The influence of different agricultural technologies on
the yield of winter barley variety ‘Gordei’ was studied.
Economic evaluation was given to the researched
factors. The studies were carried out at the
experimental station of Kuban State Agrarian
University in the conditions of polyfactorial long-term
soil monitoring. The soil is represented by strongly
leached, light-clay black humus with an average
thickness of the humus horizon - 150 cm. It was found
that with the change of technology (fertilizer, tillage,
sowing method, means of protection) winter barley
yields increases to 50% in comparison with the
control. According to the analysis of bioenergetic and
economic evaluation it makes sense to use the variants
022, 111 and 222 at plowing, where the maximum net
efficiency ratio and net income are noticed
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
