About Crop Yield Calculator
Grain yield can be estimated before harvest from its yield components. Grains per square metre are plants × ears per plant × grains per ear. Multiplying by the thousand grain weight and dividing by 1,000 gives grams per square metre, and dividing that by 100 converts it to tonnes per hectare. Counts taken in several places across the field give a better estimate. Harvest losses and grain moisture are not accounted for.
