The article provides an overview of the results of the research of non-root treatment of bushes with activated water with the features of BAS. We have found that activated water, charged with the "Akvator" device through the BAS matrix has the property of impact on plant and the efficiency exceeds impact of BAS solutions themselves

In the article we present questions of digital process control of heated air for drying seeds; it is shown that the change in the load of the heat source slightly changes the dynamics of the system for stabilizing the temperature of hot air, making it almost invariant with respect to perturbations. It is proved that the use of digital controller with dual differentiation significantly improves ...

The developed mathematical model of the machine and tractor unit with the elastically damping mechanism in transmission of a tractor is given in the article. The analysis of mathematical model of the arable unit on the basis of a tractor with EDM in transmission showed that the MTU mathematical model can be considered as working

This article discusses the ways of reducing the financial, economic and social risks on the basis of an accurate prediction. We study the importance of natural time series of winter wheat yield, minimum winter, winter-spring daily temperatures. The feature of the time series of this class is disobeying a normal distribution, there is no visible trend

SUBJECT: long-term memory; hurst exponent; r/s-analysis of natural time series; agricultural sector; empirical distribution function

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

SUBJECT: regeneration ability of cuttings; grape; biotest; energy of seed propagation; inhibitors

The newest wine grape variety Eftihiya with aromatic pink colored skin (in Greek the name means “happi-ness”) was breed with hybridization at the Athens In-stitute of Viticulture by P. Zamanidi, L. Troshin and P. Radchevskiy in 2005 by crossing the Greek varieties and Malaguzya with Eurasian Traminer pink. Dura-tion of production period from bud burst to harvest 146-155 days. Yields are very h ...
