Wide row soybeans are making a comeback in Ontario.
One of the benefits of the system is the ability to potentially reduce seed cost. But soybean varieties are not created equal, especially when it comes to delivering top yields and profitability in 30-inch rows.
In this episode of Real Agriculture Soybean School, Pride Seeds market agronomist Aaron Stevanus looks at a soybean trial comparing plant populations of 100,000 and 200,000 in wide rows.
He reviews a range of agronomic and physiological factors – from growth rate and canopy closure to height, flowering, standability and yield – that need to be considered when picking the most profitable population.
As Stevanus concludes, there is no hard and fast rule for picking populations for 30-inch row success. It really comes down to genetics. Throughout the trial there are examples of varieties that deliver the most profitable return at 200,000 plants while others put more money in growers pockets at 100,000.
