<p>The aim of the study was to compare yields and nutritional value of selected species and cultivars of forage grasses under the optimal moisture conditions and long-term drought stress. The regenerative capacity of plants after dehydration was also assessed. The pot experiment was conducted in years 2009–2010 in IUNG-PIB’s greenhouse in Puławy, Poland. Nine cultivars of four species: <em>Dactylis glomerata</em> (‘Amera’, ‘Minora’), <em>Festuca pratensis</em> (‘Skra’, ‘Fantazja’), <em>Festulolium braunii</em> (‘Felopa’, ‘Agula’, ‘Sulino’), and <em>Lolium multiflorum</em> (‘Gisel’, ‘Lotos’) were investigated in well-watered conditions (70% field water capacity – FWC) and under a long-term drought stress (40% FWC).</p><p>The study showed that stress caused by soil moisture deficiency significantly reduced yields of <em>D. glomerata</em>, <em>F. pratensis</em>, <em>F. braunii</em>, and <em>L. multiflorum</em>. The total yield of dry matter under stress conditions was about 31% lower, compared to the performance achieved on the optimally moisturized treatment. The smallest reduction in dry matter yield under the conditions of water deficit was recorded for <em>D. glomerata</em>, which makes it the most resistant to stress, followed by <em>F. pratensis</em>. The resistance of <em>F. braunii</em> and <em>L. multiflorum</em> to stress was similar and significantly lower. There was a various response of different grasses to the water stress. On the basis of the value of the DSI (drought susceptibility index), the tested cultivars were ranked depending on the sensitivity to drought, starting with the most resistant cultivar: ‘Minora’, ‘Skra’, ‘Fantazja’, ‘Amera’, ‘Sulino’, ‘Agula’, ‘Gisel’, ‘Lotos’, and ‘Felopa’. The digestibility of dry matter and nutrient value of the grasses depended on both the level of soil moisture and grass species. Under the water stress, the digestibility and protein value increased compared to the control objects. <em>Lolium multiflorum</em> and <em>F. braunii</em> had the best nutritional value, while <em>D. glomerata</em> – the weakest.</p>

Plant breeders aim to develop cultivars of perennial ryegrass Lolium perenne L., (PRG) that better support New Zealand farmers through improved genetic potential for key traits such as seasonal dry matter yield. Hybrid vigour (heterosis) may be one way plant breeders can increase dry matter yields, and potentially lift the long term rate of genetic gain. We report evaluation of PRG full-sibling progeny for heterosis expressed under grazing. Parents were randomly sampled from sixteen cultivars, and for each cultivar combination within mid-season and late season classes, six pair crosses were made. In 2013, replicated single row trials of parent cultivar samples and progeny were sown at two sites near Palmerston North. For 2 years, prior to each grazing, growth score (GS) data were recorded to estimate dry matter yield of each plot. Progeny GS relative to parent average GS (mid-parent heterosis, MPH), and better parent GS (high-parent heterosis, HPH) were calculated on the basis of the mean GS over years and sites.

The results of research into the creation of a new cultivar of spring common vetch Obskaya 16 are presented. The work was carried out in the period 2014-2017. The goal was set to create a new earlyripening variety with а high fodder and seed productivity, high protein content, and an even ripening of seeds. The vetch cultivar Obskaya 16 was created by the method of hybridization on the basis of genetically different and ecologically-distant genotypes with subsequent multiple selection according to the specified parameters from the Kamalinskaya 611 × Novosibirskskaya hybrid populations. The vetch cultivar Obskaya 16 combines early ripeness with high fodder and seed productivity. The length of the growing season of the new cultivar is, on average, 81 days, which allows for the production of certified seeds annually. During all the years of testing in breeding nurseries, the new cultivar surpassed the standard Kamalinskaya 611 in green mass by 41%, in dry matter by 40%, and in grain by 27%. This cultivar is of mowing type, its average seed yield is 2.43 t/ha, green mass 28 t/ha, dry matter – 5.82 t/ha. The main economic and valuable characteristics of the Obskaya 16 cultivar are as follows: the height of the stem is 85-120 cm, the number of internodes is 19-25, the height of attachment of the lower seed pods is 78 cm. The average number of seed pods per plant is 24, the maximum is 46, the average number of seeds per a seed pod is 7-8. The mass of 1000 seeds is 72.6 g. The colour of the seed coat is mainly black velvet (92%) and brown (8%). Crude protein content is 25.3–30.5%. In 2016 the cultivar of spring common vetch was passed to the state variety testing under the name Obskaya 16. The newly created cultivar surpasses the previously recognized varieties in the region by early ripeness, fodder and seed productivity, as well as high fodder quality.

