Abstract

The utilization of locally available organic materials as liquid organic fertilizer (LOF) represents an eco-friendly biofertilizer alternative that supports sustainable agriculture and environmentally responsible farming practices. This community service program aimed to improve farmers’ knowledge and technical skills in producing and applying liquid organic fertilizer derived from local organic resources, including moringa leaves (Moringa oleifera), aged coconut water waste, a weed-based biostimulant (BIOSAKA), and photosynthetic bacteria (PSB)to promote plant growth and enhance maize production. The program was implemented using a two-way interactive learning approach that combined educational sessions and hands-on practice on the utilization of organic liquid fertilizer (LOF) in maize cultivation. The program's effectiveness was primarily evaluated based on farmers’ level of understanding after the training activities. Evaluation was conducted using a structured questionnaire administered at the end of the program, which assessed participants’ comprehension of LOF materials, production principles, and application methods. The collected responses were used to determine changes in participants’ knowledge and overall learning outcomes resulting from the program. The evaluation results revealed clear quantitative improvements in farmers’ knowledge, technical understanding, and readiness to adopt locally derived organic fertilizers. Prior to the intervention, only 10–30% of participants were familiar with the concepts, raw materials, and production methods of liquid organic fertilizer (LOF), photosynthetic bacteria (PSB), and BIOSAKA. Post-training assessments showed a substantial increase, with 87–100% of farmers demonstrating an understanding of production procedures and application methods. In addition, 85% of participants recognized the functional roles of PSB, LOF, and BIOSAKA in supporting maize growth and soil fertility, while 95% expressed willingness to apply these organic inputs in their future farming practices. These quantitative shifts indicate that the community-based training effectively strengthened farmers’ capacity and confidence to utilize locally sourced organic resources independently.

Abstract

Background: The intensive and prolonged use of synthetic fungicides, particularly mancozeb, exerts selective pressure on non-target microbial communities, potentially promoting the emergence of tolerant populations. Therefore, biocontrol agents that remain effective under such chemical stress are needed. Objective: This study aimed to evaluate the tolerance responses of Streptomyces xiangtanensis NBSP3F and Trichoderma asperellum G-4274-1 to mancozeb exposure across a gradient of concentrations. Methods: The experiment was conducted in vitro using a poisoned food technique at six concentrations (0%, 1%, 2%, 3%, 4%, and 5%) with six replications. Tolerance of S. xiangtanensis was assessed qualitatively based on colony growth, while T. asperellum was quantitatively evaluated using mycelial radial growth and growth inhibition metrics. Results: Results showed a concentration-dependent suppression of growth in both isolates. S. xiangtanensis maintained complete growth (100%) at 0–1% concentrations, decreased to 75% at 2–3%, 50% at 4%, and 25% at 5%. T. asperellum exhibited stable growth (90–100%) at 0–2%, moderate reduction (70–72.5%) at 3–4%, and a decline to 45% at 5%. Comparatively, T. asperellum showed higher physiological resilience than S. xiangtanensis under intermediate to high fungicide stress, though both isolates had reduced adaptability at the highest concentration. Conclusions: These findings indicate species-specific differences in adaptive capacity to multisite fungicidal stress, likely due to variation in metabolic flexibility and stress-response mechanisms. Collectively, both isolates demonstrate strong potential as multifunctional biocontrol agents, integrating pathogen suppression, plant growth promotion, and possible roles in pesticide-tolerant biodegradation, offering promising implications for sustainable agroecosystem management.
