Abstract
Sweet potato is a high yielding root crop adaptable to wide ecological condition. With little intervention needed. Farmers are able to invest minimally with the ever increasing demands. Farmers are able to maximize their investment returns within a short period of time. One limiting factor for sweet potato is lack of desirable varieties with high yield, potential nutritive value and resistant to insect pest and diseases and early maturing characteristics. This study was conducted at Brgy. Sto. Rosario San Juan, La Union from December 1, 2016 – March 5, 2017.
The different sweet potato varieties V1- Taiwan, V2- Peniazuma, V3- Kalbo-oy,
V4- Imitlog, V5- Bengueta, V6- Haponita and V7- Farmers were randomly distributed
following Randomized Complete Block Design (RCBD) with three replication. Planting
materials used were terminal sweet potato cuttings that are vigorous and 30 cm long. The cuttings were planted at one cutting per hill, at a distance of .30 cm between hills and .75 cm between rows with a total of 40 plants per plot. Harvesting was done 90-95 days after planting depending on the variety.
Based from the research finding all sweet potato varieties tested under San
Juan, La Union condition performed comparably in terms of days to maturity, number of
storage roots, weight of storage roots, weight of marketable tubers, weight of fresh
biomass, number of marketable tubers and yield of storage roots in kg/plot and kg/ha..
