| description | Use when modelling a cultivated plant type as the agricultural SKU — the produce-catalogue row carrying its sale unit (1 bunch, 100 g, 1 head), unit price, and the agronomic constants (yield per area, plant spacing, N·K₂O need, plantings & harvests per season) that explode a demand quantity into land, seed, and fertility. The crop is the bill-of-materials line of a farm; its heterogeneous sale unit is why automatic unit conversion is non-negotiable. |

crop — the cultivated plant as the agricultural SKU
A crop is one cultivated plant type treated as a sellable line — the agricultural [[items|item]]/SKU. It is where the living [[biological/assets|biological asset]] meets [[commerce]]: each crop carries a sale unit (the [[measure]]: 1 bunch · 100 g · 1 head · 1 quart · 2 lbs) and a unit price (the [[currency]] [[amount]]), plus the agronomic constants that make it plannable — [[yield]] per area, plant spacing (within-row, between-row, rows-per-bed), seed rate (per 100 ft / per area), nitrogen & potassium need ([[fertility]]), and the scheduling pair number of [[planting]]s (successions) × number of [[harvest]]s (pickings).
These constants are exactly the bill-of-materials line of [[agriculture]]'s backward plan: a demanded quantity of crop units explodes — via unit weight, yield, spacing, and fertility rate — into row-length, land, seed, and fertilizer. The crop's heterogeneous sale unit is the reason automatic [[conversion]] is non-negotiable: a [[share]] box mixes grams of arugula, bunches of beets, heads of lettuce, pounds of potato, and the only way to total or cost them is to carry each as a [[measure]] (value + UN/CEFACT unit) and a [[currency]] amount and let them [[rate|convert]] and [[balance|sum within their dimension]] — never as the text "2.00 лв" that breaks the arithmetic.
A crop is cool-season or warm-season (its [[season]] band), a heavy or light feeder (its [[fertility]] class), and legume or not (nitrogen-fixing ⇒ N ≈ 0); a fruiting crop sets its harvest only with [[pollination]]. Ranked by net return per bed-foot (the [[enterprisebudget|crop enterprise budget]]: units × price − seed − inputs − labor), it is also the unit of the drop-the-unprofitable decision.
Standards
- Johnny's Selected Seeds — Grower's Library crop charts (yield/100 ft, seeds/ft, spacing)
- Southeastern U.S. Vegetable Crop Handbook (per-crop planting & fertility recommendations)
- Wiswall — crop enterprise budgets (net return per crop)
- UN/CEFACT Rec 20 (sale-unit codes); ISO 4217:2015 (unit-price currency)
Common mistakes
- A unit-baked field (
weightKg, a price typed 2.00 лв) — split into [[measure]] (value + unit) and [[currency]] (amount + code) so totals and conversions are automatic.
- Treating all units as countable pieces — a box mixes weight, count, and volume units; sum only within a [[dimension]].
