Indole-3-acetic acid (IAA) is a potent plant hormone classified as a nitrogen fertilizer. As a main regulator of plant growth, it plays an important role in varied physiological processes, comprising root initiation, cell elongation, and fruit development. Available as a quick-release powder with 97% purity, it is extensively applied in agriculture for stimulating root formation, increasing fruit set, and enhancing overall plant growth. Its classification as a nitrogen fertilizer underscores its significance in optimizing nutrient utilization in crops. IAA is instrumental in promoting robust plant growth and improving crop yields, making it a valuable tool for sustainable agricultural practices.
