Foliar NPK Fertilizer Boosts Rice Yield and Quality in Egypt.
Foliar application of NPK or urea on rice plants can increase grain yield and quality. The study used NPK (20:20:20) and urea as fertilizers, applying them at specific rates. Results showed that applying NPK or nitrogen alone twice can improve rice productivity. The best results were seen with 123.75 kg N ha-1 combined with foliar NPK application or 2% nitrogen twice. This approach led to higher grain yield, better grain quality, and improved economic returns.
