OPTIMIZATION OF STRUCTURE OF SOWING AREAS AT APPLICATION OF METHODS OF MATHEMATICAL DESIGN FOR TERMS OF FOREST-STEPPE OF WESTERN SIBERIA

abstract 1331709022 issue 133 pp. 263 – 274 30.11.2017 ru 217
Alternation of crops, will remain a fundamental element of zonal technologies of their cultivation for a long time. Application of methods of mathematical model operation will allow to come to new level in the solution of the questions of effective use of an arable land, through application of models optimizing it. Results of researches which basis data of long-term observations are will be especially valuable. They used data of the long-lived stationary experiments on studying of alternation of crops in crop rotations of last more than five rotation. Stationary experiences are located in a forest-steppe zone of Western Siberia on the fields FGBNU "SIBNIISKH". The purpose of researches consisted in optimization of use of an arable land at application of methods of mathematical model operation for preservation of soil fertility. The model allowing when performing particular conditions is given in work (balance of a humus, work expense, a metabolic cost, etc.) to optimize use of an arable land against the background of preservation of soil fertility of the soil, receiving production, economic and power efficiency. It is shown that at alternation of grain crops with clear steam, formation of a harvest happens due to natural fertility of the soil what the negative balance of a humus which reaches 0,18 – 0,78 tons from hectare testifies to. At alternation of field cultures without clear steam the harvest was formed against the background of reproduction of organic matter of the soil, due to increase in vegetable oddments from use of fertilizers, the balance of a humus was positive – 0,15 – 0,28 tons from hectare. Use along with clear steam, busy steam, colza on green fertilizer, and also straw as organic fertilizer for grain crops, 2,01 tons from hectare of commodity grain were received, at a share of clear steam – 16,8%, busy steam – 11%, summer grain – 72,2% of arable land. Increasing in crop rotations of West Siberian Square with use as organic fertilizer of straw, busy vapors and green fertilizers, it is possible to achieve reproduction of fertility of the soil with some decrease in an exit of commodity grain to 2 tons from hectare

PRODUCTIVITY OF SPRING WHEAT DEPENDING ON USE OF FUNDS OF INTENSIFICATION AND PREDECESSORS IN SOUTHERN FOREST-STEPPE OF THE WEST SIBERIA

abstract 0971403045 issue 97 pp. 624 – 632 31.03.2014 ru 1108
The article presents the results of studies on the influence of predecessors and funds of intensification on the yield of spring wheat in the field crop rotations. Studies carried out in the long stationary experiment in crop rotations over the past seven rotations. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia

THE EFFICIENCY OF CULTIVATION OF OILSEED CROPS (CANOLA, SOY) IN A FIELD ROTATION FOREST-STEPPE ZONE OF WESTERN SIBERIA

abstract 1001406042 issue 100 pp. 689 – 698 30.06.2014 ru 1087
In the long-term stationary experiment since 1968, we have studied the influence of crop rotation on soil fertility and productivity. The modernization schemes of field rotations in the direction of alternation crop change were held 40 years later, by introducing a scheme of oilseeds (canola, soy). According to the research, the authors made conclusions about the efficiency of cultivation of oil crops in crop rotations in the region. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia
