Tuber Flesh

Background. Resistance of raw and boiled tuber flesh to darkening when potato is processed into potato-based products or consumed directly is an important requirement for new potato cultivars. Identification of hybrids resistant to tuber flesh darkening would contribute immensely to future breeding work.Materials and methods. Parent forms and hybrid progeny of potato were tested for five years (2016–2020) in Kirov Province using the methods and technologies approved for potato breeding process. The progeny of 10 cultivars used as pollinators was analyzed.Results and conclusions. Cultivars with high levels of resistance to the darkening of raw tuber flesh were selected in the collection nursery. A total of 62 accessions (or 24%) out of 256 were identified for the absence of darkening or only small traces thereof (8 points) in raw tubers. Medium and strong darkening of the flesh (4–5 points) was recorded for 45 accessions. Analyzing the progeny of pollinator cultivars showed an increased occurrence of hybrids resistant to tuber flesh darkening in the progeny of cv. ‘Manifest’: 71% of the studied hybrids had non-darkening flesh (9 points). Manifestation of tuber flesh darkening was found to depend on weather conditions during the growing season: the higher was the air temperature, the weaker was the darkening of raw tuber flesh, but when the soil moisture during tuberization was high, tuber flesh became more darkened. A statistically significant relationship was observed between the darkening of boiled tubers and the content of crude protein (r = 0.74) and vitamin C (r = 0.79). Hybrid 179-10 was identified for high productivity (32.5 t/ha) and crude protein content (1.54%), while the highest resistance to the darkening of raw and boiled potato tubers was registered in hybrid 72-13.

The purpose of the research was to study the effect of planting time on the formation of productivity of Hungarian sainfoin when grown for green forage. Methods are field, laboratory, statistical, correlation and regression relationships. Research results. It is established that under uneven humidity and high temperature regime in the year of sowing, Hungarian sainfoin formed two yields under spring planting date and one yield under summer planting date. In the second and third years of growth, no significant effect of the planting date on the stages of organogenesis of Hungarian sainfoin was found, where the maturity of the herbage was reached simultaneously. Productivity of Hungarian sainfoin was only conditioned by hydrothermal conditions, where the yield of green mass averaged 45.9—49.6 t/ha with crude protein content of 1.58—1.73 t/ha. At the same time, the highest dry matter yield of 10.25 t/ha and crude protein of 1.73 t/ha was provided by agrophytocenosis when sown on April 12. The productivity index of Hungarian sainfoin in the first year of life was determined, where the highest indicator was obtained during the early spring sowing period (29.04) – 7.85 kg/ha of dry matter per 1 hour of light day, whereas for the recommended summer sowing period was 1.13 kg/ha, or 6.9 times lower. The correlation equation between dry matter output, duration of daylight and the sum of precipitation from full shoots to the beginning of flowering in the first year of life is described. It is found that with increase of precipitation by 1 mm the dry matter output increases by 1.53 % and there is a tendency increase with increasing the length of daylight by 1 minute. Conclusions. It has been established that on gray forest soils of the right-bank Forest-Steppe, over two years of intensive use of the grass stand, regardless of hydrothermal conditions, Hungarian saifoin provided a stable forage productivity when sown in spring. Thus, dry matter yield was 9.38—10.25 t/ha with crude protein content of 1.58—1.73 t/ha. In particular, as for summer planting date, July 20 appeared to be the most effective planting date, which provided dry matter yield of 9.78 t/ha with crude protein content of 1.61 t/ha.

Sowing is one of the most important agronomic measures in soybean cultivation. However, today in Ukraine there is no universal approach to defining the optimal sowing time. Some researchers assert that one should rely on the calendar period of sowing; other specialists argue that the spring features should be the primary determinant; the third group think that the thermal conditions at a depth of 10 cm is the main factor; and according to the fourth opinion, soil and clime characteristics are critical. The hydrothermal conditions in the years of our research deviated significantly from the annual average. Thus, the hydrothermal coefficient during the soybean growing period in 2018 was 0.34, and in 2019 it was 0.52, indicating that the cultivation conditions were arid (0.5 <HTC <0.9). The experiments showed a clear downward trend in the growing period length and upward trends in the field germinability of seeds and leaf surface area when soybean was sown in soil warmed to 14-16оС on May 10-15. In this case, the biometric parameters of soybean plants improved, and the yield increased by 0.15-0.16 t/ha. Keywords: soybean varieties, weather conditions, sowing time, field germinability of seeds, plant survival, photosynthetic and symbiotic activities of plants, grain yield.

