Spring barley is an important food, fodder and technical crop, the volume of cultivation of which is much less than the national needs for it. To date, intensive varieties of this valuable crop have been bred, which is demanding to soil fertility, which necessitates increased yields by improving the sowing quality of seeds. Modern chemical fertilizers can not provide stable plant productivity, which would ultimately increase the yield capacity of spring barley in unstable natural and climatic conditions. In addition, the use of preparations that do not threaten the environment and the quality of crops becomes relevant. One of them is bischofite, an aqueous solution of which is a natural stimulant that provides germinating power and sprouting energy of spring barley seeds. The laboratory studies on the example of three varieties of spring barley (Helios, Vakula, Parnassus) showed that soaking of the seeds in 0.1 and 1% concentration of aqueous solution of bischofite increases their germinating power and sprouting energy, which has a positive effect on the growth and development of barley, yield growth, fodder and food quality of grain. These researches allow the use of natural bischofite in agriculture in order to create the optimal conditions for growth and development of spring barley to obtain high and stable yields. Key words: bischofite, spring barley, germinating power, sprouting energy, sowing qualities.

Purpose: to analyze the experience of Russian scientists in the field of application of a differentiated approach to agricultural crops irrigation. The overview of research work of domestic scientists on the use of an irrigation system in agriculture, in which the provision of agricultural crops with water to maintain a given level of the minimum water capacity will be carried out during the most critical periods of their growth and development is presented. During irrigation, the timing, frequency, irrigation rates depend on the level of groundwater occurrence, agrochemical properties of soils, weather and climatic conditions, phases of growth and development of crops. The application of a differentiated irrigation regime to maintain a given level of pre-irrigation moisture allows increasing the productivity of agricultural crops, the quality of products obtained while reducing irrigation and watering rates, the number of waterings. Conclusions. The study of the results of research work of domestic scientists in the field of influence of irrigation and the fertilization system on the yield and quality of agricultural products allows concluding that obtaining the planned yields is possible only if irrigation regimes are observed and the level of soil fertility is maintained by applying various fertilizers. The use of a differentiated approach to irrigation while maintaining a given level of pre-irrigation soil moisture during critical periods of crop development allows reducing irrigation water consumption and optimizing irrigation rates and their quantity. The study of a differentiated irrigation regime is promising now and in the near future, taking into account the deteriorating water supply in the territory of our country, associated with a change in weather and climatic conditions.

The climate changes in Murfatlar vineyard in recent years consist inthe increase ofmonthly average temperatures, recorded in both cold and warm seasons, accompanied by an irregular distribution of rainfall during the year, which significantly influences the growth of grapevine, the quality and production of grapes.Six representative cultivars were studied, three for white wines: Chardonnay, Columna and Muscat Ottonel and three for red wines: Fetească Neagră, Mamaia and Cabernet Sauvignon. In the last two years (2019-2020) warm winters and very dry summers have led to the onset of budburst, almost simultaneously for all the studied cultivars, followed by a very weak growth and development of shoots (2020) and an acceleration development of phenophases, mainly berween veraison and ripening. Water stress during the vegetative period, a hygroscopicity below 60% between July and August and low vegetative apparatus influenced the growth ofthe berries, resulting small grapes, and a very low must yield in 2020.Concerning the quality of grape production, the studied cultivars achieved more sugar concentrations in berries up to 35.8 g/L (in 2019) and 36.0 g/L (in 2020), higher than the values obtained in normal years. In the conditions of a pronounced dry climate manifested in the two years of study, the productions were below the normal level, especialy in 2020, achieving much diminished productions for all cultivars, except the Mamaia cultivar. The Mamaia cultivar had a positive reaction, registering an increase of production, that exceeded the multiannual value by 20% in 2020 andby 10% in 2019, the concentration of sugars in the must being above the average value obtained in normal years, exceeding by 3% and 9%, respectively, the multiannual average. Statistical calculations were done using SPSS Statistics 17.0, using mainly the Duncan test for a degree of significance of 5%.

AbstractThe quality of tomato fruits is influenced by preharvest factors. Trichoderma are considered biostimulants with potential to improve growth and development in plants, as well as the quality of the fruits. The objective of this study was to evaluate the effect of foliar application of Trichoderma on the quality of tomato fruits at different cluster levels on the same plant in two commercial hybrids using three different substrates in a greenhouse. Six foliar applications of a liquid biological preparation of Trichoderma were performed at a dose of 4 mL L−1 every 15 days after transplanting. The results show that the foliar application of Trichoderma increased the ratio of soluble solids to titratable acidity of the fruits at different cluster levels, which was mainly due to the decrease in acidity rather than the increase in soluble solids. The decrease in titratable acidity is in accordance with the increase in the pH of the fruits. Trichoderma have a positive effect on titratable acidity, pH and electrical conductivity of fruits. In the Cid hybrid grown in the tezontle substrate, the application of Trichoderma increased the ratio of total soluble solids to titratable acidity. At the same time, sand increased the percentage of juice in the fruits. Foliar application of Trichoderma increases the quality of tomato fruits, and as such, should be considered as a crop management option.

