INFLUENCE OF ALTERNARIA SPP. FUNGI METABOLITES ON DEVELOPMENT OF WHEAT SPROUTS

The study purpose was in vitro investigation of phytotoxic activity of culture broth filtrates (CBFs) of five Alternaria Spp. fungi isolates on development of wheat sprouts. Fungi isolates were received from wheat seeds cultivated under conditions of Northern Kazakhstan. According to the study findings, culture filtrates of all the isolates studied varied with regard to their influence on wheat sprout development. Stimulant effects on seed germinating power were revealed with 14- and 21-day CBFs of A. infectoria (7/4), 14-day CBF of A. brassicae (7/2) and 21-day CBF of A. porri (8/1). It was found that long-term cultivation of fungi on a culture medium contributed to media pH modification towards alkalization due to production of metabolites of various chemical nature, including toxins, which could trigger growth inhibition of radicles and sprouts. However, the CBFs were predominantly low-toxic or non-toxic. Under effect of the 14-day CBF, significant positive correlation was identified between pH values and sprout lengths (0,86±0,25), while negative correlation was found between pH values and germinating power (-0,75±0,33). Change of pH value on the 21st day significantly affected radicle length (-0,92±0,20). Based on the findings it can be concluded that the 14-day CBF of all the Alternaria fungi isolates studied was most toxic for wheat sprouts.

Soil Microbiota and Particulars of Formation thereof under Traditional and Organic Farming on Chernozem Soils of Northern Kazakhstan

The subject matter of the study is soil microbiota of southern carbonate chernozem and particulars of formation thereof under organic and traditional methods of wheat growing under conditions of Northern Kazakhstan. It has been found that soil microbiota varies with arable farming systems. Application of leguminous and cereal above-ground biomass as organic fertilizers contributed to higher numbers of immobilizers that were twice as high as traditional farming variants. When applied as green manure, sweet clover above-ground biomass increased the number of ammonifying soil organisms (up to 6 million CFU/g a.d.s.), while bromegrass biomass increased the number of immobilizers (83.0 million CFU/g a.d.s.) and fungi (8,0 thousand CFU/g a.d.s.). Cellulose-destroying microorganisms were actively propagating in wheat crops (65.0 CFU/g a.d.s.) where wheatgrass biomass was applied as green manure, while sweet clover biomass, on the contrary, contributed to decrease thereof. Under traditional farming conditions, the introduction of ammonium nitrate into rows when planting crops at a dose of N80 stimulated the development of cellulolytic microorganisms and inhibited the development of ammonifying fungi and bacteria. Ammonifiers and immobilizers were actively propagating with reserve application of ammophos in the fallow at the rate of P40.

Assessment of the genetic parameters of soybean genotypes for precocity and productivity in the various cultivation conditions

Soybean (Glycine max [L.] Merr) plays a crucial role in the advancement of agriculture in Kazakhstan, serving as a promising food crop and feed source. The primary challenge in boosting soybean production in Northern Kazakhstan lies in the absence of soybean cultivars suited to the region's conditions. As such, the foremost focus of breeding initiatives should be on creating soybean varieties that possess both early maturity and satisfactory yield potential. The objective of this research was to assess the impact of maturity time (MT) on both the yield formation and the adaptive characteristics of soybean varieties from different origins. This evaluation was conducted by analyzing the outcomes of their testing under diverse cultivation conditions in the northern region of Kazakhstan. The soybean cultivars that were examined, originating from various sources, were classified into three primary groups. These groups varied in terms of their growing season duration as well as their yield levels. The way the alleles of the E1–E4 flowering genes were spread out in the identified clusters showed that for soybean varieties where recessive alleles of the E1–E4 genes build up, the growing season usually shorter. Cultivars of Chinese, Russian, and domestic selections isolated as a result of the research were good initial material for use in local breeding programs. Within the framework of the clusters, an environmental assessment of soybean accessions was carried out, which made it possible to determine their degree of plasticity and, in general, their adaptive potential in the conditions of Northern Kazakhstan. The best cultivars were the Chinese selection ‘Dongnong 63’ and the Russian selection ‘SIBNIIK 315’. Hence, the present study successfully discovered soybean cultivars that possess exceptional adaptability and flexibility. These cultivars hold significant potential for cultivation and practical use in the specific environmental circumstances of northern Kazakhstan.

