Study on the amount of chlorophyll content and leaf area of Robusta coffee plants with shade trees and fertilizer application in Hanakau Sukau West Lampung

Abstract

Coffee is one of the most important plantation crops in Indonesia. Coffee has high economic value, significantly increasing income, especially in West Lampung district, Lampung province. Coffee production in this area reaches 954 kg ha. Some subdistricts can produce more than 1,000 kg ha-1 year -1, and some have only reached 500 kg ha-1 year -1 This research was conducted from June to November 2020, to get the effect of shade plants and the effect of types of fertilizers on the productivity of robusta coffee and their interaction on robusta coffee production. The results showed that the amount of chlorophyll content of robusta coffee leaves was not influenced by shade and fertilization, and the interaction between fertilization and shade trees had an effect on leaf surface area.

Application of Compost and Manure in the Biopore Infiltration Hole to Improve Saturated Hydraulic Conductivity (Shc) of Soil in the Coffee Root Zone

“…This affects the metabolic process of the coffee plant as evidenced by the increase in leaf chlorophyll content (Figure 2.) so that the photosynthesis process will run optimally and coffee beans yield will increase (Adugna D Bote & Struik, 2011;Chemura et al, 2017;Mayoli & Gitau, 2012;Netto et al, 2005;Reis et al, 2009;Sudirman & Hartono, 2020).…”
