Use this crop irrigation yield forecast calculator to turn operational assumptions into a clear planning estimate. Enter the measurements from your project, field, or greenhouse, then review the main result alongside the supporting totals. The calculator keeps the formula visible so you can check units, compare scenarios, and understand exactly which assumptions drive the answer.
The forecast separates agronomic yield change from the share expected to be lost before sale or storage.
Run conservative and optimistic cases instead of relying on a single percentage change.
For 120 acres at 165 units/acre, a 4% improvement gives 171.6 units/acre. After 6% loss, marketable yield is 19,358 units.
The result changes directly with the quantities in the formula. Change one field at a time to see which operating assumption has the largest effect on marketable.
Use the units printed beside each field. Convert measurements before entering them when a different unit is shown, because the built-in constants assume the displayed units.
Run separate scenarios for each period or operating condition, then add the applicable totals. A single blended input can hide important peaks and delays.
No. It includes only the losses, efficiency factors, or allowances shown in the input panel. Add separate allowances for conditions not represented.
Actual performance can differ because of measurement error, weather, equipment condition, work sequencing, material variability, and the quality of the assumptions entered.
