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.

Purpose: to analyze the experience of applying mineral and organic fertilizers on dry and irrigated lands for the main agricultural crops. The overview of scientific research results, literature sources on applying a fertilizer system in agriculture, in which nutrients necessary for agricultural crops are introduced into the soil during the most critical periods of growth and development are presented. This paper considers the use of fertilizers, taking into account the utilization rates of available forms of nitrogen, phosphorus, potassium and other elements necessary for plants from fertilizers and the root layer of the soil, clarifies the need to compensate for the removal of nutrients by the vegetative and generative parts of the crop, the rate of consumption of mineral nutrition elements by agrocenoses. The timing and methods of using organic and mineral fertilizers depend on the granulometric composition of the soil, the predecessor, the level of groundwater occurrence, the agrochemical properties of soils, the efficiency of the drainage network, weather and climatic conditions, the growth and development phase of the cultivated crop. Conclusion. The study of the works of domestic and foreign scientists on the timing, norms, types and methods of applying mineral and organic fertilizers for various agricultural crops cultivated on dry and irrigated lands, and the analysis of the studies allow us to conclude that in the conditions of digitalization of agricultural production, there is no consensus about the systems the use of mineral and organic fertilizers in the conditions of precision (precision) farming. Research in this area is promising at the present time and in the near future, especially when using modern means of diagnosing deficiencies in plant nutrients.

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%.

<p>Light energy is one of the most important factors regulating the growth and development of plants. In greenhouses and other controlled- environments in which the natural radiation intensities are often low, plant production relies on supplementary lighting to optimize the photosynthesis, increase production levels, and enable year-round production. For a long time, the research related to artificial lighting sources focused on the optimization of the efficiency of use for photosynthesis. The quality of light in plant production has been widely addressed only recently with the development of advanced LED technology that is energy efficient and enables the control of the spectral composition of light. Red and far-red light are sensed by the phytochromes that trigger several morphological and developmental processes that impact productivity and yield quality. Thus, to efficiently exploit all the advantages of LEDs and to develop LED arrays for specific plant applications, it is essential to understand thoroughly how light quality influences plant growth and development. This paper presents an overview of the recent developments in light quality manipulation, focusing on far-red light and the R: FR ratio, to improve yield and quality of products and to manage plant architecture and flowering in vegetable and ornamental horticulture.</p>

Definition Of

The article deals with the influence of planting depth of potato tubers on productivity, structure, quality of products and the marketability of potato crop in the conditions of the Chuvash Republic. The depth of seeding of tubers has a direct impact on all processes of growth and development. The more favorable the complex of conditions in the zone of placement of planted tubers, the faster they germinate and give early and amicable shoots, the more successful the further development of the potato plant and the formation of the crop. Determining the dependence of the potato tuber planting depth on the productivity, structure, quality of the products and the marketability of potato plants hinders many causes that are directly related to the growth and development of potato plants, as the productivity of potato plants is significantly increased by optimizing the priority conditions that are necessary in potato cultivation, when there is an increase in all indicators of photosynthetic activity of potato plants. The density of plants should be such that plants could form a powerful leaf surface, a root system and make the best use of solar energy and soil nutrients [11 12]. In numerous studies by our and foreign authors on the definition of optimal areas of potato nutrition, the following general provisions are present: late varieties, that develop a powerful top, are placed less often, early - thicker; the less moisture in the soil, the less should be the density of planting [6]. In this study, in order to determine potato productivity, we first of all determined crop yields, structure, product quality and marketability of tubers. Norms of planting can be determined depending on the density of the stalk. The high density of plant standings promotes acceleration of passage of development phases by plants, early tuber formation and ripening of a potato [3,4,5,7,8,9]. Thus, in the experiments, carried out by V.T. Spiridonov (1972) in the Chuvash Agricultural Institute in the variant where the planting was carried out according to the scheme of 70x30 cm, the entry of plants into the mass flowering phase was noted 2-3 days earlier than when planting according to the scheme of 70x35 cm. Reduction of the distance between tubers to 25 cm accelerated the development of plants 5 days.

Effective Use

In the effective use of saline soils, it is advisable to plant sunflower, corn, beetroot and other crops resistant to soil salinity. At the same time, it is necessary to plant domestic and imported crops such as millet, amaranth, and African sorghum as secondary crops in these soils. These crops, even in saline soils, can contribute to the development of livestock in Uzbekistan by producing 400-500 q/ha, and even higher yields. Most importantly thousands of hectares of land that have fallen out of agricultural use will be re-introduced into the farming system. This is one of the current issues of today. In solving this problem, the resistance to salinity, yield and product quality of agricultural crops (alfalfa, sunflower, white sorghum, sorghum, beet) grown on weak, moderate and strongly saline soils are studied and scientifically substantiated. Technologies for growing these crops will be developed depending on soil and climatic conditions and salinity levels.

Blackberries play an important role in human nutrition, due to the elevated content of certain bioactive compounds including ascorbate, anthocyanins, phenolic acids, carbohydrates, and proteins. Blackberry Rubus glaucus from Colombian Andes has a high demand on regional and international markets and there is much interest in its cultivation to increase the com mercial offer. In four blackberry producing municipalities of Cundinamarca province, fruits were harvested for different quality tests based on the availability of hydric resources in the zone and their influence on fruit characteristics according to the precipitation of each zone, since the crops did not have an irrigation system. The variables, such as size, fresh weight, tex ture, pH, titratable total acids (TTA), total soluble solids (TSS), and color were evaluated to compare the quality of the fruits between the municipalities, finding that fruits from Silvania had the greater size but, in turn, were the least consistent. El Colegio zone presented the sweetest fruits and together with Pasca had the highest acidity percentage. The color of Pasca and Silvania fruits was the most attractive for commercialization parameters. These parameters, even when management and agro-climatic conditions between municipalities were very similar, allows knowing the positive attributes and determine the factors that need to be improved and to project on a short-term future productions acceptable on the international market.
