UPL Bs 4 Sitao: Yield, Maturity and Characteristics
UPL Bs 4 sitao is a bush sitao variety. The Philippine Seed Board approved it in 1990. It takes about 45 days from sowing to the first harvest, with 11.09 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.
