CROP YIELD AND GRAIN QUALITY OF ANTONINA WINTER WHEAT IN LEACHED BLACK SOIL UNDER THE CONDITIONS OF THE WESTERN PRE-CAUCASIAN REGION

abstract 1291705098 issue 129 pp. 1353 – 1370 31.05.2017 ru 251
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

DEPENDANCE OF YIELD AND GRAIN QUALITY OF THE WINTER WHEAT FROM CULTIVATION TECHNOLOGIES IN LEACHED BLACK SOIL UNDER THE CONDITIONS OF THE WESTERN PRE-CAUCASIAN REGION

abstract 1321708117 issue 132 pp. 1425 – 1442 31.10.2017 ru 232
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

WINTER WHEAT PRODUCTIVITY ON THE LEACHED BLACK HUMUS IN THE CONDITIONS OF THE WESTERN PRE-CAUCASIAN REGION

abstract 1251701049 issue 125 pp. 724 – 737 31.01.2017 ru 355
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
