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

abstract 1371803021 issue 137 pp. 106 – 122 30.03.2018 ru 2
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 1
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

INFLUENCE OF TILLAGE AND CHEMICAL WAY TO CONTROL WEEDS ON WINTER WHEAT PRODUCTIVITY UNDER THE CONDITIONS OF THE PLAIN-EROSIVE AGROLANDSCAPE

abstract 1341710002 issue 134 pp. 14 – 26 29.12.2017 ru 73
This article discusses the results of the study to determine the impact of different primary tillage and herbicide against weeds in winter wheat agrocenosis. The task of the research was to determine the impact of primary tillage (moldboard plowing and surface treatment) factor A and herbicide (Lancelot) factor B on the agro-physical and agrochemical soil properties. It has been established that the content of productive moisture during the growing period of winter wheat in 0-100 cm of soil layer didn’t depend on the method of tillage. Introduction of herbicide Lancelot boosted the moisture reserves in soil compared to the control type, in the herbicide-free type the weeds absorb the large amounts of moisture. Surface soil treatment did not have negative effects on soil agro-physical properties and its structure in comparison with moldboard plowing. Number of agronomically valuable aggregates on moldboard plowing is 85.2 - 87.5%, on surface one is - 86.2 87.5%. Density of composition and waterproof aggregates under surface treatment didn’t defer to tillage. Accumulation of wet and dry mass by weeds regardless to the way of soil tillage declined to a minimum when introducing the herbicide Lancelot. The high yield of winter wheat was obtained on this type. Mathematical processing results have shown that due to factor A (main soil tillage) to moldboard plowing the average productivity is 57.5 kg/ha, on surface one is 56.0 kg/ha, i.e. the difference between treatments is 1.5 t/ha (with NSR05 on factor - 2.9 t/ha) is insignificant. To factor B (herbicides) on control the productivity is 54.5 kg/ha, introduction of Lancelot increased the productivity to 59.5 t/ha, i.e. the increase was 5.5 kg/ha at NSR05-by the factor B-2.9 t/ha, i.e. is significant. Thus, the present soil treatments had no effect on yield of winter wheat in ordinary black soil. The use of herbicide Lancelot has produced the harvest increase in 0.5 t/ha on average for 2 years
