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

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 longterm 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 chernozem leached superheavy light-clay 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 influenced the mass of grain from the spike

The article studies the effect of various agricultural practices on the yield of two sunflower hybrids (Fortimi and N4LM 408) in the experiment. The studies were carried out in the central zone of the Krasnodar Region on the experimental fields of the JSC "Agrocomplex", Vyselkovsky district in 2018-2019. The experience was laid down according to the triple experience scheme (factor A - the primary soil cultivation techniques; factor B - sunflower hybrids; factor C - herbicides). It was found that with the change of technology (the method of soil preparation and the use of herbicides), the weed infestation of crops changed and a minimum number of them was noted on the variants where postemergent herbicides were used (Euro-Laytning and Hermes). The maximum yield was obtained using chisel and disk plowing with the treatment of sunflower crops with the herbicides Euro-Light and Hermes. There was an increase in yield compared with plowing and these changes are mathematically valid
