В России постоянно растет спрос на свежие плоды перца и продукты переработки этой культуры. В товарном производстве все шире используют гибриды перца. Возделывание гибридов должно учитывать их биологические особенности и способствовать реализации их продуктивного потенциала. Цель исследования: совершенствование отдельных элементов технологии возделывания новых отечественных гибридов перца сладкого для обеспечения получения высоких урожаев экологически безопасной продукции. Исследования проводили в 2016–2019 годах в Селекционно-семеноводческом центре «Ростовский» Агрохолдинга «Поиск» в Ростовской области. Сумма осадков за период с марта по октябрь составляла 268 мм. Сумма активных температур свыше 10 °С превышала 3200 °С. Почвы в опытах – чернозем обыкновенный. Содержание гумуса в пахотном слое – 4,2%. Реакция почвенной среды – щелочная, рНKCl - 7,8. Перец выращивали рассадным методом. Высадка рассады в открытый грунт – в первой декаде мая. Предшественник – огурец. Орошение капельное с системой фертигации. Схема опытов включала три варианта: контроль (традиционная технология с применением комплексных балластных удобрений и химических препаратов для защиты растений); комбинированная технология с применением комплексных балластных удобрений в основное внесение, комплексных безбалластных водорастворимых удобрений в подкормки с сочетанием биологических и химических средств защиты растений; биологизированная технология с применением органических удобрений в основное внесение, посевом на сидераты промежуточных злаковых культур, применением комплексных безбалластных водорастворимых удобрений в подкормки и биологических средств защиты растений. Материалом для исследований служили гибриды перца F1Илона и F1 Байкал. В результате исследований установлено, что по комплексу показателей преимущество перед другими имела комбинированная технология производства. Возделывание новых отечественных гибридов перца сладкого F1 Илона и F1 Байкал по комбинированной технологии экономически выгодно. Урожайность гибридов превышала 70 т/га, при себестоимости менее 6 р/кг и уровне рентабельности более 110%. The demand for fresh pepper fruits and processed products is constantly expansion in Russia. In commodity production, pepper hybrids are increasingly being used. The cultivation of hybrids should take into account their biological characteristics and contribute to the realization of their productive potential. The aim of the study is to improve individual elements of the technology of cultivating new domestic hybrids of sweet peppers to ensure high yields of environmentally friendly products. The research was carried out in 2016–2019 at the Breeding and seed production centre Rostovsky of Poisk Agro Holding In the Rostov region. The amount of precipitation for the period from March to October is 268 mm. The amount of active temperatures in excess of 10 °C exceeds 3200 °C. Soils in experiments – ordinary chernozem. The humus content in the arable layer is 4.2%, pHKCl-7.8. Pepper was grown by seedling method. Planting in the first decade of may. The predecessor is a cucumber. Drip irrigation with fertigation system. The scheme of experiments included 3 variants: standard (traditional technology using complex ballast fertilizers and chemicals to protect plants products); combined technology with the use of complex ballast fertilizers in the main application, feeding complex ballast-free water-soluble fertilizers, a combination of biological and chemical plant protection products; biological technology using organic fertilizers in the main application, sowing on the siderats of intermediate cereal crops, the use of complex ballast-free water-soluble fertilizers in fertilization and biological plant protection products. The material for the research was the hybrids of pepper F1 Ilona and F1Baikal. As a result of the research, it was found that the combined production technology had an advantage over others. The cultivation of new domestic hybrids of sweet peppers F1 Ilona and F1 Baikal on combined technology is economically profitable. The yield of hybrids exceeded 70 tons per hectare, at a cost of less than 6 rubles/kg and the level of profitability of more than 110%.

