The development of rational system of basic soil tillage results in formation of sufficiently high crop yields. A two-factor field experiment was carried out to address these issues when cultivating winter rape cultivars on light chestnut soils of the Primorsko-Caspian sub-province of the Republic of Dagestan. VEM (standard), Elvis and Meteor winter rape cultivars were studied in the experiment. The following methods of soil tillage were studied: real tillage (control), subsoil tillage. The research revealed that there was no significant difference in agrophysical indicators between the soil cultivation variants. Data on weed infestation of winter rape fields showed that the number of weeds and their weight increased significantly after subsoil tillage. At the budding stage, the number of weeds increased 2.1-fold compared to the control (real tillage), and the weight of weeds increased 1.88-fold. During flowering stage, these indicators were 2.2 times higher. The maximum yield in all variants of the experiment was formed by Elvis cultivar - 44.9 and 41.4 t/ha, respectively, which is more than VEM (standard) and Meteor cultivars by 20.4 t/ha (7.9 %) and 20.0 t/ha (8.7 %), respectively. The yield of Meteor cultivar in these variants was also high and amounted to 41.6 and 38.1 t/ha, respectively, which was higher by 11.5 and 10.4 % compared with the standard. The greatest increase in the fresh yield was provided by real tillage. On average, the yield increased by 8.7 % for varieties in comparison with subsoil cultivation. Elvis cultivar formed the best quality indicators, followed by Meteor cultivar.

In general, the state of seed production in Kazakhstan can be characterized by the following figures. According to Kostanay branch of Kazakh research Institute of mechanization and electrification of agriculture total requirement of seeds is around 2 million tons. These farms provide 70% of the Republic'sfarms with seeds, the remaining 30% are imported from Russia. The studies have shown that all grain-producing regions of Kazakhstan can be classified into three categories according to the annual gross grain harvest, respectively, 16; 15; 3.26 and 2.9 million tons. It is advisable that typical seed farms have the following characteristics: in the first category of regions — the average area of one farm — 2.8 thousand hectares, the average annual grain harvest — 8.06 thousand tons, agro term — 10 days, the required total seed collection -1.78 million tons for all seed farms in the amount of 220 units. Accordingly, in the second category of regions — 1100 hectares; 2.82 thousand tons; 9.5 days 360 thousand tons and 128 units. In a third category — 322 hectares of 1.02 million tons, or 9.1 days, 320 thousand tons and 312 units. Total number of typical specialized farms should be approximately 660 units.

In many regions of the Republic of Kazakhstan, the environmental situation is deteriorating. The total area of the territory of the Republic of Kazakhstan according to the land balance as of November 1, 2013 is 272.5 million hectares. In recent years, under the influence of natural and anthropogenic factors, the volume of pastures has increased per unit area, soil fertility has decreased, irrigation and rainwater nutrients have decreased, salinization and irrigation areas have decreased, crop yields have decreased, and water and soil pollution are increasing, and certain species of flora and fauna are at risk of extinction. Most of the Republic's territory is located in desert zones (60% of the territory). In agriculture, industry and everyday life, the role of hydroponics is increasing. One of the reasons for this is a reduction in the financial costs of tillage, protection from weeds and pests when using the hydroponics method, as well as an increase in a large number of plants on a limited landing site. Water and mineral fertilizers are spent more efficiently due to their repeated use. Growing plants using hydroponics is very profitable, since in a short period of time you can get a crop using year-round and small areas. Here, an important role is played not only by macro-and know the concentration of trace elements. As a result, plants do not realize their potential, and therefore do not always give a high-quality product. The use of hydroponics also reduces the financial costs of soil cultivation, protection from weeds and pests, and will increase the number of plants on the landing site with a limited volume.

A study was carried out to evaluate the effect of head decapitation and planting density on plant growth, seed yield and quality of sprouting broccoli, Brassica oleracea var. italica L. using cultivar ‘Green Head’. The twenty treatments comprised of combinations of four head decapitation methods viz., D1 (decapitation of primary head at appearance and harvesting seeds from secondary heads), D2 (decapitation of primary head at marketable stage and harvesting seeds from secondary heads), D3 (removal of secondary heads at appearance and harvesting seeds primary head) and ‘D4’ (No decapitation- control) and five planting densities viz., S1 (60x60 cm), S2 (60x45 cm), S3(45x45 cm), S4 (60x30 cm), and S5 (45x30 cm). Decapitation of primary head at appearance and harvesting seeds from secondary heads (D1) and planting density S3 (45x45 cm) independently as well as in combination gave highest seed yield per plot and per hectare. This combination was also found comparable to other combinations for other characters like days to 50% flowering, days to seed harvesting, plant height at harvesting (cm), number of branches per plant, number of siliqua per plant, siliqua length (cm), number of seeds per siliqua and seed quality parameters. Therefore, it is suggested that decapitation of primary head at appearance and harvesting seeds from secondary heads (D1) in combination with plant spacing of 45x45 cm i.e. D1S3 can be recommended for commercial seed production of sprouting broccoli.

