APPROACHES TO JUSTIFICATION OF AN EXPERT SYSTEM IN THE DEVELOPMENT OF EPIPHYTOTICS ON WINTER WHEAT CROPS

abstract 1181604103 issue 118 pp. 1576 – 1586 29.04.2016 ru 495
The article examines the creation of the expert system in the development of epiphytotics in winter bread wheat sowing. Increasing the accuracy of the forecast epiphytotics should be based on the improvement forecasting of move daily temperature (minimum, maximum and average). In this case, the calculation algorithm must not be cumbersome. In the algorithm, there are indicators of cyclical annual variations of temperature, i.e. the change in average daily temperatures for the year. For the treatment method of local forecast of daily average temperatures during the year used data of meteorological station for 9 years. Having considered the main issues to epidemics of brown rust and its influence on the production of wheat cenoses, you can proceed to the modeling expert logic. The analysis includes the following indicators: cultivated variety; agricultural machinery (predecessor, fertilizer, pre-processing, and others.); general condition of sowing; phase of plant development at the time of the field survey; date of onset of the disease (if selected); prevalence of sowing at the time of observation. Installed that the purposeful creation of varieties of winter wheat resistant to the pathogen, it is necessary to carry out environmental testing stability as a latent breeding and recommended sources and sustainability of donors, which will allow to plan economic occupancy resistant genotypes of winter wheat

The purpose of the research is to compare the effect of a new symbiotic feed supplement created based on propionic and lactic acid bacteria with a widely used domestic and foreign enzyme-probiotic preparations in chickens 0-28 days of age of the Lohmann Brown egg cross. In the experiment, there were six groups of chickens: group 1 received basal diet (BD); group 2 – BD + symbiotic preparation; group 3 – BD + Bacell; group 4 – BD + Agrocell; group 5 – BD + Agroksil; group 6 – BD + Ollzaym Vegpro. Average daily gain, food conversion rate per 1g of weight gain, digestibility of organic matter, crude protein, crude fiber, crude fat, made up respectively: group 1 – 8.17, 1.91, 71.4, 58.3, 68.0, 81.1; group 2 ˗ 8.36, 1.90, 72.4, 60.2, 69.7, 88.1; group 3 – 8.13, 1.91, 73.1, 60.2, 69.7, 88.1; group 4 – 8.33, 1.86, 74.2, 62.5, 72.2, 87.6; group 5 – 8.50, 1.83, 77.3, 64.1, 73.4, 95.4; group 6 – 7.91, 1.92, 73.2, 67.5, 70.7, 94.3. The growth rate of chickens fed with symbiotic feed supplement was 2.3% higher than in the control and they showed the highest fiber digestibility. The chickens on diet with Agroksil enzyme efficiently raised growth rate (+4%) and reduced feed costs (-4.2%). Agrocell increased weight gain by 2% and reduce feed costs by 2.6%. The growth rate of chickens fed Ollazaym Vegpro was the lowest (96.8% of control), despite the fact that it increased significantly the digestibility of crude protein, but slightly improved the digestibility of other nutrients. Outcome: symbiotic feed supplement may be of interest as a means of increasing the productivity of chickens

