CROP YIELD OF WINTER BARLEY GRAIN WITH THE APPLICATION OF VARIOUS GROWING TECHNOLOGIES

abstract 1371803021 issue 137 pp. 106 – 122 30.03.2018 ru 37
The experiment considered the influence of different methods of agricultural technologies on the yield of winter barley in the dependence of the investigated factors. The studies were carried out at the experimental station of Kuban State Agrarian University in the conditions of multifactorial long-term soil monitoring. The experiment was carried out in a typical 11-field grain-grass-tillage crop rotation with the following alternation of crops: alfalfa, alfalfa, winter wheat, winter barley, sugar beet, winter wheat, corn for grain, winter wheat, sunflower, winter wheat, spring barley with sowing of alfalfa. Stationary experience is represented by the following factors: the level of fertility (factor A); fertilizer system (factor B); plant protection system (factor C) and methods of basic soil cultivation (factor D). The relationship between the influence of the soil fertility level, fertilizer norms, plant protection products, the soil cultivation system and yield, and the crop structure of the perspective winter barley variety ‘Gordey’ were determined. The soil is leached super-heavy light-clay chernozem with an average thickness of the humus horizon - 150 cm. It is found that fertilizer, soil treatment, seeding method, protective means increase the yield of winter barley and positively influences the elements of the yield structure. The yield increase in comparison with the control changed from 10.4 to 26.8 c / ha. The statistical processing data show that the fertilizer system (35.8%) and soil cultivation (27%) had a certain influence on the number of productive stems; the fertilizer system (44.6%) influenced the spike size, the fertilizer system (28%) and the tillage (32.8%) had influence on the amount of grain in the spike and also influenced the mass of grain from the spike

INFLUENCE OF A WAY OF PROCESSING OF THE SOIL ON EFFICIENCY OF SUNFLOWER

abstract 1361802015 issue 136 pp. 169 – 178 28.02.2018 ru 32
This article discusses the results of a study to determine the impact of different primary tillage to sunflower yield. The task of the research was to determine the impact of primary tillage in the agrophysical and agrochemical soil properties. It has been established that the content of productive moisture during the growing period in 0-100 cm soil layer does not depend on the method of processing. Surface treatment of the soil did not have negative effects on soil properties and its agrophysical structure in comparison with moldboard ploughing. . When dump processing improves the density of the soil, accumulates more moisture in the autumn winter period, reduces the weediness of sunflower perennial weeds. Productivity in contaminated areas increases by 3.3 - 5.4 c / ha. On weed-free crops, the yield increased by 2.5 - 3.5 c / ha, due to the improvement of the physical parameters of the soil

THE EFFECTIVENESS OF VARIOUS SOIL TREATMENTS AND HERBICIDE ON YIELD OF WINTER WHEAT UNDER THE CONDITIONS OF TERRAIN-EROSIVE AGROLANDSCAPE

abstract 1381804019 issue 138 pp. 91 – 105 30.04.2018 ru 20
Plants of winter wheat suppress weeds quite well, however, the use of herbicides is required, which prevents the new clogging up of soil. Under surface tillage it was observed a greater spread of weeds than under mold-board plowing. Introduction of the herbicide Lancelot regardless of ways of tillage has reduced this rate in 5.8 times. An important means of regulating of vital functions of soil microflora is tillage. 40% of all expenses ac-counted for the soil treatment required for cultivation of crops. Therefore it is important to study the effect of tillage on the course of microbiological processes in the upper 0-30 cm layer. The intensity of the decomposition of plant material by linen cloths method objectively reflects the status and activity of soil microflora. One of the signs of cultural soil condition is its ability of nitrification. Nitrification process is particularly slow in early spring, because this time the microbiological activity is weak because of low soil temperature. When the soil is progressing the number of nitrates increases and reaches its peak in summer, after that the process is fading. Studies have shown that under surface tillage, microbiological processes of decomposition of cellulose and the ability of soil nitrification compared with moldboard plowing are higher. The components of yield structure show features of yield formation. Tillage did not have an essential effect on crop structure elements. Application of herbicide Lancelot has significantly increased the number of productive stalks (7.3-10%) and mass of 1000 grains on 1.8 g or 4.5%. Grain yield of winter wheat did not depend on the primary tillage (57.5-56.5 kg/ha). Application of herbicide Lance-lot has allowed to receive allowance (on average for 2 years) 5.0 kg/ha. Grain quality indicators of winter wheat depend both on the hereditary traits and preferred growing conditions. The amount of gluten is not dependent on the main tillage, while the introduction of herbicide has increased gluten to 1.4%. Calculation of economic and bio-energy efficiency showed that the use of surface treatment in the cultivation of winter wheat on soil ordinarily is worthwhile
