## Seed Rate Formula

The following two example problems outline the steps and information needed to calculate the Seed Rate.

**SER = TPP * TWG * 100**

- Where SER is the Seed Rate (kg/ha)
- TPP is the target plant population (p/m^2)
- TWG is the TGW (thousand gram weight) (g)

## How to Calculate Seed Rate?

The following example problems outline how to calculate Seed Rate.

Example Problem #1:

- First, determine the target plant population (p/m^2).
- The target plant population (p/m^2) is given as: 30.

- Next, determine the TGW (thousand gram weight) (g).
- The TGW (thousand gram weight) (g) is provided as: 60.

- Finally, calculate the Seed Rate using the equation above:

SER = TPP * TWG * 100

The values provided above are inserted into the equation below and computed.

SER = 30 * 60 * 100 = 180,000 (kg/ha)

Example Problem #2:** **

For this problem, the variables required are provided below:

target plant population (p/m^2) = 50

TGW (thousand gram weight) (g) = 100

Test your knowledge using the equation and check your answer with the calculator..

SER = TPP * TWG * 100** = ?**
