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.

How long does it take, and how much does it yield?

Yoshida 1 soybean takes about 70 days from sowing to harvest. That is 12.6 days faster than the average of the 22 soybean varieties with a day count, 82.6 days. A shorter crop frees the field sooner and dodges more of the weather, while a longer one often fills more.

Its average yield of 8 t/ha beats the average of its group, 2.52. It sits in the top quarter of its group. Trial yields come from well managed plots, so your own will depend on water, fertilizer, pests and timing.
