SG 94 17 17 is a registered sweet potato variety, also sold or known as UPL Sp 14 or NSIC Sp 23. It was registered with the National Seed Industry Council in 2000 as NSIC 2000 Sp 23. It takes about 120 days from planting to harvest, with 13 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.
