Effect of Blotong (Sugarcane Waste) and Urea Fertilizer Application on the Growth of Oil Palm Seedlings (Elaeis guineensis Jacq.) In Polybags
Abstract
Blotong is a problematic waste for sugar factories and the community because wet blotong causes a foul odor. The specific nutrient content in the blotong is quite high, so it can improve the physical properties of the soil and as a source of nutrients that can benefit plants. The purpose of this study was to determine the effect of giving blotong and urea fertilizer on the growth of palm oil seedlings. This research was conducted in Sidodadi, Kisaran Barat Subdistrict, Asahan Regency, North Sumatra Province, with the elevation of ± 25 meters above sea level, flat topography, and climate type C. This research was conducted in January to April 2019. This research was conducted using a factorial randomized block design with the first treatment factor giving blotong, namely B0 = without giving blotong (0 g / polybag), B1 = 150 g / polybag, B2 = 300 g / polybag and B3 = 450 g / polybag. Whereas the second treatment factor for urea fertilizer is U0 = without urea (0 g / polybag), U1 = 100 g / polybag and U2 = 200 g / polybag. The parameters observed were seedling height, stem diameter and leaf area. The results showed that the administration of blotong significantly affected seedling height, stem diameter and leaf area of oil palm seedlings; and urea fertilizer treatment showed significant effect on seedling height and stem diameter of oil palm seedlings.Copyright (c) 2020 Rina Maharany, Deddy Wahyudin Purba
