PSB Sp 17 Sweet Potato (Sp 17 kamote): Characteristics
PSB Sp 17 sweet potato is an improved clone sweet potato variety, also sold or known as Sp 17 kamote or SP17. It is not a registered variety, so the facts here come from its seller and farm sources.
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.
