In the course of research the impact of polymeric pellicle-forming growth regulators (PGR) on the growth and development of rice plants while cultivated in conditions of salinity has been studied. It was ascertained that preseeding PGR treatment of seeds at the rate of 10 liters of solution for 1 (one) ton of seeds boosts germination energy, germinating ability of seeds, sprouts, length gets extended and weight enlarged. PGR lead to increase of electrochemical gradient on the membranes of chloroplasts, tilacoids and acceleration of electrons transport between I and II photo systems. PGR diminish toxicity of salinity which is fixed in parameters measured in experiments that are close to the control values. PGR application improves parameters of the structure of rice crop cultivated in conditions of salinity.
Influence of level of soil fertility, norm of fertilizers, systems of plant protection and a way of basic soil cultivation on accumulation and a ratio of chlorophylls in leaves of a winter wheat Nota during spring-and-summer vegetation is shown.

The extensive overview of the currently used herbicides antidotes of agricultural crops is reviewed in this article. The most important results are discussed and the technology of combined application is described
Influence of level of soil fertility, norm of fertilizers, systems of plants protection and a way of basic soil cultivation on accumulation of chlorophylls in leaves and on an index of a sheet surface of crop of Note winter wheat in a heading-flowering phase is examined.
The article discusses the most important results of applying the composition of the furolan and methionin witch have properties of abiogenic elicitors against the fusarium
In the article, we have made an attempt to develop and calculate a model of humus content estimation in the black leached soil according to remote sensing of the ground. We have presented the model which has a number of restrictions for its continuous use when carrying out soil environmental monitoring of land grounds. It is established, that for calculation of similar model it is necessary to perform the cameral works including selection and the preliminary analysis of fields, including using of contemporary records of Remote sensing of the ground for definition of sampling points, to carry out an assessment of space photo shooting and sampling of soils in optimum terms with the maximum synchronism (cameral work and soil and agrochemical inspection), to make the analysis of the selected samples of soils for humus content with traditional methods, and finally to calculate regression models with use of data of the carried-out space shooting and the agrochemical analysis of soil samples
The most important results of applying the composition of the matter which has antidote functions furolan and methionin against the herbiside 2,4-D are reviewed in this article
Species composition and abundance of soil algal flora
were studied in the Central zone of the Krasnodar region
on crops of crops cultivated by various technologies. In
the algal flora of the studied area, 48 species of soil algae
and cyanobacteria from 28 genera and 18 families, 7
classes and 4 divisions were identified. The largest and
numerous in number of species are the departments:
Cyanophyta and Chlorophyta. Extensive delivery:
Oscillatoria, Gloeocapsa. They account for 22 % of the
total number of species. A negative effect of herbicides on
number and species composition of soil algae was noted.
In all variants of their application there was no form of
Klebsormidium flaccidum (Kützing). The number of
species of Chlorella vulgaris Beyer. was low,
Botrydiopsis arhiza Borzi. It is believed that these species
of algae can be used as bioindicators. The positive effect
of mineral fertilizers and the aftereffect of introducing
organic matter on the soil algal flora have been
established. In these variants the deleterious effect of
herbicides was reduced. According to the calculated
regression equations, the applied mineral fertilizers to a
greater extent weakened the negative effect of herbicides
on the total number of populations than the aftereffect of
introduced organics
The article studies species composition and abundance of soil algae under hybrid Krasnodar 292 AMB cultivated with various technologies. 7 species of cyanobacteria and 11 soil algae were revealed. It was revealed that the highest total amount of algae was observed in variants of environmentally acceptable and intensive technology, which is associated with the positive effect of mineral fertilizers and the consequent application of organic matter on soil algal flora. However, in these variants a decrease was observed both in the number of species and in the abundance of green and yellow-green algae. The species Botrydiopsis arhiza Borzi was absent or found in insignificant amounts. The species composition was less diverse, which can be attributed to the negative effect of the herbicide used in these technologies. The method of tillage had practically no effect on green, yellow-green and diatoms. An increase in the intensity of soil cultivation had a significant negative effect on both the species composition and the number of cyanobacteria
