Productivity and beverage sensory quality of arabica coffee intercropped with timber species

Abstract: The objective of this work was to evaluate the productivity and beverage sensory quality of arabica coffee under the influence of tree species cultivated at different spacings. The experiment was set in 2012, in the municipality of Santo Antônio do Amparo, in the state of Minas Gerais, Brazil. A randomized complete block design was carried out with four replicates and seven treatments, as follows: Catuaí Vermelho IAC 99 Coffea arabica in monoculture (3.40x0.65 m); and this cultivar intercropped at two spacings (9.0x13.6 and 18.0x13.6 m) in the coffee row ‒ either with African mahogany (Khaya ivorensis), teak (Tectona grandis), or pink cedar (Acrocarpus fraxinifolius). Three coffee rows were fixed between rows, totaling 13.6 m between the wooded rows. Productivity, sensory analysis (cup test), and content analysis of sensory attributes were evaluated in the 2017 and 2018 crop years. The treatments and years of harvest influenced productivity. The sensory analysis was positive for coffee intercropped with African mahogany and teak, in 2018. Sensory attributes and nuances are modified by the years of harvest. Arabica coffee plants intercropped with African mahogany show a superior productivity, regardless of the spacing between species, as well as a higher sensory quality in the 2018 harvest.

摘要：本研究旨在评估不同种植间距的伴生树种对阿拉比卡咖啡（Coffea arabica）的生产力与饮品感官品质的影响。实验于2012年在巴西米纳斯吉拉斯州圣安东尼奥杜安帕鲁市开展，采用随机完全区组设计（randomized complete block design），设置4次重复与7种处理方式，具体如下：单作的Catuaí Vermelho IAC 99阿拉比卡咖啡，种植间距为3.40×0.65米；该品种分别与非洲桃花心木（Khaya ivorensis）、柚木（Tectona grandis）或顶果木（Acrocarpus fraxinifolius）间作，咖啡行设置两种间距（9.0×13.6米与18.0×13.6米）。林带间固定种植3行咖啡，林带总间距为13.6米。分别于2017与2018作物年度对生产力、感官分析（杯测，cup test）及感官属性含量分析进行评估。结果表明，处理方式与收获年份均对咖啡生产力存在影响。2018年时，与非洲桃花心木和柚木间作的咖啡感官评价结果优异。感官属性与风味细微特征会随收获年份发生改变。无论伴生树种的种植间距如何，与非洲桃花心木间作的阿拉比卡咖啡植株均表现出更优的生产力，且在2018年收获季拥有更高的感官品质。
