How to Use This Calculator
  1. Enter plant population per acre and average ears or pods per plant.
  2. Set the average seeds per ear or pod and seed weight.
  3. Input harvest moisture percentage and total field size in acres.
  4. Review estimated yield in bushels per acre and total field bushels.
  5. Use yield estimates for crop insurance adjusters, marketing decisions, and storage planning.

What each input means

Plant Population
Actual harvested plant population in thousands per acre. Count plants in a known area and scale up.
Ears/Pods per Plant
Average number of ears (corn) or pods (soybean) per plant. Corn typically has 1; soybean may have 30-50 pods.
Seeds per Ear/Pod
Average kernels per ear or seeds per pod. Corn: 400-600 kernels/ear. Soybean: 2-4 seeds/pod.
Seed Weight
Average weight of one seed in grams. Corn kernel: ~0.30-0.40g. Soybean: ~0.15-0.20g.
Harvest Moisture
Grain moisture at harvest. Standard for pricing: corn 15.5%, soybean 13%, wheat 13.5%.
Field Size
Total field area in acres.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Plant Population = 32, Ears/Pods per Plant = 1, Seeds per Ear/Pod = 500, Seed Weight = 0.35 = 6 input(s) provided
  2. Calculate Estimated Yield
    Estimated Yield = bu
    208.7 = 208.7
  3. Calculate Total Field Bushels
    Total Field Bushels
    33395 = 33395
  4. Calculate Total Weight
    Total Weight
    935.1 = 935.1