Goal. To establish the level of productive potential and economic efficiency of growing restored meadow grasslands on sloping lands with organic production of fodder raw materials. Methods. Field and laboratory research in feed production, hypotheses, dialectical, synthesis and analysis, induction, statistical. Results. Scientific and technological bases of growing perennial grasses on sloping lands with organic fodder production have been formed, which envisage introduction of a set of measures not only for production of ecologically safe fodder for animals with maximum use of biological intensification factors, but also preservation of environment, including soils and biodiversity. Using the index of coenotic activity of each species in mixed agrophytocenoses, a strategy for the development of perennial grasses depending on the level of influencing factors (method of creation, fertilizer system and mode of use) was established. Dominant (Onobrychs arenaria, Medicago sativa, Festuca arundinacea) and patient (Lotus corniculatus, Bromus inermis, Bromus riparius) species are identified for the artificial multicomponent agrophytocenosis. It is established that for organic meadow cultivation on sloping lands, preference should be given to perennial legumes, which without additional energy resources provide output from the forage area of bulky feed with a dry matter yield in the range of 13.7-15.1 t/ha with crude protein content of 19.8-20.3%, metabolic energy 9.4-9.7 MJ/kg, and demonstrate a break-even level in the second year of use. Conclusions. During the research the technology has been developed for restoration of the Forest-Steppe degraded meadow lands for organic fodder production, which will provide a 45.2-58.2 t/ha grass fodder yield of green mass, 12.8-14.3 t/ha dr matter with 17.8-18.3% crude protein content, 9.1-9.2 MJ/kg metabolic energy with energy coefficient indicators at the level of 3.40-5.15, 1.78-2.62 energy efficiency coefficients (Kee). The cost recovery is UAH 1.73-1.85, and the level of profitability is 98-112%. The development allows 2-3 times increase in productivity of degraded grasslands.

Due to the lack of irrigation, the question of replacing soybean with an equivalent crop in the context of nutritional value and adaptation to the weather conditions of Crimea arises. One of such crops can be white lupine (Lupinus albus L.). The purpose of the research was twofold: assess L. albus productivity and crude protein content in grain; identify the most promising varieties and breeding numbers of white lupine under conditions of the steppe Crimea. In 2016-2018, the research was carried out on the experimental field of the Research Institute of Agriculture of Crimea according to the B.A. Dospekhov methods of field research and methodology of the State variety testing of agricultural crops. We studied the influence of bioclimatic conditions of the steppe Crimea on the growth, development, grain yield formation and protein content of four varieties (‘Michurinsky’, ‘Alyi Parus’ (standard), ‘Dega’ and ‘Desnyansky 2’) and four promising breeding numbers (‘CH-1022-09’, ‘CH-1677-10’, ‘CH-1397-10’ and ‘CH-6-11’). A wide diversity of weather conditions during the years of research made it possible to evaluate the samples in favorable and stressful conditions. In drier years, the growing season lasted 93–97 days because of the reduction in interphase periods; in milder ones it was101 days. The results in grain yield have been mixed: from 0.48 to 1.45 t/ha in 2016; from 0.35 to 0.56 t/ha in 2017; from 0.39 to 0.54 t/ha in 2018. On average, over a three-year study, breeding numbers ‘CH-1022-09’ and ‘CH-1677-10’ were the most productive. Their yield was 0.65 and 0.81 t/ha, respectively. In 2017, crude protein content varied from 24.02 to 28.49%; in 2018 – from 26.05 to 31.1%. On average, over the years of study, the highest protein content was typical for the varieties ‘Alyi Parus’ (29.30%) and ‘Michurinsky’ (29.03%). Breeding numbers ‘CH-1022-09’ and ‘CH-1677-10’ were distinguished by the highest indicators of productivity and yield; in terms of crude protein content, varieties ‘Alyi Parus’ and ‘Michurinsky’ were the best. Consequently, they are the ones that are recommended for cultivation.

