EFFICIENCY OF FERTILIZERS APPLICATION ON SUNFLOWER CROPS ON BLACK LEACHED SOILS WITH DIFFERENT SOIL FERTILITY LEVELS

abstract 1381804025 issue 138 pp. 106 – 121 30.04.2018 ru 121
In the article we present the results of perennial researches on the influence of norms of fertilizers on growth and productivity of sunflower on Chernozem (Black soil) with different levels of fertility in the Central zone of the Krasnodar region. The improvement of nutritional status of plants promoted increase in leaf area of sunflower in the flowering stage from 20.1 to 30.8 thousand m2/ ha and more accumulation of dry substances and major nutrients in plant tissues throughout the growing season. The greatest influence on the content of nitrogen and phosphorus in the leaves of 56 – 64 and 50 – 58%, in stalks of 40 – 62 and 39 – 42%, in baskets 43 – 59, and 38 -68%, respectively, provided the rate of fertilizer. The yield of sunflower seeds in average for three hybrids (Kubanskiy 341, Triumph, Legion) evolved in experiment parcels from 25.5 to 33, 4 ac./ha. The highest productivity of this crop is obtained when a high rate of fertilizer (N80Р120) is applied on soil with a high level of fertility. The increase of seed yield compared to control was 7.9 ac./ha or 30.9 %. While increasing the level of soil fertility and fertilizer amount, oil content of the seeds decreased from 46.9 to 44.5%, but the yield of oil increased from 1.20 to 1, 47 T/ha due to the growth of productivity

GROWTH, DEVELOPMENT AND YIELD OF WINTER BARLEY IN THE CENTRAL ZONE OF THE KRASNODAR REGION

abstract 1151601037 issue 115 pp. 594 – 612 27.01.2016 ru 362
The article deals with a combination of different methods of cultivation of winter barley on the background of plowing, and their impact on growth, development and crop yield. The main technological factors allowing implementing the biological potential of culture are adaptive variety, quality seeds, predecessors, sowing and harvesting, fertilizer, soil fertility, crop care, including protection from weeds, pests and diseases. Barley is the culture of versatile use, which is grown for food and feed purposes. Intensification of cultivation methods of this phenomenon is essential and significantly affects the grain yield of this crop. Under the natural fertility of the soil and favorable weather conditions for black earth of Kuban it is possible to get 3,0-3,5 tons per hectare of winter crops of grain, and this requires the creation of an optimal diet, because one of the main factors affecting the productivity of field crops, including one phenomenon are fertilizers. In addition, the level of soil fertility and protection system of weeds, pests and diseases has great importance. Since these types of issues are relevant for agriculture, we have carried out studies to identify the optimal combination of different methods on growth, development and productivity of a single phenomenon

PHYTO-SANITARY CONDITION OF CROPS OF WINTER BARLEY WHEN GROWING USING DIFFERENT TECHNOLOGIES

abstract 1151601038 issue 115 pp. 613 – 631 27.01.2016 ru 340
The article presents the biennial data on infestation of winter barley infected with his disease and pests, depending on fertilizer rates, the main method of tillage and plant protection. Weeds are one of the most highly potent factors that reduce the productivity of plants. System of agronomic plant cannot increase the productivity of plants, if it contributes to impurity of crops. In the studied years, the most common weeds at the recommended tillage were dead nettle, cleavers, chickweed, field bindweed. At zero processing - foxtail, poppy, wild oats, Leptospermum, dead nettle, veronica. The use of biological and chemical plant protection products reduced the degree of expansion and development of disease

PRODUCTIVITY OF GREEN MASS OF ALFALFA DIFFERENT YEARS OF LIFE ON LEACHED CHERNOZEM IN CONDITIONS OF KUBAN

abstract 0931309065 issue 93 pp. 949 – 969 30.11.2013 ru 940
The article deals with the various technologies of alfalfa 1, 2, and 3 years of life with different backgrounds soil fertility, fertilization rates, protection from weeds, pests and diseases at recommended and zero tillage

PRODUCTIVITY OF WINTER BARLEY IN LEACHED CHERNOZEM CONDITIONS OF KUBAN

abstract 1141510112 issue 114 pp. 1550 – 1568 30.12.2015 ru 654
The article discusses the various technologies of cultivation of winter barley at two ways of main tillage (recommended and zero-level) with different backgrounds of soil fertility, fertilization rates, protection from weeds, pests and diseases. Consistent improvement of soil fertility and other fertilizers resulted in an increase in crop productivity. Nutrition is the basis of life of a living organism, including plants. The value of crop yield and its chemical composition depend on the conditions of nutrition. It is achieved with the optimum combination of light, heat, air, water, food, etc. In this connection, in the development of methods of cultivation of this crop, we may not only increase the yield of grain, but also pay due attention to the quality of cultivated products. Thus, studies in the experiment showed that the intensification of cultivation technology of one phenomenon substantially and significantly affects the productivity of the given culture

THE INFLUENCE OF DIFFERENT AGRICULTURAL TECHNOLOGIES ON THE CONTENT OF THE MAIN NUTRIENTS IN THE SOIL UNDER LUCERNE OF 1 YEAR OF LIFE ON THE BLACK LEACHED SOIL OF WESTERN CISCAUCASIA

abstract 0931309067 issue 93 pp. 982 – 995 30.11.2013 ru 1113
In this article, we review the influence of different production technologies for nitrogen, phosphorus and potassium in the soil under alfalfa, and the impact of culture on the accumulation of nitrogen in the soil
