Conseils de culture
Maintain 5-10 cm standing water during vegetative and reproductive stages for optimal paddy rice growth.
Apply nitrogen fertilizer in 3 split doses: at transplanting, mid-tillering, and panicle initiation for maximum uptake efficiency.
Alternate wetting and drying (AWD) irrigation saves 15-30% water without yield loss — let fields dry briefly between flooding cycles.
Monitor for rice blast during cool, humid weather — fungal spores spread rapidly under these conditions.
Transplant seedlings at 20-25 days old for optimal establishment. Older seedlings recover slowly and tiller less.
Control weeds in the first 30 days after transplanting — this is the critical weed competition period.