ACCELERATED REPROCESSING TECHNOLOGY FOR RECYCLING PIG MANURE INTO ORGANIC FERTILIZER

abstract 1331709080 issue 133 pp. 1094 – 1113 30.11.2017 ru 490
The article considers the accelerated reprocessing technology for recycling pig manure into organic fertilizer. Today, closely relevant is the matter of environmentally friendly technologies for cattle manure utilization. Export of wastes in its pure form to agricultural land cannot be applied, because disease causing and chemical compound penetrated the soil, entered the groundwater and contaminated many water sources. Experiments for the accelerated reprocessing of the pig manure into organic fertilizer were conducted on the basis of PCF No. 2 of the APC "Maryanskaya" in the Krasnoarmeisky district. With the aim of eliminating the filtering of pollutants in soil and groundwater, the experiment was performed in a concreted area, located within a farm. For the test, we used pig manure of animals, whose age was 2-8 months. The total weight of used manure was 40 t. The accumulation of manure was carried out in containers, containing 4 tons; the total time for the accumulation of necessary amount of manure for 2 months. Comparing the quality of compost obtained by the proposed technology recommended for industrial applications, control, we found differences in the chemical and biological properties. Overall, the conducted experiment has allowed to establish that the best option, given the speed of the flow of chemical and biological processes, demands environmental protection, is composting manure with straw, adding a biological product "Tamir" at the rate of 0.5 l/t. The Obtained results are comparable with data of previous years and indicate the possibility of reducing the quantity of a biological product from 1 to 0.5 l/t of waste without reducing the efficiency of the process of accelerated decomposition of nitrogenous organic compounds

STUDYING THE REPRODUCTIVE POTENTIAL OF PLANTS OF BEZOSTAYA 1 WHEAT HAVING ADDITIONAL SPIKELETS ON THE LEDGE OF THE RACHIS

abstract 1201606046 issue 120 pp. 664 – 674 30.06.2016 ru 485
The article discusses the effect of additional spikelets in the variety of Bezostaya 1 on the realization of productivity of the examined plants. We traced the frequency of occurrence of multirov spikes and studied the effect of this phenomenon on the productivity and the main quantitative characteristics of the studied plants. The article demonstrates the structure distinction of productivity for abnormal and normal ears. Experience was one-way vegetation, planted in triplicate, time of experiment - 2013 - 2015 years. The study revealed that the most frequent was the emergence of 1-4 additional spikelets per spike. Some quantitative characters had a slight deviation, these include the number of spiked ledges on the kernek, spike length and plant height. To a large extent we increased the characteristic values such as the number of grains per ear, number of spikelets per spike, number of grains onto the ledge, head weight and the weight of grains spike. We significantly reduced weight of 1000 grains. It was revealed that more localized spikes were mostly in the middle, the most productive part of the ear. As a result, changes have affected not only the quantitative characteristics related to the productivity of the ear, but also its architectonic whole

THE SHORTAGE OF WINTER WHEAT GRAIN CAUSED by P. triticina

abstract 1221608085 issue 122 pp. 1284 – 1293 31.10.2016 ru 484
The article studies the influence of the interaction of two technologies of plant protection: breeding- immunological and chemical. The studies were conducted on the varieties and lines of soft winter, durum wheat and triticale, established in Krasnodar research institute named after P. P. Lukyanenko, and also, on varieties of an alien and foreign selection. When considering the correlations in the group of genotypes, forming a necrotic type of reaction to the introduction of the pathogen (the first group of varieties), the significant negative correlation (r - 0,76) between the change in the mass of 1000 grains and the number of unproductive stems formed by one plan was established. The model of the severity of brown rust pathogen in sparse crops of wheat has been collaborated. According to the model, the development of the pathogen in the tissues of the leaves of the host plant leads initially to a change in the relations of the productive and unproductive stems. The change of these parameters significantly affects on the variability of indicators such as the mass of grains from one ear, number of grains per ear and 1000 grain weight. Negligible volatility of weight for 1000 grains suggests that the major losses of productivity in the flowering stage are due to abortive flowers. This model can explain the increase in the mass of 1000 grains in some varieties for tolerance change experiments with the defeat of plants of P. Triticina on micro-plots

WINTER WHEAT PRODUCTIVITY ON THE LEACHED BLACK HUMUS IN THE CONDITIONS OF THE WESTERN PRE-CAUCASIAN REGION

abstract 1251701049 issue 125 pp. 724 – 737 31.01.2017 ru 484
The reaction of winter wheat cultivar ‘Antonina’ on the level of fertility and doses of fertilizers on crop productivity was studied. Investigations are carried out in multivariate 11 –course crop and grain-grass rotation stationary: factor ‘A’- the fertility of the soil; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil cultivation: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. On the basis of proven researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased and nitrogen - up to 140 kg per hectare. The increase in yield is due the rise of the quantity of grains per ear and weight of grain per ear
