  Description

  Competitive relations between various kinds of weeds in sunflower crop and influence of connatural factors on its constipation are considered. Specific weight of each kind of a weed and its change throughout a vegetative period, and also influence of gramineous weeds on efficiency of breeds and hybrids is defined. The economic threshold of injuriousness of gramineous weeds in sunflower crops is defined

  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

  06.00.00 Agricultural sciences

  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