Justification of the Use of Container Technology in Dumping

The increase in the depth of the quarry is associated with an increase in the work of quarry transport in limited areas, requires a constant increase in the number of transport units, which increases the environmental burden on the environment. The rock mass extracted from the quarry is stored in external dumps, which occupy large areas and significantly worsen the ecology of the region. The operation of mining equipment on dumps with existing technologies causes a number of problems, the main of which is the movement of equipment near the prism of a possible rock collapse. It is proposed to use container technology for transporting the laying rocks in the dump, where the main element of the technology is a mobile lifting machine, which eliminates the need to build roads or railways on board and on the surface of the dump. Self-unloading of container equipment allows you to pour the rock mass directly to the place of laying on the dump. Containers with rock are installed in front of the front of the dump, and the lifting machine is placed on a special platform of the dump. The rock mass is delivered from the faces by dump trucks of any load capacity and unloaded into the hopper of a plate feeder, which fills the containers as they are fed by a quarry lifting machine. the rock is laid in horizontal layers within the step of moving the lifting machine. The weighted average height of the rock rise is equal to half the height of the dump tier. With the new technology, the entire amount of work will be performed by one lifting machine. Increasing the height of the dump to 80 meters with a new method of dumping, reduce the area occupied by dumps by 175 thousand m2 per year. The use of container technology in the formation of the dump allows, when unloading rock from containers into the dump, to reduce energy consumption during the formation of the dump, and increase the economically advantageous height of the dump. This reduces the area occupied by dumps and reduces the harmful effects of mining on the environment. The article discusses the technology of dumping during the formation of dumps using bulldozers in the conditions of Northern Kazakhstan. Traditional technology involves the involvement of a complex of equipment consisting of 8 dump trucks and 1 bulldozer. According to the new technology, the same amount of work can be done thanks to 1 lifting machine. Based on the calculations carried out, it was found that the intensity of dust emissions from internal sources decreases by 1,576 tons per year. A decrease in dust emissions is also observed with an increase in the height of the dump due to a decrease in area, while the difference was 75.57 tons per year. The total decrease from container technology is 1,651.57 tons per year.

GENOME-WIDE ASSOCIATION STUDY FOR GRAIN QUALITY TRAITS IN SPRING BARLEY COLLECTION GROWN IN NORTH KAZAKHSTAN

Barley is a cereal crop that is grown all over the world. Its grain is used for animal feed, malting, brewing, and food. The quality of barley grain is important, particularly raw starch and protein contents, and it depends on the end-use product. This study looked at a collection of 356 barley accessions from the USA and Kazakhstan grown under conditions of northern Kazakhstan (Karabalyk agricultural experimental station) and genotyped with 1631 polymorphic SNPs markers. The collection was studied for starch (GSC), protein (GPC), cellulose (GCC), and lipids contents (GLC), and for grain test weight (TWL) during two years. Phenotypic analysis demonstrated impact of the year on studied traits and significant associations between grain quality and the yield (P < 0.01). Population structure analysis revealed three subclusters in the studied barley collection with the dominance of the USA’s barley in two of them. As a result of GWAS, 22 significant QTLs (P < 0.001) were identified for the studied grain quality traits including 19 single-trait QTLs, 2 double-trait QTLs, and a one triple-trait QTL. For 16 QTLs, reference quality genes and/or QTLs were found, while the remaining 6 QTLs were presumably novel genetic factors for grain quality traits. As result, these 22 QTLs are expected to be useful for future breeding projects targeting the selection of high grain quality barley cultivars.

Abstract. The purpose is to assess the adaptability of sugar sorghum genotypes in various agro-climatic zones of cultivation. Methods. The reaction rate of 8 samples of sugar sorghum selected by Russian Research and Design-Technological Institute of Sorghum and Corn was evaluated based on the results of the 2020–2022 test in two ecological points: Saratov (Russia, Saratov region) and Kokshetau (Kazakhstan, Akmola region), characterized by different climatic conditions. Methods of cultivation of plants, accounting for yields are generally accepted for sorghum. The repetition in the experiment is threefold, the placement of plots is randomized. Results. According to the results of statistical analysis, the share of the studied factors in the overall variability of traits was established: the greatest contribution to the “plant height” and “biomass yield” was made by the factor “ecological testing point” (33.6–58.0 %), in the “area of the largest leaf” – “genotype” (31.3 %). It was found that in the conditions of Northern Kazakhstan, characterized by lower heat and moisture availability during sorghum testing (the difference in the sum of active temperatures reached 466.2–769.9 °C, and precipitation – 17.0–106.1 mm in comparison with the conditions of the Lower Volga region of Russia), the area of the largest leaf increased by 10.6 cm2 on average for the group of genotypes studied at the same time, the height of plants and the yield of vegetative mass decreased by 22.2 cm and 11.26 t/ha, respectively. At the same time, varieties and hybrids have been identified that form a biomass yield of 20.54–21.44 t/ha on average during the test period – Chayka, Volzhskoe 51, Sakhara, Kalibr. Scientific novelty. For the first time, the possibility of growing varieties of sugar sorghum selected by Russian Research and Design-Technological Institute of Sorghum and Corn in the conditions of Northern Kazakhstan is presented. Thus, according to the complex of adaptability parameters in combination with high biomass productivity, on average, the Volzhskoe 51 variety was selected for the points of environmental testing.

