Evaluation and SEM analysis of plant endophytic bacteria Isolated from rain tree Samanea saman (Jacq) Merr on the growth performance of foxtail millet Setaria italica
Abstract
Due to overpopulation, there is an increasing demand for more food crops and nutrients. Consequently, the world requires a greater production of grains and millets, as millets are a highly nutritious food source. To meet the nutritional needs we are cultivating larger quantities of millet Foxtail Millet Setaria italic. Recognizing the harmful effects of chemical fertilizers on human health, there is a pressing need to shift towards bio-fertilizers. This study investigated the plant growth promotion activities of two endophytes (SRP1 and SRP2) isolated from Pods of Rain tree (Samanea saman (Jacq) Merr). Comprehensive analysis revealed that SRP1 and SRP2 positively influenced various parameters associated with enhanced plant growth. SRP1 and SRP2 exhibited significant potential as a plant growth-promoting Endophytes (PGPE) enhancement in Foxtail millet plants, efficacy testing under field conditions, they are essential to elucidate the role of PGPE as biofertilizers that confer beneficial effects on host plant growth and development.
