Abstract

Rice production in the Mekong Delta mainly uses chemical fertilizers, which increases the production cost and decreases the soil fertile. This research surveyed the effect of 4 endophytic bacterial strains NS01, NS08, NS17 and NS25 with their ability of NH4+ collected and phosphorus solution on the growth of rice varieties IR50404, OM4900 và OM5451 at their vegetative phase. It shows that IR50404 rice variety combined with NS25 bacterial strain get the best results regarding chlorophyll content, plant height, root length, number of root and dried matter weight. On analyzing the 16S rDNA region, NS25 strain is found to belong to Bacillus genus.
