rice growth stages

  • 01 Germination (0–7 days)
    • The seed absorbs water and begins sprouting.
    • The radicle (root) and plumule (shoot) emerge.
  • 02 Seedling Stage (7–21 days)
    • The first leaves appear, and roots develop.
    • The plant establishes itself in the soil.
  • 03 Tillering Stage (22–45 days)
    • The plant produces multiple stems (tillers).
    • More leaves and roots develop.
  • 04 Stem Elongation (45–60 days)
    • The plant grows taller, preparing for reproductive growth.
    • Nutrients and energy accumulate for panicle formation.
  • 05 Panicle Initiation (60–80 days)
    • The plant begins forming panicles inside the stem.
    • Leaves continue growing, but the focus shifts to reproduction.
  • 06 Booting Stage (80–90 days)
    • The panicle swells inside the leaf sheath.
    • The plant prepares for flowering.
  • 07 Heading Stage (90–100 days)
    • The panicle emerges from the leaf sheath.
    • The flowers (spikelets) are exposed.
  • 08 Flowering Stage (100–110 days)
    • The flowers bloom, pollinate, and begin forming grains.
    • This is a critical stage for yield.
  • 09 Milk Stage (110–120 days)
    • Developing grains contain a milky, liquid endosperm.
    • The plant remains green and actively transports nutrients.
  • 10 Dough Stage (120–130 days)
    • The grains thicken, with starch accumulation.
    • The plant begins to yellow as it nears maturity.
  • 11 Maturity Stage (130–150 days)
    • Grains harden and turn golden brown.
    • The plant is ready for harvest.
  • 12 Senescence & Death (After 150 days)
    • Leaves dry out, and the plant stops growing.
    • If unharvested, the plant dies naturally.
