The experiments were carried out in five variants, in different values of the integrated density of plants and lasted 89 days. As a feed, specially prepared bio fertilizer was used and added with the calculation of 1 kg per 1 m2 of area. In the corresponding control variants, bio fertilizer was not used. Analysis of the experimental results showed that the feeding regime made it possible to obtain a maximum yield at higher integral density. At the same time, the increase in the weight of green mass when using bio fertilizers was about 36%.展开更多

During the study, changes in the physical properties of water, land drainage, groundwater level, mineralization, soil salinity of this territory have been investigated as well. Studies show that in the current territory elevated levels of ground water in drainage and irrigation networks, revealed that their mineralization and the amount of salts in the soil were under bad condition. On the basis on studies measurements for soils state in Mugan-Salyan massif have been presented.展开更多
