Paddy Yield Estimator
Estimate paddy yield and total grain mass from your field area and yield-component assumptions.
A QUICK WALKTHROUGH
How to use this tool
- Enter area and all yield assumptions; no values are preselected.
- Use your own representative assumptions. Enter filled spikelets as 0–100%; the formula uses F/100. Keep grain weight on a consistent moisture basis; no moisture correction, milling recovery or harvest losses are applied. This is an estimate, not a harvest guarantee or agronomic advice.

Formula and assumptions
Y (t/ha) = H × P × S × (F / 100) × W / 100,000; T (t) = Y × A (ha). Use your own representative assumptions. Enter filled spikelets as 0–100%; the formula uses F/100. Keep grain weight on a consistent moisture basis; no moisture correction, milling recovery or harvest losses are applied. This is an estimate, not a harvest guarantee or agronomic advice.
