Abstract

Arabica coffee (Coffea arabica L.) is one of the important plantation crop commodities in the Indonesian economy. Plant spacing in coffee plants greatly affects the growth and productivity of coffee plants. The application of appropriate coffee plant spacing can reduce competition for nutrients in each plant, so that it can affect the production of coffee plants, the distance of coffee plants that are too narrow can inhibit the photosynthesis process of plants because the light received by some leaves is less due to the blockage of light by the leaves of other coffee plants. The quality of Arabica coffee plants is more sensitive to pests and diseases than Robusta coffee and requires more special care, besides the use of spacing can minimise or accelerate the spread of leaf rust disease (Hemileia vastatrix) between coffee plants, Hemileia vastatrix is a fungus that is an obligate parasite, which means that the fungus cannot live on abiotic tissues, this spread is due to the microclimate created by the spacing applied if it is too narrow then the spread of the disease will be faster than with a wider spacing. The development of leaf rust disease (Hemileia vastatrix) intensity can be influenced by the use of coffee plant spacing. Greater spacing helps minimise direct contact between plants and reduce the spread of disease. This study aims to obtain the best planting distance to increase production yields in coffee plants and reduce the intensity of leaf rust disease (Hemileia vastatrix). This research was conducted in Alamendah Village, Rancabali, Ciwidey with a garden altitude of 1,800 metres above sea level with a plant age of 4 years, the research was conducted in April - June 2024. The research used a Randomised Group Design (RAK) with 9 replications and 3 treatments of coffee plant spacing as treatments, namely: 2 m x 2 m, 2.25 m x 2.25 m and 3 m x 3 m. The results showed that there was an effect of coffee plant spacing. The results showed that there was an effect of planting distance on the yield of coffee plants, but no effect on the intensity of leaf rust disease attack (Hemileia vastatrix). The best planting distance for coffee plant yield is the planting distance of 3 m x 3 m. Keywords: Spacing, Arabica Coffee, Leaf Rust, Hemileia vastatrix
