THE IMPACT OF PHOTOSYNTHETIC ACTIVITY OF EARLY POTATO SOWING IN CROP FORMATION IN THE CONDITIONS OF THE SOUTH OF KYRGYZSTAN

abstract 1521908013 issue 152 pp. 117 – 128 31.10.2019 ru 201
This article presents the results of studies on the impact of the fertilizer application rate and the use of the growth stimulant called Bereke GN on photosynthetic activities of early potatoes in southern Kyrgyzstan. Due to the lack of scientific evidence on the integrated use of fertilizers and growth stimulants in conditions of southern Kyrgyzstan, we considered it necessary to clarify the methods and standards for the use of the Bereke GN growth stimulant in the production of early potatoes in lowland areas on typical gray soil. In southern Kyrgyzstan, similar research in early potato technology is being carried out for the first time. According to studies, the crops of early potatoes possessed high leaf surface, which were subjected to complex treatment of the Bereke GN growth stimulator, accordingly its value was in the flowering phase of 41.2- 48.2 thousand m2. When the nutrition increases, a more powerful assimilation surface is formed. The highest level was 48.2 thousand m2 per 1 ha under the complex treatment with growth stimulator. The formation of tuber mass on 1 bush with the complex use of the Bereke GN growth stimulant showed a high intensity. With an increased nutrition, the Berke GN Growth Stimulator Integrated Test Variant increased the tuber formation rate, respectively the value was 182 g/bush. According to studies over the years of the experiments, the amount of dry biomass crops increased naturally, depending on the application of fertilizers and the use of the growth Bereke GN stimulant

abstract 1521908016 issue 152 pp. 200 – 210 31.10.2019 ru 175
To increase productivity and quality, as well as to reduce the cost of production of winter wheat in the Central irrigated zone of the Rostov region is of great importance to find the most effective methods of agricultural culture, in particular, the protection of crops from weeds. The work determines most effective herbicides for pre-germination use against annual dicotyledonous, including resistant to 2,4-D and MCPA, and some perennial root-spray weeds in the Central irrigated zone of the Rostov region. The efficiency of different terms of application of the herbicide called Ballerina on winter wheat crops in the Central irrigated zone of the Rostov region was studied. The greatest biological effectiveness of herbicides is provided by spraying winter wheat crops in the tillering phase with Ballerina herbicide with the norm of 0.3 l/ ha. We have discovered low biological effectiveness of Gerbitox herbicide against Matricaria inodora (L.), Fumaria officinalis (L.), Artemisia vulgaris (L.) and Cirsium arvense (L.). Best experience quality indicators of winter wheat grain were observed in the variant with the lowest contamination of crops when spraying in the phase of tillering a Ballerina herbicide 0.3 l/ha. The content of trash was 7.1%, nature 790 g/l, gluten content of 26.4 %, group 2 quality, and the commodity class – 3. Good quality indicators were also observed in the variant with Ballerina herbicide treatment of 0.5 l/ha in the tube exit phase. The highest level of profitability was obtained when spraying winter wheat crops in the tillering phase with Ballerina herbicide 0.3 l / ha-116%, and the lowest on the control was without treatment with herbicides - 74%

abstract 1521908020 issue 152 pp. 240 – 248 31.10.2019 ru 201
This article reviews the results of studies on the impact of the nutrition background and the use of the Bereke GN growth stimulator on the yield and quality of early ripe potato variety Marabell in southern Kyrgyzstan. Early potato yields were largely dependent on the use of the Bereke GN growth stimulant. The highest yield was identified with the integrated use of a growth stimulator provided the planned yield, and averaged 29.97 t/ha. Also, in the experiments conducted, the yield of early potatoes was largely dependent on the climatic conditions of the year under study. The structure of the crop of early potatoes has been analyzed. In case of complex application of growth stimulator, also in case of treatment of seed tubers with growth stimulant, thickness of early potato plants is increased and on average in three years there was an increase by 0.32 and 0.52 thousand bushes per 1 ha. The structure and marketability of the early potato harvest were analyzed in detail, depending on the background of nutrition and the method of application of the Bereke GN growth stimulator

RICE QUANTITATIVE TRAITS CONTROLLING YIELD AND THEIR INHERITANCE

abstract 1511907002 issue 151 pp. 15 – 23 30.09.2019 ru 185
Rice is a crop with high yields guaranteed by nature itself. In recent years, huge changes have occurred in the domestic rice cultivation, but despite this, there are still a lot of unsolved relevant problems. One of such problems is the development of high yielding varieties. The success of breeding largely depends on the availability of genetically diverse starting material with a wide response to changing environmental conditions, its knowledge and proper selection; as well as the identification of new sources of valuable traits and properties, among ecologically remote agro-types that enrich the genetic potential of domestic varieties. Development of a high-yielding variety is greatly influenced by economically important traits: plant height, total and productive tillering, the number of spikelets and grains in the panicle, grain size, weight of 1000 grains, etc. In modern biological science of heredity, there is still the question of the inheritance of quantitative traits. The study of inheritance of quantitative traits constituting the main elements of the yield structure is one of the most important tasks, the solution of which is necessary to speed up the breeding process. Inheritance of any trait is often determined by researchers by the magnitude of the dominance coefficient

APPLICATION OF HYDROCARBON SUB-STANCE OF GROWTH AT CULTIVATION OF CROPS

abstract 1511907004 issue 151 pp. 33 – 45 30.09.2019 ru 207
In this work we have given the analysis of the literary data confirming positive experience of impact of the hydrocarbon substance of growth (HSG) on viability of seeds, resilience, growth of plants, and productivity of various crops. It is shown that the basic experimental data belong to the 60th of the XX century. At the same time, works on application of HSG have been generalized for the first time in the collection of works of the Academy of Sciences of the Azerbaijani SSR by Institute of soil science and agrochemistry. HSG represents the by-product of petro processing received at sulphuric acid cleaning of diesel fuel with further processing with alkaline solution of NaOH. It includes mainly mixture of sodium salts of naphthenic acids. On the basis of literary data and own probes it is established that for each culture there is optimum very small concentration of HSG (0.005-0.01%), processing by solution of which makes positive impact on viability, growth and development of crops. The results of probes of blood formation of animals [8] and growth of mass of birds allow considering HSG ecologically safe. We have also presented the results of pilot study of impact of pre-seeding processing of seeds of wheat and peas by water solutions of the hydrocarbon growth substance (HSG) on their morpho-physiological parameters. The most effective concentration of HSG for processing of seeds of spring wheat of grade "Saratov" and grade peas "Alpha" is revealed. It is shown that the stimulator in concentration of 0.005-0.01% proves as stimulator of crop growth. It follows that degree of efficiency of action of HSG on improvement of development and increase in productivity of agricultural products from use of this drug is quite high. Considering that the stimulator can be received at insignificant expenses as a waste product of the purified diesel fuels, its application in agriculture is economically justified
