“…However, the irrigated plants exhibited the highest rates of vegetative growth compared with the non-irrigated plants during the various evaluations periods. Similar results were reported by Nazareno et al (2003), Carvalho et al (2006), Ferreira et al (2013) and Sakai et al (2015) for C. arabica.…”

“…Consequently, the farming of Conilon coffee has been conducted predominantly under irrigation because this condition enhances the production of flower buds (Carvalho, Colombo, Scalco, & Morais, 2006), increases the number of plagiotropic branches per plant (Nazareno et al, 2003), enhances the number of flowers per plant (Massarirambi, Chingwara, & Shongwe, 2009) and results in better development and grain formation (Pezzopane, Castro, Pezzopane, Bonomo, & Saraiva, 2010). Therefore, irrigation guarantees high productivity (Bonomo et al, 2013;Sakai et al, 2015) and a final product with a better beverage quality (Fernandes, Partelli, Bonomo, & Golynski et al, 2012).…”

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.

“…O aumento linear em altura com o adensamento das linhas também foi observado por Martinez et al (2007), Carvalho et al (2006a) e Melo et al (2005), que, em trabalhos semelhantes, concluíram que a redução do espaçamento entre as linhas de cultivo tende a aumentar a competição por luz, o que provoca maior crescimento ou estiolamento do ramo ortotrópico.…”

Resumo -O objetivo deste trabalho foi avaliar as consequências da redução no espaçamento entre linhas e entre plantas na linha de plantio sobre o crescimento, a produtividade e a bienalidade de produção do cafeeiro (Coffea arabica). Utilizou-se o delineamento experimental de blocos ao acaso, com três repetições, em esquema fatorial 4x3. Foram utilizadas quatro distâncias entre as linhas (2,0, 2,5 3,0 e 3,5 m) e três distâncias entre as plantas na linha de plantio (0,50, 0,75 e 1,00 m), o que totalizou 12 tratamentos. A produtividade e a produção por planta foram avaliadas anualmente entre 1994 e 2001, e o crescimento foi avaliado em 2002. A redução no espaçamento entre as linhas e entre as plantas na linha de plantio aumenta a produtividade da lavoura cafeeira. Os espaçamentos entre as linhas e entre as plantas influenciam o crescimento e a arquitetura dos cafeeiros.Termos para indexação: Coffea arabica, adensamento, manejo, fenologia. Growth, productivity and bienniality of coffee plants according to cultivation spacingAbstract -The objective of this work was to evaluate the consequences of spacing reduction between rows and between plants in the planting row on growth, productivity and bienniality of coffee plants (Coffea arábica). The experimental design was a randomized complete block, with three replicates, in a 4x3 factorial arrangement. Four distances between rows (2.0, 2.5, 3.0 and 3.5 m) and three distances between plants in the planting rows (0.50, 0.75 and 1.00 m) were used, which totalized 12 treatments. The productivity and the production per plant were assessed annually between 1994 and 2001, and the growth was evaluated in 2002. The reduction of spacing between rows and between plants in the planting row increases the productivity of coffee plants. The spacing between the rows and plants influences the growth and architecture of the coffee plant.

“…But for irrigated coffee under production, nutritional recommendations are still based on the behaviour of the rainfed crop. This may compromise development of the plants and lead to a lack or excess of nutrients, due to irrigated coffee having a different pattern of growth and productivity to the non-irrigated crop, as suggested by the results of various studies (CARVALHO et al, 2006;. REZENDE et al, 2010;SILVA;TEODORO;MELO, 2008;SOBREIRA et al, 2011).…”

-With the aim of establishing critical ranges for the leaf nitrogen (N) and potassium (K) levels in fertigated coffee crops under production, an experiment was carried out in the experimental area of the Sector for Coffee Cultivation of the Department of Agriculture at the Federal University of Lavras, in Brazil. Treatments consisted of five levels of fertilizer applied through fertigation: 30%, 80%, 130%, 180% and 230% of the recommended amounts of N and K for rainfed coffee grown in Minas Gerais. A randomised block design with four replications was used. Critical ranges for nutrient concentrations in the leaves were established from the results of growth characteristics (plant height and stem diameter), leaf analyses and productivity. The results obtained were: a) nitrogen (g kg -1): 32