Factors affecting the cost of grain transportion in Northern Kazakhstan

The article considers the factors influencing the cost calculation for thegrain transportation in the conditions of Northern Kazakhstan. Grain production is the leading branch of agriculture in Kazakhstan. Therefore, it has great strategic importance in implementing priority state programs aimed at developing the agro-industrial complex and rural regions. In turn, the sustainable development of agriculture is the provision of the food security strategy of Kazakhstan. The grain industry is costly due to substantial production volumes, the involvement of many human resources, technical support, and transportation. Minimizing grain transportation costs by identifying factors affecting them will increase competitiveness and accelerate the development of grain logistics. When planning for harvesting and transporting grain, it is necessary to consider the peculiarities of transporting agricultural goods. Finally, implications for pricing, capacity, and understanding the basis of pricing are discussed.

Study of Plant Growth and Essential Oil of Nepeta cataria L. in Kazakhstan

The genus Nepeta exhibits a wide spectrum of biological activity in medicine, agriculture, and the food industry. The purpose of the research is to develop the optimal agricultural technology for plantation cultivation of Nepeta cataria L. with the preservation of useful properties and to increase the content of essential oil in the conditions of Northern Kazakhstan. The objects of research are annual plants N. cataria L. growing on a plantation in the Akmola region. It has been reliably proven that the increase in the growth of N. cataria L., the biomass, and the yield is positively affected by the application of complex fertilizer N100P80K120. The essential oil yield was 0.52% in the experiment without fertilizers and 0.57% in the experiment with fertilizers. The main components of the essential oil of N. cataria L. grown in the experimental plots (plot #1 and plot #2) were 4aα7α7aα-Nepetalactone (76.5612 and 79.3200%), β-caryophyllene (4.0001 and 4.0351%) and caryophyllene oxide (1.9789 and 2.5969%). The remaining components were contained in the essential oil in small quantities. The composition of the essential oil of plants from Kazakhstan was similar to the composition of the essential oil of plants from central Iran, Egypt, and Korea, because the main substance was nepetalactone. The conducted studies prove the success of growing catnip in the conditions of Northern Kazakhstan.

The article presents the results of conducting primary seed production of virus-free original and zoned potato varieties in the conditions of Northern Kazakhstan. The creation and introduction into the production of new virus-free highly productive potato varieties with a complex of economically valuable traits is a priority for the national economy of any state. Providing potato-growing farms with high-quality seeds of local varieties has been and remains an acute problem for the industry. The data on the yield and quality of tubers depending on the reproduction of potatoes are presented. So, when assessing the yield of virus-free potato varieties, a good indicator was observed in Dunyasha (12.7 t/ha), Zeren (9.2 t/ha), and Sante (6.4 t/ha). When harvesting from an area of 0.6 ha, 3.4 tons of super-elite potatoes were harvested with an average yield of 5.7 t/ha.

ФЕНОЛОГИЧЕСКИЕ ОСОБЕННОСТИ СОРТОВ И ГИБРИДОВ СОРГОВЫХ КУЛЬТУР В УСЛОВИЯХ СЕВЕРНОГО КАЗАХСТАНА

Sugar sorghum and sorghum-sudangrass hybrids are rare crops in Northern Kazakhstan. One of the constraints to the introduction is the low range of varieties and hybrids adapted to the climate of a region characterized by heat, moisture and a short frost-free period. Now an important factor is the selection of short-season variety and hybrids able to achieve: milky-wax ripeness (for feed); wax and complete ripeness (for seeds). Nine varieties of sorghum sugar and seven sorghum-sudangrass hybrids were used as research target. Experiments were carried out in 2020-2022 on the practice field of Kokshetau University named after Sh. Ualikhanov. Research has revealed varieties capable of ripening to complete ripeness of seeds: Capital (growing period on average 101 days) and Volunteer (103 days). Also, varieties ripening to wax ripeness are defined: Seville, Sahara, Volzhskoe 51 and Chaika. Under regional conditions, the optimum period from seeding to flowering should be considered 70-75 days. Studied sorghum-sudangrass hybrids did not have time to form seeds and are recommended for hay, and green feed. The results of the research show the possibility to select sugar sorghum under the conditions of Northern Kazakhstan, and open the prospects for local varieties.

