Uji Konsentrasi Dan Pemberian POC NPK Terhadap Pertumbuhan Bibit Tanaman Kelapa Sawit (Elaeis quineensis Jacq) di Pre Nursery

This study aims to determine the concentration test of NPK POC application on the growth of oil palm seedlings (Elaeis guineensis Jacq) in the prenursery and their interaction. The research was conducted in Kelambir V Village, Hamparan Perak Subdistrict, Deli Serdang Regency. This study used a factorial randomized block design (RBD) consisting of 2 treatment factors with 16 treatment combinations and 2 replications. The first treatment was the NPK POC concentration test consisting of 4 levels of P1 = 1%, P2 = 2%, P3 = 3% and P4 = 4%. The second treatment of NPK POC application (D) consists of 4 levels, namely D1 = 50 ml / polybag, D2 = 100 ml / polybag, D3 = 150 ml / polybag and D4 = 200 ml / polybag. Parameters observed were plant height (cm), number of leaves (blade), leaf area (cm) and stem diameter (cm). The results obtained showed that the NPK POC administration showed significant results for each observation parameter. The NPK POC concentration test and the interaction between the NPK POC concentration test showed insignificant results for each observation parameter.
