Intsia bijuga (ipil, Caesalpiniaceae) stecklings (rooted stem cuttings) produced by rooting of stem cuttings were treated with Rhizobium sp. BJ118 and MYKOVAM either alone or in combination and with chemical fertilizers such as urea, ammonium phosphate and NPK (14-14-14). Results indicated that, treatments began to exert their physical and chemical effects on the stecklings only at 90 and 120 days after inoculation and variables affected include the following: shoot height (cm), root collar diameter (mm), shoot fresh weight (g), % organic matter, and % inorganic matter. However, treatments showed that significant effect on the % phosphorus and % nitrogen as early as 60 days after inoculation. The stecklings in the control treatment were always the shortest and with the narrowest root collar diameter, and with the lowest values of shoot fresh weight, % organic matter, % inorganic matter, % phosphorus and % nitrogen. To fully determine the effectiveness of the treatments, it is therefore worthy to look at the performance of the plants not only the nursery condition but also under field condition.
