Abstract This research explores the compactness of apple varieties and forms with different types of crown. Orchards on semi-vigorous rootstocks with density and high density planting systems are cost-effective in modern horticulture. For making such gardens, it is necessary to have trees with special compact crown shape. They ensure the high-quality fruits production, meeting the requirements of world standards. To date the most perspective apple varieties and forms for domestic intensive gardening from the rich gene pool of the Selection and Genetic Center of Federal State Scientific Institution «I. V. Michurin Federal Scientific Center» are identified. Varieties of folk domestic and foreign breeding took part in the creation of new genotypes. Apple varieties and promising forms (more than 160 genotypes), including from near and far abroad selection, were used as materials for crown features studying. We conducted our study by the following indicators: tree height, crown volume, “degree of compactness” and the shoot-forming ability. We found that the genotypes Sholokhovskoye, Zvezda Artemyeva, 25-7(11), 40-9(8), 36-8(21), 40-9(6), 8-7(72), 40-9(7), 36-8(17), 62-5(140) have optimal crown parameters. We recommend their use for industrial horticulture and further breeding to create restrained growth, low-volume crown, and a high degree of compactness varieties.

The article presents the results of a five-year study of the yield of the Melba apple variety on dwarf, semi-dwarf and medium-sized rootstocks selected by the North Caucasus Federal Scientific Center for Horticulture, Viticulture, and Winemaking (SKFNCSVV). The aim of the research is to study the influence of rootstocks of different growth strengths on the productivity potential of the Melba apple variety in the natural and climatic conditions of the Astrakhan region. The research revealed the influence of the rootstock genotype on the main productivity indicators: perishability, yield, frequency of fruiting, stability of productivity, marketable qualities of fruits. The early fruitfulness of the variety was most affected by the dwarf subspecies SK 3, SK 7 and semi-dwarf SK 2, on which 60–100% of the trees bloomed in the first year of growth in the garden. Among the studied combinations, the highest rates of crop growth in the Melba variety were noted on the dwarf rootstock SK 3 and semi-dwarf SK 2, in combination with which the variety was characterized by maximum values of average (19.4–16.3 t/ha) and total yield (97.2–81.6 t/ha), with the values of these indicators on the control variants 16.0–10.6 t/ha and 80.2–53.1 t/ha respectively. Low indicators of the periodicity index were noted on the dwarf rootstock SK 3 (15.6) and semi-dwarf rootstock: control M 26 (23.0), SK 2 (20.0), SK 5 (27.5), high index of productivity stability (0.75–0.86) – on rootstocks SK 3, SK 2 and SK 5. In the arid conditions of the Astrakhan region, the zoned variety Melba is recommended to be grown in an intensive garden on rootstocks SK 3 and SK 2, which ensure regular and stable yields.

