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配置下伴生树种对阿拉比卡咖啡（Arabica coffee）产量及饮品感官品质的影响。本实验于2012年在巴西米纳斯吉拉斯州圣安东尼奥-杜安帕鲁市（Santo Antônio do Amparo）开展。实验采用完全随机区组设计（randomized complete block design），设置4次重复与7组处理，具体如下：单作模式下的卡特杜伊红果IAC 99品种阿拉比卡咖啡（种植规格3.40×0.65 m）；以及该品种分别与非洲桃花心木（Khaya ivorensis）、柚木（Tectona grandis）或粉雪松（Acrocarpus fraxinifolius）按两种咖啡行间距（9.0×13.6 m与18.0×13.6 m）进行间作。林间固定种植3行咖啡，林带总间距为13.6 m。分别于2017与2018收获季对咖啡的产量、感官分析（杯测试验）及感官属性含量进行测定。结果显示，处理因素与收获年份均对咖啡产量存在显著影响。2018年，与非洲桃花心木或柚木间作的咖啡感官评价结果为正向好评。感官属性与风味细微差异会因收获年份发生改变。无论伴生树种间距如何，与非洲桃花心木间作的阿拉比卡咖啡均表现出更优的产量水平，且在2018年收获季拥有更高的感官品质。
