Effect of Intercropping and Fertilizer on Growth Performance of Bamboo (Gigantochloa brang)
Agroforestry is one of the agricultural approaches that integrates the woody perennial and agricultural crop. Bamboo is one of the suitable perennial species for agroforestry practices because of its various uses and fast-growing botanical species. This study was conducted to define the best crop for integrating with Gigantochloa brang bamboo species and to determine the best fertilizer regime which produce highest growth performance for Gigantochloa brang. Three different plots were established that are; a) G. brang integrated with Musa paradisiaca L., b) G. brang integrated with Orthosiphon stamineus B., and c) consisting of only G. brang (control). The G. brang were planted with 4 m x 4 m planting distance while the M. paradisiaca and O. stamineus were planted in between of G. brang rows. Two types of fertilizer (chicken dung and nitrophoska) with four different rates were applied at G. brang clump for the analysis of fertilizer regime. Results indicate that G. brang integrated with O. stamineus gave the highest growth for number of culms, DBH, and height of shoot compared with another plot including the control plot. For the fertilizer’s application, there were significantly different on all parameter, but further analysis of different fertilizer rates indicates that only two parameters (number of culm and DBH) were found significantly different (p<0.01) In conclusion, O. stamineus is the most suitable crop to integrate with G. brang and the application of 0.5 kg nitrophoska was the best rate of fertilizer applied to produce the highest growth for G. brang bamboo species.
