Amaranth — Harvesting

Metadata research draftEvidence limits

⚠️ Status: drafted from the literature survey. Values Unknown until source notes/full text.

Maturity indicators

• Grain amaranth matures in a terminal panicle with many tiny seeds; the whole plant dries down. Seed-moisture and panicle-color/maturity cues — Unknown.
• Seed-moisture at harvest affects threshing/quality (candidate 10.15258/sst.2004.32.1.15). Target seed moisture for grain — Unknown.

Harvest window

• Evenness of maturity across a plot and the harvest window before shatter — Unknown. Grain amaranth can shatter if left too late (seed-shattering risk flagged).

Manual harvesting

• Cut entire plants when panicles dry, or whole-plant at maturity — technique Unknown.
• Labor (h per kg or m²) — Unknown; core human-scale research question (mirrors chia; academic literature silent).
• Mexico smallholder practice — flagged, not yet sourced.

Losses

• Shatter loss at/after maturity, handling losses — Unknown.

Weather

• Dry conditions; rain near harvest risks loss/quality — Unknown.

Equipment

• Hand tools (sickle/knife); potential shade-drying of cut plants — Unknown.

Structured-data impact

• Feeds harvest (manual_time_h_per_kg, shatter_risk) of data/crops/amaranth.yaml once evidence exists.
