Abstract In the conditions of the forest-steppe of the Central Black Earth region, the issue of the sustainable development of forage production, which can be increased through the expansion of the range of cultivated species of perennial legumes, has become relevant. The need to increase the share of areas of perennial grasses is connected with the fact that natural lands and annual forage crops have low productivity. Forage grasses are characterized by a number of unique economically valuable properties and characteristics. In this regard, there is an urgent need to increase their sown areas, as well as to improve natural lands, create hayfields and pastures. One of the limiting factors is the insufficient provision of seeds for a new fodder crop - Vys clover of a kura variety. It is kura clover that plays an important role in the creation of a solid forage base for animal husbandry in the Tambov region. Kura clover (Trifolium ambiguum Bieb) is characterized by a number of valuable traits and properties. In this regard, for the first time in the Central Black Earth Region, its biology and morphological development began to be studied and the optimal terms and methods of sowing this perennial legume crop are being developed. It will allow obtaining stable seed yields. The technology for obtaining seeds of this forage crop of the Vys variety in the forest-steppe conditions of the Central Black Earth Region is currently in the process of development. Therefore, the ongoing research on agrotechnical methods of the cultivation of kura clover seeds is very relevant and the development of individual agricultural methods of its cultivation technology of seeds is one of the important tasks of forage production.

Abstract In the context of the progressive trend of aridization of the climate of the main agricultural regions in the forest-steppe and steppe zones, the problem of increasing and stabilizing the high productivity of forage crops is becoming more acute. Yellow alfalfa (Medicago falcata L.) is highly resistant to abiotic stresses such as drought and low temperatures. This crop is resistant to extremely stressful conditions for cultivation in arid conditions, high production potential for the production of various types of bulky forage. The limiting factor of the effective economic use of yellow alfalfa in the Central Black Earth region of Russia is the insufficient number of zoned varieties, only three. The zoned varieties of alfalfa that exist today do not fully meet the requirements of modern forage production, and the tasks of developing new varieties with increased productivity, competitive ability in grass mixtures and increased longevity are becoming urgent. A highly productive variety of yellow alfalfa Pavlovskaya 7 was previously created at the Voronezh Experimental Station for perennial grasses. The Pavlovskaya 7 variety is characterized by high resistance to fungal diseases and mycoplasmosis, drought resistance, and long (up to 12 years) productive longevity. Currently, the station is completing selection work to develop a new variety of yellow alfalfa with a complex of economically valuable traits and properties for conditions of insufficient moisture.

In the world more than 100 types of crops are cultivated on the fodder purposes, including perennial grasses, corn, fodder and forage crops account, which provides about 70% of the livestock’s necessity. Among the perennial grasses, the leading position, both in areas under crops and the yield, is alfalfa crop, which is grown in 165 countries around the world according to the Food and Agricultural Organization of the United Nations, especially in the countries of Americas (20-25 million hectares). Furthermore, the palatability ratio of green and dry alfalfa is significantly higher, compared to other legumes perennial grasses. It is difficult to overestimate the importance of alfalfa forage production in the modern forage production. This paper presents the current issues of growing alfalfa on different backgrounds of mineral nutrition. In our country its acreage needs to be expanded to 350 hectares (40% of the acreage of perennial grasses), because the farming biologization without the inclusion this crop in the field, forage and farms crop rotation is theoretically impossible and not feasible. In order to obtain the high biomass of at least 23 tons per hectare and agriculture biologization on gray forest soils of the Republic of Tatarstan we recommend to cultivate alfalfa mixed with awnless rump and meadow fescue in the ratio of 0,70:0,15:0,15. In households with high use of chemicals so that to obtain for more than 36 tons per hectare of green herbage mass in polyspecific grasses, it should prevail crop components (awnless rump and meadow fescue), which are in a leading position, according to the impact on the agro biological properties of the soil of Kama zone of the Republic of Tatarstan.

