Main Components

The industrial cultivation of beans is predertmined by economic and agronomic attractiveness of the crop. However, the selection of varieties is among the main components of technology, which determine the growth of efciency of beans production. The maximum level of cultivars' potential realization largely depends on the duration of the interphase and vegetation periods of common beans. Therefore, the aim of the research was to study the duration of the growing season and grain productivity of common beans, depending on varietal characteristics and seed inoculation. According to the research results, it was found that on the control (bean variety Bukovynka without seed inoculation) the duration of the growing season was 87 days. The growing season was shorter in varieties Halaktyka and Slaviia – 80 and 84 days, respectively. The growing season for varieties Nata and Otrada was longer than the control cultivar Bukovynka – 89 and 92 days, respectively. And the longest growing season for the control fertilization was in the Ros variety – 94 days. Seed inoculation with Rizoaktiv continued the duration of the growing season of the bean variety Slaviia for one day, Bukovynka, Ros, Nata for two days, Otrada for three days. Yield is the most important property of a variety. In our studies, the yield of beans increases from 0.65 to 2.87 t/ha, depending on the weather conditions of the year of cultivation, varietal characteristics and pre-sowing inoculation of seeds. The highest increase in grain yield from seed inoculation was obtained in 2018, which was more favorable in terms of moisture. Thus, the largest increase in grain yield from the use of Rizoactive was provided by the varieties Halaktyka (0.14 t/ha or 5.7 %), Ros (0.15 t/ha or 5.5 %) and Otrada (0.22 t/ha or 7.7 %). On average, according to the results of research conducted in 2018–2020, it was found that inoculation of bean seeds with Rizoactive, depending on the variety, provided an increase in grain yield from 2.4 to 6.7 %. For three years of research, the maximum seed yield was observed in Otrada 2.60 t/ha, slightly lower in Nata 2.50 t/ha and Ros 2.40 t/ha, which was obtained by seed treatment with the bacterial preparation Rizoaktiv. Key words: common beans, variety, vegetation periods, Ryzoaktyv, grain yield.

Purpose. To identify the limiting and contributing factors for the maximum realization of the genetic potential of the fodder beans productivity. Methods. Monitoring, system analysis, test sheaf method, plot collection method, variance, correlation and regression methods. Results. It is noted that the moisture supply of the growing season of fodder beans significantly influenced the features of formation of generative organs and their abortion, which was subsequently reflected in the level of their grain yield. Even in years with sufficient moisture supply (2002, 2008), the level of flower abortion was 69.1 and 74.6%, the resulting beans – 13.8 and 24.9%, while in severely dry 2015 this indicator increased: flowers – up to 84.6%, beans – up to almost 50%. The distribution of precipitation during the growing season also significantly influenced the level of abortion of fruit elements in fodder beans. The maximum level of grain yield of fodder beans (4.88 t/ha) was noted in 2002, which accounted for 81% of the realization of the genetic potential. It should be noted that obtaining a grain yield of fodder beans of more than 4.0 t/ha makes it possible to realize their genetic potential by 73-81%. The realization of the genetic potential of the grain yield level of less than 3.0 t/ha ranged from 19 to 47%. With the level of grain yield of fodder beans more than 3.0 t/ha, but less than 4.0 t/ha, the implementation was 54-65%. Conclusions. It is proved that the limiting factor in formation of a high level of fodder beans grain yield in conditions of the right-bank Forest-Steppe is moisture, which leads to its significant fluctuations from 4.88 to 1.12 t/ha. For 19 years of growing fodder beans in 6 years the grain yield was more than 4.0 t/ha, in 8 years – less than 3.0 t/ha, in 5 – more than 3.0 t/ha, but less than 4.0 t/ha. A strong positive relationship was also noted between the amount of precipitation and the level of grain yield of fodder beans (r = 0.835). However, the moisture supply of the region makes it possible to obtain the yield of fodder beans at the level of 5.00 t/ha and realize their genetic potential by 80%.

