The search for new mechanisms of crop growing modernization was initiated by post-Soviet change of the socio-economic formation, rejection of the virgin-land holistic principle of organizing agriculture with its wheat invariant, as well as transition from the extensive zonal system to adaptive landscape and precision agriculture. Above all, this refers to agricultural landscapes of the forest steppe zone of North Kazakhstan, which is the oldest region of the country’s dryland farming. The article deals with a relevant direction of agrolandscape research – geoinformation agrolandscape mapping with the use of aerial photography materials from unmanned aerial vehicles (UAV). The aim of the work is to prepare optimal cartographic support for effective agricultural production in light of agricultural intensification in the region and depletion of natural fertility resources. Modern methods of geoinformation agrolandscape mapping have been used, their effectiveness is shown through the example of key areas. The features of the landscape structure of outlier forest steppe agrolandscapes have been identified with the help of utilitarian agroecological typology of land; the types of basic geoinformation cartographic materials to be used in precision agriculture have been defined. We consider it possible for the agrolandscape mapping experience to be extended to other farms of the region, which would ensure productive agricultural management.

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.

The Creation

Soil protection in agrolandscapes is especially necessary in conditions of intensification of production and increasing anthropogenic pressure on them. This complex should fit into the landscape farming system. The more intensive the load on the land in the farm, the higher the level of soil protection against destruction. The article notes that raising soil fertility, increasing crop yields and ecological environmental improvement are possible only on the basis of agrolandscape farming system, which allows to establish the correct ratio of arable land, meadows and forests. The transition to such a system of agriculture requires: development of a project for agrolandscape land management with a set of anti-erosion measures for each farm; adjusting the structure of sown areas taking into account market conditions, that is, increasing the area of productive crops in demand (winter and spring wheat, perennial grasses), which in combination with occupied and green manure pairs determine the structure of biologized crop rotation; widespread use of legumes (peas, vetch) as factors in the biologization of agriculture. The efficiency of expanding the area of perennial grasses to 25 % of arable land in some areas of the Non-Chernozem region and the Belgorod region is shown. Here, techniques that increase the efficiency of arable land are based on strict adherence to crop rotation with legumes, the use of adaptive varieties, and the use of biologized fertilizer and plant protection systems. It is noted that the creation of a system of shelterbelts makes it possible to reduce the cost of planting and growing them in comparison with single forest belts and what is very important for farmers is to sharply increase the return on their exploitation in the form of increased increases in crop yields. The creation of forest-sized landscapes will improve the environmental conditions for the cultivation of crops.

Alternative Organizations

The Participatory Plant Breeding (PPB) concept emerged twenty years ago, particularly with the aim to build alternative organizations of the plant breeding activities in developing countries. It now as well questions the developed countries, in the frame of a more global expectation to make all the stakeholders more involved in the agricultural production, from the farmers to its final clients. We discuss here some of the questions addressed by this trend with regard to the definition of the ideotype: (a) different forms of PPB? (b) changing the paradigm: Client Oriented Breeding? (c) a new way to manage {genotype * environment} interactions? (d) mainly societal concerns at stake? (e) biodiversity and ideotypes. As the same key, technical, limiting factors are involved in both PPB and classical breeding, it is suggested to consider PPB as one of the ways in the frame of a general expectation for diversification, thus eventually resulting in the promotion of alternative ideotypes, rather than an alternative process.

Ridge Tillage

Approaches to crop production that successfully reduce weed seed production can benefit farming systems by reducing management inputs and costs. A 5-yr rotation study was conducted in order to determine the effects that interactions between crop rotation, tillage, and amount of herbicide and fertilizer (management inputs) have on annual grass and broad-leaved weed seed production and fecundity. There were 10 crop rotation and tillage system combinations and three levels of management inputs (high, medium, and low). Green and yellow foxtail were the major weed species, and together they yielded between 76 and 93% of collected weed seeds. From 1990 to 1994, average grass weed seed productions were 7.3 by 103, 3.7 by 1036.1 by 103and 5.7 by 103seeds m−-2, whereas average broad-leaved weed seed productions were 0.4 by 103, 0.4 by 103, 1.4 by 103, and 0.4 by 103seeds m−-2in crop rotations using conventional tillage (moldboard plow), conservation tillage, no tillage, and ridge tillage, respectively. Crop rotations using conventional or ridge tillage consistently produced more grass and broad-leaved weed seeds, especially in low-input plots. There was little difference in weed seed production among input levels for crop rotations using conservation tillage. Comparing rotations that began and ended with a corn crop revealed that by increasing crop diversity within a rotation while simultaneously reducing the amount of tillage, significantly fewer grass and broad-leaved weed seeds were produced. Among the rotations, grass and broad-leaved weed fecundity were highly variable, but fecundity declined from 1990 to 1994 within each rotation, with a concomitant increase in grass and broad-leaved weed density over the same period. Crop rotation in combination with reduced tillage is an effective way of limiting grass and broad-leaved weed seed production, regardless of the level of management input applied.

