Rice Nutrient Management and Key Growth Stages

Rice nitrogen, phosphorus, potassium and silicon needs across tillering, booting and grain-filling.

FAQ

Q: When does rice need the most nitrogen?

The tillering and panicle-initiation (booting) stages are the main nitrogen windows. Splitting nitrogen across these stages prevents lodging and raises grain set.

Q: Why does rice need silicon?

Rice is a silicon-accumulating crop. Silicon strengthens stems against lodging and raises resistance to blast and sheath blight.

Key Points

Tillering and booting: main N windows

Panicle fertilizer secures grain number

Silicon: lodging and disease resistance

Zn and B matter on deficient soils
