanced feed nutrients (proteins, carbohydrates, lipids), have a high palatability. The species Trifolium pratense has a greater capacity to restore the soil structure and also the enrichment of the macro-elements, like phosphorus and potassium (CARLIER L., et. al). Our experience took place in the village Simonesti, Cobătesti village of the Harghita county. The experimental field was located respecting the experimental technique rules in randomized blocks with a technique that includes three variants based on red clover plus a perennial grass (Lolium multiflorum, Poa pratensis and Phleum pratense). Every version was fertilized with two types of fertilizer: one liquid (gull) and one solid (stable manure) in four different doses in all three variants. The doses were: V1 = 0 gull; V2 = 5 t / ha gull; V3 = 10 t / ha gull; V4 = 20 t / ha gulle and V1 = 0 stable manure; V2 = 10 t / ha stable manure; V3 = 30 t / ha stable manure and V4 = 50 t / ha stable manure. In our studies we present the influence of fertilization with gull and stable manure on yield of green mass of all three variants. In general, both gull fertilization with manure favors grasses at the expense of installing legumes. The higher doses of fertilizer increase, the share of participant of grasses increases.

The effect of row spacing on seed and hay yields of 11 perennial grass species, including crested wheatgrass (Agropyron cristatum L.), intermediate wheatgrass (A. intermedium (Host.) Beauv.), a northern biotype of bromegrass (Bromus inermis Leyss.), a southern biotype of bromegrass, Russian wildrye (Elymus junceus Fisch.), meadow fescue (Festuca pratensis Hudson), creeping red fescue (F. rubra var. genuina L.), chewings fescue (F. rubra var. commutata Gaud), reed canary grass (Phalaris arundinacea L.), a turf-type timothy (Phleum bertolonii DC (P. bulbosum auct.)) and hexaploid timothy (Phleum pratense L.), was studied under a system with limited inputs of fertilizer and no weed control. The width of the row spacings ranged from 16 to 104 cm where seed yields were measured and from 27 to 93 cm where hay yields were measured. The seed yield of all grasses was greater at a row spacing of 16 cm than at row spacings of 60 cm or more. Hay yields of all grasses, averaged over four production years, were also greatest at narrow row spacings (27 cm). These yields decreased as row spacings increased to 49 through 93 cm. Row spacing had its greatest effect on hay yields during the first production year. After this period the effects of row spacing on hay yields were small.Key words: Row spacing, perennial grasses, seed yields, hay yields

The article presents the results of eight-year (2012-2019) field research on the formation of the production process of multicomponent legume and cereal grass stands while simulating pasture use. The comparison study was carried out with the use of basic grass mixtures: meadow clover (Trifolium pratense) VIK 7 + creeping clover (Trifolium repens) VIK 70 + timothy grass (Phleum pretense L.) VIK 9 + meadow fescue (Festuca pratensis) Sakharovskaya. Studied were agrophytocenoses with the use of pasture ryegrass (Lolium perenne) VIK 66 and festulolium VIK 90. As legume components, alfalfa changeable (Medicago varia) Nakhodka, birds-foot trefoil (Lotus corniculatus) Solnyshko and creeping clover VIK 70 were used. To increase the period of use, red fescue (Festuca rubra) Sigma, having the ability to regenerate itself was included into the composition of some mixtures. It has been established that alfalfa changeable, birds-foot trefoil and red fescue are the most adaptive to the conditions of drained lands. The analysis of the results of the study of the botanical composition of grass stands showed that over 8 years of growth, cereal grasses decreased their participation in the composition of herbage from 32.0-47.8 % to 1.8-22.3 % (excluding grass stands with red fescue). Four-component grass stands based on pasture ryegrass and festulolium with the use of timothy grass proved to be the most resistant to preserving sown grass species (46.3-63.7 %) and to weed infestation. Introducing additional legume species (alfalfa changeable and birds-foot trefoil) into the herbal mixture increased the period of use and significantly raised the yield of green mass of grass stands. The highest yield of green mass was obtained by herbage with alfalfa changeable and birds-foot trefoil - 23.7-26.4 t / ha, which in the seventh year of use exceeded the base grass mixture by 3.2-6.5 t / ha or 13.5-24.6 %. The results of fodder evaluation of legume-cereal ryegrass and festulolium grass stands, which denote the high-quality green fodder in conditions of drained soils of the Upper Volga Region, are presented.