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 %.

The article presents the results of research on the formation of corn yield for grain depending on the elements of cultivation technology in the Forest-Steppe of Ukraine. The goal of the research was to identify the influence of plant density and fertilizer system on the yield of corn hybrids for grain. The research was conducted during 2017-2019 in the research field of Bila Tserkva National Agrarian University (Bila Tserkva NAU). Research methods: field, calculation and statistical. Results. Regularities of growth, development and formation of yield by plants are revealed, both in concrete conditions of years of researches, and taking into account average long-term values taking into account features of hybrid-oriented technology. According to the results of the experiment it was recorded that the maximum yields for growing early-maturing maize hybrid DN PIVYHA with FAO 180 in general were obtained at a pre-harvest density of 75 thousand units/ha and the use of combined organo-mineral fertilizer system - 11.09 t/ha; medium-early maize hybrid DN ORLYK, FAO 280 in general in the experiment provided a grain yield of 9.60 t/ha, and in terms of 2017 - 7.86 t/ha, in 2018 - 11.22 t/ha and in 2019 - 9, 72 t/ha, but the medium-ripe hybrid of corn DN SARMAT, FAO 380 provided a grain yield of 10.81 t/ha, and in the context of 2017 - 9.31 t/ha, in 2018 - 11.68 t/ha and in 2019 - 11.44 t/ha. Significant influence on the formation of the yield of corn has a hybrid factor (27 %), fertilizer system determines the level of productivity by 21 % and interacts closely with the conditions of the growing season (factor BV 9 %), growing season conditions also determine the level of productivity of corn plants (19 %), and the pre-harvest density determines this feature by 18 %. Conclusions: In the conditions of the Right Bank part of the Forest-Steppe of Ukraine there is an increase in the level of productivity of maize hybrids from early to medium-ripe hybrids, regardless of the influence of other experimental factors.

Aims: This study aimed to evaluate the influence of nitrogen fertilization and inoculation of seeds with Rhizobium tropici on the agronomic performance of common bean (Phaseolus vulgaris L.). Study Design: The experimental design consisted of a randomized block in a 4x2 factorial layout, with 4 replicates, the first factor referring to inoculant doses (0, 50, 100 and 200 mL for each 25 kg of seed), while the second refers to nitrogen fertilization (0 and 40 kg ha of N). Place and Duration of Study: The study was conducted to the field in a no-till system area, in the southwestern region of Paraná, Brazil. The soil is classified as a Purple Latosol, with a clayey texture. Methodology: The adopted spacing was 0.45 m between rows, and the seeding density used was 12 seeds per furrow meter. The inoculants NITRO 1000 Rhizobium tropici SEMIA 4077 and SEMIA 4088 were applied, varied according to the treatments. The cultivar used was IPR – Tangará. Results: As for grain yield, it was observed that nitrogen fertilization did not contribute to the increase in grain yield, and higher productivity was obtained in the absence of N. This was probably due to the high content of organic matter present in the soil. Conclusion: Nitrogen fertilization at sowing and seed inoculation with Rhizobium tropici did not influence the plant population and the 1000-grain mass. In the absence of nitrogen fertilization at sowing, pods with a longer length and higher grain yield were obtained. Inoculation of the seeds with Rhizobium tropici exerts a positive influence on plant height, number of nodes of the main stem, number of pods per plant, and number of beans per pod, the dose recommended by the manufacturer (100 mL) being efficient, with the possibility of applying a dose of 50 mL, to satisfactory results.

