Boron is an essential micronutrient for plants, and it plays a key role in many plant processes including cell division, cell wall formation, and seed development.
Rice is one of the most important crops in the world, and providing sufficient boron nutrition is critical to ensuring its high yield and quality.
Boron uptake by rice plants generally occurs through the roots, with the roots of young plants being more efficient at uptake than those of older plants.
Boron acquisition by rice plants can be enhanced through the use of amendments such as compost or manure.
Furthermore, grafting has been shown to improve boron uptake in some cases.
