Исследования выполнены в Пензенской области в 2014 2018 годах. Клевер ползучий (Trifolium repens L.) многолетнее травянистое растение, которое можно использовать для коренного улучшения состояния лугов и пастбищ. Цель селекционной работы с клевером ползучим в Пензенском НИИСХ создание сорта с урожайностью зелёной массы 14 16 т/га, устойчивой семенной продуктивностью (150 250 кг/га), выдерживающего трёхчетырёхкратное стравливание или скашивание, переносящего кратковременную засуху, пригодного к механизированной уборке семян. Представлена характеристика нового сорта клевера ползучего Изумруд, переданного в 2018 году на государственное сортоиспытание. Метеорологические условия отличались по годам исследования, что позволило достаточно полно оценить перспективность сортобразца. По результатам трёх циклов конкурсного испытания (2015 2017 годы) урожайность зелёной массы нового сорта Изумруд составила 19,48 т/га, сбор сухого вещества 4,34 т/га, урожайность семян 151 кг/га, что на 13,7, 18,4 и 18,9 выше стандарта ВИК 70 соответственно. Содержание сырого протеина в сухом веществе составило 22,4 26,9, клетчатки не превышало 27 31. Повреждаемость вредителями слабая, поражаемость бурой пятнистостью и мозаикой клевера ползучего слабая, ниже стандартного сорта. Сорт высокоустойчив к корневым гнилям, раку клевера, аскохитозу. Сорт Изумруд пригоден к механизированной уборке семян. Высокая засухоустойчивость (5 баллов) и зимостойкость (96 100) нового сорта позволяет рекомендовать его для сенокосного и пастбищного использования во всех зонах распространения культуры. Экономический эффект при использовании на кормовые цели составляет 11,2 тыс. руб./га, на семена 7,2 тыс. руб./га. The investigation took place in the Penza region in 2014 2018. Breeding of a new white clover variety aimed at the development of a genotype that had green mass productivity of 14 16 t ha1, stable seed yield of 150 250 kg ha1, high resistance to triple or quadruple cutting, shorttime drought and automized harvesting. This paper gives the description of white clover Izumrud that was sent to the State variety trial in 2018. The variety was tested under the different weather conditions. Three years of the competitive variety trial (2015 2017) showed that its green mass productivity amounted to 19.48 t ha1, dry matter (DM) content 4.34 t ha1, seed yield 151 kg ha1, exceeding the standard variety (VIK 70) by 13.7, 18.4 and 18.9, respectively. Crude protein content was 22.4 26.9, fiber up to 27 31. Izumrud also exceeded VIK 70 in tolerance to pests, Pseudopeziza trifolii and mosaic virus. The variety had high resistance to root rot, clover wilt and Ascochyta leaf spot. It tolerated automized harvesting, drought and cold and was recommended for farm cultivation. Its economic efficiency amounted to 11.2 thousand RUB ha1 under forage production and 7.2 thousand RUB ha1 under seed production.

Number Of Seeds

A field experiment with the cultivation of white clover for seeds (Barda cv.) was carried out in 2009–2012, in the Experimental Farm in Parczew (22°53'60"E, 51°37'59"N), on typical brown soil (bonitation class IVb), by the split-plot method, in four replicates. The studies included: foliar fertilization with microelements (B + Mo) and attractant – Pollinus. The number of heads per 1 m2, number of pods and seeds in the head as well as the seed yield were determined. Weather conditions had the decisive influence on the yield of seeds and main elements of its structure. The highest seed yield (305.4 kg·ha–1) was obtained in 2010 characterized by more favorable thermal conditions and rainfall in the generative clover sub-period, slightly lower in 2012 (287.7 kg·ha–1), and the lowest in 2011 (49.3 kg·ha–1). Fertilization with microelements (B + Mo) significantly increased the number of heads per 1 m2, the number of seeds in the head and the seed yield. The attractant used at the beginning and full flowering of clover significantly increased the yield of seeds by 35.2 and 78.0 kg·ha–1, respectively. The highest yield of white clover seeds (482.6 kg·ha–1) was obtained due to foliar fertilization with boron and molybdenum and using the attractant – Pollinus to fully flowering plants.

