ABSTRACT

The field study was carried out in An Phu town, An Giang province, Vietnam during Summer-Autumn crop of 2023. The field experiment was carried out by eight treatments and four replications. Eight treatments consisted of two factors: (i) Enterobacter asburiae (EA) (inoculum and no inoculum); (ii) irrigation water (River and deep well water). The results of the study showed that EA inoculum and river water irrigation remarkably increased agronomic and yield traits such as height, branches, biomass number and weight of nodules and fill pods of peanut. Furthermore, EA inoculum combined with irrigating river water significantly increased peanut yield and reduced arsenic (As) uptake of peanut stems and seeds.  Enterobacter asburiae inoculation was higher than no EA inoculation by 19.7%. River irrigation had the higher fresh peanut yield (6.17 t/ ha) compared to irrigation of deep well water (3.10 t/ ha). The interaction between bacteria inoculation and irrigated water types was not significant differences at 5% level. Furthermore, The As accumulation of peanut stems and seeds of EA inoculation was lower than 12.3% in stems and 4.06% in seeds. Irrigating river water for peanuts, which absorbed lower As toxicology of stems and seeds than irrigating deep well water from 16.5% (stems) and 39.7% (seeds).  Enterobacter asburiae may be a potential genus to product biological fertilizers in the future.
