Pengaruh Naungan Sengon (Falcataria moluccana L.) dan Pemupukan terhadap Pertumbuhan Ganyong Putih (Canna edulis Ker.)

Abstract

Sengon (Falcataria moluccana L.) public forests still becoming custom by Monoculture system. Alternative solution to optimalize the use of land is by agroforestry system. Agroforestry system give income benefits that non timber product. This research is shading influence of sengon and fertilization against white ganyong growth (Canna edulis Ker.). The shading treatments consist of the open area (shade intensity 0%) and sengon shaded area (shade intensity 42%). The fertilizer treatments consist O0 (no fertilizer as control), O1 (POC 350 mL/ha, 450 mL/ha), O2 (POC 700 mL/ha, 900 mL/ha), O3 (POC 1400 mL/ha, 1800 mL/ha) and NPK. The experiment by nested design. The results showed that growth of white ganyong on sengon shaded area is higher than open area to parameters hight of plant, length of leaves, width of leaves and plant biomass. Treatments of shading and fertilization did not significantly effect to tuber wights of white ganyong.
