“…In this study, seedlings grown on mixed media had higher growth height and diameter for the three species tested. Mixed media was a mixture of several organic materials such as soil, compost rice husk charcoal, and lime so that the fertility rate was better [18,30]. Inoculation of AMF has been revealed to improve productivity in low-fertility soils [31].…”

Seedling growth in the nursery and early field performance of three fast-growing tree species from the Rubiaceae family, i.e., white jabon (Neolamarckia cadamba), red jabon (Neolamarckia macrophylla, and gempol (Nauclea orientalis), were tested by using different seedling media and arbuscular mycorrhizal fungi (AMF) treatments in the nursery and mixed-species field tests. The experiment design in the nursery and field test was laid out following a split-split plot design of a randomized complete block with four replications. The main factors were tree species, the sub-factors were seedling media, and the sub-sub factors consisted of the AMF inoculation, with a mixed species planting pattern. White jabon had a more dominant growth both at the seedling level in the nursery and at the field test level until the age of 2 years, followed by gempol and red jabon. AMF inoculation in those three species at the seedling level was strongly influenced by the characteristics of the seedling media like media with high fertility levels resulting in a very low percentage of AMF colonization. In the field trial, all tree species and treatments were infected with mycorrhizae with colonization percentages ranging from 27.6% to 57.7%, which was suspected to be an infection from native AMF in the planting site. The AMF application had a significant effect on the percentage of colonization and tree diameter growth of 2-year-olds with a percentage increase of 14.4% and 8.4%, respectively.

“…Adanya keterbatasan regenerasi alami dan penanaman konvensional dalam mengembalikan fungsi dan keberadaan hutan membutuhkan metode lain yang dapat dijadikan alternatif rehabilitasi lahan dan hutan (Holbert, Sudrajat, Nurhasybi, & Yulianti, 2019;Sudrajat & Rustam, 2020). Regenerasi alami mengalami kesulitan karena pada lahanlahan yang kritis sulit untuk ditemukan pohonpohon yang mampu menghasilkan benih dengan kualitas dan kuantitas yang memadai (Graham & Page, 2018) dan memerlukan waktu yang lambat untuk membentuk kanopi yang mampu menutupi lahan (Blackham, Webb, & Corlett, 2014).…”

Critical land, which is still very large requires alternative reforestation methods, one of which is direct seeding. This study aims to determine the seed treatment and land preparation in direct seeding of A. crassicarpa seeds. The research was conducted in Parungpanjang, Bogor with a three-factor factorial randomized design, i.e. environmental conditions (A1=under the stand, A2=open area), seed treatment (B1=untreated, B2=soaked in hot water and allowed to cool for 24 hours), and sowing technique (C1=sowing on the soil surface without cleaning, C2=sowing on the soil surface of the cleared and loosened land, C3=sowing with 2-3 cm immerses on the cleared and loosened land). The results showed that seedlings under the stand tended to have better height growth (14.8 cm) compared to seedlings in open area (11.2 cm), as well as for seedlings diameter (under the stand 0.14 cm; in open area 0.11 cm). The application of the direct seeding of A. crassicarpa can be done by treating the seeds soaked in hot water allowed to cool for 24 hours and sowing methods by loosening the soil and immersing the seed 2-3 cm which results in 11% seedling survival, 11.85 cm height, and diameter 0.12 cm at 14 weeks after sowing.

“…The development of reforestation methods or practices continues to be pursued in many countries to accelerate the planting program of some critical forests. Operationally, containerized seedling is widely used in many countries, including Indonesia, for various planting programs [2]. Another reforestation method that is widely developed in temperate regions is bare-root seedling [3].…”

Possibility of bare-root seedling application for tropical forest and landscape restoration: A study on Gmelina arborea and Calophyllum inophyllum

Container and bare-root seedlings are the two basic stock types used in reforestation programs in many countries, but in the tropics, bare-root seedlings have never been widely applied. The objective of this research was to assess the possibility of bare-root seedlings for tropical forest and landscape restoration treated by fertilization in the nursery and aquasorb treatment using two forest tree species, i.e., Calophyllum inophyllum and Gmelina arborea. A randomized block design was used to assess the seedling performance in nursery and aquasorb application on bare-root seedlings and container (polybag) seedlings as a comparison. This research indicated that NPK fertilization in the nursery was able to increase the seedling growth of C. inophyllum and G. arborea. In the field test, polybag seedlings had better survival and growth than bare-root seedlings. The best survival and growth in both species were shown by the polybag seedling with fertilization and aquasorb treatment. The treatment also increased the bare-root seedling growth in both species. Bare-root seedlings of C. calophyllum resulted in higher seedling survival than bare-root seedlings of G. arborea. The application of bare-root seedling on C. inophyllum is more prospective to be applied in the tropics.
