“…The study by Khalid et al [23] supports these findings by demonstrating that PGPR can enhance plant nutrient uptake efficiency, including iron. Increasing iron availability gives plants better access to the nutrients needed for chlorophyll synthesis, energy metabolism, and other physiological functions, which positively impact plant growth and productivity [1,2,10,24].…”

Plant Growth-Promoting Rhizobacteria (PGPR) plays a crucial role in enhancing plant health, while Burkholderia sp. has been identified and has potential as a promising PGPR for maize plants. Recognizing the essential role of PGPR in plant health, this study explores how L-TRP addition might improve PGPR performance for better plant growth. Employing a completely randomized design, the study assesses the effects of Burkholderia sp. as PGPR on maize growth across three treatment groups: PGPR with L-TRP, PGPR without L-TRP, and a control group. The evaluation focuses on plant growth metrics, plant hormone production (auxin and gibberellin), and siderophore activity to gauge plant iron availability. Statistical analysis highlights that L-TRP supplementation notably increases auxin production in the PGPR + L-TRP group, surpassing the PGPR without L-TRP and control groups. Although both PGPR treatments elevate gibberellin levels compared to the control, auxin increase is the most significant outcome, indicating no substantial difference in gibberellin levels between the two PGPR groups. Enhanced siderophore production suggests improved iron assimilation for plants. The findings demonstrate that L-TRP supplementation with PGPR, particularly Burkholderia sp., effectively boosts maize growth, primarily through increased auxin and siderophore production. This combination presents a promising strategy for augmenting agricultural yields, especially for maize productivity, by leveraging the synergistic effects of soil microbes and nutrient supplementation.

The improvement of crop productivity has become a primary focus in modern agriculture, with ongoing research aimed at identifying effective strategies. In this context, the study aims to explore the potential of L-tryptophan (L-TRP) supplementation in enhancing the effectiveness of Plant Growth-Promoting Rhizobacteria (PGPR) Burkholderia sp. in promoting the growth of maize plants. The research background elucidates the crucial role of PGPR in enhancing plant health, while Burkholderia sp. has been identified as a promising PGPR for maize plants. However, the potential of adding L-TRP to enhance the performance of PGPR in the context of plant growth has not been fully explored. The research methodology involves the rejuvenation of Burkholderia sp. bacterial cultures followed by testing the influence of PGPR on maize plant growth in controlled pot experiments. Three treatment groups were formed: PGPR + L-TRP, PGPR without L-TRP, and a control group. Observations were made on plant growth and the concentration of plant hormones such as auxin and gibberellin, as well as siderophore activity. Statistical analysis was used to evaluate differences between treatment groups. The research findings indicate that L-TRP supplementation in PGPR Burkholderia sp. significantly increases plant auxin production. The PGPR + L-TRP treatment resulted in higher auxin concentrations compared to the PGPR without L-TRP treatment and the control group. Additionally, both PGPR treatments showed higher gibberellin concentrations than the control, although there was no significant difference between the two PGPR treatments. The findings suggest that PGPR, especially with L-TRP supplementation, also yield higher siderophore concentrations, indicating increased iron availability for plants. The novelty of this research lies in the revelation that L-TRP supplementation can enhance auxin production and siderophore availability by PGPR, providing important insights into the interaction between soil microbes and their host plants. The conclusion drawn from this study is that the combination of PGPR with L-TRP supplementation can be an effective strategy for enhancing agricultural yields, particularly in increasing maize crop productivity. The practical implications include the potential for developing optimized PGPR formulations with L-TRP supplementation to improve agricultural yields sustainably. The significance of these findings lies in uncovering new potential for enhancing crop productivity through the use of a combination of soil microbes and nutrient supplementation, laying the foundation for the development of more effective and environmentally friendly microbial-based agricultural strategies, focusing on the integration of PGPR with L-TRP supplementation in agricultural systems. This could provide innovative solutions for enhancing agricultural productivity sustainably while reducing reliance on expensive and potentially environmentally damaging chemical inputs.
