Pemanfaatan Pupuk Organik Cair Dari Kolam Limbah Kelapa Sawit dan Pupuk Hayati Biofertilizer Pada Bibit Kelapa Sawit (Elaeis Guinensis Jacq) di Main Nursery Pada Umur 8 - 12 Bulan

Abstract

This research was conducted in the experimental garden of the Faculty of Agriculture, University of Medan Area, Jalan Kolam No. 1 Medan Estate, Percut Sei Tuan Subdistrict with a height of 12 m above sea level, flat topography and alluvial soil types, October to February 2019. The design used in this study was Non Factorial Randomized Block Design (RCBD). With the factor of liquid organic fertilizer treatment from palm oil waste ponds (L notation) which consists of 4 levels of treatment, namely: L0: Recommendation for fertilizing oil palm seedlings in the main nursery L1: Provision of liquid PKS fertilizer at a dose of 75 cc / polybag L2: Provision of fertilizer PKS liquid with a dose of 150 cc / Polybeg L3: Provision of PKS liquid fertilizer with a dose of 225 cc / polybag. While the treatment of biological fertilizer application Biofertilizer B0: Without Biofertilizer B1: Giving Biofertilizer with a concentration of 0.1% B2: Giving Biofertilizer with a concentration of 0.2% B3: Giving Biofertilizer with a concentration of 0.3%. This research was conducted in 2 replications. The parameters observed in this study were plant height, stem diameter, number of leaves and leaf area. The results obtained from this study are: 1) Organic Fertilizer The application of liquid organic fertilizer from palm oil waste ponds showed a very significant effect on the observed parameters, namely: seed height, stem diameter, number of leaves, leaf color and leaf area. In this case the provision of liquid waste from palm oil waste ponds with a dose of 225 ml / polybag is the best treatment in supporting growth and development of oil palm seedlings. 2) Biofertilizer biofertilizer shows a very significant effect on the observed parameters: seedling height, stem diameter, number of leaves, leaf color and leaf area. In this case the application of Biofertilizer biofertilizers with concentrations of 0.3% is the best treatment in supporting growth and development of oil palm seedlings. 3). Giving a combination of liquid organic fertilizer treatment from palm oil waste ponds and Biofertilizer biofertilizer has no significant effect on all vegetative measurement parameters.
