Description
Elements of the cultivation technology of winter wheat variety called ‘Antonina’ with the application of different backgrounds of soil fertility, norms of fertilizers, system of plant protection from weeds, pests and diseases were studied. The studies are conducted in a polyfactorial stationary experiment: factor A - soil fertility; factor B - system of fertilizers; factor C - plant protection system; factor D - methods of basic soil cultivation. In the experiment four models of soil fertility levels were studied: А0 - the initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of litter manure); А2 - increased (doses are doubled); when А3 - high (tripled). Based on the studies it has been established that to obtain a stable yield of winter wheat, an increased dose of mineral fertilizers should be used, which also ensures high grain quality indicators. The maximum yield increase of 37% was achieved on varieties in comparison with extensive technology. A significant increase of the protein content in the grain from 12.8 to 15.3% and gluten from 22.0 to 27.8% was found in the intensive technology - triple doses of fertilizers (NPK) and the use of integrated protection against diseases, pests and weeds. The introduction of high doses of mineral fertilizers contributes to the accumulation in the soil and grain of nitrogen, and also reduces the content of copper and zinc

Description
The reaction of winter wheat cultivar ‘Antonina’ on the level of fertility and doses of fertilizers on crop productivity was studied. Investigations are carried out in multivariate 11 –course crop and grain-grass rotation stationary: factor ‘A’- the fertility of the soil; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil cultivation: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. On the basis of proven researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased and nitrogen - up to 140 kg per hectare. The increase in yield is due the rise of the quantity of grains per ear and weight of grain per ear

Description
The article is devoted to the various elements of the cultivation technology of winter wheat called Antonina with the application of different soil fertility backgrounds, fertilizer norms, and plant protection systems against weeds, pests and diseases. Investigations are carried out in a multivariate stationary experiment: factor ‘A’- soil fertility; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - medium (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil tillage: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. Based on examined researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased, by that, the high quality of the grain is provided

Description
The proposed agro technology for the cultivation of soft winter wheat contributes to the reproduction of fertility of leached Chernozem of the Western Ciscaucasia. As a result of application of fertilizers in the arable layer of soil hydrolytic acidity decreased by 21.8%, humus content increased by 10.3%, mobile phosphorus - by 54.8%, mineral nitrogen by 10.3% and potassium - by 9.6% compared to the control. Studied agricultural technology allowed to increase the yield of winter wheat to 81.8 kg/ha and protein to 15.3 per cent, of gluten, to 27.8%. We have noticed exceeded concentration of mobile phosphorus in the upper soil horizon (1.5 MРС) in the cultivation of wheat after alfalfa, which contributed to reduced grain yield. Under conditions of prolonged application of fertilizers and pesticides reduced the content of mobile forms of trace elements - copper and zinc. The content of mobile forms of Mn, Cu, Zn, Cr, Ni, Co, Pb and Cd below the limit values of environmental and Toxicological regulations clayey and loamy soils for agricultural purposes. The trend of accumulation of cadmium in the green mass of plants (~ 1.2 MPC) and winter wheat grain up to 1.5 MPC for baby food
