PENGARUH PUPUK ORGANIK CAIR DARI BONGGOL PISANG TERHADAP KADAR HARA NITROGEN TOTAL DAN C-ORGANIK PADA BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.)

Suspension media is made of natural ingredients to multiply microorganisms that can accelerate the destruction organic matter. Banana hump contains water, iron, phosphorus, calcium, carbohydrates, calories and protein, which are potential as fertilizers. Application banana weevil fertilizer expected increase carrying capacity soil for availability matter nutrients. The purpose this study was determine best concentration or dose liquid on vegetative growth oil palm (Elaeis guineensis Jacq.) seedlings in Main Nursery. Based statement, research compiled with object This conducted Nursery Practice Garden area at STIP-AP Medan. Soil analysis carried out Laboratory Agricultural Technology Research Institute (BPTP) North Sumatra. time 8 months, from January 2021 - August 2021. used a Randomized Block Design (RAK) 2 factors, namely Factor (1) Liquid Organic Fertilizer Cobs (2) Compound (NPK) 16:16 :16. treatment repeated 3 times, number samples being plants so sample population 54 plants. Parameters observed were seedling height, stem circumference, leaves, leaf width, root wet weight, shoot dry total nitrogen nutrient content C-organic content. data obtained analyzed statistically by variance (ANOVA) 5% 1% significant difference tests. results showed compound had no effect parameters. However, biomass formed significantly affected indicated weight parameter. nutrients Ultisol very low classification values ​​of 0.07 – 0.09% 0.22 0.54%.
