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
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
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
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
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 was shown the possibility of assessment of hybrid apple-tree posterity on relation to the drought with the help of mathematical modeling. There was worked out the mathematical model of prognosis character on assessment of apple-tree genotypes to the given stressor. There were offered ways of optimization of hybrid posterity selection conducting in modern selection programs
The application of bioactive preparations during taking root of green cuttings conifers family of Cupressaceae has been described in this article. Longstanding experiments of growing planting stock with open and closed roots have been realized. Increase of taking
root, apical growth and development of root’s system by positive influence of preparations has been shown
The article presents the results of diagnosis of soybean plants with sulfur, molybdenum and boron in a Western Ciscaucasia on leached chernozem (black soil). The soil testing has shown that the availability of sulfur in the experimental plots is low (2,10-7,02 mg / kg), molybdenum - average (0,20-0,28 mg / kg), boron - low to high (0, 22-0,63 mg / kg). The sulfur content was optimal in 2013 (2309 mg / kg), molybdenum - 2013 and 2014 (1.11 and 0.94 mg / kg) and the boron content was high (65,2-94, 1 mg / kg) in soybean plants. The soybean plants needed sulfur fertilizer in 2012 and 2014, molybdenum - in 2014, and boron fertilizers are not needed, according to the functional diagnosis. The results of various methods of diagnosis coincided with the response of soybean plants for foliar application: sulfur fertilizer increases the yield in 2012 and 2014 by 7.1 and 8.9 %, molybdenum also in 2012 and 2014 - by 6.0 and 10.0 %. Boron fertilizers in 2014 increased soybean yields (17.1%), despite the lack of need for soybean plants in Bor. So, the method of functional diagnostics is more accurate than chemical soil and plant diagnostics
In the article there were presented the results of cultivation of an apple-tree garden with application of growth stimulators. Positive action of Buton and Mival-Agro preparations on grades of all terms of maturing is noted
The article discusses the development of piglets in utero using irradiation lamps IK -250 and BUV – 15