In the breeding nurseries and also in the competitive variety trial, the initial material of the meadow clover (Trifolium pratense L.) of the double-cut diploid was tested. The aim of the research is to select the most economically useful cultivars and create a new early-maturing variety. In the selection was used free pollination method, free and limited pollination method, mass and individual selection, polycross. Research was done from 2009 to 2014 in a laboratory and breeding crop rotation in the Smolensk State Agricultural Experimental Station named after A.N. Engelhardt. Methods of research are widespread. Clover was grown on sod-medium podzolic light loamy soil in contrasting weather conditions of the growing season. Methods of cultivation were typical for the Smolensk region. From 2011 to 2014, the best selective number was the S-434. It is early-maturing (period from spring growth till first cutting is shorter than that of the standard for 5…7 days; till seeds ripening – for 8…10 days), has high winter hardiness (97,4%, or +5,5% to standard), green mass yield for two cuttings – 69,8 t/ha (+25,5% to standard), forage productivity of 17,3 t/ha of air-dry matter (+26,3% to standard), seed yield of 330 kg/ha (+17,9% to standard). The crude protein content was 17,3% of dry matter (more than in the control by 1,3%). Growing of selective number S-434 on seeds is 8% more profitable. Selective number S-434 is named Pochinkovets. In 2018 he was registered in the State Register of Selection Achievements.

Среди многолетних трав клевер ползучий (Trifolium repens L.) является одним из лучших бобовых компонентов для создания культурных луговых и пастбищных агрофитоценозов в районах с умеренным климатом. На основе биологических особенностей клевера ползучего показана эффективность использования этой культуры для лугопастбищного кормопроизводства страны. Дан краткий анализ опыта возделывания клевера ползучего за рубежом. Показано значение хозяйственно полезных признаков сортов на эффективность их использования в травосмесях. Приведён материал по ботанической классификации разновидностей клевера ползучего и особенностям хозяйственного использования сортов разных морфотипов. Показана различная эффективность импортных и отечественных сортов клевера при их возделывании в почвенно-климатических условиях России. В настоящее время в Государственном реестре селекционных достижений, допущенных к использованию на территории РФ, зарегистрировано 27 сортов клевера ползучего, из них девять (33) отечественной селекции. Актуализирована необходимость усиления селекционной работы по выведению новых сортов, адаптированных к разнообразным почвенно-климатическим условиям и определённым режимам пастьбы. На основании этого обозначены направления селекции. Высокий рыночный спрос вызывает необходимость организации товарного семеноводства клевера ползучего сортов отечественной селекции. Установлено, что основной объём семян завозится из-за рубежа. Однако сорта зарубежной селекции мало приспособлены для произрастания в континентальном климате России. В статье в ретроспективе показано состояние и перспективы семеноводства клевера ползучего в России, включая систему воспроизводства его семян. Представлена научно обоснованная потребность в необходимых объёмах производства посевного материала на разных этапах репродуцирования для обеспечения лугопастбищного кормопроизводства. Для существенного увеличения сборов семян клевера ползучего предложено широко внедрять в производство сортовые посевы при оптимальных технологиях их выращивания, что позволит раскрыть потенциальные возможности каждого сорта в конкретных почвенно-климатических условиях и повысить урожайность семян в 23 раза. White clover (Trifolium repens L.) is one of the best perennial legume components for grassland and pasture ecosystems in regions with temperate climate. This report describes the effectiveness of this crop in forage production basing on its biological traits. It presents the experiment on clover cultivation abroad. The influence of economically important traits is shown on clover performance in grass mixtures. The article includes white clover botanical classification and cultivation methods of different morphotypes. Performances of foreign and domestic varieties were tested under Russian environment. Currently State Register for varieties accepted for cultivation in Russia lists 27 white clover varieties, and nine of them (33) are domestic. It is important to work further on breeding of new clover varieties adapted to various conditions. There is a high demand for white clover seeds of domestic origin. The main part of white clover comes from abroad. However, such varieties poorly grow under Russian climate. This paper shows the state and perspectives of white clover seed production in Russia. When producing grassland forage efficient seed production of this crop is of great importance. Introduction of white clover varieties to particular regions is a way to stimulate its seed production using optimal cultivation techniques.

