Critical Mistakes Made with Soybeans - Planting date, cultivar, maturity & heat
When making the choice to plant soybeans there are crucial elements to take heed of. Capstone Seeds has put together some of that information here to make that process a little easier.
E.g. 1 Initiate flowering in Early January: Different Cultivar Maturity required for different Latitudes.
E.g. 2 13.1 hour day-length: The same cultivar will flower on different dates at different latitudes.
E.g. 3 13.5 hour – ideal for Polokwane (+/- MG6) = Very Late Maturity in PE but too quick in Harare
Late maturity next to early maturity (Maclear)
Early maturity next to medium maturity (Maclear)
In cool areas a late maturity cultivar planted too late will not mature before the cold months come.
Planting date in soybeans is more important than maize. Make it the priority.
· Plant before maize.
· Plant early in cool areas (but after the critical date), because growth is much slower.
· Plant a quick maturity cultivar for the latitude so it matures during the warm part of the season.
In eastern coastal belts rainfall peaks earlier than inland areas
· On the same latitude earlier maturity cultivars must be planted near the coast and later maturity cultivars as you go west.
In warmer areas plant a combination of maturity groups to spread your risk.
· Plant early maturity first and later maturity last.
