abstract 1191605040 issue 119 pp. 553 – 566 31.05.2016 ru 672
In the article there were given the results of researches for 20110–2012 obtained of many years stationary experience of the chair of general and irrigated land management of Kuban State Agrarian University on study of main soil treatment influence and doses of mineral fertilizers under soy beans on dynamics of moisture in soil and efficiency of its use by this cultivar. There was determined that from all studied variants the ploughing on 20–22 cm led to the higher accumulation of moisture for autumn-winter period. The decrease of productive moisture reserves on 6-9 % was observed on the types with surface treatment and direct sowing. The increase of soil treatment depth and doses of mineral fertilizers promoted to the better accessibility of moisture during vegetation period and correspondently to their greater expenses. Moreover, there was revealed the more rational use of water by soy beans under mouldboard soil treatment and introduction of mineral fertilizers in the dose of N90P120, it discovers the high effectiveness of present agricultural methods. The highest productivity of soy beans in the experience was achieved by means of ploughing on 20–22 cm and introduction of mineral fertilizers as a main type of soil treatment

abstract 1191605080 issue 119 pp. 1134 – 1158 31.05.2016 ru 373
Limited resource of irrigation water in the South of Russia is a particularly actual task in the production of moisture-loving crops, such as rice. To solve the problem of rational use of water when watering is not possible without the organization of an automated water distribution. As it was shown by the analysis of tools and technologies of regulation of water supply, the most promising, form tested and used, can be tape regulators of flow and water level. They have a simple construction diagram, unpretentious in operation. However, we have identified a fault – unregulated leaking, not fully covered through the bore, which in turn increases the uncontrolled consumption of irrigation water. To solve this problem we propose a number of designs, protected by patents of the Russian Federation, having special fixture to ensure unauthorized leaks, even in a state almost close to the fully closed opening expiration from the regulator. The article comprehensively considers hydraulic studies of controller initially, without any additions that contribute to the problem of eliminating leakage. The proposed study with the analysis of the distribution of velocities and pressures in the design of belt regulator, will allow you to have the basic reference model against which it will be possible to analyze the degree of influence of constructive-technological changes at the work the newly developed devices. For this, we modeled tape controller in the software package FreeCАD version 0.15, when using SAE - system FlowVision. The task of modeling water flow were solved in flat statement, including the moment of full closing of the belt passage opening of the regulator. For plotting surfaces, lines, levels and cross-section response functions, we used a software package wxMaxima. The results obtained allowed a comprehensive analysis of the work tape of the locking device, hydraulically actuated device in all modes of the major factors and, in the future, will help to address the issue of studying the impact of introduced technological changes in the design of controllers

abstract 1191605087 issue 119 pp. 1268 – 1277 31.05.2016 ru 740
The researches were about availability of the appliance of some physiology active matters – aminoethoxyvinylglycine (AVG) and melafen for optimization of yield formation for orange and apple trees. Field researches were conducted in 2011-2012 in commercial orchards in the region of Gingin in the Western Australia (climate of the region – Mediterranean, the soil – sandy) and in 2015-2016 in apple orchards of the botanical garden of Kuban State Agrarian University (climate of the region - moderately continental), started in 2006. The article shows expediency of using inhibitor biosynthesis of ethylene of AVG at a concentration from 20 to 60 mg /l when the orange fruit size was 3.0 cm, and the growth regulator "Melaphen" (concentration 1˟10- 9 М) in the second half of the vegetation period of apple plants (for 45-50 days before harvest). The use of treatments in these terms reduces pre-harvest fruit drop and thus increase the economic productivity of fruit trees (apple in - up to 11%). It is noted that a variety of orange called Washington Navel is more responsive to the increased concentration of AVG, than the variety of Lane Late (optimal concentration of 60 and 20 mg / l, respectively). We have shown a wide spectrum of action of the treatment "Melaphen" on apple plants. Along with the retention of the fruit on the tree, it enhances the activity of plant growths in summer and some weakening concerning tabs flower buds as well as the displacement of their development. However, the use of melaphen in this period increases the efficiency of the formation of various parts of flowers and fertilization in the next season. With such results of the adjustment processes of vegetative growth and generative development of plants under the influence of physiologically active substances, it will ensure the formation of relatively high and regular yields of fruits

abstract 1181604005 issue 118 pp. 87 – 112 29.04.2016 ru 859
The article presents the results of studying the effect of different lengths of fruit vines with the same load wintering buds of bushes on the yield and quality of Moldova grapes. It was found that the biological indicators of fruiting Moldova grapes improved by lengthening fruit vines, taking into account weather conditions. Shortening the vines increases germination and fruitfulness degree base buds and reserve buds. Productivity is increased by lengthening fruit vines. It is determined by the degree of fruitfulness buds of the vine, the development of floscules of wintering buds, bunch and berries weight, number of berries in bunches. The optimum is pruning vines to 10-12 buds. Harmonious taste, weight of bunches and berries, transportability factor fixed high yield of grapes standard (85,6-86,4%) with different length of fruit vines. The highest productivity of leaves makes pruning fruit vines to 10-12 buds. The strength of shoot growth and volume growth of bushes reduced at an elongation of the fruit vines. The more moderate growth of shoots observed at long (10-12 buds) pruning vines. There is no significant difference to the degree of maturation of shoots with different length vines. In order to increase the yield of Moldova grapes in the central zone of the Krasnodar region expedient cut fruit vines to 10-12 buds

abstract 1181604043 issue 118 pp. 758 – 772 29.04.2016 ru 552
In the leached black soils of the foothill zone of the Kabardino-Balkarian Republic on the territory of training experimental plant of FSBEI HE Kabardino-Balkarian state agricultural university named after V.M. Kokova we have studied the effect of soil and climatic conditions of area of cultivation and application of micro – macro fertilizers, plant growth regulators and biological products on the crops of lentils, their impact on the efficiency and quality. It is proved that in general, the natural conditions of the foothill zone are favorable for cultivation and obtaining high yields of major crops. The analysis of meteorological conditions of the area (typical for the whole area) shows that there are great reserves and opportunities to obtain high and stable yields of lentils grains. These morphological, genetic and agrochemical parameters of leached chernozem growing zones suggest the soil favorable to the growth and development of lentils. On average, during the years of studies, the number of plants on which we had marked tubercles, on the example of Rauza varieties in the background variant, was 63.7%; the use of the drug called Agropon C in combination with sodium selenite increased by 15.2% the number of plants with root nodules. Increasing the number of plants with root nodules was accompanied with increasing the number and weight of nodules per plant by 8.1 pc. and 10.1 mg. respectively. The highest yield - 2.66 t/ha under experimental conditions was obtained in the form of joint use of the drug Agropon C and sodium selenite with a seeding rate of 2.2 million viable seeds per hectare, which is higher than the reference version for this seeding rate by 0.46 t/ha or 17.3%. The maximum value indicators of protein content in the seeds and collecting the protein per unit area reached with the use of joint application of Agropon C and sodium selenite, where we achieved the seeding rate of 2.2 million of germinating seeds per hectare and made up 29.6% and 787 kg/ha, respectively
