The effect of halophilic microorganisms BACILLUS SP. ПК-1 for growth and development of corns in irrigated saline soils of Turkestan region
AbstractThe study examined the effect of salt tolerant halophilic microorganisms isolated from irrigated salinesoils of the Turkestan region on the growth and development of corn crops. Our goal was to study theeffect of seed inoculation and foliar feeding of the strain Bacillus sp. ПК-1 for the growth and development of corn in irrigated saline soils of the Turkestan region. Cultivation of the strain Bacillus sp. ПК-1was carried out on a medium MPA (meat peptonic agar) (50.0 g/l NaCl, pH 7.1) circular rocking 220 rpmat a temperature of 280C for 72 hours. It was established that pre-sowing treatment of corn seeds withculture liquid Bacillus sp. ПК-1 increases germination by 15-35 %. Double foliar feeding of maize plantsenhances the growth and development of plants twice, increases the biomass of roots by 50 %. Thus, ourresearch has shown that the strain Bacillus sp. ПК-1 may be promising for the creation of a new biological product based on native halophilic bacteria for seed inoculation and foliar feeding for the growth anddevelopment of maize in irrigated saline soils of Turkestan region.Key words: corn for grain, salt-resistant microorganisms, PGPR bacteria, Bacillus, growth-stimulatingactivity.
