Seedling
3-4 weeksYoung shoots emerge with 2-3 leaves, pale green color, thin upright growth
Maintain shallow water (1-2 inches) or moist seedbed. Keep paddies weed-free. Begin nitrogen fertilization if transplanting.
Vegetative
4-6 weeksPlant develops multiple tillers (side shoots), height increases to 12-18 inches, dark green foliage, roots establish deeply
Maintain 2-4 inches of standing water. Apply nitrogen fertilizer in 2-3 split applications. Monitor for weeds and pests. Ensure consistent water level.
Reproductive/Panicle Development
2-3 weeksFlowering shoots (panicles) emerge from leaf sheaths, distinctive seed head forms with grain-bearing spikelets, plant height reaches 24-30 inches
Maintain water level at soil surface. Stop or reduce nitrogen to prevent excessive plant height and lodging. Apply phosphorus and potassium. Protect from strong winds.
Grain Filling
3-4 weeksSpikelets develop white or yellowish flowers; grains enlarge and fill with starch, gradually changing from light green to cream color
Maintain gentle water circulation. Ensure consistent water availability but avoid extremes. Monitor pest populations, particularly stem borers.
Maturity/Harvest Ready
1-2 weeksPanicles bend downward under grain weight, kernels firm and chalky white, leaves yellow and dry from bottom up, moisture content 15-20%
Drain paddies 1-2 weeks before harvest. Allow remaining moisture to dry grain to 13-14% moisture for storage. Monitor for lodging and pest damage.

Harvest Tips
Harvest when 80-90% of grains are straw-yellow and moisture content reaches 13-14%. Cut panicles with sickle or use mechanical harvester. Thresh immediately to separate grains from chaff. Dry to 13% moisture for long-term storage. Nipponbare typically yields 40-60 bushels per acre under optimal conditions.
