FUNCTIONING OF SOYBEAN-RHIZOBIA SYMBIOSIS AFTER VARIOUS METHODS APPLYING TRACE ELEMENTS COMPLEX

Objective. Investigate the effect of inoculation soybean seeds with an active strain nodule bacteria Bradyrhizobium japonicum T21-2 and treatment seed or vegetative plants a complex trace elements Avatar-2 on functioning symbiotic apparatus grain productivity. Methods. Physiological, microbiological, gas chromatographic, vegetation experiment, statistical. Results. As result joint Avatar-2, inhibition nodulation activity nitrogen-fixing microorganisms in stage three true leaves was revealed comparison systems formed as standard rhizobia strain. In budding / beginning flowering bean formation roots this variant, number nodules exceeded corresponding figure plants, bacterized without use by 16.6 % 24.1 %, respectively. The combination feeding during did not have significant flowering. However, formation, 38 increase detected compared to grown from inoculated (without elements). Activation growth processes at all stages plant development when exposed bacterization different methods noted. Inoculation using microfertilizers, both separate cultivation technology treatments conditions resulted decrease content copper, zinc, iron nickel. It found that pre-sowing chelated nutrients caused weight per 17.8 non-inoculated growing fertilizer — 27.5 control. factors bacterial preparation element also had positive individual productivity evidenced 14.4 30.2 whose were treated only. Conclusion. intensification through microfertilizer highly has impact growth, creates reserve crop.
