“…Since all the coffee cherries from all production systems were subjected to the same processing method (wet processing method which contribute to best color and shape and make of coffee bean), the observed variation could be due to the botanical variability or growth environment. Davis et al (2011) also confirmed that the green bean color was best where the mucilage had removed by fermentation under water in wet processing and the poorest color was obtained when the bean dried inside the fruit.…”

A B S T R A C T In Ethiopia, coffee production system can mainly be categorized as; garden, plantation, semi-forest and forest coffee production systems which are assumed to vary in the intensity of management. But, little is known whether these production systems and the associated management practices have effect on coffee beans abnormalities. Besides, the role of pea berry on cup quality parameters has not been documented under Ethiopian condition. Therefore, the study was carried out to assess the influence of coffee production systems on the occurrence of bean abnormality and cup quality. The study was carried out in the landscape matrix of forest and agricultural lands near Jimma, in South-western Ethiopia. A total of 24 study sites in four production systems were sampled. Coffee cherries were prepared following the standard procedure for wet method of processing. The beans sensory quality was tested with and without pea berry (the major bean abnormality observed in this study). Coffee production system showed significant influence on the occurrence of bean abnormality. Plantation coffee production system showed significantly higher proportion of pea berry which accounts for higher portion of bean abnormality than the rest of production systems (p<0.001). There was no significant difference between the coffee beans tested with and without pea berry in all of the production systems except body in the garden coffee production system, where the coffee tested with pea berry gave the lower grade while coffee tested without pea berry scored the highest grade. In conclusion, an evidence was not generated for the negative effect of pea berry on coffee quality. However, future study was recommended on the causes of bean abnormalities in coffee across coffee production systems as occurrence of pea berry may have yield implication.

“…O gênero Coffea é representado por mais de 120 espécies, destacando-se comercialmente as espécies: Coffea arabica e C. canephora (DAVIS et al, 2011). A produção média mundial do café nos últimos anos foi superior a 140 milhões de sacas, produzido principalmente, nos países considerados em desenvolvimento (ICO, 2013).…”

ResumoObjetivou-se avaliar a taxa de crescimento vegetativo de plantas de Coffea arabica sob diferentes regimes hídricos, bem como relacioná-la com os fatores climáticos, tendo como base o crescimento sazonal de grupos de ramos ortotrópicos e plagiotrópicos de diferentes idades, na região do Cerrado Goiano. O experimento foi instalado em delineamento de blocos casualizados, com quatro repetições e 12 plantas por parcela. A área de estudo foi dividida em três tratamentos: plantas irrigadas por gotejamento, plantas com deficiência hídrica por 30 dias na época seca e plantas não irrigadas o ano todo. Foram utilizadas plantas com sete anos de idade, cultivadas a pleno sol, no espaçamento de 2 m entre fileiras e 0,9 m entre plantas. As condições climáticas (temperatura do ar, precipitação e umidade relativa do ar) influenciaram a taxa de crescimento dos ramos ortotrópicos e plagiotrópicos da espécie C. arabica. Todos os ramos avaliados apresentaram crescimento sazonal semelhante, de modo que os ramos plagiotrópicos apresentaram taxas de crescimento diferenciada no mesmo período do ano. Sob temperaturas mínimas do ar abaixo de 17 ºC e deficiência hídrica, a taxa de crescimento dos ramos de C. arabica foi reduzida. Deficiência hídrica de 30 dias não prejudicou de forma significativa o crescimento de ramos no cafeeiro arábica; contudo, em plantas não irrigadas observou-se redução do crescimento dos ramos. Palavras-chave: Café, estresse hídrico, adaptação, temperatura do ar AbstractThe aim of this work was to evaluate the vegetative growth rate of coffee plants (Coffea arabica L.) and its relation with climate variables on the Cerrado of Goiás State, Brazil, based on the seasonal growth of orthotropic and plagiotropic branches with different ages in coffee trees under irrigation, water deficit and without irrigation. The experiment was carried out in a completely randomized block design with four replications and 12 plants per plot. The experimental area was divided in three treatments: plants with drip irrigation and without irrigation and submitted to water deficit for 30 days during the dry season. The experiment was carried out with plants of seven years old growing under full sun and spacing 2 m between rows and 0.90 m between plants within row. The climate variables (air temperature, precipitation and relative humidity) affected on a seasonal way the vegetative growth rate of orthotropic and the group of 1º plagiotropic branches of C arabica. All evaluated branches showed similar seasonal growth, and the 1º plagiotropic branches showed different growth rates in the same

“…The genus Coffea comprises at least 124 species, of which Coffea arabica and C. canephora are economically important (Davis, Tosh, Ruch, & Fay, 2011). Despite C. arabica being the most widely farmed species in the world, the cultivation of C. canephora (Conilon coffee) has significantly contributed to coffee production worldwide.…”

ABSTRACT. Extreme temperatures and persistent water stress stand out among the main factors that restrict the vegetative growth and productivity of Coffea canephora. The objective of this study was to evaluate the vegetative growth of orthotropic and plagiotropic branches of C. canephora under non-irrigated and irrigated conditions, and their correlation with climatic factors in the Atlantic region of Bahia State, Brazil. The experiment was established with two treatments (non-irrigated and irrigated) in a completely random design with 14 replicates. One orthotropic and four plagiotropic branches were labelled on each plant. During the two-year experimental period, the growth of these branches was evaluated at 14-day intervals. Two harvests were performed to obtain productivity data. In summary, it was confirmed that irrigation resulted in an increased productivity of Conilon coffee in the Atlantic region of Bahia, Brazil. The growth rate of the orthotropic and plagiotropic branches was higher in irrigated plants. The growth rate of the plagiotropic branches was limited by the fruit load capacity. The growth rate of C. canephora branches was not limited by the minimum average air temperature in the Atlantic region of Bahia, Brazil.Keywords: Coffea canephora, water deficit, temperature, plagiotropic branches. RESUMO.Temperaturas extremas e o deficit hídrico prolongado destacam-se como os fatores limitantes ao crescimento vegetativo e à produtividade de Coffea canephora. O objetivo foi avaliar o crescimento vegetativo de ramos ortotrópicos e plagiotrópicos de C. canephora em condições não irrigadas e irrigadas, e relacioná-lo com os fatores climáticos, na região Atlântica da Bahia. O experimento foi instalado com dois tratamentos (não irrigado e irrigado), no delineamento inteiramente casualizado, com 14 repetições. Marcou-se um ramo ortotrópico e quatro ramos plagiotrópicos em cada planta. O crescimento desses ramos foi avaliado em intervalos de 14 dias, durante dois anos. Foram realizadas duas colheitas para obtenção da produtividade. Em resumo, foi confirmado que a irrigação resultou em aumento de produtividade de café Conilon na região Atlântica da Bahia. A taxa de crescimento dos ramos ortotrópicos e plagiotrópicos com carga pendente é superior nas plantas irrigadas. A taxa de crescimento de ramos plagiotrópicos é limitada pela carga pendente. A taxa de crescimento dos ramos de C. canephora não é limitada pela temperatura mínima média do ar predominante na região Atlântica da Bahia. Palavras-chave:Coffea canephora, deficit hídrico, temperatura, ramos plagiotrópicos.