В Центральном Черноземье большая часть кормов производится на пашне. В связи с этим эффективность животноводства зависит от стабильного обеспечения животных качественными и недорогими кормами. Наиболее доступными кормами являются многолетние травы. Внедрение новых видов и сортов нетрадиционных кормовых трав с улучшенными хозяйственно полезными признаками является важным резервом для кормопроизводства. Межродовой гибрид фестулолиум ценная кормовая культура для полевого и лугового травосеяния, которую можно использовать на зелёный корм, сено, силос, сенаж, а также при создании культурных сенокосов и пастбищ. В связи с этим для более широкого внедрения в производство требуется научная разработка приёмов возделывания, обеспечивающих получение высоких и устойчивых урожаев семян. Важными элементами технологии возделывания фестулолиума на семена являются норма высева семян и способ посева. В представленных исследованиях, проведённых в 20062009 годах, изучены биологические особенности и семенная продуктивность при использовании разных норм высева и обычного и черезрядного способов посева. По результатам проведённых исследований можно отметить, что посев фестулолиума рядовым (15 см) или черезрядным (30 см) способами с нормой высева 6,0 кг/га позволяет сформировать разреженный слабополегающий травостой. Ассимиляционный аппарат фестулолиума наиболее продуктивно ассимилировал при обычном и черезрядном способах посева с нормами высева 6,0 и 9,0 кг/га, о чём свидетельствует максимальное значение фотосинтетического потенциала 10291090 тыс. м2сут/га. Чрезмерное загущение посевов (до 12,0 кг/га) отрицательно сказалось на элементах структуры урожая, привело к полеганию растений, уменьшению их продуктивности. Установлено, что максимальная семенная продуктивность фестулолиума получена в травостоях с нормой высева 6,0 кг/га и густотой стояния 130133 шт./м2: при рядовом способе посева урожай семян в среднем за 3 года составил 604,3 кг/га, а при черезрядном 652,3 кг/га. In the Central Non-Chernozem region the greatest part of forage comes from grasslands. Stable production of high-quality and low-cost feeds is a key to effective Animal Husbandry. Perennial grasses are the most popular source of fodder. Introduction of new unconventional genotypes of such grasses carrying improved economically important traits is crucial for forage production. Festulolium intergeneric hybrid is a valuable crop that can be used to produce green forage, hay, silage, haylage as well as to maintain pastures and grasslands. Its large-scale cultivation requires new techniques providing high and stable yield. Seeding rate and pattern significantly affect festulolium performance. This paper reports on festulolium biological parameters and seed productivity analyzed in 20062009. Row and skip-row planting patterns as well as the seeding rate of 6.0 kg ha-1 resulted in sparse lodging-resistant swards. Seeding rates of 6.0 and 9.0 kg ha-1 provided the highest photosynthetic potential 10291090 thousand m2days ha-1. High plant density (up to 12.0 kg ha-1) negatively affected festulolium performance and led to lodging. The seeding rate of 6.0 kg ha-1 and festulolium density of 130133 plants/m2 resulted in the highest seed productivity: 604.3 and 652.3 kg ha-1 under row and skip-row planting patterns, respectively.

Among the factors that determine the efficiency and success of the livestock industry is the science-based production of high quality feed. The solution to this problem is impossible without field feed production, engaged in the cultivation of annual mixtures. Among the large number of forage crops in the western forest-steppe are worthy of annual mixtures, in particular winter, which is highly valued for adaptability to growing conditions, especially in climate change. Despite the considerable part of the conducted researches on the development of technology of cultivation of winter forage crops, the question of optimization of their component composition and increase of stability of the most economically valuable species in the conditions of climate change remains relevant. Field studies were conducted in accordance with the common methods of forage production at the collection and research field of the Separate unit of the National University of Bioresources and Nature Management of Ukraine «Zalishchyky Agricultural College. E. Khraplyvy» during 2016-2018. On the basis of the experimental data, the optimal elements of the technology of cultivation of agrophytocenoses of Pannonian Viking with rye winter and triticale winter for the conditions of the Western Forest Steppe were identified. It was found that the highest yield of 1 ha of fodder units and exchange energy among the grass-root mixtures (4.50 t and 62.8 GJ) was agrophytocenosis, which included the cultivation of Pannosk in the amount of 2.5 million / ha of similar seeds with winter rye - 75% of the total sowing rate in single-species sowing, and among the ex-tritical (5.09 t and 64.6 GJ) - variant with sowing of the same seeding rate of legume component and winter triticale - 25% of the total sowing rate in single-species sowing. Pannonian wiki seeds in both variants were treated before sowing growth promoter. The results of the research will help to strengthen the forage base for animal husbandry and increase the productivity of farm animals.

Livestock farming is a fundamental economic activity for the semi-arid region, but it is directly influenced by factors such as soil characteristics, forage quality and rainfall seasonality. The irregularity of these factors reduces productivity levels, making them dependent on climatic conditions. In this sense, the knowledge of the main causes that reduce productivity and the adoption of resilient agricultural practices are essential in reducing the seasonal effects of the climate, increasing the supply of forage in the period of water scarcity. The use of adapted forage crops and with productive potential constitutes an efficient agricultural resilience practice, among which stands out the forage cactus, sorghum, millet, pigeon pea and sunflower. These are constituted with a high capacity for water conversion into dry matter, nutritional complementation and increased production. In addition, the implementation of practices (e.g. intercropping, irrigation, densification, mulch, etc.) contribute to the optimization of natural resources and provide better results in the continuous subsidy of forage production. With this, the present study aimed to present the environmental characteristics of the Brazilian semiarid region, to expose concepts about the levels of productivity and the main factors of the production gaps, in addition to disseminating mitigation strategies of forage production. After compiling this information, it highlights the importance of adapted forage crops and the adoption of agricultural management practices as strategies to mitigate the seasonal effects of the climate, contributing to the continuous subsidy of forage production. At the same time, the Yield Gap analysis allows for a broader knowledge of the limiting factors of production, directing agricultural planning more efficiently.