Приведены экспериментальные данные оценки по хозяйственно полезным признакам одиннадцати новых партенокарпических гетерозисных гибридов огурца в условиях весенне-летнего оборота Кировской области. Проблема возделывания теплолюбивых культур в северных регионах страны формирует цели селекционных исследований. Выращивание культуры огурца в Кировской области усугубляется неблагоприятными климатическими условиями второй световой зоны (короткая продолжительность вегетационного периода, низкие положительные температуры, заморозки в третьей декаде июля и в первой декаде августа). Цель научной работы – оценка и выявление перспективных партенокарпических гетерозисных гибридов огурца для выращивания в условиях необогреваемых теплиц в весенне-летнем обороте второй световой зоны. Исследования проводили в лаборатории северного овощеводства Кировской области во Всероссийском научно – исследовательском институте овощеводства – филиале ФГБНУ «Федеральный научный центр овощеводства» в условиях поликарбонатных необогреваемых грунтовых теплиц в течение 2018-2019 годах. В результате фенологических наблюдений и оценки биометрических показателей определены раннеспелость, скороспелость и товарность испытуемых партенокарпических гетерозисных гибридов огурца селекции Агрохолдинга «Поиск» и ВНИИО – филиала ФГБНУ «Федеральный научный центр овощеводства»: F1Авоська, F1 Атос, F1 Букет для мамы, F1Малахитовая шкатулка, F1 Мультифрут, F1 Новатор, F1Пилигрим, F1 Спринтер, F1 Реванш, F1 Тонус, F1Экспресс в сравнении с районированным гибридом огурца F1 Каролина. Определено сильное негативное влияние климатических условий второй световой зоны на продолжительность периода «всходы-плодоношение», который в среднем за годы исследований в зависимости от гибрида варьировал от 47 до 55 суток. Установлено, что для получения ранней продукции огурца в условиях поликарбонатных необогреваемых грунтовых теплиц Кировской области следует выращивать гетерозисные партенокарпические гибриды огурца F1Спринтер (3,6 кг/м2), F1 Авоська (2,1 кг/м2) и F1 Атос (2,5 кг/м2). Отмечены партенокарпические гибриды огурца F1 Спринтер и F1 Атос, которые имеют наиболее высокий выход товарной продукции 95,7 и 94,0%, соответственно. Выделен самый урожайный партенокарпический гибрид огурца F1 Новатор (16,1 кг/м2). В результате исследовательской работы рекомендовано выращивать в условиях необогреваемых теплиц весенне-летнего оборота Кировской области партенокарпические гибриды огурца F1 Новатор, F1 Спринтер, F1 Атос и F1 Авоська. The article presents the experimental data on the assessment of economically useful traits of eleven new parthenocarpic heterotic cucumber hybrids under the conditions of the spring-summer turnover of the Kirov region. The problem of cultivation of thermophilic crops, which arises in the northern regions of the country, is one of the stages of breeding research. The cultivation of cucumber in the Kirov region is aggravated by unfavorable climatic conditions of the second light zone (short duration of the growing season, low positive temperatures, frosts in the third decade of July and in the first decade of August). The purpose of the scientific work is to evaluate and identify promising parthenocarpic heterotic hybrids of cucumber for growing in unheated greenhouses in the spring-summer turnover of the second light zone. The research was carried out in the laboratory of northern vegetable growing of the Kirov region at the All-Russian Research Institute of Vegetable Growing - a branch of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Centre in the conditions of polycarbonate unheated ground greenhouses during 2018-2019. As a result of phenological observations and assessment of biometric indicators, the early maturity, early maturity and marketability of the tested parthenocarpic heterotic cucumber hybrids of the selection of Agroholding Poisk and ARRIVG – a branch of the Federal Scientific Vegetable Centre were determined: F1 Avoska, F1 Atos, F1 Buket dlya mamy, F1 Multifrut, F1 Novator, F1 Piligrim, F1Sprinter, F1 Revansh, F1 Tonus, F1 Express in comparison with the zoned hybrid of cucumber F1 Carolina. A strong negative influence of climatic conditions of the second light zone on the duration of the seedling-fruiting period was determined, which on average over the years of research, depending on the hybrid, varied from 47 to 55 days. It has been established that to obtain early production of cucumber in polycarbonate unheated ground greenhouses of the Kirov region, heterotic parthenocarpic cucumber hybrids F1 Sprinter (3.6 kg/m2), F1 Avoska (2.1 kg/m2) and F1 Atos (2.5 kg/m2). Parthenocarpic cucumber hybrids F1 Sprinter and F1 Atos were noted, which have the highest yield of marketable products, 95.7 and 94.0%, respectively. The most productive parthenocarpic cucumber hybrid F1Novator (16.1 kg/m2) has been identified. As a result of the research work, it was recommended to grow parthenocarpic cucumber hybrids F1Novator, F1 Sprinter, F1 Atos and F1 Avoska under conditions of unheated greenhouses of spring-summer turnover of the Kirov region.

Agricultural advancements have significantly impacted people’s lives and their surroundings in recent years. The insufficient knowledge of the whole agricultural production system and conventional ways of irrigation have limited agricultural yields in the past. The remote sensing innovations recently implemented in agriculture have dramatically revolutionized production efficiency by offering unparalleled opportunities for convenient, versatile, and quick collection of land images to collect critical details on the crop’s conditions. These innovations have enabled automated data collection, simulation, and interpretation based on crop analytics facilitated by deep learning techniques. This paper aims to reveal the transformative patterns of old Chinese agrarian development and fruit production by focusing on the major crop production (from 1980 to 2050) taking into account various forms of data from fruit production (e.g., apples, bananas, citrus fruits, pears, and grapes). In this study, we used production data for different fruits grown in China to predict the future production of these fruits. The study employs deep neural networks to project future fruit production based on the statistics issued by China’s National Bureau of Statistics on the total fruit growth output for this period. The proposed method exhibits encouraging results with an accuracy of 95.56% calculating by accuracy formula based on fruit production variation. Authors further provide recommendations on the AGR-DL (agricultural deep learning) method being helpful for developing countries. The results suggest that the agricultural development in China is acceptable but demands more improvement and government needs to prioritize expanding the fruit production by establishing new strategies for cultivators to boost their performance.

