INTERCROPPING MAIZE - COMMON BEAN ENHANCES MICROBIAL CARBON AND NITROGEN IN LOW-PHOSPHORUS SOIL UNDER MEDITERRANEAN CONDITIONS
Latati M., Aouiche A.R., Nazih Y.R.
Abstract
The positive effect of intercropping under low phosphorus (P) conditions has already been reported in previous works. The aim of this study was to test the hypothesis that intercropping (common bean - maize) in P deficient soil, can enrich carbon (C) and nitrogen (N) of the microbial biomass (MB) through a transfer from root nodules of the plant and rhizospheric microbial flora in a field located in “Setif region” in northern Algerian agroecosystem(Mediterranean climate). The rate of nodular N sequestered in intercropped common bean was higher compared to sole crops and fallow. However, under intercropped and low P conditions, the rate of nodular N sequestered is highest over two years. Carbon of the microbial biomass (MB-C) is higher in the intercropping compared to sole crops and fallow but it is even higher in P deficient soil. Moreover, a strong correlation is established between nodular C and MB in intercropping under low P conditions. In these same conditions, the total soil respiration was the highest and the lowest C:N ratio of MB was recorded. These results showed that in low P soil, intercropping is a good solution to enhance the rhizospheric MB that can fertilize the soil and recycle mineral elements.

WATER-SAVING IRRIGATION REGIMES FOR VEGETABLE CROP PRODUCTION UNDER CONDITIONS OF VOLGA-DON INTERFLUVE
Akhmedov A.o., Dzhamaletdinova E.E., Zasimov A.E.
Abstract

Irrigation regimes and rates of mineral fertilizers for obtaining the expected yields of vegetable crops under conditions of light chestnut soils of the Volga-Don interfluve are considered in the study. We established that irrigation regimes and norms of mineral fertilizers proposed in our field study for table beet (Beta vulgaris) and carrot ( Daucus carota) cultivation allow yielding in the range of 60...80 t/ha. Thus, for example, the maximum yield of table beet 84.1 t/ha was obtained in the variant with 80% pre-irrigation soil moisture and N230P180K100 fertilizer at a variable depth of soil moistening (0.3...0.5 m). Changes in fertilizer dose from N130P80K20 to N230P180K100 contributed to 63.7...84.1 t/ha yield increase, which is 10-20% higher compared to other variants. Change in soil moisture from 70-80-70 to 80-80-80% of FMC in combination with fertilizer dose from N150P70K180 to N210P100K260 increased carrot yields from an average of 57.9 to 81.6 t/ha. The highest yields (81.6 t/ha) were obtained when maintaining pre-irrigation soil moisture of 80-80-80% of FMC and applying N210P100K260 fertilizer rate. In general, beet and carrot cultivation on light chestnut soils using drip irrigation is the most efficient. To maintain water regimes of the soil adopted by the experiment, a different irrigation frequency was required. When increasing humidity level from 70 to 90% FMC frequency of irrigation increases, and irrigation rate decreases. The total consumption of moisture in the experiments increased with an increase in moisture content - from 4,417 m3/ha in the variant with 70% of FMC to 5105 m3/ha in the variant with 90% of FMC. The largest total water consumption of table beet was noted in the variant with a differentiated depth of soil wetting and averaged 4,530-5,105 m3/ha. The share of irrigation water in the total water consumption of plants increased from 73.3 to 75.7%. Application of mineral fertilizers reduces water consumption of table beet. The smallest coefficient was obtained in the second irrigation regime variant, when humidity was maintained at 80% of FMC with different wetting depth. This situation was observed in all variants of irrigation regimes and fertilizer applications. This confirms that differentiating wetting depth according to table beet growth stage makes it possible to use irrigation water more economically at all rates mineral fertilizer application.

EFFICIENCY ESTIMATION OF STRIPTILL SOIL PROCESSING TECNOLOGY
Borisenko I.B., Chamurliev O.G., Chamurliev G.O., Meznikova M.V.
Abstract
This study explores the technology of chilling from the point of view of anthropogenic impact on soil. The influence of the arrangement of workers on technological rocessing is analyzed. The efficiency of resource-saving deep cultivation technology in production of row crops on example of sunflower growing in Volgograd region is estimated. We give technical and economic assessment of sunflower cultivation depending on the technological process of chilling. We defined a competitive technology of basic soil cultivation. Analysis of data obtained shows that the largest area of cross-section of the formation is produced when soil is treated with chisel tools as working organs are arranged such that they form a zone of continuous loosening, accordingly, it has the greatest anthropogenic impact. Field experiments also showed that deep loosening belts to a depth of 0.25...0.35 m, alternating with strips without treatment, are characterized by positive processes. Unprocessed areas become overcrowded (more than 1.3 g/cm3), so they create less favorable, in comparison with processed, conditions for the development of some species of perennial weeds. Studies have shown that, with the main soil-free tillage of the soil to a depth of 0.3 m, from the stubble of winter wheat, stubble conservation was consistent: 69.67% - over the treated band using striptill technology; 76.33% - on the processed strip by a chisel with a trail of 0.7 m; 68.67% for a chisel with a trail of 0.35 m. After the passage of the aggregates on the soil surface, all stubble remains within the requirements for SRT AIST 4.6-2010 (more than 60%). The use of striptill technology reduces fuel costs by 35.5% relative to the classical chiesel, and by 27.3% relative to the minimum technology. Accordingly, the cost of wages is reduced by 37.5% compared to the classical chisel and by 24.8% compared to the minimum chisel technology.

