Abstract

Liberica coffee is a type of coffee that can grow in soils with low pH and low nutrients. One of the efforts to increase the strength of the coffee seedling is by improving the planting media, through organic fertilizers and ameliorants application. This study aimed to analyze the effect of liquid organic fertilizer (LOF) and dolomite on the growth of Meranti Liberoid 2 (LIM 2) coffee seedlings. This research was conducted at the Pakuwon Experimental Station, Sukabumi, from April 2021 to January 2022. The research design used was a factorial 2 factor with 3 replications. The first factor was the LOF concentration (0, 5, and 10%), and the second was the dolomite dose (0- 2.5- 5.0- 7.5- and 10 g seedling-1). The results showed that the highest seedling height, leaf, and root dry weight of LIM 2 coffee seedlings was achieved by dolomite treatment of 7.5 g seedling-1 without LOF. The use of LOF can be an alternative to the need for dolomite to increase the growth of LIM 2 coffee seedlings.
