Select Tudela Black Soybean (Tudela Black): Yield, Maturity and Characteristics
Select Tudela Black soybean is a grain soybean variety, also sold or known as Tudela Black or black soybean. It was registered with the National Seed Industry Council in 2020 as NSIC 2020 Sy 17. It takes about 74 days from sowing to harvest, with 2 tonnes per hectare on average in the trials.
The average and top yields in tonnes per hectare come from the trials each variety went through to be registered with the NSIC, and from what the seed companies say about their own seed.
What farmers harvest today can be different. Newer harvest records, the season, the place, the soil, the water and the care all move these numbers over time.
So use them to compare varieties, not as a promise for your field. Ask your seller or your agriculturist how the variety did on farms near you in the last few seasons.
