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 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.

Исследования проведены в 2016–2018 годах на полях Научно-исследовательского института ветеринарии Восточной Сибири – филиала СФНЦА РАН, расположенных в Ингодинско-Читинской лесостепи Забайкалья. В статье представлены результаты полевых и лабораторных исследований по возделыванию мятликовых традиционных культур в одновидовых и бинарных посевах с кормовыми бобами в кормопроизводстве Забайкалья. Исследования выполнены на лугово-чернозёмной мучнисто-карбонатной почве. Дана оценка кормовым мятликовым культурам и бобам по адаптивности к условиям выращивания, показаны их хозяйственно ценные признаки. Установлена возможность повышения продуктивности и питательной ценности кормовых агроценозов путём использования кормовых бобов в бинарных посевах с мятликовыми культурами. По продуктивности и питательной ценности двухкомпонентные посевы превосходили одновидовые агроценозы мятликовых культур по зелёной массе в 2,3–2,7 раза, переваримому протеину — в 1,7–1,8 раза. В бинарных посевах наилучшие результаты обеспечили посевы ячменя и овса с кормовыми бобами, где урожайность зелёной массы составила 34,9–37,2 т/га, сухого вещества — 5,2–5,4 т/га, кормовых единиц — 4,68–4,90 т/га, переваримого протеина — 646–662 кг/га, обменной энергии — 54,6–57,2 ГДж/га, обеспеченность 1 корм. ед. переваримым протеином — 135–138 г. Бинарные посевы ячменя и овса с кормовыми бобами увеличили продуктивность в сравнении с одновидовыми посевами по сбору кормовых единиц в 1,6–1,9 раза, переваримому протеину — в 2,3–2,7 раза, валовой энергии — в 1,5–1,7 раза. По отношению к засухе наиболее устойчивыми культурами были ячмень (4,9 балла), яровая рожь (4,6), кормовые бобы (4,8 балла), менее устойчивым был овёс (3,8 балла). Все культуры, за исключением яровой ржи, оказались устойчивы к полеганию (5 баллов). Отмечено отсутствие поражённости вредителями и болезнями у мятликовых и бобовых. This article reports on gramineous cultivation as monoculture or binary sowing with field beans in Transbaikal conducted in 2016–2018. The experiment tested crop stress resistance and economically important traits. Seeding field beans with gramineous improved forage yield and nutritional value. Binary sowings exceeded pure ecosystems of gramineous by 2.3–2.7 times in green mass and 1.7–1.8 times — in digestible protein. Ecosystems of barley and oats with field beans performed the best, producing 34.9–37.2 t ha-1 of green mass, 5.2–5.4 t ha-1 of dry matter, 4.68–4.90 t ha-1 of feed units, 646–662 kg ha-1 of digestible protein, 54.6–57.2 GJ ha-1 of exchange energy, and 135–138 g of digestible protein per feed unit. Binary sowings of barley and oats with field beans exceeded monocultures by 1.6–1.9 times in feed units, 2.3–2.7 times — in digestible protein, 1.5–1.7 times — in gross energy. Based on a 0–5 scale, barley (4.9), spring rye (4.6), and field beans (4.8) tolerated drought well while oats were less resistant (3.8). Only rye was susceptible to lodging. Gramineous and legumes showed no disease symptoms or damage caused by pests.

The research was aimed at scientific substantiation of the possibility to reach high productivity of fodder galega due to the use of plant protection products and the Albite growth regulator, and their effect on the fodder quality. To achieve this goal, the effect of these factors on the yield of green mass and dry matter, on the collection of gross energy, metabolizable energy of feed units, and digestible protein was studied in 2012 – 2014 during the field experiments and in laboratory studies. As a result of the studies, it has been found that galega had the greatest yield of dry matter, metabolizable energy, energy feed units, and digestible protein on the nonpesticide background with plants double sprayed with Albite, and on the pesticide background — in the phase of spring aftergrowing and budding. Prevailing accumulation of crude protein and calcium in the green mass was on the nonpesticide background with double spraying with Albite; of crude fiber — on the pesticide background in the phase of spring aftergrowing; of crude ash — in the phase of seedling + budding; and of crude fat — without introducing any growth regulator. Plant protection products and Albite did not significantly increase the concentration of nitrogen-free extractives (NFE) and phosphorus. The studied factors did not affect the content of gross energy (GE), metabolizable energy (ME) and energy feed units (EFU) in 1 kg of dry matter of galega green mass, and did not increase the concentration of digestible protein in EFU.

Thus the breeding process is aimed to develop first generation hybrids with a strong potential of productivity and quality of green mass and silage. The purpose of the work is to study heritability and heterosis of the quantitative traits of sweet sorghum hybrids F1 obtained on a sterile basis. The study was conducted in 2013-2015 on the lines with cytoplasmic male sterility (‘A-63’, ‘Knyazhna’, ‘APV-1115), the varieties (‘Listvenit’, ‘Severnoe 44’, ‘Zernogradskoe 454’, ‘Stavropolskoe 36’, ‘Galiya’ and ‘Larets’) and the hybrids. The inheritance of green mass productivity and absolutely dry matter, the length of a vegetation period, plant height and leaf formation (foliage), protein content in dry matter of the hybrids occurred according to the type of dominance and overdominance. It has been determined that while choosing the parental forms for hybridization it’s essential to select the forms with differences in the vegetation period of 4-6 days to avoid the dominance of late maturity. The height pollinator increase results in the hybrid height increase and large heterosis. It’s necessary to select the parental forms with maximum foliage to improve leaf formation in the hybrids.