Maize forage is poor in protein content which shows its low quality and nutritive value. Regarding to high feed costs of protein supplementations, legumes can be used in livestock nutrition for their high protein content and, thus, providing cost savings. Since legumes have low dry matter yield, acceptable forage yield and quality can obtained from intercropping cereals and legumes compared with their sole crops. In this study, maize (Zea mays L.) and climbing bean (Phaseolus vulgaris L.) were intercropped in different sowing densities and their monocropping equivalents were tested to determine the best intercropping system on forage yield and quality. Maize was cultivated alone (75 000 plants ha-1) and intercropped with bean as follows: 75 000 plants ha-1 of maize and 37 500 plants ha-1 of bean (MB1), 75 000 plants ha-1 of maize and 50 000 plants ha-1 of bean (MB2) and 75 000 plants ha-1 of maize and 75 000 plants ha-1 of bean (MB3), in rows alternating with maize. The highest dry matter yield was produced by MB3 (20.9 t ha-1), and the lowest by maize (16.9 t ha-1). All intercropped systems had higher crude protein contents, MB1 (92 g kg-1 DM), MB2 (99 g kg-1 DM) and MB3 (110 g kg-1 DM), than the maize (77 g kg-1 DM). Intercropping of maize with bean reduced neutral and acid detergent fiber, resulting in increased forage digestibility. Therefore, maize intercropping with bean could substantially increase forage quantity and quality, and decrease requirements for protein supplements as compared with maize.

Despite the gradual increase in livestock feed demands, the supply faces enormous challenges due to extreme climatic conditions. As the presence of these climatic condition has the potential to affect the yield of sorghum-sudangrass hybrid (SSH), understanding the yield variation in relation to the climatic conditions provides the ability to come up with proper mitigation strategies. This study was designed to detect the effect of climatic factors on the long-term dry matter yield (DMY) trend of SSH using time series analysis in the Republic of Korea. The collected data consisted of DMY, seeding-harvesting dates, the location where the cultivation took place, cultivars, and climatic factors related to cultivation of SSH. Based on the assumption of normality, the final data set (n = 420) was generated after outliers had been removed using Box-plot analysis. To evaluate the seasonality of DMY, an augmented Dickey Fuller (ADF) test and a correlogram of Autocorrelation Function (ACF) were used. Prior to detecting the effect of climatic factors on the DMY trend, the Autoregressive Integrated Moving Average (ARIMA) model was fitted to non-seasonal DMY series, and ARIMA (2, 1, 1) was found to be the optimal model to describe the long-term DMY trend of SSH. ARIMA with climatic factors (ARIMAX) detected significance (p < 0.05) of Seeding-Harvesting Precipitation Amount (SHPA) and Seeding-Harvesting Accumulated Temperature (SHAMT) on DMY trend. This does not mean that the average temperature and duration of exposure to sunshine do not affect the growth and development of SSH. The result underlines the impact of the precipitation model as a major factor for the seasonality of long-term DMY of SSH in the Republic of Korea.

Одна из важнейших задач кормопроизводства — разработка агротехники для получения сбалансированных кормов высокого качества. Изучено влияние норм высева компонентов травосмеси, фона минерального питания и сроков уборки на продуктивность и питательность кормовой массы совместных посевов люцерны изменчивой и костреца безостого. Исследования проводили в 2017–2019 годах в Пензенской области. Годы пользования травостоями характеризовались острозасушливыми (2018 год) и засушливыми (2019 год) условиями вегетационных периодов, гидротермический коэффициент в среднем за вегетационный период составил 0,4 и 0,7 по годам соответственно. В исследованиях использовались сорта люцерны изменчивой (Medicago × varia Mart.) Дарья, костреца безостого (Bromopsis inermis (Leyss.) Holub) Удалец. В среднем за 2018–2019 годы выявлены достоверные различия по урожайности зелёной массы, сбору сухого вещества по каждому из изучаемых факторов. Более высокие показатели получены при высеве люцерны с 70%-ной, костреца — с 40%-ной нормой высева: урожайность зелёной массы — 53,6 т/га, сухого вещества — 11,87 т/га. Внесение P60K90 и N45P60K90 увеличило выход зелёной массы по сравнению с контролем на 9,5–16,2%, сухого вещества — на 7,8–12,3%. Уборка в фазу бутонизации люцерны обеспечила получение 55,0 т/га зелёной массы и 12,05 т/га сухого вещества, или на 31,9 и 22,0% больше, чем в фазу цветения. По питательной ценности сухого вещества выделились скошенные в фазу бутонизации смеси с большим содержанием люцерны (70+40%) при внесении минеральных удобрений. One of the most important tasks of feed production is the development of agricultural technology to obtain balanced high quality feed. The influence of seeding rates, the mineral nutrition and the harvesting time on the productivity and nutritional value of the alfalfa-smooth brome forage mass was studied. The investigations were carried out in the Penza region in 2017–2019. The growing season conditions were severely arid (2018) and arid (2019), the average hydrothermal coefficients per growing season were 0.4 and 0.7 over the years, respectively. The varieties of bastard alfalfa (Medicago × varia Mart.) “Daria” and smooth brome (Bromopsis inermis (Leyss.) Holub) “Udalets” were used for the study. On average for 2018–2019, the yield of green mass and of dry matter varied significantly for each of the studied factors. Higher results were obtained under alfalfa and smooth brome seeding rates of 70 and 40%, respectively: the yield of green mass was 53.6 t ha-1, dry matter — 11.87 t ha-1. The application of P60K90 and N45P60K90 increased the yield of green mass by 9.5–16.2%, dry matter — by 7.8–12.3%. Harvesting alfalfa at budding stage provided 55.0 t ha-1 of green mass and 12.05 t ha-1 of dry matter, or 31.9 and 22.0% more than at the flowering stage. Mixtures with high alfalfa content (70 + 40%) had dry matter of better quality cut at budding stage under mineral fertilization.
