Estimated Yield Potential of Robusta Coffee (Coffea canephora Pierre ex A. Froehner) at Bogor District

Abstract

Bogor District is one of the Robusta coffee (Coffea canephora Pierre ex A. Froehner) producing areas in West Java. To estimate crop yield of Robusta coffee, planters usually count the amount of a given crop harvested in a sample area. Then the harvested crop is weighed, and the crop yield of the entire field is extrapolated from the sample. Recently by utilizing the geographic information system (GIS) used to determine the level of regional suitability combining with land productivity. It will help in analysing, planing and taking various policy for development Robusta coffee. This study aimed to estimate of yield potential of Robusta coffee. This research was conducted from November to December 2020 at Bogor District. The land suitability class for Robusta coffee in Bogor which was in the moderately suitable (S2) class of around 2% (5,227.78 ha), marginal (S3) 33% (99,189.20 ha) and not suitable (N) 65% (194,808.40 ha). The yield potential of Robusta coffee is obtained 105,030,473.1 kg or 105,030.47 tons. The highest yield potential of Robusta coffee is in Cigudeg and Sukamakmur subdistricts.
