More plants, more yield

Canola yield increases as plant population increases, according to this study. As plant population went from 20 plants per square meter up to 100 per square meter, yield also increased at all site years.

Uniform plant stand is also important, especially for low plant populations, this study found. (See Figure 1.) Overall, uniform planting produced 14 percent greater seed yield than non-uniform planting at low- to average-yielding sites when plant density was at or below 80 plants per square meter (roughly eight per square foot). At high yielding sites, uniform and non-uniform plantings resulted in similar seed yield — as long as plant density was greater than 60 plants per square meter.
