In the article, the review of the results of test of 10 grade samples in five differing eco-geographical zones throughout six years is given. Their adaptive parameters are defined and the assessment of environments of test as a background for seed growing of beans is made
There was given the review of the results of the study
in the arid zone of Central Ciscaucasia, the influence
of planting terms and presowing seed treatment by the
drug called "TMTD-plus", containing the growth
stimulator Krezatsin in its composition, on the
development of corn hybrids of different maturity
groups of the selection of Krasnodar Research Institute
of Agriculture named after P.P. Lukyanenko (Ross
199, Ross 299, Krasnodar 382 and Krasnodar 410) and
the All-Russian Research Institute of Corn (Mashuk
170, Newton, RIC 345 and Eric), as well as middlematurity
population Rossiyskaya 1. The studies were
conducted in accordance with the thematic plan of
scientific researches of the chair of crop and forage
production of the Stavropol State Agrarian University.
The soil surface was presented as southern black earth.
The technology of growing of maize on the
experimental plot corresponds to the standard one for
the present area and cultivar. The predecessor is winter
wheat. Sowing was performed in three terms. The first
(early) sowing term was carried out at t = + 7 ... +8 °
C. The second (recommended) - when t = + 10 ... + 12
° C. The third (later) sowing time was carried out at t =
+15 ° C. The plant density: early-maturing hybrids –
70 thousand pieces/ha, is mid-maturing ones – 60
thousand pieces/ha, middle-ripe – 50 thousand
piece/ha, middle-later ones – 45 thousand pieces/ha.
The scheme is single-row, with spacing of 70 cm. The
application of the studied drug TMTD-plus helped to
reduce the growing season of maize plants for one -
two days. Thus, changing the sowing terms of maize
hybrids and populations, we can largely control the
development of plants changing the length of the
growing season to two weeks and form a harvesting
conveyor, thereby reducing the intensity of field work
This article provides an overview of results of the conducting surveys on screening and saving gene pool of indigenous grape varieties in the Republic of Abkhazia, which contributed to detection and identification of the 15 previously described in the literature of Abkhazian native grape varieties
The article gives an overview of the results of a study of the growth and development of corn in the conditions of the Northern zone of the Krasnodar region depending on the density of plant standing and seed treatment. The object of the research was an early-ripe hybrid of Ross 199 corn. Two factors were studied in the experiment: factor A - plant stand density (60, 70 and 80 thousand units / ha), factor B - seed dresser (Maxim XL (k) and Maxim Quatro). The subject of research is included in the thematic plan of scientific research of the Department of General and Irrigated Agriculture of KubSAU. The total area of the plot is 1008 m2, the accounting area is 672 m2. The number of rows in the plot is only 8, including accounting - 4. plots The plots are placed systematically. Repeating: 3-fold. The predecessor is winter cereal crops (wheat). The counts and observations in the experiment were carried out according to generally accepted methods. The studies have established that the duration of the interphase and vegetation periods of corn plants depended on the density of plant standing, and with the thickening of crops, it decreased, and protectants did not affect this indicator. In all phases of determination, the maximum height of corn plants was noted with a plant standing density of 80 thousand units / ha. The studied dressers Maxim XL and Maxim Quattro had practically no effect on height. The diameter of the second internode decreased with thickening of the crop
