The article characterizes the advantages of sudangrass, presents its comparative assessment, and gives recommendations for the cultivation of a new variety Evgeniya for seeds. Implementation of the program for the development of forage production in Russia and other countries implies not only the creation of new varieties but also the promotion of their introduction. This study aims to test the new variety Evgeniya of sudangrass and refine the cultivation techniques for obtaining high-quality seeds in the Volga region. For a period of 2 years, we studied the new promising variety, new lines that were obtained during interspecific, intraspecific, and intervarietal crossings carried out in different years, and new varieties of sudangrass recommended for cultivation in the region. The Yubileinaya 20 and Zonalskaya 6 varieties of sudangrass were used as standards. Field studies were carried out in 2017-2019. It was found that the new variety Evgeniya was characterized by high values of economically valuable traits. The variety had several biometric and biological features, such as thin stems and high yields, so we studied the influence of sowing methods and seeding rates not only on yield but on seed quality. To obtain the maximum yield of high-quality seeds, Evgeniya sudangrass must be sown with a seeding rate of 0.6-0.7 mln. viable seeds per hectare and row spacing of 30 cm.

Recent developments in cereal breeding for forage production have given the potential to greatly increase annual forage dry matter (DM) production. This paper reports on the findings from two cereal forage production trials on irrigated Canterbury land. Trial 1 studied the potential of a range of single and multi-grazed cereal forages over a 9 month period to produce high yields and quality from both grazing and whole-crop silage forage. Trial 2 studied the suitability of different cereal/ legume combinations for green-chop silage grown over a three month summer period. These two cereal forage systems, when combined in a 12 month period, produced in excess of 25 tonnes of high quality forage per hectare, almost double the DM production achieved using current perennial pasture based systems. Trial 1 showed no significant difference in the total DM produced by either single or multi-graze treatments. In Trial 2 pea/cereal combinations produced over 6 t DM/ha. Due to an earlier final harvest the multi-graze system is more easily combined with the summer crop and more likely to produce a lower cost and more sustainable forage system. Animal performance on forage produced in Trial 1 showed that dairy calves can grow well on cereal forages during winter. Keywords: cereal, feed supplements, forage, forage yield, legume, silage

The Horticulture Department of the University of Florence has been studying the pawpaw (Asimina triloba) since 1990 through collaboration with Italian fruit grower Domenico Montanari, who currently hosts the largest pawpaw orchard and variety collection in Italy. Research efforts are focused mainly on the development of new varieties and selections with desirable ornamental characteristics. New variety selection is based on high tree productivity, large fruit size, good organoleptic quality and improved fruit postharvest handling. The breeding program has resulted in 3,000 seedlings that are currently being evaluated in Tuscany, Italy. In addition to breeding efforts, 15 commercially available varieties were evaluated in replicated trials in 2000 and 2001, with selections characterized for vegetative, reproductive and pomological traits. In 2000 and 2001, the varieties `Prima 1216' and `Prolific' had high yields and should be suitable for production in Italian fruit-growing areas. Experiments to establish explants of pawpaw in culture were also performed testing a range of genotypes, disinfestation procedures, and methods to induce callus culture. Protocols for the propagation of pawpaw in vitro would offer many advantages for mass multiplication of desirable plants; however, the propagation of pawpaw in vitro has so far been met with limited success.

Abstract Variability of peanut (Arachis hypogaea L.) seedling spacing, and yield were compared for a conventional and a vacuum-type planter in field studies conducted in 1991 and 1992. Vacuum-type planters have an improved seed metering system and are considered to be more precise. This added precision may serve to compensate for lower than normal seeding rates. Seeding rates evaluated decreased in a step-wise manner from the normal range of 123 to 101 kg/ha, to a minimum of 34 kg/ha. Spacing between individual seedlings was measured after emergence. The occurrence of tomato spotted wilt (TSWV) and southern stem rot were also determined. In 1991 and across all seeding rates, variability in seedling spacing (i.e. standard deviation) was identical between the two planters. In 1992, at 3 of the five seeding rates (34,56, and 101 kg/ha) standard deviation was less with the vacuum planter. In both years yield and disease occurrence was influenced only by seeding rate, and was independent of planter type. TSWV was inversely related to seeding rate, the opposite relationship occurred with southern stem rot. Maximum yield was achieved with a seeding rate of 101 kg/ha.

