Count a few plants, get your tonnes per acre. Free crop-cutting and yield estimators for grains and vegetables.
Estimate wheat yield before harvest from plants/m², ears (tillers) per plant, grains per ear and grain weight — the components-of-yield method.
Estimate rice (paddy) yield before harvest from plants/m², panicles per plant, filled grains per panicle and grain weight — the components-of-yield method.
Estimate maize yield before harvest from plants/m², cobs per plant, grains per cob and grain weight — the components-of-yield method.
Convert a quadrat grain weight into yield per hectare — the crop-cutting experiment method.
Estimate tomato yield per acre and per hectare from plant spacing and yield per plant.
Estimate gross revenue and profit from expected yield, market price, area and cost.
Compare your actual yield with the achievable potential to quantify the yield gap.