RICE CULTIVATION IN AMUR REGION
Borovoy E.P., Makannikova M.V., Lapshakova L.A.
Abstract
Rice plays an important role in the modern diet of Russian people. It occupies a leading position in area, yield, and gross grain harvest among all cereal crops. The aim of the research is development of optimal irrigation regimes that ensure rational use of water resources in southern agricultural zone of Amur Region. Setting and conducting field and laboratory experiments, system approaches and modern research methods were used. The article presents the results of studies on rice cultivation under different irrigation regimes. In the southern zone of Amur Region, along with water regimes of 70, 80, 90% of FMC, differentiated rice irrigation regimes were studied, combining differentiation of presumed humidity thresholds and wetting depth of active soil layer 75...85% of FMC (0.4 and 0.6 m); 80% of FMC (0.4 and 0.6 m). In addition, various flooding regimes of rice field (short and intermittent flooding), seeding rates, timing of sowing, rice cultivars were studied. Obtaining a rice grain yield of more than 4 tons per hectare is ensured by application of mineral fertilizers in the dose of N120P30K30 and seeding rate of 5 million seeds. Optimum seeding time was set from 20 to 25 May. Based on the results of the research, irrigation water was saved, as well as yield increased by optimizing irrigation rice regimes using sprinkling by differentiating presumed moisture thresholds and wetting depth. When rice was cultivated under flooding system of irrigation, it was established that regime of shortened flooding turned to be optimal. When sprinkling in conditions of southern agricultural zone of Amur Region, differential irrigation regime of 75...85% of FMC in active soil layer was 0.4 and 0.6 m.

CROP ROTATIONS ENSURING THE GREATEST YIELDS UNDER DRY CONDITIONS OF THE LOWER VOLGA REGION WATER-SAVING IRRIGATION REGIMES FOR VEGETABLE CROP PRODUCTION UNDER CONDITIONS OF VOLGA-DON INTERFLUVE
Zelenev A.V., Pleskachev Y.N., Seminchenko E.V.
Abstract
An estimation of various agro-biological methods in crop rotation of dry-steppe zone of light chestnut soils of the Lower Volga region is given. The effectiveness of a grain-fallow four-field crop rotation has been established, where green manure crop mass of winter rye, straw and leaf-weed mass of crops are plowed in soil, which increases organic matter and nutrient content in soil, reduces humus loss, and stabilizes grain yields. It was noted that only in four-field grain-fallow green manure crop rotation there is a positive balance of the main nutrients in the soil per hectare, where additional organic matter enters arable layer of soil in the form of winter rye green manure crop. In this variant, the balance was: nitrogen +39.7; phosphorus +0.7 and potassium +49.9 kg/ha. In six-field grain crop rotation with ginger as a sidereal crop, a positive balance is achieved only for phosphorus +14.1 and potassium +35.5 kg/ha, for phosphorus there is a negative balance of -3.5 kg/ha. In the eight-field grain crop rotation with 50% of legume crops, a positive balance is achieved only for potassium, +29.8 kg/ha. The balance of humus can be regulated by the structure of areas, alternation of crops in field crop rotations, application of plant residues in the form of sidereal crops, straw, leaf-weed mass, decrease in the proportion of fallow and tilled crops in the structure of biotivated crop rotations. The most complete biologization is possible in green manure crops, where humus losses decrease 1.5 times or more. A positive balance of organic matter is ensured in four-field biologized grain-fallow crop rotation - +3.33 t/ha.