ГРЕЧИХА ПОСЕВНАЯ (Fagopirum esculentum) КАК ИСТОЧНИК РУТИНА НА СЕВЕРЕ КАЗАХСТАНА

The article presents the results of studies of buckwheat (Fagopyrum esculentum Moench) plants as a source of bioflavonoids – biologically active compounds of polyfunctional action. Buckwheat is the only agricultural crop in Kazakhstan that contains rutin. Modern pharmacological studies show that rutin helps lower blood cholesterol levels, exhibits high antioxidant activity and is used in the treatment of many chronic diseases. In the process of research, the gene resources of buckwheat (varieties, hybrids, populations) were studied and the content of rutin in the aerial parts of plants was determined. The dynamics of rutin accumulation in buckwheat plants was revealed, the presence of a relationship between the content of rutin and the main breeding and economic traits was established. A promising source material with a high content of rutin has been isolated for use in the breeding process. For the first time, the quantitative parameters of the content of rutin at various stages of the ontogenesis of buckwheat in the conditions of northern Kazakhstan were determined. The phases of plant development with the maximum concentration of rutin have been established. The initial material of buckwheat with a high content of rutin was evaluated for a complex of useful features. The variability of the color of the plant and grain (nucleus) as a marker for the selection of plants with a high content of rutin was studied. As a result of the research, the possibility of using the entire vegetative mass of buckwheat (flowers, leaves, stem) of various biotypes as a raw material for the production of rutin with the extraction of the target product has been shown.

ПРОДУКТИВНОСТЬ И КАЧЕСТВО СОРТОВ СОИ ИЗ МИРОВОЙ КОЛЛЕКЦИИ В УСЛОВИЯХ СЕВЕРНОГО КАЗАХСТАНА

The article summarizes the results of a long-term study of soybean varieties from the world collection in the North of Kazakhstan, in the Kostanay region on the experimental fields of LLP "SKOS "Zarechnoye". In the period from 2020 to 2022, about 250 varieties of various ripeness groups from the world soybean collection were screened. An assessment of their ability to form a crop in the conditions of Northern Kazakhstan was carried out. Full filling of seeds during the years of research of the collection was achieved in most cases by cultivars created by breeders of the northern countries of the world, since they have low photoperiodic sensitivity, are not oppressed by low temperature, but at the same time are sensitive to excess precipitation. The protein content in the seeds of the studied soybean samples belonging to the precocious group varies from 37.8 to 41.1%. The highest indicator is in the Hay Hek variety 14 (41.1%). But among all the numbers of the collection, the leading indicators are: 126/1, 186/1, Zlata and Pitket K6298, respectively 44.2%, 44.3%, 44.5 and 45.4%. The high protein content in soybean seeds can be explained by their high ability to symbiotic nitrogen fixation. The studied gene pool has been characterized by a number of characteristics and can serve as a valuable source material for the creation of varieties recommended for cultivation in the North of Kazakhstan.

VALIDATION OF MARKER-TRAIT ASSOCIATIONS IN SIX-ROWED BARLEY LINES BRED IN KAZAKHSTAN

Barley is an important cereal crop in Kazakhstan, mostly used for animal feeding, malting, and the food industry. The success of barley production is dependent on the genetic resources (cultivars) available, and local breeding programs that focus on the development of competitive cultivars. One way to develop new high-yielding cultivars and improve the efficiency of breeding programs is the application of modern molecular genetic and genomic tools. One such technology is genome-wide association study (GWAS), which has been successfully applied to identify the quantitative trait loci (QTL) associated with the valuable traits. The identified single nucleotide polymorphisms (SNPs) based on GWAS can be converted to flexible and cost-effective KASP (Kompetitive Allele Specific PCR) assays and validated for use in future marker-assisted breeding projects. The purpose of this study was to genotype eleven promising six-rowed barley lines using twenty-one KASP assays associated with agronomic traits reported in previous GWAS. The genotyping results suggested that only seven out of twenty-one KASP markers were polymorphic in this group of barley accessions. The t-test output suggested that six out of nine agronomic traits were significantly associated with seven KASPs. Notably, two assays (ipbb_hv_6, ipbb_hv_108) affected both vegetation period (VP) and yield per m2 (YM2) in conditions of Northern Kazakhstan, where barley is growing in more than 80% of total crop sowing areas of the country. The application of these highly informative KASP markers can help enhance the efficiency of local breeding projects in barley.