The article highlights the unique role of irrigation canals in the supply of water in the required amount, depending on crop demand and the rational use of it. The study of the prevention of filtration in irrigation networks and the study of the existing malfunctions in the operation of irrigation networks, the sequence of works on the repair of irrigation networks were analyzed, and the priority of repair work was determined. The current state of the Khumbuz canal in Khiva, Khorezm region of the Republic of Uzbekistan was studied. Information was obtained and analyzed on compliance with design specifications during construction and the presence of protection zones in the canal design. Analytical indicators have been developed to extend the service life of the Khumbuz canal to ensure its normal operation and supply the required amount of water to crops. In the implementation of water supply to agricultural crops, priority is given to the repair and construction of hydraulic structures, including the Khumbuz canal. In addition, all the work to be done was planned based on the priority of the work. It has been found that the amount of water required to irrigate crops can be achieved uniformly along the length of the canal, at the top, middle, and bottom of the canal, by ensuring that the irrigation networks operate at the required level. Specific scientific recommendations have been given for the normal operation of the Khumbuz canal. Repairing the canal has been shown to increase water use by 20 percent and increase crop yields by 15 percent by ensuring that crops receive the required amount of water on time. The service area of the Khumbuz canal is 1.460 hectares. The length of the canal to be repaired is 6 km. of which 2,568 km of new concrete. The maximum water flow of the canal is 2.5 m3/sec, and the normal water flow is 2.0 m3/sec. The efficiency of the channel (canal) is 0.93. The article provides information on how to achieve efficient use of irrigation water by repairing hydraulic structures at the required level and the construction of new ones.

Hybrid breeding facilitates the exploitation of heterosis and it can result in significant genetic gains and increased crop yields. Inefficient cross-pollination is a major limiting factor that hampers hybrid wheat seed production. In this study, we examined the genetic basis of anther extrusion (AE), which is an important trait in increasing cross-pollination, and thus improving seed set on the female lines and hybrid wheat seed production. We studied 300 segregating F2 plants and F2:3 families that result from a cross of two elite spring wheat lines. We observed that F2 and F2:3 populations hold significant and continuous genetic variation for AE, which suggests its reliable phenotypic selection. Composite interval mapping detected three quantitative trait loci (QTL) on chromosomes 3A, 5A, and 5D. The QTL on chromosome 5A (i.e., QAe.cimmyt-5A) was of large-effect, being consistently identified across generations, and spanned over 25 cM. Our study shows that (1) AE possesses strong genetic control (heritability), and (2) the QTL QAe.cimmyt-5A that imparted on an average of 20% of phenotypic variation can be used for marker-assisted selection (MAS) in breeding programs. In addition, pyramiding the large-effect QTL for MAS could efficiently complement the phenotypic selection since it is relatively easy and cheap to visually phenotype AE. This study reports the first large-effect QTL for AE in spring wheat, endorsing the use of this analysis in current hybrid wheat breeding and future Mendelization for the detection of underlying gene(s).

Increasing crop yields involves the introduction of not only mineral, but also organic fertilizers into the soil. The disposal of manure of large livestock complexes in adjacent fields in combination with irrigation is of particular relevance at present. This allows, on the one hand, to reduce the load on treatment facilities, and, on the other hand, to improve the soil fertility of adjacent farmland. The article presents the results of monitoring the hydrogeological and reclamation state of the lands in the state farm «Roschinsky» in the Sterlitamak district of the Republic of Bashkortostan irrigated with wastewater from the livestock complex. It is revealed that for the periods from 1987 to 1997 irrigation with wastewater caused an increase in the mineralization of soil solutions from 0,007–0,096 to 0,34–0,45 %. The accumulation of sodium, magnesium, calcium, sulfate and chlorine ions in soils took place. The capacity of the soil-absorbed complex decreased from 49,8 to 12,8 mEq/100 g. Under the influence of irrigation with sewage, the chemical composition and salinity of the groundwater underwent significant changes. The content of sulfates (from 20–40 to 150–350 mg/l), chlorine (from 10–20 to 100–200 mg/l), sodium (from 10–50 to 70–100 mg/l) increased. The mineralization increased from 0,6–0,7 to 1,4–2,7 g/l. The deterioration of soil properties was also observed in the subsequent observation period from 2006 to 2010. Exceeding the boundary value of the dry residue for non-saline soil (0,25 %) in the meter soil layer was noted in 2010 at 9 out of 10 observation points, while in 2006 – only at 1 observation point. The total amount of water-soluble salts in a meter layer of soil from 2006 to 2010 increased by 14,2 t/ha, including toxic salts by 9,57 t/ha. To prevent the further development of salinization processes, the disposal of livestock stocks must be alternated with seasonal preventive leaching of the soil against a background of closed horizontal drainage, as well as increasing the area of the irrigated area and including salt-resistant crops in the rotation.