OPTIMIZATION OF INNOVATIVE STRIP-TILL TECHNOLOGY OF MAIZE CULTIVATION FOR GRAIN ON BLACK SOILS IN STEPPE ZONE OF VOLGOGRAD REGION
Ivanov V.M., Kubareva A.V.
Abstract
Studies carried out in steppe zone of chernozem soils of Volgograd region have established that winter wheat after fallow and maize are the best precursors for maize, cultivated for grain under strip-till technology. Growing maize after sunflower annually led to a significant decrease in crop yields. N66P32K32 turned to be the best rate of mineral fertilizers. Seeding rate of 60 thousand seeds per ha was optimal for early maize hybrids. It was found that total water consumption over the three-year period was 2653 m³/ha with fertilizer rate N66P32K32, and corn and sunflower rose to 2,700 and 2,695 m³/ha. At N66P32K32, winter wheat plants used moisture most economically. The water consumption coefficient, which shows moisture consumption for creation of a ton of produce, was 421.0 m3/t. For corn, it increased by 34.1, and for sunflower by 247.7 m³/t. In control after all precursors, moisture consumption per ton of grain sharply increased: according to winter wheat, water consumption coefficient was equal to 551.9 m³/t, corn and sunflower were 53.0 and 360.1 m³/t more. The maximum values of dry matter accumulation in 2013 and 2015 were recorded at flowering stage: depending on precursor, after winter wheat - 9.07 and 7.24 t/ha, after maize - 8.67 and 6.77, and after sunflower - 6.64 and 4.76 t/ha, respectively. Over the research years the largest daily increasing of dry biomass during germination-flowering was observed after winter wheat - 452 and 361 kg/ha, decreased slightly after corn - 432 and 337 kg/ha, and a significant decrease was noted after sunflower - 331 and 237 kg/ha. In arid 2014 season, during the period of precipitation deficit, the indicators were significantly lower. The best yield results were obtained in more favorable 2013 and 2015 research years. The studies showed that the best maize precursor was winter wheat - 5.524 t/ha. The lowest yield was obtained after sunflower - 3,456 t/ha. Moreover, maximum yield was achieved at fertilizer application N66P32K32 - 5.324 t/ha, N50P16K16 - 4.813 t/ha and in the control - 4.015 t/ha.

LOCAL IRRIGATION METHODS FOR VEGETABLE PRODUCTION IN SOUTH OF RUSSIA
Ovchinnikov A.S., Hodyakov E.A., Milovanov S.G.
Abstract
In the Southern Federal District, where the Volgograd region occupies a significant territory, cultivation of vegetable crops is impossible without irrigation. There was a large number of wide-spread sprinklers in the USSR. Each unit of this system watered at least 60 to70 hectares, required a lot of water pressure that resulted in high operating costs. Therefore, currently, such local irrigation methods as drip and subsoil irrigation have a broad development perspective. Both irrigation methods favorably differ from sprinkling by a significant increase in yield of vegetable crops, irrigation water saving, ease of operation and rapid investment return. In this regard, the main goal of our research, conducted at Volgograd State Agricultural University, is development of techniques and technologies for drip and subsoil irrigation that allow receiving projected vegetable yields while maintaining soil fertility and environmental safety. The research have shown that it is possible to obtain planned yields of 60, 70 and 80 t/ha of zucchini and table beet using drip irrigation in steppe zone of southern Russia on light chestnut soils. Therefore, it is necessary to observe irrigation regimes with maintaining pre-irrigation moisture (PIM) 75-85-75 and 85% of field moisture capacity (FMC) simultaneously with application of calculated doses of mineral fertilizers. Moreover, it is important to apply increased doses of mineral fertilizers with decrease in intensity of irrigation regime due to reduction in soil moisture content to 75% of FMC. The planned radish yield of 80 tons per hectare with subsoil irrigation can be obtained in variants with differentiated soil moisture 75-85-75% of FMC and 1.4 m distance n t between humidifiers, and also maintaining constant soil moisture at 85% of FMC at plots with 1.2 and 1.4 m distances.

WATER-SAVING IRRIGATION REGIMES FOR VEGETABLE CROP PRODUCTION UNDER CONDITIONS OF VOLGA-DON INTERFLUVE
Nagornyy V.D., Kamssou K., Lyashko M.U.
Abstract
Soils of the southern region of Chad are developed on wind-drawn sand and colluvio-alluvium deposits of two main rivers Logone and Chari. This region of Chad is principal agricultural zone of Chad. Evaluation of physical and chemical properties of sandy soils and their fertility in this region revealed that some soils have very high content of strontium. With aim to locate areas with high content of srontium in soil, and to study its dependence on physical properties of soil and translocation of strontium in soil profile nine pedons were dug on different fields intensively used for agricultural production. Using X-ray spectrometric analysis and radiometric measuring of soil samples it has been revealed that Sr content in soil samples varies from 10 to 270 mg/kg of soil depending on type of soil, depth of soil layers, clay and organic content. Strontium content negatively correlates with total content of calcium and phosphorus in layers of soil. Low CEC of soil may be a reason of translocation of strontium from higher to lower layers of soils. Strontium content in soils do not relates with level of radioactivity of soils under study. The highest content of strontium has been found in soils developed on colluvio-alluviumdeposits. Very wide Ca/St ratioin soil samples of alluvial hydromorphic soils may cause increase of Sr content in vegetable food and drinking water. This may be one of etiological factors which directly or indirectly may cause misbalance in mineral nutrition and severe diseases of a man. It worth of considering necessity of further studies of Sr dynamic in soils under different crop production systems and how to mitigate negative effect of natural pollution of soils with this element.