Soybean [Glycine max (L.) Merr.] has long been used as a forage crop but its morphological development and forage potential have not been studied extensively. A study was conducted using oilseed soybean cultivars of different maturity to determine their morphological development, forage yield, seed components and seed yield at the University of Ankara, Turkey. Five soybean cultivars OAC Salem (earliest), OAC Bayfield (midearly), OAC Eclipse (mid-early but later than OAC Bayfield), OAC Glencoe (full-season soybean) and SA.88 (late), were used in the study conducted in 2000 and 2001. The full-season cultivar OAC Glencoe was the tallest cultivar, and had the highest levels of fresh and dry matter yield and crude protein yield among soybean cultivars in both years. Therefore, OAC Glencoe is considered to be the most suitable soybean cultivar for forage production when intercropped with corn in Ankara region of Turkey. However, attention should be given to the earliest maturing cultivar OAC Salem that had the highest seed yield and better relative seed composition of all the cultivars.

The results of studies on the formation of seed herbage of white clover varieties Lugovik of the second year of life are presented, the productivity of herbage and seed yield in variants of experiment is given. The yield of green mass differs significantly over the years. This is due to the fact that in 2020 the herbage dried up on the root, it became possible to get good hay. Of all the variants, the highest yield of seeds was collected from plots where white clover grew in its pure form, the lowest yield was in a mixture of white clover with pasture ryegrass. Thus, the cultivation of white clover "Lu-govik" in the conditions of sod-podzolic soils of the Kirov region is more effective in its pure form.

The need to restore the dairy cattle population and the feed base in the North-West region of the Russian Federation requires new sources of feed with high yield and nutritional values. The purpose of the research is to study the possibility of sugar sorghum introduction into the region for forage use. The research was conducted in 2017-2020 in the conditions of the Novgorod region. On plots with an area of 10 m2 in the third decade of May sugar sorghum was sown: a hybrid of the first generation Silosnoe 88, the Galia variety, the Laretz line. The predecessors were potato (2017, 2018, 2020) and vetch and oat mix (2019). The ability of sugar sorghum to stop developing and hibernate in unfavorable weather conditions, resuming vegetation when the weather improves, has been established. Intensive plant growth was observed at the end of July-August with the average daily growth of 1.9-5.0 cm. By the end of August, the plant height reached 245-280 cm, the yield of green mass was 110 t/ha (hybrid Silosnoe 88), 139.2 t/ha (variety Galia), 136 t/ha (Laretz line). In the extreme conditions of 2017, the yield of sorghum green mass was 21 t/ha. The yield of dry matter (DM) from 1 ha reached 6.8-13.4 t/ha. The protein content in the DM was 8.4-11.5 %, the yield of feed units was 0.76-0.82 kg/kg, the output of exchange energy was 9.7-10.1 MJ/kg. Sugar sorghum has an ability to grow back after mowing; in the conditions of the Novgorod region, the yield of green mass from two mowing (end of July, August-September) was lower (23.3-46.7 t/ha) than from the one at the end of August-September (44.3-139.2 t/ha). The Laretz line vegetation phases began 5-27 days later than those of the Silosnoe 88 hybrid and Galiya variety. The growing season of sugar sorghum ended in the phase of “heading of panicles - flowering”. Thus, a high plasticity and adaptability of sorghum varieties to unfavorable climatic conditions of the zone and their prospects for use in forage production have been established.

The influence of after-effect of mineral fertilizers and lime on productivity of meadow clover 'Dymkovsky' with regard to the content of mobile phosphorus in the soil have been studied in a long stationary trial (established in 1971) on sod-podzolic soil developed on clay loam mantle in the Kirov region. The study was conducted in 2008-2018 on soil backgrounds with various acidity and mobile phosphorus sufficiency: without lime application (рН 3.68, Al 11-17 mg/100g of soil, P2O5 142-291 mg/kg of soil) and with lime application (рН 5.5, Al was not revealed, P2O5 120-232 mg/kg). In variants without application of phosphoric fertilizers the mobile phosphorus sufficiency was 77-84 mg/kg against acid background, and 66-89 mg/kg against limed background. The average yield of clover green mass in 2012 was 17.24 t/ha against acid background and 30.77 t/ha against limed background; the increase due to lime application was 78.4%, in 2018 – 13.0 t/ha, 28.3 t/ha, 118%, respectively. Reliable correlation links have been revealed between the degree of soil acidity (рН and Hh) and productivity of clover green mass, r = 0.76 and r = -0.79, respectively. The effect of the content of mobile phosphorus in the soil on clover productivity was insignificant. Weather conditions during the research influenced the content of crude protein in clover dry mass: in 2012 this indicator varied from 11.92 to 12.74% on the average, in 2018 ‒ from 17.47 to 19.88% against acid and limed background, respectively.
