Summary of Biostimulant – Synergistic Effect of a Plant-Derived Protein Hydrolysate and Arbuscular Mycorrhizal Fungi on Eggplant Grown in Open Fields: A Two-Year Study. Biostimulant : Synergistic Effects on Eggplant are a natural approach to enhance growth, yield, and fruit quality while promoting sustainable farming. Plant protein hydrolysates (PHs) and arbuscular mycorrhizal fungi (AM) are natural biostimulants that improve plant performance and reduce environmental impact. Combining microbial and non-microbial biostimulants produces synergistic benefits beyond their individual effects, making them highly effective for open-field eggplant cultivation.
Biostimulant Synergy for Boosting Eggplant Yield
A two-year study on “Birgah” F1 eggplant tested PH (“Trainer”) application and AM (R. irregularis) inoculation. Treated plants showed higher total and marketable yields, larger fruits, and more marketable fruits than untreated plants. These results demonstrate that combining PH and AM enhances eggplant productivity under field conditions.
Biostimulant Synergy for Improving Eggplant Fruit Quality
The combination of PH and AM improved fruit quality traits. Soluble solids, chlorogenic acid, total anthocyanins, potassium, and magnesium levels increased, while glycoalkaloid content and fruit browning potential decreased. These improvements enhance both the nutritional value and marketability of the fruits.
Biostimulant Role in Enhancing Nitrogen Use Efficiency
Biostimulants improved nitrogen uptake and utilization, reducing the need for synthetic fertilizers. Better nutrient management helps farmers maintain high yields and fruit quality while minimizing environmental impact.
Biostimulant Benefits under Environmental Variations
Seasonal differences, particularly maximum temperatures, influenced yield and fruit quality. PH and AM applications helped maintain consistent plant performance across varying climatic conditions, highlighting the practical benefits of biostimulants in eggplant cultivation.
Conclusion: Applying PH and AM together provides clear biostimulant : synergistic effects on eggplant, improving yield, fruit quality, and nitrogen efficiency, making them a sustainable and effective solution for modern eggplant farming.