<p>The influence of long-term use of mineral and organic fertilizers, crop rotations, plant residues, soil treatment systems on humus content of common chernozems and stabilization of productivity of field crops in the arid conditions of the Middle Volga region is considered on the example of researches in the Samara area. The zone climate of field experiments is characterized as extremely continental. The sum of the active temperatures (above 10°C) is 2,800-3,000°C. The average annual rainfall is 454.1 mm with fluctuations over the years from 187.5 mm to 704.6 mm. At some years, precipitation does not happen within a month or more. Hydrothermal index in May-August is 0,7, the duration of the frost-free period is 149 days. If the humus content in the region is 4.35-4.52%, then, it is necessary to introduce 6.7-8.0 t/ha of manure per year to maintain the balance of the deficit. The introduction of biological methods for the conservation and reproduction of soil fertility (green fertilizers, perennial grasses, straw as fertilizer) reduces the loss of humus by 0.15-0.24 t/ha. This makes it possible to increase the payback of mineral fertilizers, which must be taken into account when developing fertility reproduction systems for soils. In the variants with minimal and differentiated cultivation of the soil during crop rotation in 30 years of the study, the loss of humus in the 0-30 cm layer decreased by 0.04 - 0.73% (43-789 kg per year with maximum values in the combination of direct seeding of spring crops with deep loosening for a number of crop rotations is 4.14%, significantly exceeding the control (by 0.54%). The decrease in soil fertility in the variants with constant plowing and minimal tillage contributed to an increase in the conjugation of productivity of crops with humus. Based on the research, in order to preserve the fertility of the soil of ordinary chernozem, it is necessary to use green fertilizer, leguminous perennial grasses. In the regional rotations of crop production, new generation technologies are recommended, the basis of which is differentiated tillage with the use of crushed straw as fertilizer.</p>

У статті викладені результати досліджень щодо ефективності вирощування конопель в умовах класичної технології та органічного землеробства. Визначено, як технологія вирощування конопель впливає на зміну біологічного стану ґрунту, урожайність насіння та стебел, а також започатковано вивчення шляхів забезпечення культури конопель елементами живлення. Дослідженнями встановлено, що вирощування конопель сорту Гляна в умовах органічного виробництва не сприяє підвищенню урожайності насіння, порівняно із перехідною від класичної до біологічної технології (інтенсивною). Накопичення і трансформація свіжої органічної речовини рослинних решток конопель залежить від складових технології органічного землеробства, які дають змогу мікрофлорі ґрунту не переносити стресових навантажень від впливу міндобрив і засобів захисту рослин. The article presents the results of research on the effectiveness of hemp cultivation in the conditions of classical technology and organic farming. It has been determined how the technology of hemp cultivation influences the change of the biological state of the soil, the yield of seeds and stems, as well as the study of ways to ensure the culture of hemp with nutritional elements. The research has established that the cultivation of hemp straw in the conditions of organic production does not contribute to increasing the yield of seeds, compared with the transition from classical to biological technology (intensive). The accumulation and transformation of fresh organic matter of the hemp plant residues depends on the components of the organic farming technology, which enable the microflora of the soil to not tolerate stress from the effects of fertilizer and plant protection products.

Purpose: to identify factors enhancing the negative impact of long-term irrigation on soil fertility. Materials and methods. The influence of mineralization and quality of irrigation water on ordinary chernozems (Neklinovsky district), the level of groundwater table on the reclamation state and soil fertility of ordinary chernozems (Bagaevsky district of Rostov region), the structure of crop rotations was studied, and optimal moisture levels for different irrigation modes were established. Results. Long-term use of sulphate-sodium low-mineralized water led to the degradation of ordinary chernozems. They acquired the properties of medium alkaline and medium solonized soils: alkalinity – 1.29 mmol(eq)/100 g, solonetzicity – 7 % of exchangeable sodium from the total soil absorbing complex (SAC), soil bulk density – 1.34 t/m³, humus content decreased by 23 % during its transformation from fulvate-humate to humate-fulvate. The close ground waters table and their mineralization of 5 g/dm³ contributed to secondary salinization. Fertility reproduction is observed only with the introduction of organic fertilizers. The increase in humus content in the alfalfa-corn crop rotation was 0.68 % with the introduction of 60 t/ha of manure after 4 years of corn cultivation in comparison with the humus content after 3 years of alfalfa cultivation, and in the grain feed – 0.55 %. It was found that with an increase of irrigation rate up to 30 %, leaching of exchangeable calcium is observed with a simultaneous increase in the content of exchangeable sodium up to 4 % of the total SAC, which contributes to an increase in bulk density of ordinary chernozem to 1.38 t/m³. In the variant with over-irrigation, the humus content decreased by 0.22 % over 4 years of regular irrigation, and in the variant with the optimal and reduced by 40 and 60 % rates, its amount decreased from 0.04 to 0.07 %, as in dry land. Conclusions. The investigated factors enhance under certain conditions the negative impact of long-term irrigation on the properties of ordinary chernozem.

