In the sand cultivation requires a special system of farming with a complex of measures for plant protection from deflation (strip sowing, nonmoldboard tillage system with crop residues, soil protecting crop rotation, coulisses with tall-stalked plants and the system of the forest shelter belt), application of the fertilizers, ameliorants (clays), selection of crops and varieties, which ensuring high yields in relatively poor soils, rational use of agricultural machines and implements, combining the performance of several field operations in a single pass technique, laying -out of the individual plots for tractor driving located on the internal land masses. In the article, in the framework of the state order for the development of adaptive-landscape farming systems for the dry steppe zone of the Chechen Republic, the results of studies on agro-ecological assessment of climatic conditions of the administrative areas of semi-desert and dry steppe zones of the region, including the problem of desertification. In this regard, the above-mentioned factors contributing to the loss of fertile layer of soil, disruption of their structural properties, mechanical composition. On the basis of these results, the authors propose a complex of agrotechnical and reclamation measures for prevention of desertification in sandy soils of semi-desert and dry steppe zones of the Chechen Republic. The most of sandy soil lands are not protected by forest belts and therefore crop cultivation is carried out by strip cropping. Strips width in dry steppe should be 98.43…164.04 ft and semidesert zone 49.21…98.43 ft. The strips are located vertical to prevailing winds which cause the soil erosion. On the semidesert zone should be six-fields crop rotation: 1,2,3,4 – perennial grass, 5 – melons and grounds, 6 – winter rye and sainfoin for hay.

Fertility reproduction features of southern carbonate chernozems in the conditions of the dry-steppe zone of Northern Kazakhstan (Shortandinsky district of Akmola region) are studied. We studied the changes of humus content in the model micro plot experience. Various variants of the experiment with non-fallow and dump steam without fertilizers, grain crops with different doses of mineral fertilizers, manure, as well as with straw and sideral crops (pea-oat mixture, Donnik) are laid down. The introduction of rotted manure in small doses of 20 t / ha did not provide an increase in humus during crop rotation. When adding 40 and 80 t / ha of manure to the fallow field, it allowed to increase the humus content by 0.24 and 0.18 % of the initial amount. The introduction of sideral steam and perennial grasses into crop rotation enhanced the processes of humification and provided a positive balance of humus. In this version of the experiment, the amount of humus increased by 0.10-0.13 %. The greatest accumulation of organic matter occurred when using melilot: the increase in humus was 0.39 %. Long-term cultivation of permanent wheat crop in one field, even with high doses of mineral fertilizers, does not provide significant reproduction of soil fertility. The application of mineral fertilizers does not contribute to the increase of humus in the soil. The greatest decrease in humus content in southern chernozems is observed in the permanent dump and waste-free pair-0.11 and 0.13% over a 6-year period of observations.

Abstract. The work was carried out to modify the method of assessing the viability of plants, taking into account the limiting factors of the climatic conditions of the Orenburg Preduralie. Are studied several species of plants, during the introduction at the steppe zone (on example of Оrenburg). Introduction study of all taxons was carried out for 8 years (20122020). The results of visual and laboratory observations of the seasonal development of species. During the entire observation period such indicators, as lignification of shoots, heat resistance, drought resistance, winter hardiness, shoot-forming capacity, height increase, generative development, and possible ways of reproduction in culture were evaluated annually. For each indicator numerical values in points corresponding to a certain state of the plant were selected. Based on the integrated assessment, the total viability score was calculated separately for each year of observations and the average score for the observation period. The sum of the average scores is an integral numerical expression of the viability of the introduced plants. Was established that the studied species belong to the I and II group relatively the criterion of life skills. The most species and sorts are among the most promising plants for introduction.

Effect On Yield

In recent years, sustainable agriculture has revitalized interest in crop rotations and their effects on crop performance and agroecosystem biodiversity, including weeds. This article used winter rye as an example and focused on the crop rotation (CR) impact on species, taxonomic and functional diversity of weed communities and analysed the contribution of crop rotation to protecting yield and regulating weed abundance. Long-term continuous rye cropping (CC) provided a background for comparison. Two variants of plant protection were also adopted: herbicide application (H+) and no plant protection (H−). The data from the 10th, 30th and 50th years of the experiment were included in the analysis. Diversified crop rotation with no chemical protection resulted in a satisfactory rye yield and reduced weed abundance—especially problem species—without a decrease in weed species diversity or functional diversity. When rye was grown under crop rotation, the herbicide application had no effect on yield protection, but it was harmful to weed biodiversity. The rye yield correlated negatively with weed biomass, but did not show a link with weed biodiversity. Continuation of long-term experiments as a research basis for contemporary and future scientific challenges is necessary.