Aim. To study the selection value of new spring triticale varieties according to the main economic and valuable properties (duration of the growing season, plant height, lodging resistance, resistance to diseases, tillering coefficient, grain weight from one ear, grain yield). Methods. Laboratory, mathematical and statistical, physical. Results. The duration of the growing season of spring triticale was longer compared to wheat. Thus, it was the longest in 2015–122 days, in 2014–112, and in 2013–102 days or 3–9 days more compared to wheat, except for 2014 in which the duration of the growing season of spring wheat was 117 days. This figure did not change depending on the variety of spring triticale over the years of research. The shorter growing season of spring triticale in 2013 was apparently due to the later sowing period. On average, over three years of research, the height of spring triticale plants varied from 99 to 105 cm depending on the variety. Triticale spring exceeded soft spring wheat by 2–8 %. However, Heritage durum wheat plants were the highest. This figure has changed significantly over the years of research. Thus, the highest plants were in the favourable 2014 – 108–129 cm, the shortest in the less favourable 2013 – 85–92 cm, and in 2015 – 100–106 cm. Spring triticale plants had the highest resistance to pathogens of leaf spot in 2015. In 2014, the intensity of their defeat was at the level of 4.0–4.5% with the resistance of 9 points. Triticale spring significantly exceeded the plants of both types of wheat in this respect. On the average for three years of researches, the coefficient of general spring triticale tillering made 1.56–1.65 depending on the variety. This indicator was at the level of durum wheat and 9–14 % lower than that of soft wheat. The productive tillering coefficient was 10–15 % lower than that of soft wheat. Of the five varieties of spring triticale, the highest grain yield was obtained for the cultivation of Kharkiv Oberih variety – 6.12 t/ha. Yields of Kharkiv Lebid, Kharkiv Sontsedar and Kharkiv Korovai varieties were 18–22 % higher compared to soft wheat and 7–11 % higher than durum wheat. Conclusions. Indicators of growth and development of spring triticale plants and grain yield change significantly depending on the variety and weather conditions of the growing season. The duration of the growing seasom of spring triticale is 102–122 days. Plants can be medium and very tall, lodging resistance varies from 5 to 9 points. Triticale spring has a very high resistance to main fungal diseases. Grain yield is 4.93–6.12 t/ha depending on the genotype. To obtain a high and stable grain yield, it is necessary to grow Kharkiv Korovai and Kharkiv Oberih spring triticale varieties.

The aim of the study is to isolate from collection samples of winter triticale the sources of short-stemming and high grain yield for their further involvement in the selection process in the forest-steppe conditions of middle Volga region. The studies were carried out in 2013–2017 on typical gray forest soils. 93 samples of winter triticale of Russian selection, obtained from the collection of All-Russian Institute of Plant Genetic Resources named after N.I. Vavilov. Standard is Bashkir short-stemmed. Weather conditions during the years of study varied significantly. The studied gene pool has a wide genetic diversity in plant height (65 ... 136 cm) and yield (277 ... 579 g/m2). According to the results of analysis of variance, a significant influence of the genotype and year conditions on the manifestation of these characters was established. Plant height and yield depended on both factors and their interaction, but the first trait is determined mainly by the heredity of the varieties (46.1%), and the second - by the growing conditions (61.8%). There was a significant variation in the values of the studied indicators, both by genotypes and by years: the coefficient of intervarietal variation in the average values of the traits of grain yield and plant height for 2013–2017 amounted to 15.0 and 17.2%, respectively, with variation by years 15 , 4 ... 30.7% and 15.1 ... 20.1%, respectively. According to the results of regression analysis, it was found that within the studied gene pool the highest grain yield was formed by samples with a plant height of 86 ... 105 cm. 13 sources of short-stemming with a plant height below 80 cm and 17 high-yielding samples with a yield of 515 ... 579 g/m2 were identified. In these genotypes, the yield excess over Bashkirskaya short-stemmed standard was significant and amounted to 33 ... 97 g/ m2, or 6.8 ... 20.1%. The varieties Tribun, Skif, Kentavr, Sotnik are characterized by the highest breeding value

Акцентовано увагу на необхідності дослідження особливостей формування урожайності насіння проса прутоподібного (світчграсу) для забезпечення виробничих площ достатньою кількістю насіннєвого матеріалу. Здійснено спроуа визначення залежності урожаю насіння від елементів технології вирощування у зв’язку з погодними умовами веґетаційного періоду. Експеримент із вивчення насіннєвої продуктивності світчграсу проведено в умовах Лісостепу з використанням методичних рекомендацій вітчизняних та зарубіжних авторів. За результати дослідження визначено комплексний вплив елементів технології вирощування на фоні контрастних умов веґетації культури на урожайність насіння світчграсу. Встановлено, що на урожайність насіння світчграсу мають вплив погодні умови вирощування (середньодобова температура повітря та кількість опадів) протягом веґетаційного періоду. Найбільша урожайність насіння формується за вирощуванні рослин за ширини міжряддя 60 см, Як ширші, так і вужчі міжряддя зменшують даний показник. Визначено рівнозначний вплив біометричних показників рослин (висоти та кількості стебел) на урожайність насіння світчграсу. При цьому застосування весняного підживлення посівів певною мірою нівелює негативний вплив погодних умов. The article focuses attention on the necessity of studying the peculiarities of the formation of switchgrass yield for providing productive areas with sufficient amount of seed material. An attempt to determine the dependence of yield on the elements of cultivation technology in connection with the weather conditions of the growing season has been made. The experiment on studying seed efficiency of switchgrass was carried out under the conditions of the Forest-Steppe using methodolo-gical recommendations of domestic and foreign authors. The yield of seed was determined by weighing method by weighing the seed material from each variant of the field experiment. In our study we used both general scientific methods (dialectics, experiment, analysis and synthesis) and special ones, among them: laboratory – the determination of quantitative indices of plants (height and density of stems); field – determination of the interaction of the subject with the object of research; calculation-weight – establishment of seed productivity and yield of seeds; mathematical analysis of interconnections and graphical representation of data in the experiment.  Complex influence of the cultivation technology elements during the contrast conditions of crop vegetation upon the switchgrass yield has been established. It has been determined that the weather conditions (average daily air temperature and rainfall) during the growing season influenced on switchgrass yield. The highest seed yield is formed by growing plants at a width of rotation of 60 cm, both wider and narrowed row spacings reduce this figure. The equivalent effect of biometric indices of plants (height and number of stems) on the yield of the seed of the switchgrass is determined. At the same time the application of spring crop yields to some extent offsets the negative effects of weather conditions.  Application of fertilizers in plant cultivation with row spacing of 60 cm – from 0.57 t/ha to 0.72 t/ha has the greatest influence on swithgrass yield. Both increase and decrease of the width of row spacing leads to decrease of  crop yield. Swithgrass yield depends on the height of the plants by 25% under the coefficient of correlation r = 0.51 and by 23% – on the number of stems according to the correlation coefficient r = 0.48.

The results of a field experiment to study the effect of seed treatment with the biological product Rhizoactive (сompany BioNorma, Ukraine) on the formation and functioning of the symbiotic apparatus of common bean (grain) plants are presented. The experiment examined six varieties of common beans (grain), included in the State Register of plant varieties suitable for distribution in Ukraine: Bukovynka, Halaktyka, Slaviia, Ros, Otrada, Nata. The influence of bacterial fertilizer based on nodule bacteria " Rhizoactive " on the indicators of symbiotic and grain productivity of these varieties of common beans was studied. It was found, that the maximum number and raw weight of active nodules in the studied varieties of common beans were formed in the flowering phase. A larger number of nodules, compared to the variety Bukovynka (control), was formed on the root system of bean varieties Ros, Otrada and Nata. The maximum raw weight of rhizobia in the plots without the use of Rhizoactive was formed by the common bean variety Otrada – 0.297 g/plant of active nodules. Inoculation of the seeds of the studied common bean varieties with Rhizoactive increased the raw weight of active nodules in the flowering phase by 0.016–0.042 g/plant. A larger mass of nodules, compared to the Bukovynka variety, was formed on the root system of Ros, Otrada and Nata beans. The maximum raw weight of rhizobia in areas without the use of Rhizoactive was formed by the variety of beans Otrada – 0.297 g/plant of active nodules. Inoculation of seeds of the studied varieties of beans with Rhizoactive increased the raw weight of active nodules in the flowering phase by 0.016–0.042 g/plant. The highest increase in grain yield from seed inoculation was obtained in 2018, which was more favorable in terms of moisture. Thus, the largest increase in grain yield from the use of Rhizoactive was provided by the varieties Halaktyka (0.14 t/ha or 5.7 %), Ros (0.15 t/ha or 5.5 %) and Otrada (0.22 t/ha or 7.7 %). On average, in 2018–2020, inoculation of bean seeds with Rhizoactive, depending on the variety, provided an increase in grain yield from 2.4 to 6.7 %. And the highest level of bean grain yield on average in 2018–2020 was provided by the varieties Otrada (2.60 t/ha), Nata (2.50 t/ha) and Ros (2.40 t/ha) for inoculation of seeds with Rhizoactive

