abstract 1201606088 issue 120 pp. 1322 – 1336 30.06.2016 ru 159
The influence on the predecessor, on the time of sowing and various mineral nutrition levels, on the productivity of seven cultivars of winter soft wheat of Krasnodar Agricultural Research Institute selection was investigated. On the basis of the obtained experimental data and production audit it was found that all studied cultivars under the total complex of cultivation technological methods are able to form the yield of 6-7 t / ha with the payment of one kg of active ingredient of fertilizer by the grain within 6.50-9.86, and 8.56- 10.71 kg. Soil was ordinary chernozem with a low humus content powerful humus content, depending on the power of backgrounds in the arable (0-30sm) soil layer is 3,95-4,00%, of mineral nitrogen is 5,9-8,3 mg / kg of soil, mobile phosphorus is 22,4 - 26,6 mg / kg of soil, of exchangeable potassium is 330-360 mg / kg of soil. Predecessors are winter wheat, sunflower, white mustard cultivated on seeds. The main tillage is resource-saving with the mulching of 0-10 cm layer. Studied sowing terms are the 20th of September, the 1st and 10th of October. The backgrounds of mineral nutrition: 1-without fertilizer N0P0К0; 2-minimum dose of complete mineral fertilizer N60P30К30; 3-average dose N90P60К60; 4-high dose N120- 160P90К60. Seeding rate is 5 million germinating seeds per hectare. The objects of the research were seven winter soft wheat cultivars of Krasnodar Agricultural Research Institute selection.

INFLUENCE OF TILLAGE AND CHEMICAL WAY TO CONTROL WEEDS ON WINTER WHEAT PRODUCTIVITY UNDER THE CONDITIONS OF THE PLAIN-EROSIVE AGROLANDSCAPE

abstract 1341710002 issue 134 pp. 14 – 26 29.12.2017 ru 73
This article discusses the results of the study to determine the impact of different primary tillage and herbicide against weeds in winter wheat agrocenosis. The task of the research was to determine the impact of primary tillage (moldboard plowing and surface treatment) factor A and herbicide (Lancelot) factor B on the agro-physical and agrochemical soil properties. It has been established that the content of productive moisture during the growing period of winter wheat in 0-100 cm of soil layer didn’t depend on the method of tillage. Introduction of herbicide Lancelot boosted the moisture reserves in soil compared to the control type, in the herbicide-free type the weeds absorb the large amounts of moisture. Surface soil treatment did not have negative effects on soil agro-physical properties and its structure in comparison with moldboard plowing. Number of agronomically valuable aggregates on moldboard plowing is 85.2 - 87.5%, on surface one is - 86.2 87.5%. Density of composition and waterproof aggregates under surface treatment didn’t defer to tillage. Accumulation of wet and dry mass by weeds regardless to the way of soil tillage declined to a minimum when introducing the herbicide Lancelot. The high yield of winter wheat was obtained on this type. Mathematical processing results have shown that due to factor A (main soil tillage) to moldboard plowing the average productivity is 57.5 kg/ha, on surface one is 56.0 kg/ha, i.e. the difference between treatments is 1.5 t/ha (with NSR05 on factor - 2.9 t/ha) is insignificant. To factor B (herbicides) on control the productivity is 54.5 kg/ha, introduction of Lancelot increased the productivity to 59.5 t/ha, i.e. the increase was 5.5 kg/ha at NSR05-by the factor B-2.9 t/ha, i.e. is significant. Thus, the present soil treatments had no effect on yield of winter wheat in ordinary black soil. The use of herbicide Lancelot has produced the harvest increase in 0.5 t/ha on average for 2 years

LONG TERM 32-YEAR-OLD APPLICATION OF FERTILIZERS FOR THE FERTILITY OF THE ORDINARY BLACK SOIL AND PRODUCTIVITY OF SUGAR BEET

