Water regime dynamics of the Imrus apple cultivar grown on dwarf and semi dwarf intermediate stocks was studied during vegetation. As a result of the investigations the highest total water contents of the variety-rootstock combinations was noted at the beginning of vegetation and then, as the age of leaves increased and the water-supply-level of plants decreased, the contents of the total and available water were reduced. The increase of bound water was observed during more droughty periods. As a result of leaf water loss and the following water saturation, Imrus grown on small-sized intermediate stocks showed the moderate level of drought resistance.

This article presents the results obtained on the influence of the biostimulator Microzim-2 in the soil and climatic conditions of the Bukhara oasis. It has been established that the use of the biostimulator Microzim-2 has a positive effect on the growth and development of cotton and helps to increase soil fertility in conditions of water deficiency and soil salinity.

The article presents the results obtained during the research. It was established that water deficiency negatively affects all life processes of the living world, while there was mainly an imbalance of water exchange, espe-cially in cotton and wheat plants. The negative effect of soil salinity on physio-logical and biochemical and adaptive properties of plants. The results ob-tained can be used in the educational process for students and masters.
