Pulse School: 1,000 Kernel Weight & The Optimum Plant Stand

Pulses are well-known for their nitrogen-fixing capacity but not for their competitiveness. Weed pressure can really knock back yield, a situation made worse by a thin stand or early-season disease. Two key seeding management strategies for pulses are seeding rates based on an optimal plant stand count and disease control planning. Achieving the best established number of plants must take in to consideration seed mortality and also seed size.

In this episode of the Pulse School, Wes Anderson, agronomy manager for Richardson Pioneer, stresses the importance of measuring the thousand kernel weight of each crop prior to seeding. This is especially important in peas, as seed size differences can mean the difference between an optimal plant stand count and one that falls well short of what’s needed for early-season competitiveness. Anderson lists the stand density to strive for by crop type, and explains how to choose a reasonable mortality figure when doing your seeding calculation.

Area One Farms Serve as Equity Partners in Ontario’s North

If there's one thing expanding farming in Northern Ontario will require, it's money. Financial backing. Bankrolling. Investment. Whatever name you give it, securing land is only a part of the cost of starting farming — new land must be cleared, cleaned up, and tiled if it's to be improved to at least a Class 3.…Read more »
