Hot Water Treatment of Oil Palm Decanter Cake (OPDC) For Bio-organic Media of Oil Palm Seedlings
Publication Date : 20/06/2019
OPDC has high potential to be used as organic media for oil palm seedlings due to its substantial nutrient content. However, residual oil in OPDC could give negative effect to plant growth. This study was conducted to examine the potential of hot water-treated OPDC as bioorganic media and its effects on growth performance of oil palm seedlings. OPDC was treated with hot water to remove oil content and chemical analysis was determined on N, P, K, Ca and Mg. Then, treated OPDC was mixed with MPOB F1 fertilizer and soil at 25%, 50% and 75% to be used as bioorganic growing media. The results showed that after hot water treatment, residual oil was reduced from 15% to 10-11%. Once applied as planting media, highest growth performance and biomass accumulation was recorded by mixture of 25% treated OPDC with soil and MPOB F1 fertilizer. Plant height, stem girth, leaf number, leaf area, leaf dry weight, stem dry weight and root dry weight were improved by 28%, 15%, 10%, 60%, 72%, 45% and 18%, respectively as compared to control. In conclusion, appropriate amount of treated OPDC addition in growing media could improve the growth of oil palm seedling after oil content removal.
