Abstract

This research aims to get the best combination dose of coal fertilizer and N,P,K Fertilizer. The research has been done on 10 years old mature oil palm marihat variety in estate oil palm PT Bumi Sawindo Permai Penyandingan Village, Muara Enim Regency, South Sumatera. This research start from July 2021 to December 2021. The design applied in this research was Randomized Block Design Factorial (RBDF) with 2 factors. The first factor was coal fertilizer with 3 treatment levels and the second factor was a single dose of N, P and K fertilizer from Urea, TSP and KCl with 3 treatment levels, so there are 27 sample trees. The dose of coal fertilizer used consists of B0 = Without Coal Fertilizer (Control); B1 = 3 kg/tree; B2 = 6 Kg/tree; The dose of N,P,K fertilizer used consists of P0 = Without N, P, K Fertilizer (Control); P1 = 0,4 kg/tree urea (N), 0,19 kg /tree TSP (P), 0,67 kg/tree KCl (K); P2 = 0,8 kg/tree urea (N), 0,39 kg /tree TSP (P), 1,35kg/tree KCl (K). The results of this study indicated that coal fertilizer with a dose of 6 kg/tree had a very significant effect on the increase in the number of male flowers, female flowers, the increase in the number of fruit bunches and the weight of oil palm fruit bunches. The combination of coal fertilizer as much as 6 kg/tree and N,P,K fertilizer as much as 0,8 kg/tree urea (N), 0,39 kg/tree TSP (P), and 1,35 kg/tree KCl (K) can increase the weight of oil palm fruit bunches.
