The article presents the results of three-year researches on the study of indexes of ripening of grafts-coefficient and conditional coefficient of ripening at 9 resistant table and technical varieties of grapes and indexes of their root-formation ability when rooting in water. There was cited the analysis of presence, direction and degree of correlative connections between two studied indexes
There were presented the results of researches on study of influence of processing of grape grafts of resistant table variety Moldova by impulsive electromagnetic field on their shoot- and root-formation ability

In this article the influence of agrotechnologies of cultivation of field cultures on soil indicators and distribu-tion of heavy metals on the horizons of the black leached soil is considered. Regularities of distribution of gross and mobile forms of manganese, zinc, lead, cobalt, copper and cadmium on the genetic horizons of the black leached soil of the Azov-Kuban lowland are revealed
In the main collectors in the North-West Caspian we have found the concentration of priority chemical elements: in water - Zn, Cu, Mn, Co, B, Mo, Cr, Ni, Pb; in sediments - Zn, Cu, Mn, Cr, Ni, Pb. It was found that a common and characteristic feature of drainage water is a low concentration of these elements investigated (except Mn, B, Pb). In the bottom sediments collectors content of gross forms of Zn, Cu, Mn, Ni, Pb and mobile forms of Zn, Cu was below the MRL and the content of the gross forms of Cr and Mn mobile forms was a little higher
