Response of Ficus variegata seedling size on their early growth in imperata grassland

Abstract

Ficus variegata is pioneer species that provides pulp raw materials, soil water protection, beehives tree, animal fodder, and medicinal plants. Introduction of F. variegata seedling at Imperata grassland constrained with low plant survival which caused by stressed plants and stagnant growth. The objective of this research was to determine the effect of five F. variegata seedlings size on the initial growth at Imperata grassland. The research was used Randomized Complete Block Design, with 5 seedling sizes for the treatment, there are size A (seedling height 15-50 cm), size B (51-75 cm), size C (76-100 cm), size D (101-125 cm), and size E (126-150 cm). In this research, we observe some parameters like height and stem diameter increment, canopy width, and plant survival at 1, 6, and 12 months old. Different seedling size has a very significant effect at six months old and very significant effect at 12 months old on the height, diameter and width crown increment. Seedling size 15-50 cm has shown faster height growth but has lower survival than another size in the dry season. For rehabilitation Imperata grassland, it is recommended using seedling size 50-125 cm because more adaptive and shown better growth in all parameters.

The Changes in Seed Germination Capacity, Seedling Growth, and Leaf Morphology of Ficus variegata Blume Influenced by Gamma-Ray Irradiation

“…Another benefit of nyawai is that its edible fruit contains high nutrients (Shi et al 2014) and antibacterial and antioxidant compounds (Leonita et al 2015;Rusli et al 2019). The species is also very suitable for reforestation and revegetation of degraded land because it can grow on various soil types and survive in Imperata grassland areas (Wahyuningtyas et al 2022).…”