Abstract Severe climate alterations that seriously challenge fruit production, combined with the demand for healthy, pesticide-free fruits, continuously direct rootstock/cultivar selection towards high adaptable varieties breeding. This study aimed to investigate the rootstocks’ influence on the performance of grafted ‘Summit’ cherry trees, including potentially dwarfing Prunus cerasus, Prunus fruticosa and Prunus mahaleb rootstock candidates. Anatomical properties of rootstock and scion stems were investigated to determine variation among different rootstocks and scion-rootstock combinations and to establish the link between trunk hydraulic conductivity, effective tree crown volume and yielding potential. Cross-section anatomical characteristics varied significantly both in rootstock and scion stems, indicating a clear influence of rootstock genotype on grafted sweet cherry trees. It was observed that all investigated cherry rootstock candidates belong to the low-vigorous rootstocks, based on the estimated effective crown volume of grafted trees compared to ‘Gisela 5’, with values ranging from 0.86 to 2.97 m3 in the fifth year after planting. Results showed a statistically significant positive correlation between trunk hydraulic conductivity, effective tree crown volume and yielding potential, with correlation coefficients up to 0.96. Significantly higher effective crown volume and trunk hydraulic conductance of trees grafted on P. cerasus compared to the trees on control, as well as highest yielding potential, showed better adaptation of these rootstock candidates in the trial without irrigation implemented. It was found that PC_05_04 rootstock candidate could be considered as the most appropriate choice when raising the high-density sweet cherry plantations, due to assessed parameters of vegetative and generative growth.

The annual average area sown with barley (Hordeum vulgare) in South America during 1999–2003 was 795 000 ha. In Argentina, Brazil, Chile and Uruguay, two-rowed spring cultivars are used mostly for malt production. Research has been developed in private malting companies and official institutions supported by the industry. In Argentina, tolerance to drought and heat stress during grain filling are important in drier areas. Yield and malt extract had been improved in cultivars released from 1940 to 1998. In Brazil, progress in grain yield, grain size, malting quality, early maturity, and resistance to net blotch, powdery mildew, and leaf rust has been achieved by EMBRAPA and malting companies. Higher tolerance to soil acidity and resistance to spot blotch are required. Since 1976, malting barley breeding in INIA-Chile has improved grain yield, grain size, beer production efficiency, and resistance to scald, net blotch, stripe rust, and leaf rust. Uruguay produces high quality malt exported mainly to Brazil. Malting companies have released locally bred and introduced cultivars since the early 1970’s. Initiated in 1988, INIA-Uruguay breeding program has improved yield, malting quality, and lodging and disease resistance. Fusarium head blight is a new challenge for research in Brazil and Uruguay. Information regarding malting barley production, the most important stresses in different areas of production, and breeding progress under South American conditions is provided.

SynopsisIn Scotland horticultural food crops occupy about 1·4% of the tillage land, and contribute about 4% of the total Scottish agricultural output. Climate, soil type and factors such as distance to markets and availability of labour have influenced the location of horticultural crops. This has changed with time, particularly because of the influence of the processing industry. Soft fruit production (3,630 hectares), with raspberries being the dominant crop, is concentrated in the Tayside region; more than 90% of the raspberry crop is processed by pulping (for jam, etc.), freezing or canning. Vegetable production (6,130 hectares) is somewhat more dispersed from the Border region to the Moray Firth; more than half the total area is occupied by peas for canning and freezing. Glasshouse production of tomatoes is now only 25 hectares located mainly in the Clyde Valley.The future for Scottish horticultural food production will continue to be influenced by the requirements of the processing industry, but there is also an increasing outlet for fresh fruit and vegetables in supermarkets. Expansion of the production of horticultural food crops in Scotland depends on the ability of the industry to meet market demands in terms of quality and continuity of supply. Increasing reference to the need for an improved British diet may stimulate the consumption of fruit and vegetables on the home market and there continue to be opportunities for increasing the export of processed and fresh produce. Scotland has the land resources, crop production expertise and processing and marketing facilities to respond to these opportunities.
