This calculator is produced by the Dept of Primary Industries in WA to assist with determining canola seeding rates.
The calculator requires you to enter information to calculate the seeding rate
- decide how many plants per square metre to have (the target density)
- estimate field establishment,
- find out the seed size (or seeds per kg)
- and germination percentage
You can then feed this information into the online seeding rate calculator or a hand held calculator, to get the seeding rate.
There is also reference to the companion page Canola seeding rate information for information about selecting suitable density targets and field establishment. Also refer to this page for information to do calculations using a hand held calculator, instead of this online version.The seed size (number of seeds per kg) is supplied for all purchased canola seed, either on the bag or available from the seed supplier. For any retained open pollinated seed, refer to Estimating the size of retained canola seed for assistance to estimate the seed size.