Complex field experiments were carried out in Agricultural research institute in 1969. The field trials included five different crop rotation systems. In each 6-field rotation system the specific percentage of cereals (%) varied from 50 to 100%, perennial grass (clover+ timothy) - 16.7 to 33.3%. The highest winter rye yields were obtained from crop rotation systems with cereal proportion up to 66%. Including buckwheat in the crop rotation winter rye cultivation is highly productive in crop rotation systems with cereal proportion even up to 83%. Yield of winter rye in long-term monocultural sowings decreases even up to 0.74h-1. Winter ryetreatment with herbicide Grodil increases its yield up to 0.40 ha'1. Foreplants of barley according to their good influence on barley yield (descending): buckwheat, oats, winter lye. Barley yield in long-term monocultural sowings decreases for up to 1.17 t ha-1.Oats in crop rotation systems with cereal proportion up to 83% had very low yield amount alterations after different foreplants. Essential oat yield decreasement was noticed in perennial monocultural sowings. The best foreplants for spring wheat are buckwheat and lupine. The highest yield of buckwheat is get from monocultural sowings, but using potatoes as buckwheat foreplant gives essential yield decreasement. Distribution of perennial weeds, especially quickgrass, is 7,4 times more in crop rotation systems with high cereal proportion than in systems where also buckwheat and potatoes are cultivated. Treatment of herbicides and fungicides is more effective in monocultural sowings than in crop rotational systems, however increasement of crop yield after pesticide treatment is less remarkable than if we follow right crop rotation and choose optimal foreplants for each culture. Latest results from years 2002 to 2004 are shown in this article and are considered to be an addition to previous publications.

The article presents results of studies of comparative productivity and cultivation economic efficiency of soybeans, peas, lupine and chickpeas, depending on main tillage systems in crop rotation and the level of plant protection from harmful organisms. Grain legumes are capable of forming a seed yield of 2.0 t / ha in the conditions of the forest-steppe zone of the Volga region. Three-year experimental studies have shown that the studied leguminous crops can be arranged in the following row according to the yield level: peas - 2.51 t / ha> lupine - 2.12 t / ha> chickpea –2.11 t / ha> soybean - 2.10 t / ha. Evaluation of the effect of soil tillage in cultivation of grain legumes showed a significant yield increase by plowing for 25-27 cm in comparison with tillage for 12-14 cm for all the studied crops, a yield increase for adaptive-integrated plant protection was also noted in comparison with minimum protection (protection only against weeds). Studies show that lupine crops had an advantage in protein content, its yield is from 533 to 802 kg / ha, as for soybeans, protein yield was 449-666 kg / ha, peas - 430-521 kg / ha, and chickpeas - 346-486 kg / ha with the advantage of the mentioned variants. A higher conditional net income was obtained on soybeans (31555-44584 rubles / ha) and chickpeas (27777-40037 rubles / ha), especially on combined tillage in crop rotation. Plant protection systems had an equal impact on economic efficiency of their cultivation; in some variants, adaptively integrated plant protection was less effective

The structure of the cultivated areas serves as the basis for the system of crop rotation, the main link in modern farming systems. The structure of sown areas and the system of crop rotations as the fundamental links of the farming system have close direct correlations and feed-backs with all other links of the farming system. On the one hand, they are fundamental, first of all, for organizing the soil protection and nature conservation of the territory, since in each farm the sown areas of agricultural crops on arable land prevail over the area of other agricultural lands. On the other hand, the system of crop rotation, which is developed on the basis of the promising structure of sown areas, is the basis for other links of the farming system. For more efficient use of arable land, increasing the yield of major agricultural crops, meeting the needs of farms with crop production, improving soil fertility, it is necessary to change the structure of sown areas taking into account the specific agro-climatic conditions of the steppe zone. There are two subzones in the considered zone: arid and moderately arid one. We have substantiated and optimized the structure of cultivated areas in order to increase soil fertility, ecological balance and productivity of agricultural landscapes for these two sub-zones of the steppe zone. For the arid sub-zone, in the structure of sown areas, winter and spring crops should occupy 51.7%, legumes – 9.8%, fodder – 12.5%, industrial – 21%, vegetables – 5%. For the moderately arid sub-zone in the structure of sown areas, winter and spring crops should occupy 42.0%, legumes – 10.3%, corn for grain – 13.7%, fodder – 10.5%, industrial – 17.0%, vegetables – 5%, potatoes – 1.5%.
