Eco-efficient microbial inoculant solution for basil production under drought stress
Biofertilizer technology using microbial inoculants to reduce mineral fertilizer requirements in basil crops while improving drought tolerance, lowering production costs, and decreasing environmental impact.
Overview
This solution leverages beneficial microorganisms to improve the sustainability and productivity of basil cultivation. By applying specific microbial inoculants, growers can reduce dependence on nitrogen and phosphate fertilizers, lower input costs, and enhance plant resilience to drought stress caused by climate variability. The technology addresses key challenges in basil production, including excessive nitrogen fertilizer use, soil erosion, water pollution, and limited understanding of phosphate nutrition management. It offers an eco-efficient pathway for producers seeking to maintain yields while minimizing environmental footprint.
Technical specifications
Microbial strains under investigation:
- Azospirillum brasilense D7
- Rhizobium sp. B02
- Herbaspirillum sp. AP21
- Bacillus sp. XT14
- Two microorganisms contained in the Monibac biofertilizer
Key features:
- Plant growth promotion validated in cotton, maize, rice, kikuyu grass, raygrass, and red clover intercropping systems
- Potential to reduce nitrogen and phosphate fertilizer doses
- Mitigation of drought and saline stress effects on crops
- Prototype alginate microcapsule formulation for strain delivery and co-inoculation
- Randomized experimental design evaluating fertilization doses and strain combinations
Technology readiness level
The technology is at the experimental validation stage. Prior studies in other crops have demonstrated the plant growth-promoting potential of the candidate strains. Current and future validation activities include controlled trials testing fertilization doses and microbial combinations, stress-response evaluations with and without drought conditions, and on-farm validation at producing farms using prototype alginate microcapsule formulations. The reduced fertilization rate will be defined based on trial outcomes, with co-inoculated strains advancing toward farm-level validation.
