STRESZCZENIE
The efficiency of phosphorus uptake by plants in an Ultisol soil is very low because most of soil phosphorus is precipitated by Al and Fe. Oil palm empty fruit bunches can be used as basic materials of biochar and compost, and as sources of isolates of phosphate solubilizing fungi. This study was aimed to elucidate the effect of application of phosphate solubilizing fungi with biochar and compost generated from oil palm empty fruit bunches on growth and yield of maize an Ultisol of Central Kalimantan. This study consisted of two experiments. The first experiment was inoculation of four isolates of phosphate solubilizing fungi isolated from of oil palm empty fruit bunches, i.e. Acremonium (TB1), Aspergillus (TM7), Hymenella (TM1) and Neosartorya (TM8) to 'biocom' media (mixture of biochar and compost generated from oil palm empty fruit bunches) to obtain phosphate solubilizing fungi that can adapt to the media. In the second experiment, the best results in the first experiment were applied to an Ultisol soil planted with maize. The results showed that isolates that were best adapted to biocom media were Aspergillus-TB7 with 60:40 proportion (60% biochar + 40% compost) and Neosartorya-TM8 with 70:30 proportions (60% biochar + 40% compost). The application of the first experiment results to the second experiment showed that the application of biocom plus Neosartorya-TM8 (BTM) on an Ultisol soil significantly improved growth and yield of maize, as well as phosphorus uptake and efficiency of phosphorus uptake by maize.
