В условиях нестабильной геополитической ситуации в мире, в нашей стране остается открытым вопрос обеспеченности семенами отечественной селекции, доля которых должна быть не менее 75% от общего объема. Препятствиями в этом отношении являются проводимая за последнее время агрессивная политика...

Представлены результаты полевых опытов по изучению эффективности гербицидов на капусте белокочанной в закрытом акционерном обществе «Агрофирма «Победа» Псковского района Псковской области. Изучена возможность снижения численности и массы сорного компонента агроценоза за счет использования на...

Картофель является одной из важных продовольственных культур нашей страны. В его клубнях содержатся все необходимые для организма макро- и микроэлементы, витамины. Он служит сырьём для многих отраслей промышленности, хорошим предшественником для других культур. Учитывая высокую засорённость полей,...

Большинство полей южной части Псковской области засорены в средней или сильной степени. При этом видовой состав сорного компонента - сложный, представленный корневищно-малолетним или корнеотпрысково-корневищно-малолетним типами. Одним из опасных и трудноискоренимых сорняков такого компонента на...

Potatoes are crops that require both soil moisture and humidity. If there is a lack or excess moisture level in the growing process, it is practically impossible to achieve a total yield of high-quality potatoes. The traditional method of water supply to potato planted plots is practiced primarily...

We studied the changes in morphophysiological (gonadosomatic index, hepatosomatic index, spleen index) and biochemical (protein, glycogen, lipids, malonic dialdehyde, thyroxine, triiodothyronine, and cortisol) parameters in redfish under the action of toxic loading. Two lakes were chosen as model...

Sea buckthorn (Hippophae rhamnoides L.) is a unique and valuable crop. Its raw materials (fruits, leaves, seeds) due to therapeutic and consumer characteristics are demanding globally. In Ukraine, the H. rhamnoides industry has yet to be developed. However, with recent emerging interest and...

Aim. To establish the spatial and temporal variability in yield of corn for grain in the Volyn region in 1965-2017. Methods. Agricultural research, multivariate statistics, cluster analysis, geographic information technology. Results. From 1965 to 2015, the highest yield of corn for grain in the...

The purpose of the research is to study the effect of feeding an active coal feed supplement (ACFS) on biological fish-breeding indicators of young fish grown in closed water supply plants. The experiment was conducted in the conditions of a sturgeon farm in the Krasnodar territory. The object of...

The article highlights the results of studying the influence of agrometeorological conditions on the growth and development of spring wheat, the variability of morphological markers of the studied samples. The regularities of the influence of hydrothermal factors of growing conditions on the...

The course of the research has been specified the regional list of Gherkin hybrid cucumber diseases. It is established that the dominant position in the pathogenic community of this vegeTable crop when growing under open ground conditions is occupied by the population of oomycetes representative...

Many recent studies have shown that bees and bee products can selectively accumulate heavy metals, radioactive substances, pesticides, and other contaminants. The work aimed to assess the ecological quality of beekeeping products and adult bees for the content of some inorganic elements. The amount ...

New agricultural operations using intensive technologies more and more intensify processes of soil cover degradation, which are substantially accelerated due to climate changes. Climate is the primary factor that determines agricultural productivity. Due to the significant increase of air...

Aim: To establish the influence of a complex of factors on productivity of short crop rotations with the cultivation of commercially attractive crops, the reproduction of soil fertility is based on optimized agrochemical supply by replacing litter manure with by-products in the conditions of low...

We were studied the influence of 2-chloroethylphosphonic acid (2-CEPA) on the rate of fruit ripening of tomatoes Solerosso hybrid under production conditions. The treatment of 0.3% 2-chloroethylphosphonic acid at the stage of 25% fruit ripeness is highly effective method to accelerate the ripening...

Cotton is one of the most important cash crops in the world. Cotton plants cultivated in more than 80 countries around the world within 30 million hectares of land. In recent years, global climate change, shrinking water resources, deteriorating reclamation of arable land, and growing demand for...

Purpose. The purpose of the research was to establish the possibility of expanding beardbeardless tillage in the cultivation of beets by combining them with soil herbicides in the Western Forest-Steppe of Ukraine. Methods. Field, analytical and statistical. Results. We found that the use of...

The study evaluates the effect of water stress on the microorganisms biomass of the rhizosphere associated with cereal cultivation. The latter selects the most resistant germs to introduce them into the improvement of the system: soil-plant under water stress condition. The study of the effect of...

The complex of cruciferous bugs includes such species as painted or harlequin (cabbage) bug (Eurydema ventralis Kol), pentatomid rape bug (E. oleraracea L.), and mustard bug (E. ornata L.).