The Middle Volga forest-steppe was subject to a comparative assessment to evaluate the effectiveness of combined insect-fungicidal pesticides as regulators of a phytosanitary state of farming ecosystems and yields of winter wheat. Insect-fungicidal pesticides used for pre-sowing treatment do not guarantee unconditional success, but they help to significantly reduce pest-induced losses and obtain safer grain produce. Regulated seeding rates showed that, once applied, combined dressing agents become slightly less biologically effective with overcrowding or thinning of crops. Dividend Supreme effectively reduced damage to shoots by Swedish flies, slightly worse than Celest Top. Celest Top and Dividend Supreme ensured stable suppression of root rot during the years of research. The winter wheat increasingly lodged when Celest Top and Dividend Supreme were used for seed dressing compared to the control (without dressing). Insect-fungicidal dressing agents increased the yield of winter wheat compared to the control and, at the same time, the risk of lodging. This effect was especially noticeable when Celest Top was used. It is recommended to use the combined Dividend Supreme and Celest Top pesticides for ensuring a stable phytosanitary situation and obtaining a high-quality harvest with a seeding rate of the target crop of 2-3 million seeds per 1 ha.

Barley productivity varies significantly in various agricultural areas, therefore, there should be conducted an ecological testing to identify varieties’ response to various soil and climatic conditions. That gives an opportunity to identify varieties adapted to specific soil and climatic conditions of a particular area or a region. The purpose of the current study was to conduct an ecological testing of winter barley varieties in the arid central part of theRepublicofKalmykiafor the subsequent identification of the most drought-tolerant, adaptable winter barley varieties, as well as to compare productivity of winter barley with that of spring barley in the arid conditions of the Kalmykia steppes. The study was carried out on the experimental plots of the Kalmyksky RIA named after M. B. Narmaev, a branch of the FSBSI “Pre-Caspian Agricultural Federal Research Center of the Russian Academy of Sciences” (PCAFRC) in 2018–2019. The objects of research were 9 winter barley varieties of various breeding institutions. The variety of winter barley “Erema” was a standard one, the only one from the entire set of studied varieties that has been included into the State List of Breeding Achievements of theRussian Federation, recommended for cultivation in theRepublicofKalmykia. The trials were laid in four sequences with a systematic arrangement of variants. The total area of the plot was60 m2, the registration plot was50 m2. The seeding rate was 350 pcs. Of germinating seeds per1 m2. The forecrop was winter wheat sown in a fallow land. The study has found that the productivity of the varieties “Timofei”, “Romans”, “Sprinter”, and “Molot” were significantly inferior to that of the standard variety. The productivity of the varieties “Espada”, “Kuzen”, “Vivat”, “Samson” were at the same level as of the standard variety. It should be noted that the maximum yield (4.13 t/ha) was produced by the new variety “Vivat” in 2018. The variety has an undoubted prospect to be cultivated in this region, as it is a facultative one according to the biological type of development, unlike the other studied varieties.

Under the conditions of the Trans-Urals the cultivation of varieties of field pea allows us to get high yields, not inferior to grain, provides high profitability and solves the problem of protein in animal husbandry. Its inclusion in the crop rotation contributes to the improvement of soil fertility, yield and product quality of subsequent crops. Pea seeds depending on the variety and cultivation conditions contain (in % per dry matter): 9–15 water, 18–35 protein, 46–60 nitrogen-free extractives (including 20–50 % starch, 4–10 % sugars), 0,6–1,5 fat, 2–10 fiber, 2–4 ash. The purpose of the research was to determine the economic and biological value of varieties of field pea and the influence of biotic and abiotic factors on crop yield under the conditions of the Trans-Urals. According to the results of three years of study a good level of yield was noted in the varieties recommended for cultivation in the Ural region, which includes the Kurgan region: Aksaysky Usaty 55–2,47 t/ha; Agrointel – 1,88 t/ha, Zauralsky 3–2,12 t/ha, Samarius – 2,40 t/ha. Among the new varieties the high yield was shown by the varieties Kulon – 2,75 t/ha, Yamal 305–1,94 t/ha, Chevron – 1,84 t/ha. The increase in the seed yield of pea varieties with the use of urea (N₃₀) was noted for all the studied varieties. So, for example, for Sibur 2 variety by 1,11 times, for Aksaysky Usaty 55 and Samat varieties by 1,12, for Samarius variety by 1,15 times. The use of urea and double superphosphate (N₃₀P₃₀) to obtain the maximum yield for the studied varieties of peas allowed to increase the yield for the variety Aksaysky Usaty 55 by 1,18 times, Samat and Sibur 2 by 1,17, Samarius by 1,2 times.

