This research investigated how certain beneficial fungi can help protect plants and promote their growth even under stressful salty conditions. The researchers found that three different strains of Trichoderma fungi could effectively protect melon plants from disease and enhance their growth despite high salt levels in the soil. This has important real-world implications: • Reduces the need for chemical pesticides and fertilizers in agriculture • Helps crops grow better in areas affected by soil salinity • Provides more sustainable and environmentally-friendly farming solutions • Could improve food production in regions with poor soil conditions • Demonstrates natural alternatives to harmful agricultural chemicals
