Description
There was given a review of the results of the study in the conditions of sufficient moisture of Central Ciscaucasia, the influence of planting terms and presowing seed treatment by the drug called "TMTDplus", containing Krezatsin growth stimulator 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 middle- maturity 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 of the experimental station of StavrGAU was presented as leached black soil. 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, middleripe – 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 - four 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

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

INFLUENCE OF BASIC TREATMENT ON AGROPHYSICAL PROPERTIES OF SOIL IN SUNFLOWER CROPS
Description
The article presents the results of studies on the influence of the main tillage in the technology of cultivation of sunflower on its agrophysical properties. The object of the research was sunflower, the Vulkan variety, the predecessor was winter wheat. The soil was superpowerful low-humus typical leached chernozem. The studies were carried out in a stationary experiment on the basis of the experimental field of the department of general and irrigated agriculture of KubGAU in accordance with generally accepted methods for experiments with grain crops. Variants of experience (basic tillage): Option 1 (A0) - dump plowing to a depth of 25-27 cm (control); option 2 (A1) - chiseling 25-27 cm; option 3 (A2) - disc peeling at 8-10 cm; option 4 (A3) - zero treatment (direct seeding). On the basis of the conducted research, a general trend of agrophysical soil deterioration during the entire vegetation period of sunflower development and with a decrease in the intensity of the main tillage in the technology of its cultivation is revealed. So, the soil density was minimal, and the total porosity and soil moisture, as well as the reserves of productive moisture were maximal when carrying out land plowing at a depth of 25-27 cm to the main tillage. 25-27 cm) slightly worsened these figures. Conducting in the main tillage only surface disc peeling to a depth of 8-10 cm led to a further deterioration in these indicators. And in the last place there was the option where the soil was left without primary treatment under direct sowing of the crop (the variant of zero tillage). And just before harvesting sunflower (September), zero tillage provided the highest levels of soil moisture and reserves of productive moisture

INFLUENCE OF BASIC TREATMENT ON AGROPHYSICAL SOIL PROPERTIES IN CROPS OF WINTER BARLEY
Description
The article presents the results of studies on the influence of the main tillage in the technology of cultivating winter barley on its agrophysical properties. The object of research was winter barley, sort Rubezh, the predecessor - winter wheat. Soil - heavy duty, low humus, typical leached chernozems. The studies were carried out in a stationary experiment on the basis of the experimental field of the Department of General and Irrigated Agriculture at KubSAU in accordance with generally accepted methods for experiments with grain crops. Scheme of experience (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). Based on the research, a general orientation is revealed in the technology of cultivating winter barley to reduce the agrophysical indicators of the soil throughout the growing season of the development of its plants while lowering the tension of its main processing. So, the density of the soil was minimal, and the structure and moisture of the soil, as well as the reserves of productive moisture were maximum on the option with dump plowing to a depth of 20-22 cm. Conducting deep loosening at the same depth (chiseling by 20-22 cm) somewhat worsened these parameters . Implementation of disk peeling in the main tillage (by 8-10 cm) contributed to the deterioration of these parameters. The option of zero tillage was in last place according to these indicators. And only before harvesting, zero tillage contributed to the formation of higher soil moisture and productive moisture reserves

INFLUENCE OF BASIC PROCESSING AND MINERAL FERTILIZERS ON AGRIBIOLOGICAL INDICATORS OF WINTER BARLEY
06.01.01 General agriculture, crop production (agricultural sciences)
Description
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