ABSTRACT Nitrogen is the most important element required for plant growth and development and is the primary nutrient limiting sugarcane production. Field experiments under rainfed condition and some periods with high temperature (above 35 °C) were carried out during 2014-2015 at the municipality of Ocampo, Tamaulipas, Mexico. The objective of the study was to determine the effect of varying doses of nitrogen fertilizer on leaf photosynthesis, plant growth, total chlorophyll, and juice quality of sugarcane commercial variety Mex 79-431 in the second ratoon crop. Six nitrogen doses (0, 60, 90, 120, 150, and 180 kg N ha-1) were tested and applied as urea 60 days after harvest, at the beginning of the rainy season. The results of the experiment indicated that the application of nitrogen in ratoon crop had a positive effect on growth and development. It is important to note that further studies are required on the subject, including timing of nitrogen application, application method, soil types, other doses, and other genotypes in the region. The maximum photosynthetic rate (27.68 pmol CO2 m-2 s-1) was attained at PAR 1500 pmol m-2 s-1 with 90 kg N ha-1. The highest yield was recorded in ratoon crop with a dose of 120 kg N ha-1. At harvest, the juice quality did not show significant variations among the treatments imposed.

The search for new conditions for growing vegetables in organic crops in order to obtain safe products and in connection with changes in climatic conditions requires an immediate solution. The article considers and proves that the use of biological products affects the formation of highly productive crops and promotes the production of products with a high content of biologically active substances. Studies have shown a positive effect of biological products on the growth and development and yield of beetroot varieties Delicatessen and Red Ball. Studies have been conducted to study the technological aspects of growing vegetables, in particular with the use of biological products, taking into account the environmental impact of both growth processes and quantitative and qualitative indicators. Features of various biological products and their efficiency are analyzed. A comparative analysis of the use of biologicals, which allowed to comprehensively assess the impact of elements of cultivation technology on phenological, biometric, indicators, yield and quality of table beet products, development and improvement of elements of technology for their cultivation in the forest-steppe of Ukraine. This involves the use of highly productive varieties, the use of various effective biological products, is relevant for the spread and cultivation of table beets in the forest-steppe of Ukraine. Phenological observations of canteen beet plants showed that they developed differently and reacted differently in the phases of growth and development, depending on the introduced biological products. The technical ripeness phase began on days 121–129 and was longer than in the control. With the introduction of Solutin and Chlorella – 128–129 days, and in short - with the introduction of biological products Helprost vegetable, Helprost vegetable + Phytohelp, Solutin + Phytohelp – 121–125 days. It was proved that table beet plants differed in height, number of leaves, leaf blade area and their total area per hectare, which compared to the control were from the use of a tank mixture of biological products Helprost vegetable + Phytohelp – 28.3–28.7 thousand m2/ha, which is significantly higher than the control by 13.6–14.8 thousand m2/ha. The area of leaves was slightly lower as a result of the use of other drugs and mixtures – 21.8–22.6 thousand m2/ha. The use of a mixture of drugs Helprost vegetable + Phytohelp contributed to an increase in the mass of the root of table beets by 255–350 g, which is significantly higher than the control by 9–10 g. A positive effect on the yield of beetroot was shown by the vegetable Helprost preparation, as well as a mixture of vegetable Helprost + Phytohelp preparations, the use of which provided a yield of 52.4–63.8 t/ha. The use of a mixture of biological products Solutin + Phytohelp improves the appearance of the plant, increases resistance to harmful microorganisms, and the marketable yield increases to 26.0 t/ha and significantly exceeds the control by 3.2 t/ha.

Over the past 20 years, various scientists have conducted a number of researches on the effect of clipping before lambingon the wool productivity of sheep of different breeds and in different climatic conditions. The authors studied the effect of clipping before lambing on the milk production of ewes, studied the growth and development of lambs, the dynamics of live weight and the livability of young animals. The accumulated data allowed us to conclude that the use of clipping before lambing increases the productive performance of animals. However, these studies were fragmentary and did not have a systematic nature, so for these and other reasons they were not adopted by sheep breeders. The work on the infl uence of clipping before lambingon the wool productivity of the sheep of North Caucasian Meat and Wool breed has been carried out in the experimental division of the All-Russian Research Institute of Sheep and Goat Breeding. The purpose of the research was to determine the effect of late-autumn (November) insemination and clipping before lambing (3 weeks before lambing) of the sheep of North Caucasian Meat and Wool breed on the quality characteristics of the wool of ewes and their off spring. In accordance with the research methodology 2 groups of pregnant ewes have been selected, the formation of which has been carried out on the principle of analogues in age and live weight. In the 1st group (control) 100 heads were selected and have been clipping in the traditional terms after lambing (early June), in the 2nd group (experimental) 100 heads that were clipping three weeks before lambing (early April). It has been found in our studies that clipping ewes 21 days before lambing has a positive effect on the wool productivity of the resulting off spring. As the result of better growth and development of young animals, more intensively receive nutrients to the hair follicles, so most of them produce wool fiber.

A variety of different physical methods are used increasingly frequently to improve the quality of theseeds material. Numerous publications confirm the positive effect of, for example, the magnetic field witha frequency of 50 Hz on the germination of seeds. However, there are no significant reports regarding theimpact of NIR radiation on the growth and development of plants. To fill this gap the influence of three dosesof near-infrared seeds stimulation was tested under laboratory conditions. The power density was 6.9mW/cm2. The used seeds encompassed four parsley varieties: Konika, Osborne, Alba and Hanácká. Both the influenceof the used variety as well as the radiation dose on parsley germination were tested. The obtained resultsindicate that the stimulation affects the selected parsley varieties.
