Sorghum Yield Estimator
Estimate sorghum (jowar) yield before harvest from plants/m², panicles per plant, grains per panicle and grain weight — the components-of-yield method.
Sorghum carries ~18 heads/m², each with up to 2000 grains at a small ~28 g thousand-grain weight. Sample several 1 m² quadrats across the field and average them for a reliable pre-harvest estimate.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Farmers, FPOs and crop insurers use the free Sorghum Yield Estimator to predict yield before harvest from a few quadrat counts — no waiting for the threshing floor.
About Sorghum Yield Estimator
Estimate your sorghum (jowar) yield weeks before harvest using the universal components-of-yield method. Sorghum carries ~18 heads/m², each with up to 2000 grains at a small ~28 g thousand-grain weight. The formula multiplies plants per m² × panicles per plant × grains per panicle × thousand-grain weight to give grains per m² and then yield: yield (kg/ha) = grains/m² × (1000-grain weight ÷ 1000) × 10. Count the components from a few representative one-square-metre quadrats, enter them here, and read the estimated yield in quintals and tonnes per hectare and the total for your field.
How to use Sorghum Yield Estimator
- 1Count plants in a 1 m² quadrat at several spots and average.
- 2Count the panicles per plant and grains per panicle, and use the thousand-grain weight (weigh 1000 grains, or use the default).
- 3Read the estimated yield per hectare and for your whole field.
Why use Sorghum Yield Estimator?
- ✓Predicts yield before harvest from simple field counts
- ✓Uses realistic default components for sorghum (jowar)
- ✓Outputs q/ha, t/ha and total field yield
- ✓Free, instant and fully in-browser
Frequently asked questions
How do I estimate sorghum (jowar) yield before harvest?+
Use the components of yield: plants/m² × panicles per plant × grains per panicle gives grains/m²; multiply by the thousand-grain weight ÷ 1000 for grams/m², then ×10 for kg/ha. Sample several quadrats and average for accuracy.
What is a good yield for sorghum (jowar)?+
Sorghum carries ~18 heads/m², each with up to 2000 grains at a small ~28 g thousand-grain weight. Yields vary widely with variety, soil and management — this tool lets you estimate your specific crop rather than rely on a district average.
Why count several quadrats?+
Crops vary across a field. Averaging counts from several representative one-square-metre quadrats (avoiding edges and gaps) gives a far more reliable estimate than a single spot.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline in the field and your data never leaves the device.
