What is a Crop Yield?

Crop yield is a measurement of the amount of agricultural production harvested per unit of land area. It is the primary metric farmers use to evaluate the success of a growing season and the overall productivity of their fields.

Usually expressed in standard units like bushels per acre (bu/ac) or kilograms per hectare (kg/ha), understanding crop yield is essential. It tells a farmer exactly how much usable product was generated, allowing them to calculate profitability, assess the impact of weather or fertilizer changes, and secure accurate crop insurance.

How Our Calculator Works

We process your scouting inputs using standard agronomic yield formulas to give you accurate harvest projections.

Input Field Data

Enter your estimated harvestable plant population, along with the average ears/pods per plant and seeds per pod.

Apply Seed Traits

Provide the specific seed weight (seeds per pound) and standard test weight for your specific crop type.

Instant Projection

Our algorithm calculates total seeds per acre, converts it to gross weight, and outputs the estimated yield in standard bushels.

Standard Bushel Weights

Use these standard test weights (lbs/bu) to ensure accurate conversions.

Crop Type	Standard Weight (lbs/bushel)
Shelled Corn (Maize)	56 lbs
Soybeans	60 lbs
Wheat	60 lbs
Barley	48 lbs
Oats	32 lbs

Formula Used for Crop Yield Calculator

This calculator uses the standard agronomic yield component formula, converting raw seed counts into standard volume (bushels).

Crop Yield Calculation Examples

Sample inputs for corn, soybeans and wheat. These are illustrative averages, so use your own field counts for a real estimate.

Corn (Grain)

32,000 plants/acre × 1 ear × 600 kernels = 19.2 million kernels/acre. At 1,500 kernels per lb that is 12,800 lbs, and at 56 lbs/bu:

≈ 228.6 bu/acre

Soybeans

140,000 plants/acre × 30 pods × 2.5 seeds = 10.5 million seeds/acre. At 2,800 seeds per lb that is 3,750 lbs, and at 60 lbs/bu:

≈ 62.5 bu/acre

Wheat

1,000,000 plants/acre × 2 heads × 30 kernels = 60 million kernels/acre. At 14,000 kernels per lb that is about 4,286 lbs, and at 60 lbs/bu:

≈ 71.4 bu/acre

Frequently Asked Questions

A Crop Yield Calculator estimates how much grain a field will produce per acre. It uses counts you take in the field (plants, ears or pods, and seeds) together with seed weight and test weight, so you can predict the harvest before the combine runs.

Multiply plants per acre by ears (or pods) per plant and by seeds per ear. Divide the total seeds by seeds per pound to get pounds per acre, then divide by the test weight to get bushels per acre.

Formula: Yield (bu/acre) = Plants × Ears × Seeds ÷ Seeds per lb ÷ Lbs per bushel

You need five numbers: harvestable plants per acre, average ears or pods per plant, average seeds per ear or pod, seed weight in seeds per pound, and the test weight in pounds per bushel for your crop.

Yes. The same method works for corn, soybeans, wheat, barley and oats. Change the seeds per pound and the test weight to match your crop, using the Standard Bushel Weights table above.

Measure 17 ft 5 in of row in 30-inch rows (this equals 1/1000 of an acre), count the plants in that length, and multiply by 1,000. Repeat in several spots across the field and average the results.

It is an estimate. Accuracy depends on how many places you sample and how well your counts represent the field. Weather late in the season, grain moisture and harvest losses can all move the final yield.
