Summary
This research shows how combining beneficial soil fungi with an eco-friendly mulching technique can significantly improve lettuce-like vegetable growth. The study found that when these two approaches are used together, plants grow better by more efficiently using nutrients and maintaining optimal hormone levels. This has important real-world implications:
• Provides farmers with a sustainable way to increase crop yields without relying on chemical fertilizers
• Helps reduce agricultural plastic waste by using biodegradable mulching materials
• Demonstrates how natural biological partnerships can improve food production
• Offers solutions for growing food more efficiently in Mediterranean climates
• Shows potential for reducing water usage in agriculture while maintaining crop productivity
Background
Escarole is an important vegetable crop used in ready-to-eat salads, with increasing worldwide demand. Environmental sustainability concerns and growing food demand have led to interest in modern agricultural technologies like arbuscular mycorrhizal fungi (AMF) and mulching techniques to improve crop productivity. While both AMF inoculation and mulching separately show benefits for plant growth, their potential synergistic interaction has not been previously studied.
Objective
To investigate the interaction between hydromulching and AMF inoculation on escarole plant growth and productivity, and understand the underlying mechanisms related to nutrient uptake efficiency and hormonal regulation.
Results
AMF inoculation and mulching treatments, particularly their combination, significantly increased plant growth parameters including fresh weight and leaf area. The growth improvement was associated with enhanced nitrogen and phosphorous use efficiency and regulation of plant hormones. Both hydromulching and AMF increased active gibberellins and cytokinins, which positively correlated with growth parameters. The ethylene precursor ACC and abscisic acid decreased in AMF-inoculated plants, especially under hydromulching treatment.
Conclusion
The study demonstrates a positive synergistic interaction between AMF inoculation and hydromulching that enhances escarole plant growth through improved nutrient use efficiency and optimized hormonal balance. This combination represents a sustainable strategy to improve horticultural crop production, particularly relevant for food security in Mediterranean growing regions.
