Oil palm (Elaeis guineensis Jacq.) holds a very strategic role in the Indonesia economy. Plants that have reached the economical age of 25 years need to be replanted using qualified oil palm seedling. The qualified seedling is obtained through proper fertilization. The combination of NPK fertilizer and organic material of oil palm empty fruit bunches (OPEFB) which has been given a cellulolytic bacterial consortium can provide sufficient nutrients for the growth of oil palm seedlings. The study aimed to determine the effect of giving a combination of OPEFB organic material, cellulolytic bacterial consortium, and NPK fertilizer on the growth of oil palm seedling (Elaeis guineensis Jacq.) at main nursery. This experiment used a single factor experiment arranged in a Completely Randomized Design (CRD). The treatments were a 100% NPK, a OPEFB compost, a 50% NPK + OPEFB compost, a 50% NPK + OPEFB + Cellulolytic bacterial consortium, and a OPEFB + cellulolytic bacterial consortium. The results showed that the application of inorganic fertilizers combined with organic fertilizers (a OPEFB compost and a OPEFB + cellulolytic bacterial consortium) had a good effect on each parameter. Giving organic fertilizer without inorganic fertilizer had not affected plant growth on all parameters. Application of a OPEFB compost and a OPEFB + cellulolytic bacterial consortium can reduce the use of inorganic fertilizers by 50%.

Nursery success is one of the important things in the oil palm plantation business. Nurseries are the beginning of efforts to cultivate palm plants, so the nurseries must consider all the conditions that can affect the development of the growth of oil palm plants. One important requirement is to conduct nurseries that tend to be organic, which are environmentally friendly. The use of organic fertilizers and sustainable biological fertilizers is very important in increasing soil fertility, growth and crop yields. Organic fertilizer that used is sugar mill wasted blotong and biological fertilizer is mychorrhizal. To determine the effect of giving sugar mill waste blotong and mycorrhizal applications on P nutrient levels in the Main Nursery. This study uses factorial randomized block design method (RAK). First factor is blotong (B): B0= control, B1= 500 gr blotong/seed, B2= 100 gr blotong/seed. Second factor is Mycorrhizal (M): M0= control, M1= 10 gr mycorrhizal arbusculae/seed, M2= 20 gr mycorrhizal arbusculae/seed. 9 treatment combinations were obtained with 4 replications, so the total treatment was 36. Blotong compost application significantly affected palm seed height, canopy dry weight and root dry weight, while mycorrhizal application only significantly affected seed height. the combination between them two gives the best effect on B1M1 treatment.
