There were some results of the agricultural touch influence and dose of chemical fertilizers on the productivity of grape and its quality shown in this article
Experiment planning is presented in the article on preseeding processing of seeds by variation electromagnetic field of industrial frequency. The results of preliminary laboratory researches are given
There were determined the close correlation dependence
between the energy of propagation of wheat seeds sunk
in water in which the grape cuttings were rooted on one
side and the rooting and output of cuttings with three
roots and more on other side by the authors. There were
the equations of regression for prognosis of rooting and
output of cuttings with three roots and more
The article provides the data of the researches of studying of samples of haricots varieties and selection the highest yield for the conditions of the Azov zone of the Rostov region, and also their economic assessment
The article presents materials on comparative study of the nutritional value of chickpeas and peas which are widespread in the arid zone of the Southern Urals. The scheme of the scientific and economic experiments involved the assessment of yield formation of chickpeas and peas during the vegetation. The study showed that different varieties of chickpea and pea have considerable difference in the content of nutrients. The amount of crude protein in the pea grain ranged from 25.1 to 26.8%, and chickpea – 21.7 - 22.9%. With regard to the fat, its highest concentration was in chickpea grain - 3.63%, on average, which is 1.16% higher than on average in the pea grain. The chemical composition of the pea and chickpea grain of different varieties points to differences in their composition and homogeneity within the culture. Basing on the study, we recommend to sow chickpea and pea grain in the middle of May to obtain the highest yield, this, in turn, has a positive effect on the nutritional value of the crops. When selecting plants for cultivation in the conditions of the Southern Urals, it is preferable to choose the variety of Madonna pea, which has a higher potential for yield than the chickpea variety Krasnokutsky-123. It has been experimentally found that chickpea grain has better moisture-retaining power in a bound condition during the vegetation period as compared to the relevant characteristics of pea grain, which is a positive drought-resistant value of crop. In structural elements of the harvest the peas showed the trend of the highest rates in comparison with the corresponding elements in chickpeas
The article presents the results of the research devoted
to the poultry feeding with pumpkin cake and pumpkin

This article discusses the adaptive nature of the correlations between the elements and sub-elements of the productivity of main spike of the F1, and F2 hybrids, constant breeding lines (F3, F4) and parental varieties. We have shown the possibility to determine the individual components of spike productivity with a selective advantage in the selection of winter wheat on the adaptability and efficiency in the conditions of the region
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 â„–
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
As the result of 4-year researches there were studied the main economic characteristics of the apple-tree varieties Retina, Renora, Revena Reanda, Remo and Piccolo. The varieties that were positive selected in fruit crop productivity, quality and keeping capacity were recommended for wide productive experiments. There was shown the possibility of use of studied alien varieties as pollinators