The Creation

The article reflects the issues of the current state of scientific research at the FSBSI FSVC, shows the directions and prospects for the development of selection and seed production of vegetable crops. The main mission of the selection and seed-growing work of the FSVC is the creation and reproduction of varieties and hybrids of vegetable and melon crops of a new generation, characterized by resistance to abiotic and biotic stressors, high productivity and product quality. One of the main ways to increase the efficiency of the breeding process is the use of modern methods of biotechnology and molecular genetics, which make it possible to obtain new genotypes and reduce the time of breeding. Success has been achieved in the creation of homozygous lines of cabbage, squash, cucumber, carrots. For the first time, it was possible to complete a full cycle of obtaining doubled radish haploids in microspore culture in vitro. The institution pays special attention to immunological research on the resistance of crops and new varieties to diseases, as well as protecting plants from pests and diseases. Phytosanitary monitoring, assessment and selection of resistant genotypes are carried every years. One of the important theoretical and practical problems solved at the institution is the development of environmentally friendly products based on preparations obtained from plants with a high content of biologically active compounds with adaptogenic properties. In the center, a new direction of research in traditional breeding has received significant development - the creation of varieties of vegetable plants with an increased content of biologically active substances and antioxidants, on the basis of which functional products are created. The persistence of modern varieties and hybrids of table carrots, depending on the biochemical composition, has been studied. Methods for enriching vegetable plants with micronutrients are being developed. A large amount of scientific research is being carried out on the development of technologies for the cultivation of new varieties and hybrids, as well as technologies for their seed production. At the branches located in different soil and climatic conditions, hospitals were established to study the interaction of factors controlling soil fertility and the productivity of vegetable crops in agrocenoses (crop rotation, soil treatment systems, fertilizers and plant protection). In general, at the FSBSI FSVC, all research is aimed at developing and improving methods in breeding and seed production of vegetable crops, creating new breeding achievements and developing varietal technologies for their cultivation.

Concerning the red clover breeding, it is essential to choose as genitors those varieties that possess good characteristics. In order to identify potential genitors, two red clover varieties were studied at Cluj-Napoca: Roxana, diploid variety and Napoca-tetra, tetraploid variety. The analyzed traits comprised the number of capitula/plant, number of seeds/capitulum and the binding process, under the aspect of their contribution to the seed crop and the interaction between those components, in order to provide important clues about di-and tetraploid red clover seed production, for plant breeding. The highest variability (s%=30) presented regarding the number of flowers/capitulum, diploid variety comparatively with a lower variability (s%=26) regarding the number of flowers number/capitulum, tetraploid varieties. Several traits were compared between di-and tetraploid red clover varieties in order to find genitors which can be used for creating new genotypes with high seed production level.

Production Demand

Our country has provided about 52% of vegetables from domestic production, the rest part imported others from outside. Thus, imports of potatoes and vegetables have been reduced last year, for this reason, main vegetable seeds, were produced domestically and provided over 80 percent of the country’s demand. In the future domestic production demand of vegetable goal set working to provide by 100 percent from government our country in this connection issues urgent need to solve sowing seeds, variety supply, seed production, and plant protection. According to our research, during the growing season, 150-350 weeds growing per 1m2 of rounded onions shows that the amount of crop damage is relatively high. For the purpose of control against weeds in the onion field with 3 repetitions of 7 variants of 2 types of herbicides are conducted experimental research. These include; pre-emergent Estamp (Stomp) herbicide applied in doses 2.5; 3.5 l/ha that controls all types of weeds, but showed results of 65.2-72.4%. The growing season during a selective post-emergent of Gaur herbicide in doses 0.7; 0.9l/ ha used against broadleaf and grassy weeds that became clear of weed species density reduced by 92.7-93.4%. It was tested in this study Pendimethalin, 33% + Oxyfluorfen 24 % mixture herbicides have reduced the number of weeds by 92.4-94.1%.
