<br/><br/> lpil, lntsia bijuga (Colebr.) 0. Kuntze, is an extraordinary valued tree<br/>highly targeted for intensive illegal logging and consequently categorized as<br/>an endangered species needing immediate protection and conservation<br/>interventions. The aim of this study is to determine cost- effective techniques<br/>in the mass propagation of hard-to-reproduce species, for conservation and<br/>production purposes. A 2x6 factorial experiment in Split-plot design was laid<br/>out with twelve (12) treatment combinations replicated three (3) times. There<br/>were two (2) methods of propagation (misting and non-misting) as the main<br/>plot and six (6) levels of concentration of IBA as subplots (0 ppm, 300 ppm,<br/>500 ppm, 1000 ppm, 1500 ppm and 2000 ppm). The observational study<br/>period is three (3) months.<br/>The result shows that there was no significant difference observed<br/>between the two methods of propagation with regards to length of roots. No<br/>significant difference was also shown for the interaction effects among<br/>methods of reproduction and levels of concentration. However, significant<br/>difference was observed among the levels of concentration where the highest<br/>length of roots was noted in the control (10.36 cm) cuttings. This was closely<br/>followed by the concentration 300 ppm (9. 70 cm). The least among the<br/>treatment was noted from 2000 ppm (7.74 cm). On the number of roots, the<br/>most number was recorded from 2000 ppm (12.83) while the control cuttings<br/>had the least with 2.50. On the rooting percentage, the treatment combination<br/>between methods of propagation and levels concentration showed significant<br/>difference. The non-misting propagation combined with B3 (300 ppm IBA) and<br/>B, (1000 ppm IBA) produced the highest percentage of roots with 100% and<br/>was followed by the group of 500 ppm IBA (93%). The lowest percentage of<br/>roots was noted in the misting method at 300 ppm IBA concentration (30%).<br/>On the root biomass, methods of propagation exhibited a significant<br/>difference. The ion-misting method had the higher root biomass at 1.98 g as<br/>compared to misting with 0.51g . lt was concluded that the application of<br/>IBA can work either alone or combination. It significantly accelerated the<br/>number of root formation of the length of roots, and the root biomass per<br/>cutting. The study infers that the length of roots and the number of roots<br/>formed were significantly influenced by the levels of IBA concentration, while<br/>root biomass was higher at non-mist propagation system. Furthermore,<br/>rooting percentage had a significant difference on the interaction between<br/>methods of propagation and levels of IBA concentration. Moreover, the lpil<br/>stem cuttings can be propagated through either of the methods. As a<br/>recommendation, /. bijuga can be best propagated generally with the more<br/>economical technique of mass propagation using non-misting with or without<br/>exogenous rooting hormone treatment.
