“…1-4). A. faecalis (BTCP01), initially discovered in feces, has been isolated from various environments, demonstrating its potential as a plant growth-promoting bacteria (PGPB) [48][49][50][51][52][53][54]. Our findings indicated that BTCP01 promoted rice growth and yield through nitrogen fixation (detected by nifH gene) and IAA production (detected by ipdC gene).…”

Endophytic bacteria, recognized as eco-friendly biofertilizers, have demonstrated the potential to enhance crop growth and yield. While the plant growth-promoting effects of endophytic bacteria have been extensively studied, the impact of weed endophytes remains less explored. In this study, we aimed to isolate endophytic bacteria from native weeds and assess their plant growth-promoting abilities in rice under varying chemical fertilization. The evaluation encompassed measurements of mineral phosphate and potash solubilization, as well as indole-3-acetic acid (IAA) production activity by the selected isolates. Two promising strains, tentatively identified asAlcaligenes faecalis(BTCP01) from Eleusine indica (Goose grass) andMetabacillus indicus(BTDR03) fromCynodon dactylon(Bermuda grass) based on 16S rRNA gene phylogeny, exhibited noteworthy phosphate and potassium solubilization activity, respectively. BTCP01 demonstrated superior phosphate solubilizing activity, while BTDR03 exhibited the highest potassium (K) solubilizing activity. Both isolates synthesized IAA in the presence of L-tryptophan, with the detection ofnifHandipdCgenes in their genomes. Application of isolates BTCP01 and BTDR03 through root dipping and spraying at the flowering stage significantly enhanced the agronomic performance of rice variety BRRI dhan29. Notably, combining both strains with 50% of recommended N, P, and K fertilizer doses led to a substantial increase in rice grain yields compared to control plants receiving 100% of recommended doses. Taken together, our results indicate that weed endophytic bacterial strains hold promise as biofertilizers, potentially reducing the dependency on chemical fertilizers by up to 50%, thereby fostering sustainable rice production.

“…A notable discovery in our study was the isolation of diazotrophic A. faecalis bacterium (BTCP01) from Goose grass (Eleusine indica), a native rice weed, which remarkably increased rice growth and yield with a 50% reduction in major chemical fertilizers (Table 1 and Figs 1-4). A. faecalis (BTCP01), initially discovered in feces, has been isolated from various environments, demonstrating its potential as a plant growth-promoting bacteria (PGPB) [48][49][50][51][52][53][54]. Our study revealed that BTCP01 enhances rice growth and yield by facilitating nitrogen fixation (as indicated by the presence of the nifH gene) and producing indole-3-acetic acid (IAA, detected via the ipdC gene).…”

Application of isolates BTCP01 and BTDR03 through root dipping and spraying at the flowering stage significantly enhanced the agronomic performance of rice variety CV. BRRI dhan29. Notably, combining both strains with 50% of recommended N, P, and K fertilizer doses led to a substantial increase in rice grain yields compared to control plants receiving 100% of recommended doses.
