Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds germinate in 7-10 days; seedlings emerge with primary leaf visible

Ensure soil moisture for germination; protect from birds if necessary; keep area weed-free

2

Tillering

3-4 weeks

Multiple shoots develop from base; plant becomes bushy with 4-6 tillers per plant typical

Apply balanced fertilizer if soil fertility is low; monitor for early pests and diseases

3

Stem Elongation & Heading

4-5 weeks

Plant grows upright (24-30 inches tall); head emerges from boot; awns become visible

Reduce nitrogen to prevent lodging; ensure adequate but not excessive water; stake if tall varieties tend to fall

4

Anthesis & Grain Filling

3-4 weeks

Flowers bloom; grains develop and fill with starch; heads droop slightly as they mature

Monitor for mildew and rust; do not overwater; allow air circulation to prevent fungal issues

5

Maturity & Harvest Readiness

1-2 weeks

Heads turn golden-yellow; grains harden; plant dries down; stems become brittle

Stop watering; allow full maturation for best grain quality; harvest when moisture content drops below 15%

Harvest Tips

Harvest when heads turn golden-yellow and grain is hard (cannot be dented with fingernail). Cut stems 2-3 inches above ground using sickle, scythe, or combine harvester. Tie in bundles and cure in a dry location for 2-3 weeks. Thresh to separate grain from chaff by beating dried bundles, winnowing, or mechanical threshing. Store grain in cool, dry conditions with moisture content below 12%.