Изучение урожайности трёхкомпонентных бобово-злаковых травосмесей с различными сортами клевера лугового проводилось в Тверской области на опытном поле ВНИИ мелиорированных земель в 2018–2020 годах. Опыт заложен в 2018 году на осушаемой дерново-подзолистой почве. Изучались следующие сорта многолетних трав: клевер луговой (Trifolium pratense L.) Кретуновский, Грин, Шанс, Фаленский 86; люцерна изменчивая (× Medicago varia Mart.) Вега 87; тимофеевка луговая (Phleum pratense L.) ВИК 9 и овсяница луговая (Festuca pratensis L.) Сахаровская. В 2020 году наиболее высокими темпами роста обладали травостои второго года пользования с ранними сортами клевера лугового Кретуновский и Грин в смеси с тимофеевкой луговой сорта ВИК 9 — 67–70 см при густоте стеблестоя 495–852 шт./м2. Наиболее продуктивными на осушаемых землях показали себя смешанные травостои люцерны изменчивой, клевера лугового и тимофеевки луговой. Трёхкомпонентные агрофитоценозы укосного типа на основе сортов клевера лугового Кретуновский, Грин, Шанс, Фаленский 86, люцерны изменчивой и тимофеевки луговой сформировали урожай кормовой массы 35–39,7 т/га. Травосмесь тимофеевки луговой с раннеспелым сортом клевера Шанс сформировала два укоса с выходом сухой массы 9,5 т/га, овсяницы луговой — 9,0 т/га. Отмечено хорошее качество полученной растительной массы: содержание переваримого протеина составило 18,9–19,5 г/кг при энергетической питательности 1,09–1,26. В растительной массе травосмесей с овсяницей луговой содержание переваримого протеина было выше, чем в смесях с тимофеевкой луговой, на 1,1 г/кг корма в первом и на 2,41 г/кг корма во втором укосе. По содержанию кормовых единиц в 1 кг корма питательность кормовой массы в зависимости от состава исследуемых смесей была равноценна — 0,23–0,24. The investigation took place in the Tver region on the trial field of the All-Russian Research Institute of Reclaimed Lands in 2018–2020. The research tested the yield of trinary legume-gramineous ecosystems with various varieties of red clover. The field trial was carried out on the drained sod-podzolic soil in 2018. The following perennial grasses were studied: red clover (Trifolium pratense L.) “Kretunovskiy”, “Grin”, “Shans”, “Falenskiy 86”; bastard alfalfa (× Medicago varia Mart.) “Vega 87”; common timothy (Phleum pratense L.) “VIK 9”; and meadow fescue (Festuca pratensis L.) “Sakharovskaya”. Growth rates were the highest in the mixtures with short-season red clover varieties “Kretunovskiy”, “Grin”, and common timothy. In 2020, these variants reached height of 67–70 cm and density of 495–852 plants per m2 in the second year. Trinary ecosystems to be cut with bastard alfalfa, red clover “Kretunovskiy”, “Grin”, “Shans”, “Falenskiy 86”, and common timothy provided the maximum yield on the drained lands — 35–39.7 t ha-1. The mixture of common timothy with short-season red clover “Shans” formed 9.5 t ha-1 of dry mass per two cuts, meadow fescue — 9.0 t ha-1. The feed mass showed high quality: digestible protein content was 18.9–19.5 g/kg, energy nutrition was 1.09–1.26. Mixtures with meadow fescue exceeded the ones with common timothy in digestible protein content by 1.1 g/kg in the first cut and by 2.41 g/kg — in the second one. Different variants showed almost no variation in feed units per 1 kg of forage — 0.23–0.24.

In this article are presented the results of a field experiment to study grass mixtures based on typical lawn grasses with complementary components. All varieties studied in the experiment are from domestic selection. The experiment was conducted on the experimental field of the Vyatka State Agricultural Academy in Kirov. Weather conditions during the years of this experiment were adverse for perennial grasses. Over the seven years of using of the lawns based on red fescue 'Sigma' and meadow grass 'Dar' with the addition of the perennial ryegrass 'Karat', meadow fescue 'Kvarta' and timothy grass 'VIK 85' were completely transformed into the single-species red fescue herbages (excellent quality) and meadow grass herbages (good quality). In the herbages with the addition of the orchard grass 'Hlynovskaya' share in the seventh year of life was 24–48%. To create high-quality long-term lawns in the conditions of the Kirov region can be recommended grass mixtures based on red fescue 'Sigma' with the addition of the perennial ryegrass, meadow fescue and timothy grass. The quality of meadow grass herbages is lower than that of red fescue, however, from grass mixtures based on meadow grass with the addition of the same complementary components, it is possible to create good quality lawns. The inclusion of the orchard grass in lawn grass mixtures is not recommended, due to the reduction of the quality of lawn herbages.