За останні роки на Полтавщині в погодних умовах суттєво змінилися температурний і водний ре-жими. Протягом веґетаційного періоду 2008–2012 років спостерігалося підвищення середньомісячної температури на 1,8 0С, що більше на 13,1 % від середньої багаторічної норми та зменшення кіль-кості опадів на 72,5 мм, або на 23,2 %. Важлива роль у підвищенні продуктивності сільськогоспо-дарських культур належить добривам. В умовах значного подорожчання енерґоносіїв та агрохімі-катів позакореневі підживлення комплексними водорозчинними добривами стають особливо ак-туальними. Застосування цього агрозаходу в умо-вах Лівобережного Лісостепу України за нестабі-льного зволоження дає можливість підвищити продуктивність пшениці озимої на 25,8 %, кукуру-дзи зернової на 12,7 %, буряків цукрових на 15,7 % і суттєво поліпшити якість продукції. Temperature and water regimes have changed over the past few years in Poltava in the weather conditions. So during the growing period of 2008–2012, an increase in the average temperature of 1.8 0C, an increase of 13.1% from the average long-term rates and a decrease in rainfall at 72.5 mm, or 23.2% was observed. The leading role in increasing the productivity of crops belongs to fertilizers. With the significant rise in price of energy and agrochemicals, foliar feeding by complex water-soluble fertilizers becomes particularly relevant. The use of this agro method in the left-bank forest-steppe zone of Ukraine with not persistent moisture makes it possible to increase the productivity of winter wheat by 25.8%, corn grain by 12.7%, sugar beet by 15.7%, and significantly improve the quality of products.

Відображено вплив елементів інтенсифікації вирощування на тривалість проходження міжфазних періодів ріпаку ярого в умовах Правобережного Лісостепу. Відмічено, що вивчені в досліді фактори сприяли різному за тривалістю проходженню фаз росту та розвитку рослин ріпаку. За результатами проведених досліджень з'ясовано, що в разі внесення азотних мінеральних добрив період веґетації збільшувався в усіх варіантах, проте залежав від виду добрив. У свою чергу на тривалість періоду веґетації досліджуваних сортів та гібридів ріпаку ярого вплинули і  погодні умови років проведення досліджень. Встановлено, що оптимізація режиму живлення за рахунок внесення різних видів азотних добрив (аміачна селітра, сульфат амонію, карбамід) забезпечує більш повну реалізацію потенціалу продуктивності  рослин. We display effect of intensification elements of the cultivation on the length of the passage of spring rape interfacial periods in conditions of Right-Bank Forest-Steppe. It is noted that examined factors promoted different contribution of the passage phases of growth and development of plants rape in the experiment. According to the results of the study we found that if we put nitrogen fertilizer the growing period has increased in all versions, however, it was dependent on the type of fertilizer. In turn, the length of the growing season studied varieties and hybrids of spring rape was influenced by weather conditions and years of research. We found that optimization of state of nutrition by putting different types of nitrogen fertilizer (ammonium nitrate, ammonium sulfate, urea) provides a full realization of the potential of productivity of plants.

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.

Goal. The purpose of the research was to determine the influence of meteorological factors on potato yield in the conditions of the Right Bank Forest-steppe of Ukraine. Methods.Field, analytical and statistical. Results.It was established that among the mid-range varieties Divo stands out with a yield of 42.3 t/ha, Malin white – 39.8 t/ha, and Legend – 37.1 t/ ha. The most favourable weather and climatic conditions for the production of potato tubers were for the Divo 2011 variety with a yield of 45.9 t/ha and 2013 – 45.1 t/ha. For the Legenda variety 2016, the yield of potato tubers is 40.6 t/ha and 2017 – 43.2 t/ha. Malin White 2013 is 41.4 t/ha and 2017 42.1 t/ha. The average varieties of potatoes showed a slightly lower yield on average over the years of research. However, among the varieties is allocated Nadiyna – 40.3 t/ha, Slovyanka – 37.2 t/ ha and Vera 33.8 t/ha. Among the years, the most high-yielding for the Vera variety was 2016 with a yield of 36.6 t/ha and 2017 year – 37.8 t/ha. Varieties Slovyanka and Nadiyna 2011 and 2012 with yields of 42.6 and 44.3 t/ha and 46.5 and 45.3 t/ha, respectively. Characterizing the yield of potato tubers of medium-late varieties over the years of research, there was a decrease in this indicator compared with medium-early and middle-aged varieties. However, the high yield of the varieties of Dar is allocated – 40.0 t/ha, Alladin – 33.6 t/ha and Oxamit 31.3 t/ha. Among the years, the most favourable ones were: for Oxamit and Alladin – 2011 – 33.5 and 36.5 t/ha, and 2017 – 34.1 and 36.4 t/ha, respectively. Favourable years for harvesting varieties were 2011 and 2012 with yields of 45.7 and 45.8 t/ha. Thus, the highest yield of potato tubers on average over the years of studies of medium-early varieties of 41.2-43.3 t / ha were provided by weather conditions of 2011 and 2017 years, medium-ripe varieties 41.0-41.1 - 2012 and 2011, medium- late 37,6-38,5 t / ha - 2012 and 2011, respectively.
