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 article presents long-term studies of afforestation on
the Taman Peninsula. The directions of improving the
ecology of the peninsula are considered by increasing
the total biomass of the biogeocenosis of the given
region by creating forest plantations, increase of forest
cover and involvement of non-generating land in the
economic circulation. Practical agro-forest-meliorative
aspects of development of a specific category of nonproducing
lands are presented. The basic agrotechnical
methods are recommended at creation of forest
plantations. The analysis of the state of forest plantations
on the unique site of the Taman Peninsula is given - it is
a tract of Sad Yakhno
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
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
The article presents results of the studies that
obtained because of the long-term experience of the
Department of Agricultural Chemistry of Kuban
State Agrarian University. We have found the
optimal dose of micronutrients at different levels of
mineral nutrition, to achieve maximum yield of
green mass of alfalfa quality. We have calculated the
dynamics of the accumulation of nutrients in plants
throughout the growing season
The article considers the current state of production
of grain crops in the Republic of Sakha (Yakutia).
The analysis of gross collection, structural shifts,
sowing area and yield of grain crops over the past
five years is being carried out. Also, the application
of mineral and organic fertilizers to crops of cereals
is being investigated, since their application is of
great importance for obtaining high and stable
harvests of grain crops. Based on the results of the
analysis, conclusions were drawn and ways of
development of grain production in the republic were
outlined
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
Remineralization of leached chernozem was carried
out by applying such rocks as loess-like loam, shell
limestone, apatite phosphogypsum. We have
revealed that the introduction of species didn’t
change substantially the content of boron during the
growing season. We have also displayed the seasonal
dynamics of macro variants of the experiment and
the increase in the content of food items in the phase
of active growth of winter wheat. Seasonal dynamics
of trace elements is expressed, but can not be
expressed with certain regularity
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
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