Aim. The purpose was to identify collection accessions – sources of valuable traits to use as starting material for creating varieties of perennial grasses in Western Ukraine. Results and Discussion. Perennial grasses play an essential role in improving the efficiency of forage production. They produce a fodder mass that contains major macro- and micronutrients, minerals, vitamins, amino acids, and other nutrients in available forms, with a high energy protein saturation. Practice shows that due to the introduction of varietal crops into production in combination with optimal technologies of their cultivation, which allows revealing the potential of each variety, it is possible to additionally obtain 20-30% higher yields of fodder mass annually and harvest 2 to 3-fold seed yields. In 2016-2020, a search was carried out and 570 new accessions of perennial grasses were recruited, of which 201 were legumes and 369 were graminaceous grasses. The collection contains 1,319 accessions, of which 232 are Trifolium pratense L., 115 are Trifolium repens L., 49 are Trifolium hybridum L., 107 are Lotus corniculatus L., 80 belong to other legume species (Medicago, Galega orientalis L. Galega orientalis L. and Trifolium species), 131 are Phleum pratense L., 187 are Dactylis glomerata L., 146 are Lolium perenne L., 53 are Arrhenatherum elatius (L.) J. et C.Presl., 67 are Festuca rubra L., 28 are Festuca trachyphylla L., 32 are Bromopsis inermis (Leyss.) Holub, 92 belong to other species of other types of graminaceous grasses (Festuca pratensis Huds., Festuca arundinacea Schreb., Agrostis alba L. etc.). Accessions that enter the Department are registered and sown for propagation in the field. After examination, valuable accessions are transferred to the National Depository and registered in the National Catalogue; the rest of the obtained seeds are used in working collections. Conclusions. The best collection accessions were identified by a set of economically valuable traits: sources of daily growth of shoots (30), winter hardiness (28), plant height (22), yield of green mass upon haymaking (28) and pasture (19) use, forage productivity (15), seed productivity (25), foliage (21), and disease resistance (23). They can be recommended as starting material to create varieties of perennial grasses with high yields of forage mass and seeds for various applications.

В данной статье представлены результаты сравнительной оценки 11 сортов клевера лугового и одного образца-дикороса, проведённой в Пермском НИИ сельского хозяйства в 2018–2019 годах. Все селекционные сорта сформировали полноценные первый и второй укосы или отаву в оба года использования. Дикорастущая форма формировала только один укос, демонстрируя особенность позднеспелого одноукосного типа. Сорта Кретуновский и Ранний 2 показали себя как типичные раннеспелые двухукосные. Другие сорта занимали промежуточное положение. Наибольший сбор сухого вещества обеспечивал образец-дикорос в оба года при крайне различных погодных условиях (1,266 и 1,259 кг/м2 соответственно). Дикорастущая форма и сорт Ранний 2 обеспечивали стабильные урожаи зелёной массы и сухого вещества независимо от возраста и погодных условий. Образец дикорастущего клевера имел более однородный фенотип по сравнению с сортом Пермский местный — стандартом для позднеспелого типа, что указывает на большую генетическую однородность. Согласно всесторонней оценке, включающей степень перезимовки, урожайность зелёной и сухой массы, характер цветения, созревания, формирования и конечный урожай семян, образец-дикорос имеет отличительные признаки позднеспелого (одноукосного) типа и может использоваться в качестве исходного генетического материала для дальнейшей селекции позднеспелых одноукосных сортов клевера лугового, характеризующихся экономически ценными свойствами: высокой устойчивостью к неблагоприятным условиям окружающей среды, высокой и стабильной урожайностью зелёной массы и семян. Исследования будут продолжены с оценкой ряда образцов дикорастущих форм клевера лугового, обнаруженных в 2019 году в природных биоценозах Пермского края. This article deals with the competitive trial of 11 varieties and 1 wild genotype of red clover conducted at the Research Institute of Agriculture in 2018–2019. All the varieties provided good yields of green mass both in the first and second cuts. Wild genotype provided only one cut as long-season one-cut type. “Kretunovskiy” and “Ranniy 2” performed as typical short-season two-cut varieties. Wild genotype produced the highest yield of dry matter (DM) under contrast weather conditions (1.266 and 1.259 kg/m2, respectively). Wild genotype and “Ranniy 2” formed stable yields of green mass and DM regardless of time period and weather. Wild genotype showed homogeneous phenotype compared to “Permskiy mestnyy” — long-season standard variety indicating high genetic uniformity. Such traits as winter hardiness, green and dry mass yields, flowering pattern, seed maturation, formation and production were evaluated. According to this evaluation wild genotype performed as long-season (one-cut) type showing high resistance to unfavorable conditions, high and stable yield of green mass and seeds. Therefore, it can be used a source of economically important traits for future breeding programs of red clover. Further investigations will focus on the evaluation of wild genotypes of red clover found in the Perm region in 2019.
