Growth of three types of sengon (Paraserianthes spp.) in varying planting spaces in agroforestry system

Abstract. Sopacua F, Wijayanto N, Wirnas D. 2021. Growth of three types sengon (Paraserianthes spp.) in varying planting spaces agroforestry system. Biodiversitas 22: 4423-4430. Sengon is a fast-growing tree species that commonly cultivated the system by communities Indonesia, mainly on Java Island. Among several sengon, Solomon currently gaining popularity due to fast growth height and stem diameter. Nonetheless, spacing layout selected unclear, including which yields more optimal growth. This study aimed examine (i.e., F2, F1, local Kendal) patterns, namely 1.5x1.5m, 3x1.5m, 3x3m. research was conducted from October 2019 January 2020 (three months) Cikabayan Forest, Bogor Agricultural University, Bogor, West Java. The parameters observed were plant height, rate, diameter, diameter volume, canopy area. Data analysis performed using ANOVA continued with Duncan's. results showed all had at various spacings. F2 adapted well denser spacings (1.5x1.5m 1.5x3m) highest averages area ??10.50 m, 8.65 cm, 0.36 m3, 5.39 m2. Local Kendal wider (3x3m) average ??8.96 0.043 1063 While F1 rate ??10.05 1.54 8.59 0.042 m2, 2075.30 In general, it can be concluded adapt narrow distances or wide distances. recommended planted narrower distance get
