Models of model trees in the manner of equations for calculation of the current increase of trees at radius in cedar, mixed fir and pine plantings are received. At calculation of the current increase at radius and height using the diameter of a tree on height bosom without cortex, age tree and average distance from nearest tree on radius is recommended.
In peach orchards of the Russian humid subtropics, leaf curl is the most dangerous and harmful disease. Due to the high degree of danger from the peach leaf curl, for the first time in this region the main task was to analyze peach leaf curl development on weather conditions. In order to solve the problem, it is proposed to apply a new innovative intellectual technology: automated system-cognitive analysis (ASK-analysis) and its software tools - the “Eidos” system. In order to build the model, based on our own observations and the experience of Russian and foreign colleagues, it was decided to use the following factors: the sum of temperatures above +4 ° C of the current year (for the period from January to April), the sum of temperatures above +4 ° C of the previous year (for the whole year), the sum of precipitation of the current year (for the period from January to April), the sum of precipitation of the previous year (for the whole year), the number of hours of infection (in the current year). It was established that such factors as the number of hours of infection, the sum of temperatures above +4 ° C in April and during the period from January to April, as well as the sum of precipitation in March and April, are the most important in the dynamics of peach leaf curl development and spread. High rates of leaf curl spread and development are caused by the number of hours of infection in the range of 1440 ... 2064 hours, as well as by low air temperatures in March and April (the sum of temperatures above +4 °C – 89,4-240,4° and 283,7-316,7°, respectively) and high air temperatures - in January and February (the sum of temperatures above +4 ° C – 155,3-259,6° and 243,5-280,1°, respectively)
Elements of the cultivation technology of winter wheat variety called ‘Antonina’ with the application of different backgrounds of soil fertility, norms of fertilizers, system of plant protection from weeds, pests and diseases were studied. The studies are conducted in a polyfactorial stationary experiment: factor A - soil fertility; factor B - system of fertilizers; factor C - plant protection system; factor D - methods of basic soil cultivation. In the experiment four models of soil fertility levels were studied: А0 - the initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of litter manure); А2 - increased (doses are doubled); when А3 - high (tripled). Based on the studies it has been established that to obtain a stable yield of winter wheat, an increased dose of mineral fertilizers should be used, which also ensures high grain quality indicators. The maximum yield increase of 37% was achieved on varieties in comparison with extensive technology. A significant increase of the protein content in the grain from 12.8 to 15.3% and gluten from 22.0 to 27.8% was found in the intensive technology - triple doses of fertilizers (NPK) and the use of integrated protection against diseases, pests and weeds. The introduction of high doses of mineral fertilizers contributes to the accumulation in the soil and grain of nitrogen, and also reduces the content of copper and zinc
The design procedure of a parity irrigated and dryland shares of farmland on various types of agrolandscapes, which develops from a recommended parity of environment formatting and environment destroying grounds, providing protection of soils from erosion and supporting their fertility at certain level is resulted in article
It has been proved, that by means of information technologies, it is possible to fix the wind erosion operatively, to determine the sizes of soil losses. The mathematical model of process of the wind erosion during the winter period is created
Decreasing of noise level depending on park plantings structure parameters is reviewed in this article. The connection between noise level and these parameters is shown. Equation allows calculating its decreasing at the stages of park designing and reconstruction is revealed
The method and results of forecasting of crops of agricultural crops in the Rostov region on reclamated lands are resulted. The method is based on use of dependence of crops of agricultural crops from agro meteorological factors. Results of calculation on planning crops of winter wheat at irrigation are shown
Rice blast caused by Pyricularia oryzae is a major disease affecting rice production grown in upland and wetland rice. Application of biotechnological approach to protect against the disease may be an alternative strategy to chemical control
Analysis of rice market in the country was conducted,
as well as assortment of rice products was studied. It is
shown that rice is the most popular grain in Russian
Federation and in percentage of cereal products in
shops they occupy 29% and in diet of Russian people
– 41%. It is found that in Russia round grain japonica
varieties are the most popular kind. It is mentioned
that for the last years consumer market demands
diversity of rice products, including long-grain and
exclusive varieties, imported from abroad. It is shown
that in big cities demand for such products has
increased from 5% to 15%. Analysis of milled rice
balance was conducted. It is found that volume of
milled rice in the domestic market of the country is
annually about 680-800 thousand tons exceeding the
average demand value by 54,8 to 172,3 thousand tons.
Promising breeding directions are observed for
increasing assortment of rice products in Russian
markets with a view to import substitution. It is
mentione that Russian breeders have developed group
of exclusive varieties: Rubin, Mars, Viola, Violetta,
Avstral, Ivushka, Natasha, Aromir etc. It is shown that
special purpose varieties currently occupy 3,5% of rice
acreage in the Krasnodar region and their cost is by
20-70% higher than that of traditional rice varieties. It
was found that for their implementation into
production and promotion on the consumer market we
need to develop agricultural techniques of cultivation
and seed production scheme in accordance with the
biological characteristics, conduct marketing
activities, promotion of a healthy diet
We have performed an analysis of the current state of
rice seed production in the Krasnodar region. It is
shown that over the last 10 years in Kuban a full
variety changing took place, which was caused by
State support of rice seed production on the federal
and the regional levels. Agricultural producers of the
Krasnodar region have completely stopped cultivation
of medium-ripening rice of Liman variety, increasing
acreage of new varieties such as Victoriya, Sonet,
Diamant, etc. which allowed to increase crop yield
from 47,1 centner/ha in 2006 to 63,0 centners/ha in
2015 and to improve the quality of commercial grain,
decreasing the content of red-grain forms average in
the Krasnodar region from 20,5% in 2006 to 1,8% in
2015. Legal basis of realization of state agrarian
policy in the field of seed production of agricultural
crops, including rice is reviewed, recent changes in
the legislation of the Krasnodar region concerning
seed production of agricultural crops are shown, as it
was reflected in the Law of the Krasnodar region №
3062-KZ dated 28.11.2014 "On the regulation of
certain relations in the field of seed production in the
Krasnodar region". Areas contributing to the
development of the rice seed production in the Kuban
region are identified for further conducting of variety
changing, introducing new high-yielding varieties into
production as well as varieties of special purpose for
import substitution