The paper contains the research results on the evolution of humus content in the arable soils of the Republic of Moldova during 1961–2010. The current humus state of arable soils caused of the agricultural long period of utilization. Studies carried out in Moldova, more than 140 years ago, found that chernozem contained about 5–6 % of humus. In subsequent years, the natural fertility of the soil of Moldova has been declining. In the present the humus content reached the level of 3.1 % on average for the whole agricultural area. As a result of over 140 years from the original natural soil fertility remains 50–60 %. In the recent years the average doses of applied fertilizers on the Moldovan soils were 25 kg/ha. During the last years, the state programs for remediation of humus content, the chemical, physical and biological soil properties, concerning the soil and water protection by the nutrient pollution and substances of plant protection products have been developed. Key words: humus loss, soil degradation, chernozem, fertilizer, measures.

The objective of this study was to assess the potential of implementing GLOBAL. G.A.P. in bean-producing farms in the region of Talas in northern Kyrgyzstan. The assessment concerned the analysis of non-conformities with the GLOBAL G.A.P. standard in farms that had implemented the standard but had not been certified. The detailed objective was to identify critical areas in implementing said standard. To achieve the objective established, research was conducted in 2018. The research covered 112 farms that produce beans (local variety called ‘Łopatka’). Internal audits were carried out in the examined farms, in accordance with the checklist of the GLOBAL G.A.P. standard version 5.1. The results of the conducted research indicate that at the current level of agricultural development and awareness of farmers from Kyrgyzstan, implementation of the GLOBAL G.A.P. standard is going to be very difficult. Problems apply both to infrastructure and to producers’ mentality. Problems with infrastructure concern primarily the places to store plant protection products as well as mineral and organic fertilizers. Moreover, the identified non-conformities concerned adequate infrastructure serving for segregation and management of waste (both production waste and municipal waste). With respect to hygiene, problems concern both lack of sanitary infrastructure, as well as producers’ mentality associated with the need for maintaining hygiene. In most cases, the issue of the possibility of improving the condition of the environment within the farm’s premises is omitted. With respect to production technology, using organic and mineral fertilizers is problematic. In no case was water, soil or products analyzed, which is obligatory in the standard being discussed. A considerable problem in the area of the study is lack of support from government entities or companies dealing with efficient implementation of the standard. Effective development of the standard also depends on educating at the level of producers, inspectorate bodies, as well as on introducing quality management courses at individual education levels to the curriculum.

