Yield Calculator
- See how yield components affect yield.
- Then check below to see how crop management and the environment affect yield components.
Calculate how much yield to expect: |
|
|---|---|
| Enter # of cobs per sq m (usually 4-8): | |
| Enter # of grains per cob (usually 200-400): | |
| Enter the thousand grain weight (usually 150-300g): | |
| Your crop will yield approximately: | t/ha |
Remember: Build your yield
| How do I manage the # of cobs per square meter? | Good plant stand depends on good seed, good crop establishment (suitable plant density) and good early water and nutrient management. |
| How do I manage the # of grains per cob? | Water and nutrient stress seriously affect final grain number (especially nitrogen deficiency and water stress). |
| How do I manage thousand grain weight (TGW)? | TGW is determined from flowering on and is greatly affected by water stress during grain fill. Choose a planting time or irrigate your crop to avoid stress during flowering and grain fill. |
Economics Calculator
Farmers want to know costs.
The following calculator estimates how much grain is needed to pay for a new practice.
Grain needed to pay for a new practice: |
|
|---|---|
| Enter the cost of the new practice: | local currency units |
| Enter the market price for grain: | local currency units per ton |
| You need approximately: | kg grain to pay for the new practice |
