Seed size can vary significantly, making planting by weight or volume alone a rather untrustworthy endeavour. So it’s no wonder calculating seeding rates based on the thousand kernel weight (TKW) of the desired crop is advised by so many researchers and agronomists.
In this Wheat School, Richard Marsh of Syngenta re-joins Lyndsey Smith to compare plant stands achieved using thousand kernel weight versus those with seeding rates in pounds per acre in an adjacent field. Marsh discusses how to scout when assessing plant counts and provides a simple description of the math to use when calculating whether or not you’ve met your target stand.
