Estimate canola yield from field area, seeding rate, germination rate, yield per plant, weather, plant vigor, variety potential, and harvest loss.
Important: This is an educational yield estimator. Real canola yield depends on field sampling, soil, moisture, disease, pest pressure, fertility, weather, variety, and harvest timing.

How the Canola Yield Calculator Works
The Canola Yield Calculator estimates yield from the number of established plants, the average yield per plant, and several crop-condition factors.
The key correction in this version is unit clarity. The plant stand multiplied by yield per plant gives grams per hectare. The calculator then converts that to kg/ha and t/ha.
Canola Yield Formula
First, estimate the effective plant stand:
Effective plant stand = Seeding rate × Germination factor
Then estimate adjusted yield per plant:
Adjusted yield per plant = Yield per plant × Weather factor × Vigor factor × Variety factor
Then calculate yield:
Yield g/ha = Effective plant stand × Adjusted yield per plant
Yield kg/ha = Yield g/ha ÷ 1000
Yield t/ha = Yield kg/ha ÷ 1000
Example Calculation
Field area = 20 ha
Seeding rate = 70,000 seeds/ha
Germination = 90%
Yield per plant = 12 g
Weather factor = 1.0
Vigor factor = 1.0
Variety factor = 1.0
Harvest loss = 5%
Effective plant stand:
70,000 × 0.90 = 63,000 plants/ha
Before harvest loss:
63,000 × 12 g = 756,000 g/ha = 756 kg/ha

Frequently Asked Questions
What is a typical canola seeding rate?
Seeding rate depends on region, variety, target plant population, and farming practice. This calculator lets you enter your own value in seeds per hectare.
Why does germination rate matter?
Germination rate controls how many planted seeds become established plants. Lower germination reduces plant stand and yield potential.
What does yield per plant mean?
It is the estimated grain mass produced by one productive canola plant, in grams.
Why does the calculator show total field production?
Yield per hectare is useful for comparison, while total field production estimates the whole field output.