Grain quality of spring wheat (<i>Triticum aestivum</i> L.) cultivars developed in Western Siberia under the conditions of Northern Kazakhstan

Background. Environmental testing is the first stage of wheat breeding, the purpose of which is to identify wheat samples suitable for local environments and capable of forming a fairly stable yield and high-quality grain. The proposed study presents the test results for spring bread wheat cultivars of Russian breeding grown in arid environments of Northern Kazakhstan in order to preserve their yield and baking qualities.Materials and methods. The material of the study included 15 spring bread wheat cultivars. Protein and gluten content and the quality of gluten were determined using an infrared analyzer; the physical properties of the test were assessed using a Chopin alveograph and Brabender farinograph.Results. As a result of biochemical assessment, increased protein and gluten content and grain weight were observed in cvs. ‘Tyumenskaya 30’, ‘Aviada’, ‘Lutescens 585’, ‘Serebrina’, and ‘Tyumenets 2’. Dough deformation energy (W) characteristic of high-quality wheat and the balance in the P/L ratio (elasticity/elongation) were shown by cvs. ‘Tyumenskaya 33’ (290 a.u.; 1.15 P/L), ‘SKENT-3’ (307 a.u.; 0.89 P/L), and ‘Lutescens 585’ (374 a.u., 1.10 P/L). In laboratory baking, the volume of bread ranged from 620 ml (‘Tyumenskaya 27’) to 768 ml (‘Tyumenskaya 29’) with an average value of 707 ml. A baking quality analysis of the cultivars grown in the Northern Trans-Urals and Northern Kazakhstan demonstrated that the conditions in Northern Kazakhstan were more favorable for obtaining bread with an increased volume. On the basis of environmental tests and an assessment of a set of biochemical and technological indicators, cvs. ‘SKENT-3’ and ‘Tyumenskaya 29’ were selected. It makes sense to continue studying wheat cultivars that can be sources and donors of high-quality grain for the development of cultivars for the arid steppe of Northern Kazakhstan.

ECOLOGICAL TESTING OF SPRING SOFT WHEAT VARIETIES IN THE CONDITIONS OF NORTHERN KAZAKHSTAN

One of the most vital selection issues is creation of wheat varieties adaptive to certain soil and climatic conditions. Ecological testing plays an important role in evaluation of new source material and development of varieties. The aim of our research is to study samples of spring soft wheat of various ecological and geographical origin by a complex of economically valuable traits in the conditions of Northern Kazakhstan. The object of the study was 52 varieties of spring wheat of various ecological and geographical origin from 20 institutions of Russia and Kazakhstan. Sowing was carried out on fallow at appropriate time for the zone in two repetitions. The plot area was 5 m2, seeding amount was 3.5 million of viable seeds per hectare. Agrotechnics of the experimental plot was carried out in accordance with recommendations for spring wheat cultivation in Akmola region. Along with making record of the yield data, the duration of the growing season was also determined, the grain was assessed by the content of protein, gluten and FDM. Phenological observations, records and evaluation of samples were carried out in accordance with recommendations of KASIB system, which are based on All-Russian Institute of Agriculture method. According to the research results of 52 varieties and lines of different ecological and geographical origin in the conditions of Northern Kazakhstan, it was established that these samples differed in types of ripeness, yield and formation of quality parametres. On average for 2019-2021, Line 67/98-13 (Scientific and production center of grain farming named after A.I. Baraev) matured the earliest - 85 days. The maximum yield was formed by Pamyati Azieva variety (International standard) - 24.2 dt/ha, high protein content - 19.39% was noted in the line Erythrospermum 79/07 (Karabalykskaya Agricultural Test Station). Line 67/98-13 (Scientific and production center of grain farming named after A.I. Baraev) has a high content and quality of gluten - 37.5%, 75 units of FDM. It is recommended to use the samples distinguished for this or that trait in this zone for creation of new source materials.
