“…Canopy dimension plays an important role in plant growth since the photosynthesis process mainly occurs in this part of the plant (Cavalli and Finger 2016), which eventually affects tree biomass productivity (Goodman et al 2014). The canopy area is also a good indicator regarding the use and requirement of growth space (Pretzsch et al 2015).…”

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

“…8). The process of photosynthesis that increases the productivity of a plant is determined mainly by the quality of the plant canopy (Cavalli and Finger 2016;Pretzsch et al 2015;Sadono et al 2015). The research area has a pH of 5.9, an average temperature of 28.63°C, and average relative humidity of 72.67%.…”

Agroforestry is a forestry and agriculture plant utilization system using sustainable land management to gain more products. Falcataria moluccana is a forestry plant that has been cultivated mostly in an agroforestry system by the Indonesian people, particularly on Java Island. Appropriate F. moluccana species selection and planting space in an agroforestry system are expected to improve plant growth and suppress the damage level that occurred in F. moluccana. The agroforestry system with F. moluccana and rice plant (Oryza sativa) is one of the alternative ways to support the national food needs. This study aimed to analyze the growth of various provenances of F. moluccana at the age of 14 months and analyze the productivity of IPB 3S rice in two planting spaces of F. moluccana. This study used a completely randomized two-factorial design, with the first factor being the provenance of F. moluccana, i.e., Solomon F1, Solomon F2, and local Kendal, and the F. moluccana spacing of 1.5 m x 3.0 m and 1.5 m x 1.5 m was the second factor. The F. moluccana growth parameters, rice plant growth parameters, and rice plant productivity in agroforestry systems were analyzed using an analysis of variance (ANOVA). If a significant effect on each parameter at a 5% confidence level occurred, the parameters were further analyzed with Duncan’s Multiple Range Test (DMRT). The study found that provenance had no significant effect on the growth of 14-month-old F. moluccana. The results also showed that the growth of 14-month-old Solomon F2 had a relatively higher value on the parameters of height and diameter. The highest productivity of IPB 3S rice was found in the local F. moluccana shade at a spacing of 1.5 m x 1.5 m, reaching 0.201 tons/ha. The highest rice productivity was due to the magnitude of the light intensity received by rice of 5414.30 lux.

“…The crown condition is an important parameter to be assessed because it is the place for photosynthesis. The photosynthesis results are distributed for the growth of the plant (Cavalli and Finger 2017). The canopy also reflects a close relationship with tree health because it has a function in maintaining the balance of energy regulation from sunlight, distributing rainwater, and retaining moisture in the forest.…”

Urban forests have a high intensity of exposure from external factors such as air pollution and human activity disturbances. As a result, fallen trees and tree defects often occurred and can endanger the people around the city. This study aimed to assess tree health in Cianjur Urban Forest and formulate tree health management strategies. The tree health assessment used the Forest Health Monitoring (FHM) method. The management strategy was formulated using the Strengths, Weaknesses, Opportunities, and Threats (SWOT) Matrix and Quantitative Strategic Planning Matrix (QSPM). Tree sampling using FHM plots determined about 534 trees from 30 species. The results showed that Cianjur Urban Forest had high land productivity and biodiversity. The canopy condition was 86.41% in good condition. The results revealed that 92.70%, 5.34%, 1.31%, and 0.56% of the trees were in healthy, lightly, moderately, and heavily damaged conditions, respectively. The tree species that suffered the most damage was Acacia denticulosa. The most types of tree damage were leaf damage and rotten wood. Cianjur Urban Forest benefits the community as a place for natural tourism, sports, education, and expand job opportunities. However, the management of Cianjur Urban Forest has not been implemented effectively. There are three priority strategies to improve tree health management in Cianjur Urban Forest, i.e., conducting the assessment, evaluation, and action on damaged trees, community cooperation, institutional strengthening development programs, and optimizing collaboration and government commitment with managers.Keywords: Forest Health Monitoring, SWOT analysis, QSPM matrix, urban forest
