Effect of crop pattern and types of manure on the growth of Sappan wood (Caesalpinia Sappan L.) in Jatinangor, West Java, Indonesia

Abstract

 Sappan wood plants are one of the medicinal plants in Indonesia. Considering the potential of Sappan wood plants in the health and industrial sectors, special cultivation techniques are required to ensure that Sappan wood plants can grow with a large stem diameter. A large stem diameter can be achieved by using the appropriate planting distance. The right planting distance requires land with sufficient organic content. This research aims to determine the optimum planting distance and the appropriate type of organic material to produce Sappan wood plants with a large diameter. The experimental design used was a Split Plot Design, with planting distance (J) as the main plot and organic fertilizer (P) as the sub-plot. The planting distance factor levels were J1 = 1m x 1m, J2 = 2mx2m cm, J3 = 3m x3m. The organic fertilizer factor levels were P1 = Cow Manure Fertilizer, P2 = Chicken Manure Fertilizer, and P3 = Sheep Manure Fertilizer. The results showed an interaction between the planting distance treatment and the use of manure fertilizer on the parameters of stem diameter and soil pH of Sappan wood plants at 3 MAP (months after planting). The planting distance treatment independently influenced the results, with a 1m x 1m planting distance providing the best results for plant height and stem diameter. In general, the application of different types of manure did not significantly affect the growth of Sappan wood plants.
