Greenhouse Crop Yield Calculator

Plan greenhouse crop output from bed geometry, plant spacing, crop cycles, survival, yield per plant, packout, and usable floor area.

Protected-crop production

Convert bed geometry and crop cycles into annual marketable greenhouse output

The model counts planting positions, then applies survival, yield per producing plant, packout, and completed cycles.
Planting positions1,680
Producing plants1,613
Marketable crop / cycle7,044 kg
Completed cycles / year2.94
Annual marketable crop20,735 kg
Annual yield intensity23.0 kg/m²

Space and time view

Bed planting map with annual crop-cycle calendar

Dots show live planting positions; the calendar rail separates crop occupancy from turnaround days.

Detailed calculation process

Physical planting positions constrain output before crop performance does

General symbolic formulas

S = B × R × floor(100L / s)P = S × vYc = P × y × qC = 365 / (d + t)Ya = YcCI = Ya / A

Spacing is converted from centimetres to positions along each bed. Survival and packout are distinct losses; cycle length plus turnaround determines annual frequency.

Use steps

  1. Measure usable bed length, excluding work zones.
  2. Use harvested producing-plant yield.
  3. Include sanitation and reset time between crops.

Examples

Closer spacing: test 32 cm only if canopy and airflow remain acceptable.

Long crop: extend cycle days to reflect a winter light period.

Limitations

Uniform plants and cycles are assumed. The model omits staggered harvests, light, temperature, disease, crop changes, labor bottlenecks, aisle changes, and partial final cycles.

Greenhouse yield FAQ

Why use floor area for intensity?

It reflects the whole greenhouse footprint, including aisles and service space.

Are partial cycles counted?

The annualized result uses a fractional frequency; the table shows only completed cycles.

Why separate survival and packout?

Survival removes plants; packout removes harvested product that cannot be sold.