В России интенсивно развивается овощеводство защищенного грунта. Наблюдается рост площадей зимних и весенних теплиц. Площадь весенних теплиц достигла 20 тыс. га. Весенние теплицы стали основным типом культивационных сооружений при производстве ранних томатов. Весенние теплицы чаще используются в мелких хозяйствах. Конструкции теплиц и применяемые технологии сильно различаются и не позволяют использовать промышленные технологии производства томата. В мелких тепличных хозяйствах сложно получать экологически безопасную продукцию. Цель исследований разработка приемов возделывания новых гибридов томата в весенних теплицах и совершенствование конструкций теплиц для получения экологически безопасной продукции. Исследования проведены в 2016-2019 годах в селекционно-семеноводческом центре Ростовский Агрохолдинга Поиск , расположенном в Октябрьском районе Ростовской области. Климат зоны жаркий, засушливый, с продолжительным безморозным периодом. Погодные условия в годы проведения исследований отличались резкими перепадами температуры в весенний период, высокими температурами при острой нехватке осадков и низкой влажностью воздуха в летний период. Почвы в опытах чернозем обыкновенный с добавлением рыхлящих материалов. Содержание доступных элементов питания высокое. Опыты закладывали в весенних теплицах ангарного типа с поликарбонатным светопрозрачным покрытием без обогрева. Теплицы оснащены системами капельного орошения с фертигацией. Объектом исследований служили конструкции теплиц, отдельные элементы технологии возделывания и гибриды томата. В результате исследований установлено, что для получения экологически безопасной продукции томата в весенних теплицах необходима их модернизация с увеличением внутреннего объема за счет увеличения высоты по коньку до 4,5 м. Теплицы должны быть оснащены вытяжной вентиляцией, противомоскитными сетками на вентиляции, тамбуром с дезинфекционным барьером на входе. В технологии выращивания томата необходимо включить использование промежуточных злаковых культур с заделкой на сидераты и комплексных безбалластных водорастворимых удобрений в корневых и листовых подкормках. Подвязка и формировка растений томата должна учитывать сортовые особенности. Для защиты от вредных организмов необходимо использовать сочетание комплексной устойчивости новых гибридов томата с применением биопрепаратов, карантинных, профилактических и агротехнических мероприятий. Модернизация весенних теплиц и внедрение предложенных элементов технологии выращивания томата позволяют обеспечить гарантированное получение экологически безопасной продукции.In Russia the vegetable production of protected soil is developing intensively. There is an increase in the area of winter and spring greenhouses. The area of spring greenhouses has reached 20 thousand ha. Spring greenhouses have become the main type of cultivation structures in the production of early tomatoes. Spring greenhouses are more often used in small farms. The constructions of greenhouses and the technologies used vary greatly and do not allow the use of industrial technologies for the production of tomatoes. In small greenhouse farms it is difficult to obtain environmentally safe products. The main purpose of the research is to develop technology for cultivating new tomato hybrids in spring greenhouses and to improve greenhouse constructions to produce ecological safely products. The research was carried out in 2016-2019. at the Rostovsky breeding centre of Poisk Agro holding, located in the October district of Rostov region. The climate of the zone is hot, arid, with a long frost-free period. Weather conditions during the study years were characterized by sharp temperature changes in the spring, high temperatures with severe lack of precipitation and low humidity in the summer. Soils in experiments ordinary chernozem with the addition of loose materials. The content of available batteries is high. Experiments were laid in spring greenhouses hangar type with polycarbonate translucent coating without heating. The greenhouses are equipped with drip irrigation systems with fertigation. The object of research was the construction of greenhouses, individual elements of the technology of cultivation and hybrids of tomato. As a result of research, it has been established that in order to obtain environmentally safe products of tomatoes in spring greenhouses, they need to be modernized with an increase in internal volume by increasing the height of the skate to 4.5 m. Greenhouses should be equipped with exhaust ventilation, mosquito nets on ventilation, a tambour with a disinfectant barrier at the entrance. In tomato growing technology it is necessary to include the use of intermediate cereal crops with rooting on siderates and complex ballast-free water-soluble fertilizers in root and leaf fertilization. The garter and formation of tomato plants should take into account varietal features. To protect against harmful organisms, it is necessary to use a combination of complex stability of new hybrids of tomato with the use of biologics, quarantine, preventive and agrotechnical measures. Modernization of spring greenhouses and the introduction of the proposed elements of tomato growing technology make it possible to ensure the guaranteed receipt of ecological safely products
