- Intervention effect Exogenous commercial IAA at 50 ppm improved the fresh weight of onion bulbs.
- Intervention effect Exogenous commercial IAA at 50 ppm increased the antioxidant capacity of the onion plant.
- Intervention effect Applying the fermented solid to lettuce under water stress significantly improved physical parameters (biomass and leaf area).
- Intervention effect Applying the fermented solid to lettuce under water stress significantly improved chemical parameters (chlorophylls and carotenoids).
- Intervention effect In lettuce seedling trials the fermented solid increased germination rate, root development and pigment content.
- Intervention effect The fermented solid increased lettuce seedling chlorophylls by up to 214% relative to the control.
- Observation Trichoderma viride in tray bioreactors reached optimal IAA concentrations of 112.6 ug/g.
- Intervention effect Fermented-solid treatments with high (FS-H) and medium (FS-M) IAA concentration promoted greater biomass, root length and shoot length in lettuce seedlings than the control.
- Intervention effect FS-H and FS-M treatments promoted greater vigor and chlorophyll content in lettuce seedlings than the control.
- Intervention effect FS-H and FS-M treatments promoted greater nutrient uptake (K, Ca, Mg, P and S) in lettuce seedlings than the control.
- Intervention effect Pellets increased lettuce biomass, chlorophyll content and phenolic compounds.
- Intervention effect Pellets increased lettuce antioxidant activity and foliar nutrients (N, P, K, Ca and Mg).
- Intervention effect Pellets increased soil enzymatic (phosphatase) activity in the lettuce crop.
