Nursery/Seedling Stage
30-40 daysRice seeds germinate and develop first leaves in seed beds or containers; seedlings appear bright green with 2-4 leaves
Maintain water level of 1-2 inches in seedbed; keep seedlings at 20-25°C if possible; protect from birds; fertilize lightly with balanced fertilizer
Transplanting
1-2 weeks transitionSeedlings reach 3-4 leaf stage with height of 4-6 inches; ready to be transplanted to main paddy fields
Harden off seedlings gradually; transplant during early morning or overcast conditions; handle bundles carefully to avoid root damage; maintain flood irrigation in paddies
Vegetative Growth
60-70 daysPlants establish roots and develop tillers (shoots); stems thicken and more leaves emerge; plants grow 12-20 inches tall
Maintain 2-4 inches of standing water; apply split nitrogen fertilizer doses (basal, tillering, and panicle initiation stages); weed control at 30-50 days; monitor for diseases
Reproductive/Flowering
15-20 daysPanicles (flower clusters) emerge from the leaf sheaths; flowers are small, self-pollinating, and appear greenish-white; grain formation begins
Maintain consistent water levels; reduce nitrogen to prevent excessive vegetative growth; ensure proper drainage conditions; monitor for pest activity; avoid water stress during this critical stage
Maturation & Harvest
20-30 daysGrains fill and mature; panicles bend downward under grain weight; hulls turn golden-brown; moisture content decreases to 20-25%
Begin draining paddies 7-10 days before harvest to firm soil; harvest when 80-85% of panicles have turned golden; use mechanical harvester or hand cutting; dry grain to 13-15% moisture for storage

Harvest Tips
Harvest when 80-85% of panicles have turned golden-brown and grains have hardened (usually 150-165 days after planting). Cut panicles with sickle or mechanical harvester when grain moisture is 20-25%. Dry immediately to 13-15% moisture content for proper storage. Yamada Nishiki's quality depends on precise timing—harvesting too early results in immature grains, while waiting too long causes shattering and quality loss.
