Abstract—Modified of urea fertilizer with lignin’s palm empty bunch was applied to lettuce growth. This research aims to enhance the utility value of lignin from palm empty bunch, investigate slow release of urea-lignin fertilizer and vegetative aspect of leaves lettuce after period of week. Application of fertilizer was done in two difference places, namely green house laboratory and traditionally environment. Research showed that fertilized using urea fertilizer which modified by 2 % of lignin resulted amount (pc), length (cm) and wide (cm) of lettuce leave is better than fertilized only by urea in laboratory scale. Amount (pc), length (cm) and wide (cm) average of fresh lettuce leaves using urea modified by 2 % lignin resulted 8 pieces, 12 cm and 11 cm respectively on 6 weeks after plantation. Furthermore in traditionally environment, amount (pc), length (cm) and wide average (cm) of fresh lettuce leaves by using urea modified 3% lignin resulted 14 pieces, 25 cm and 21 cm consecutively on 6 weeks after plantation.
Index Terms—Lignin, lettuce, palm empty bunch, urea.
