Survival and growth of rattan intercropped with coffee and cacao in the agroforests of Indonesia
This study investigated the intercropping of rattan, an important non-timber forestproduct, in coffee and cacao agroforests in Sulawesi, Indonesia. The viability of producingseedlings from seeds and vegetative cuttings with the large-diameter rattan, Calamus zollingeriBeccari, and initial seedling survival, growth and response to light and soil drainage wereinvestigated in village nurseries and perennial farms. Over 96% of seeds and 61% of vegeta-tive cuttings were raised to transplanting size (25 cm with two to three leaves) over 20 months.One hundred C. zollingeriseedlings produced from cuttings were transplanted into each ofthree coffee or cacao farms and one primary forest site and exhibited an overall survival rateof 96%, 12.7 cm of height growth and the production of 0.8 new leaves per plant after eightmonths. No significant differences were observed between the four sites with respect to seedlingsurvival, growth, or leaf production and no significant differences were found between seedlingsurvival, growth or leaf production and light intensity (based on multiple PAR measurements).However, poorly drained sites exhibited significantly reduced C. zollingeriseedling survival andgrowth. The cultivation of C. zollingerirattan in coffee and cacao agroforests represents apotential means of intensifying and diversifying perennial cash crop farming systems.
