Study on the Growth of Falcataria moluccana at 14-Month-Old and the Productivity Rice Plant (Oryza sativa) IPB 3S in Agroforestry System

Abstract

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.

Slow-release Fertilizer Application on Silk (Falcataria moluccana Miq.) and Rice (Oryza sativa L.) Plant Growth and Yield in Agroforestry System

“…This leads to reduced carbon absorption by plants until, finally, the process and results of photosynthesis (photosynthate) cannot meet the needs of plants (Taylor et al (2022). Similar research findings regarding competition for sunlight in agroforestry systems were documented by several studies, including Hairmansis et al (2017), Muhidin et al (2018), Ikhfan and Wijayanto (2019), Satriawan et al (2022), andBriliawan (2022).…”

“…Upland rice planted at a smaller distance with sengon is hampered by its growth because the sengon canopy is large and dense, so sunlight does not reach the rice. In their study on sengon and rice agroforestry, Wijayanto and Briliawan (2022) discovered that a dense planting distance (1.5 × 1.5 m) led to lower grain weight and fewer productive tillers in rice compared to those planted with a wider distance (3.0 × 1.5 m). The reduction in the number of tillers is caused by the necessary photosynthate input that cannot meet the needs of plants for the growth of rice tillers evenly (Lestari et al 2020).…”

Planting patterns in rubber agroforestry (Hevea brasiliensis) developed by the communities of Menggala Mas Village, Lampung Province, Indonesia

“…Rubber-based agroforestry is an agricultural practice that aims to slow the loss of soil organic matter and reduce the volume of water runoff (Zhu et al 2018). The spacing of trees in a rubber agroforestry system must be appropriate to control competition for light and nutrients (Wijayanto and Briliawan 2022). The planting distance for rubber monoculture is usually 4 × 5 m and for agroforestry is 3 × 6 m.…”

Time Consumption and Productivity of Motorbike Timber Extraction in Private Forests

“…The types of plants developed in private forests consist of forestry plants, multi-purpose tree species, plantation plants, and agricultural plants (Oktaviyani et al 2017). One species of forestry plant that is most widely planted in private forests in Indonesia is sengon (Falcataria mollucana) (Wijayanto and Briliawan 2022;Wijayanto and Tsaniya 2022). The need-cutting system is a common harvesting system applied in private forests (Nugroho et al 2017).…”
