EFFICIENCY OF HERBICIDES APPLICATION ON WINTER WHEAT CROPS
DescriptionTo 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%

Description
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

Description
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

Description
As a prospect in baking, a number of researchers propose to expand the range of products in the formulation of which include natural food dressers. The article presents the results of research on the development of the optimal formulation of bread from mixtures of wheat flour, wholemeal flour from grains of naked barley varieties Nudum 95 and wholemeal flour from grain triticale varieties Tsekad 90. To select the optimal mixture of wheat, barley and triticale flour, the following variants of the ratios were studied– 70:10:20; 60:20:20; 50:30:20; 50:20:30. As control we took flour of the highest grade from grain of strong wheat Novosibirsk 29. Flour mixtures studied by the gluten content is significantly inferior to the control version of the flour. In the version where 70% of wheat flour was used, gluten decreased by 5.1%, in the version with the amount of wheat flour 60%, gluten decreased by 8.0%. In subsequent variants, the difference in gluten content with the control variant was more than 10%. The lowest rate of flour strength (145 e.a.) in the version where barley flour reached 30% of the mixture. In other embodiments, the flour strength level 209-250 e.a., that is slightly different from the standards on valuable wheat (not less than 260 e.a.). In terms of baking quality has distinguished the case where the proportion of wheat flour was 70%, barley – 10% and triticale – 20% (the volume of bread 500 ml, total score of bread 4 points). In subsequent versions, the performance of baking qualities decreased. As a result of evaluation of mixtures of wheat, barley and triticale flour revealed the most optimal ratio – 70:10:20. This option is recommended for introduction into production for enrichment of wheat flour with nutritious components of barley and triticale grain