abstract 1171603088 issue 117 pp. 1341 – 1356 31.03.2016 ru 113
The article deals with the effectiveness of mineral and organic fertilizers in long-term application (for more than thirty years) according to the influence on the fertility of ordinary black soil of the Western Ciscaucasia and productivity of sugar beet. The investigations were carried out in the long-term stationary experiment laid on the experimental stationary section "Severokubanskaya agricultural experimental station" of P.P. Lukyanenko Krasnodar Agricultural Research Institute. The experiment was laid simultaneously in time and space in two ten-course crop rotations and combined grain-grass tilled. In the structure of sown areas sugar beet occupied 10% of crop rotation area and was placed after the winter wheat. During three rotations it was studied: 1- control without fertilizer with natural forming level of mineral nutrition; 2- minimal dose N21P26K16 3- medium dose N43P52K33 ; 4 - N43P52K33, 5- high dose N96P104K68; 6- organo-mineral system¹ N43P52K34 + 12 t/ha of manure; 7- organo-mineral system² N20P24K34 + II-III rotations tillage of straw crop + 6 t/ha of manure; 8- medium dose P52K33; 9- medium dose N43K33; 10- medium dose N43K52. The soil which is used by organo-mineral system with increased and high standards of mineral fertilizers had higher concentration of mineral nitrogen. Long systematic application of fertilizer had more noticeable effect on soil phosphorus regime. The provision of soil by exchange potassium tended to decline from rotation to rotation. If at the completion of the first rotation the content of this battery was at the level 362,0-433,0 mg / kg of soil, in 2010, these values were 356,0-405,0 mg / kg of soil, remaining at the level of increased and high provision characterized to ordinary black-soil. Fertilizers for crop rotation provided almost equal yield increase: in the first rotation - 4,9-16,0 t / ha in the second 5,3- 17,1, the third 6,1-15,5 t / ha. In the moderate favorable for moisture and temperature conditions during the first and third rotation (hydrothermal index 0,8- 0,76), the value of sugar beet yield was 30,1-46,1 and 35,7-52,1 t / ha, in comparison with tougher conditions for the second rotation (hydrothermal index 0,41- 1,96) higher up to 2,6-6,5 9,2-16,0 t / ha. Research carried out in long-term stationary experiment showed that long-term use of fertilizers prevents to the loss of soil organic substances, supporting the humus content at the level of 3.95-3.99%, and organicsystems contribute to its reproduction to 4,01-4,21%. soil nitrogen state is stabilized. However, there is a tendency of decrease of the exchange potassium in mineral fertilizer systems. In the conditions of insufficient moisture supply of the northern zone of Krasnodar region the most applicable norm is N60P90R60, both in mineral and organic-systems, ensuring the collection of root crops within 43,0-45,2 t / ha, with an estimated amount of sugar 6,92-7, 14 t / ha. The given systems of fertilizer provide the yield of root crops 53,3-56,0 t / ha with the synthesis of sugar 8,19-8,70 t / ha. Increasing the rate of fertilizer in 2 times from medium to N120P160R120 doesn’t increase the productivity, reduce sugar content of root crop to 0.4-0.8%. It is undesirable to use fertilizer that are unbalanced in nutrition elements in which root crops yield declines from 5.4 to 19.0%, and current biological sugar from 6,1 to 25,9%

THE INFLUENCE OF LONG-TERM APPLICATION OF FERTILIZERS ON THE SUGARINESS OF BEET IN THE CONDITIONS OF INSUFFICIENT WATERING OF THE WESTERN CISCAUCASIA

abstract 1171603083 issue 117 pp. 1288 – 1302 31.03.2016 ru 143
This article presents the experimental material obtained from long-term stationary experiment of GNU "Severokubanskaya agricultural experimental station" in P.P. Lukyanenko Krasnodar Agricultural Research Institute. Stationary experience was founded in 1978. It had two ten-course crop rotations and combined graingrass tilled. The ordinary black soil, low-humic, heavy loamy in mechanical composition. The capacity of humus horizon is 113-116 cm with a total content of humus on the date of the experience beginning is 3.88%. Arable (0-30cm) layer was characterized by the following parameters: total nitrogen content - 0.22-0.24, mineral -10,0-10,5mg / kg of soil, total phosphorus-0,16- 0,19%, labile phosphorus - 12,2-12,9mg / kg soil total potassium -1,7-2,0%, exchange potassium- 386mg / kg soil. The degree of saturation of bases is 80-90%. The amount of absorbed bases is 30-40 m ekvg/ 100 g of soil. The reaction of the soil solution is weakly alkaline (PH water 8.0-8.2). The predecessor is winter wheat. General Agrotechnics is recommended for a given soil and climate of region. Solid mineral fertilizer were applied as mineral fertilizers in combination with organic fertilizer in the form of half-decomposed cattle manure. According to agro-climatic zonation the northern zone of the Krasnodar region, where the research was conducted, is related to the zone of insufficient watering with hydrothermal coefficient 0.7-0.9 with an annual rainfall of 350.5 to 899.8 mm. During the autumn and winter period, which determines the accumulation of water in the soil, from 150.3 to 426.8 mm of rain falls or 30,4-68,9% of the annual amount. During the vegetation of sugar beet from germination to harvest -112,0- 588,9mm of rain falls, with an average daily temperature of the air 16,5-20,000С, including the period of the greatest growth of roots and accumulation of sugar from 3.2 to 557.1 of rain falls with air temperature 19,5-28,800С. Hydrothermal index is 0,01-2,83. During the years of the research 19% of years have been characterized as unfavorable (hydrothermal index 0.67), 44% of years as moderate on moisture supply and temperature conditions (hydrothermal index 0.99) and 37% of years as favorable (hydrothermal index 1.05). The generalization of the research results obtained by us in the long-term stationary experiment, allowed us to estimate the impact of different standards and systems of fertilizer on the productivity of sugar beet and sugar content in the roots. On average, during the years of research, the root harvest under the influence of fertilizer amounted to 36,7-45,6 t / ha per unit area with the addition to the control variant, that isn’t manurable, amounted from 6.6 to 15.5 t / ha. The highest yield of root is 43,0-45,6 t / ha which was obtained with systems of fertilizer with complete mineral nutrition