Биоклиматический потенциал Псковской области позволяет ежегодно получать качественные семена практически всех видов многолетних злаковых и некоторых видов бобовых трав. Первостепенная роль в производстве кормов принадлежит сеянным травам как в полевом (площадь земель составляет 182,8 тыс. га), так и луговом кормопроизводстве (естественные сенокосы (230 тыс. га) и пастбищам (244 тыс. га). Основными направлениями в повышении продуктивности и улучшении качества кормовой базы, на наш взгляд, должны стать новые сорта многолетних трав, возделывание которых ведется с использованием современных агротехнологий. Селекционная работа по выведению новых сортов козлятника восточного ведется в 7 питомниках на полях ФГБНУ ФНЦ ЛК Обособленного подразделения г. Пскова. На каждом этапе селекционного процесса, в каждом питомнике выделены лучшие образцы по ряду хозяйственно ценных и морфологических признаков. На заключительной многолетней стадии, в питомнике конкурсного испытания высеяны сортообразцы, которые выделены из различных питомников с сохранением отличительных признаков, морфологических или хозяйственно-ценных. Селекционерами института создан новый сорт козлятника восточного Талисман (сортообразец №24), превышающий по продуктивности и качеству сорт-стандарт Кривич на 7-10%, в среднем за годы испытаний (5 лет) урожайность зеленой массы составила 38,1 т/га, сухой массы – 9,7 т/га, что выше стандарта на 11%. Семенная продуктивность в среднем за 5 лет была на уровне 4,5 ц/га. Содержание сырого протеина в сухом веществе данного сорта было на уровне от 20 до 22,0%. Выход сырого протеина с урожаем составил 1,9 т/га. The bioclimatic potential of the Pskov region makes it possible to annually obtain high-quality seeds of almost all types of perennial grasses and some types of legumes. The main role in feed production belongs to sown grasses both in the field (the land area is 182.8 thousand hectares) and in meadow forage production (natural hayfields (230 thousand hectares) and pastures (244 thousand hectares). In our opinion, the main directions for increasing productivity and improving the quality of the feed base should be new varieties of perennial grasses that are cultivated using modern agricultural technologies. Breeding work on breeding new varieties of Eastern goat is carried out in 7 nurseries in the fields of the Federal state budgetary scientific center of the LPR, a separate division, Pskov. At each stage of the breeding process, each nursery selects the best samples for a number of economically valuable and morphological characteristics. At the final multiyear stage, in the nursery of competitive tests, varietal samples were sown, which were isolated from various nurseries with the preservation of distinctive features, morphological or economically valuable. Breeders of the Institute have created a new variety of Eastern talisman goat (variety type No. 24), which exceeds the productivity and quality of the standard Krivich by 7-10% on average, over the years of testing (5 years), the yield of green mass was 38.1 t/ha, dry mass – 9.7 t/ha, which is 11% higher than the standard. Seed productivity on average for 5 years was at the level of 4.5 c/ha. The content of crude protein in the dry matter of this class was at the level of 20 to 22.0%. The yield of crude protein from this crop was 1.9 t/ha.

In terms of differentiation of agricultural enterprises by the level of intensification of grain production it is necessary to cultivate varieties that are most adapted and cost-effective for specific levels of technologies of growing spring wheat. This is confirmed by the ecological variety testing, which was carried out in different soil - climatic and technological conditions. In the Vladimir niiskh on gray forest soils under normal technology, the new variety of mA’am was characterized by the highest yield, resistance to lodging and disease. In the competitive variety testing on average for 10 years, he provided a yield of 37.7 C / ha (higher than the best studied in the experience of varieties by 5.9-10.3 C/ha) with resistance to lodging 8.4 points on a 9-point scale. The maximum yield varieties in 2009 was 62.0 q/ha. During the last 5 years of competitive variety trials the most stable and productive years was a kind of heater, which on average for 2013-2017 exceeded the grade’am 4.6 t/ha in the same agricultural background. Among studied varieties of spring wheat the highest yields provided a variety Rook, cultivated on intensive technology: high soil fertility in the Republic of Belarus yields reached 99,0 kg/ha in 2013, and in Yaroslavl, NIIZK - 80,0 kg/ha in 2017 In the Vladimir research Institute of agriculture at high doses of fertilizer, but without the protection of plants from diseases, pests and lodging in 2017 received a yield grade of 73.0 kg/ha.

High seed quality is required to obtain optimal plant stands and to achieve maximum yield potential. Onion seeds are commonly coated and treated with an insecticide and fungicide to control early season insects and diseases. The seed treatments may cause phytotoxicity in standard germination tests, and thus reduce the percent germination of a seed lot. The objective of this study was to examine the effect of seed quality on seed storage, stand establishment and yield. Two seed lots of two long-day onion varieties were pelleted and treated with the seed treatments Trigard and Pro-Gro. Standard germination and saturated salt aging tests were performed on each seed lot, indicating a high and lower quality seed lot for each variety. Aging was conducted by equilibrating pelleted seeds at 35% relative humidity and aging at 25 °C for up to 12 months. Aging decreased germination with time, especially for the lower quality lots. Field studies were conducted in two locations in upstate New York. The plant stand was greater in the high compared to the lower quality lots in both varieties at both locations. Yield was reduced in the lower quality than high quality lot; however, the response differed by variety and location. Overall, the initial seed quality had an impact on seed storagability, stand establishment and yield.