Исследования проводились в лесостепи Восточной Сибири в 2018–2019 годах. Для создания сортов гороха (Pisum sativum L.) с высокой кормовой продуктивностью необходимо включать в селекционный процесс листочковые формы вместо более технологичных усатых сортов. Цель исследования — анализ коллекции гороха листочкового морфотипа для селекции на кормовые цели. Материалом для исследования послужили 20 образцов гороха листочкового морфотипа. Образцы оценивали по укосной и зерновой продуктивности. Погодные условия в годы проведения исследований отличались от среднемноголетних значений: 2018 год был очень засушливым (ГТК — 0,60), 2019 год — засушливым (ГТК — 0,89). Урожайность зависела от биологических особенностей сорта и погодных условий годов исследований. Следует отметить высокую продуктивность сорта гороха полевого Интенсивный 92: в оба года он попал в верхнюю часть ранжированного списка, превысив стандарт. В среднем по урожайности зелёной массы сорт Интенсивный 92 превосходил стандарт Радомир на 3,40 т/га, по урожайности семян — сорт Орпела на 0,10 т/га. Рентабельность производства зелёной массы сорта Интенсивный 92 оказалась на 53,7% выше стандарта. По рентабельности производства зерна сорт Орпела превысил стандарт на 8,8%. Выделены источники важных хозяйственных признаков: для селекции на увеличение урожайности семян — горох полевой Орпела; урожайности зелёной массы — сорта Апостол и Интенсивный 92; в качестве источника семенной продуктивности растений — сорта Тюменский кормовой, Шал, Орпела; устойчивости к полеганию — Альбенс и Орпела; устойчивости к аскохитозу и тле — Clause и Id 29200910. The investigation took place in the forest-steppe of the Eastern Siberia in 2018–2019. To create pea (Pisum sativum L.) varieties with high feed productivity, it is necessary to include leafy forms in a breeding process instead of leafless varieties suitable for machine harvesting. The research aimed at screening a collection of leafy peas for breeding feed varieties. 20 leafy varieties were analyzed according to their green mass and grain productivity. Weather conditions differed from the long-term average values: 2018 was very dry (hydrothermal index = 0.60), 2019 — dry (hydrothermal index = 0.89). Productivity depended on plant biology and meteorological conditions. Pea variety “Intensivny 92” showed high productivity ; it hit the top of the ranked list, exceeding the standard in both years. “Intensivny 92” exceeded the standard “Radomir” in green mass yield by 3.40 t ha-1 and“Orpela” — in grain productivity by 0.10 t ha-1. The profitability of green mass production of “Intensivny 92” was 53.7% higher than the standard. The profitability of “Orpela” grain production exceeded the standard by 8.8%. The sources of economically important traits were found: field pea “Orpela” — to increase grain yield; “Apostol” and “Intensivny 92” — for high green mass yield; “Tyumenskiy kormovoy”, “Shal”, “Orpela” — high seed productivity; “Albens” and “Orpela” — lodging resistance; Clause and Id 29200910 — resistance to Ascochyta leaf spot and aphids.