The article provides an overview of the results of a study of the effect of nitrogen fertilizers (sowing and top dressing) on the growth and development of sugar corn plants. The object of research was the mid-early hybrid of corn called Krasnodar Sugar 280 NE (FAO 280). In the experiment, 2 factors were studied: factor Ā - sowing nitrogen fertilizer (b / b (k), 15 and 30 kg.d.v / ha), factor B - root nitrogen top dressing (b / b (k), 15 and 30 kg.dv./ha). The total area of the plot is 20 m2, the accounting area is 10 m2. The number of rows in the plot is only 4, including accounting - 2. The plots are systematically placed. In the fall, the main fertilizer was applied in the background at a dose of N30P60K60, under plowing. Repeating four times. The predecessor is winter wheat. The counts and observations in the experiment were carried out according to generally accepted methods. Studies have established that the phases of “seedlings” and “5-6 leaves” did not depend on nitrogen fertilizers. The “panicle panning” phase in the variants with the introduction of nitrogen occurred 2 days later, and the phase "milk ripeness on the cob" - for 1 day. The height of the plants of the control variant was 202 cm. With an increase in the dose of nitrogen, the height of the plants of sweet corn increased. The maximum (12 cm higher) plant height was on the option using N30 for sowing and root dressing
There were reviewed the results of the study of the
dependence of main of phenological phases of
development of corn hybrids of different maturity
groups of selection of Krasnodar Research Institute of
Agriculture named. P.P. Lukyanenko in a zone of
sufficient moisture of Central Ciscaucasia (Ross 199,
Ross 299, Krasnodar 382 and Krasnodar 410) and the
All-Russian Research Institute of Corn (Mashuk 170,
Newton, RIC 345 and Eric), as well as early-middle
middle Rossiyskaya 1 from the change of average daily
air temperature at different dates of sowing and preplant
seed treatment by the preparation "TMTD-plus"
containing the growth promoter called Krezatsin in its
composition. The studies were conducted in
accordance with the thematic plan of scientific
researches of the department of crop and forage
production of Stavropol State Agrarian University. The
technology of maize growing on the experimental plot
corresponds to the standard technology for this area
and culture. The sowing was performed in three stages.
The first (early) sowing period was at t = + 7 ... +8 ° C.
The second (recommended) – was at t = + 10 ... + 12 °
C. The third (later) sowing period was carried out at t
= +15 ° C. There was identified a high inverse
correlation between the average daily air temperature
and the duration of the intraphase periods of maize
propagation. Thus, at the shifting of maize sowing
dates with the second half of may on the second half of
April, the optimization of heat regime in the generative
period and rising of efficiency of use of thermal of
resources of the region. There was marked the
acceleration of development of corn seedlings when
the average daily air temperatures was up to +12 ° C
at the samples with the application of the disinfectant
TMTD-plus
The article gives an overview of the results of studies on indigenous grape varieties of the Republic of Abkhazia and the identification of their agro-biological characteristics
The article presents the results of studies on the influence of mineral fertilizers and basic tillage in the technology of cultivating winter barley on its agrophysical properties. Object of research - plants of winter barley cultivar called Rubezh. Soil - typical low-humus heavy-duty leached chernozems. In the experiment, the influence of two factors on the formation of the productivity of winter barley was studied. Factor A - the method of primary tillage: option 1 (A0) - dump plowing to a depth of 20-22 cm (control); option 2 (A1) - chisel for 20-22 cm; option 3 (A2) - disk peeling at 8-10 cm; option 4 (A3) - zero treatment (direct sowing). Factor (B) - fertilizer rate: option 1 (B0) - without fertilizing (control); option 2 (B1) - recommended norm N40P40 + N20; option 3 (B2) - double norm N60P60 + N40. According to the data of our experiments, the general orientation in the technology of cultivating winter barley has been revealed, during the entire growing season, the height of its plants decreases while the tension of its main processing decreases - from 89.6-90.3 cm for deep processing to 87.7 cm for surface processing and up to 73.7 cm at zero. Moreover, the type of tillage did not affect the stem of winter barley plants of the Rubezh variety. At the same time, on all tillage options, one can notice the dependence of the height and density of the stand on the dose of fertilizer application - from 80.6 cm in the control to 84.4 cm at the recommended dose of mineral fertilizers and up to 91.4 with a double. It was also noted in relation to the density of plant standing - from 335 pcs / m2 in the control to 358 pcs / m2 with the recommended dose of mineral fertilizers and up to 376 pcs / m2 with a double