На примере трёх агроэкологических районов Хакасии показано влияние почвенно-климатических и ландшафтных особенностей территории на структуру растениеводства и развитие животноводства. Основные посевные площади в республике занимают зерновые и кормовые культуры. За период 2000–2019 годов относительно 1990 года произошло уменьшение посевных площадей по республике в 2,6 раза, по агроэкологическим районам — соответственно в 2,3; 2,3 и 1,6 раза. Доля кормовых культур в структуре посевов по Хакасии за 2000–2019 годы составляет 51,9%, в сухостепном — 79,5%, степном и лесостепном районах — 48,3 и 48,5%. Показатели плодородия почвы по содержанию гумуса показывают, что в республике в целом почвы пашни содержат 4,7% гумуса, наименьшее содержание — в сухостепном районе (3,5%). В настоящее время 84,6% пахотных земель характеризуются низкой и средней обеспеченностью подвижным фосфором. Поэтому переход земледелия на биологическую основу предусматривает восстановление деградированных агроландшафтов и сохранение плодородных свойств почв за счёт широкого внедрения травосеяния. Среди кормовых культур за период 2000–2019 годов на однолетние травы приходится по республике 27,6% и по районам — 18,0, 29,8, 36,3%; на многолетние травы — соответственно 63,1, 82,0, 52,5, 56,3%. В республике в 2019 году естественные сенокосы составили 160,4 тыс. га (8,3%), пастбища — 1019,8 тыс. га (53,3%). Их состояние требует проведения комплекса мероприятий, включающих использование технологий поверхностного и коренного улучшения. Для увеличения посевов трав необходимо существенное улучшение состояния семеноводства. Для повышения эффективности семеноводства однолетних и многолетних трав в республике необходим комплекс мер по совершенствованию форм его организации и специализации для создания единой системы размножения, начиная с питомника первичного семеноводства суперэлитных, элитных и репродукционных семян. The effect of the environment of three districts in Khakassia was tested on crop production and animal husbandry. Most farm lands are occupied by grain and forage crops in the Republic of Khakassia. In comparison to 1990 farm land area decreased by 2.6 times there for 2000–2019 as well as by 2.3, 2.3 and 1.6 times — in the districts studied, respectively. Forage crop proportion amounted to 51.9% for 2000–2019, in the dry steppe — 79.5%, steppe and forest steppe — 48.3 and 48.5%. Farm lands contained 4.7% of humus, the lowest concentration being in the dry steppe (3.5%). Currently 84.6% of farm lands show average to low content of soluble phosphorus. Biologization of arable farming will be focused on land restoration and maintaining soil fertility via the introduction of wide range of grasses. The proportion of annual forage grasses totally amounted to 27,6% for 2000–2019, in the districts — 18.0, 29.8, and 36.3%; perennial grasses — 63.1, 82.0, 52.5, 56.3%, respectively. In 2019 the acreage of natural haylands amounted to 160.4 thousand ha (8.3%), pastures — 1019.8 thousand ha (53.3%). The poor condition of farm lands requires the complex of effective tillage techniques. To increase the area of grass cultivation improved seed production is needed. Optimization of seed production includes the development of a unified reproduction technology starting from a nursery of primary seed growing.

Continued improvements in home grown forage consumption are needed to support the long-term profitability of the dairy industry in southern Australia. Most home grown forage currently comes from perennial ryegrass pastures, which have significant limitations in the southern Australia environment. These limitations threaten future productivity gains, and we therefore consider opportunities for using other plant species. Data on the production of alternative perennial grasses, brassica summer crops, C4 summer crops and winter cereals grown for whole-crop silage are limited and generally show large variation in yields between sites and years. Simulation models suggest that, once the base ryegrass pasture is well-utilised, incorporating complementary forages can return $70 - $100/ha extra operating profit for every additional tonne of home grown forage DM consumed per ha. Double cropping (winter cereal or annual ryegrass followed by a summer crop of turnips or maize) and summer-active pastures such as tall fescue show particular promise. Further information is required on how to integrate these forages into whole farm feeding systems to realise the additional profit with manageable business and environmental risk.

Perennial warm-season pasture grasses used in Florida become dormant in late fall and winter because of short days, cooler temperatures, and frosts. Many livestock producers may choose to establish cool-season annual pasture species to supplement their forage production. These plants are usually higher in total digestible nutrients (TDN) and crude protein (CP) than summer perennial grasses, translating into greater animal performance (Dubeux et al., 2016). Planting and growing these forage crops can involve considerable expense and is somewhat risky because rainfall is often unpredictable during the fall establishment period. The species and varieties for potential use vary in the distribution of production during the cooler months and in the type of soils where they are best adapted. This publication provides the most up-to-date information on current adapted cool-season forage varieties. The recommendation of varieties is based on multi-location, multi-year cultivar evaluation experiments that may include trials in Georgia and other states.
