PENGARUH INTERAKSI ANTARA PEMBERIAN BIOFOSFAT DENGAN PENGGUNAAN KULTIVATOR LOKAL UBI JALAR TERHADAP PERTUMBUHAN HASIL DAN KANDUNGAN GULA TANAMAN UBI JALAR

This study aims to examine the effect of interaction between administration biophosphate and use local Jakar potato cultivars on growth, yield sugar content sweet plants. The research method uses (RAK) 4 times. 1st factor was Biophosphate (B), consisting two levels: b1 (100 kg/ha biophosphate) b2 (200 biophosphate). second Sweet Potato Cultivar (K), three k1 (cilembu), k2 (maja) k3 (brass white). Differences in treatment means were tested using Duncan's multiple range test at 5% level. results showed that bophosphate had no effect. Phosphate did not have a different all growth variables content.
