“…Irrigation has a positive effect on coffee growth (Nazareno et al, 2003;Ferreira et al, 2013) with respect to the size and quality of the grains (Sakai, Barbosa, Silveira, & Pires, 2013), as well as the yield (Bonomo, Bonomo, Partelli, Souza, & Magiero, 2013;Sakai et al, 2015). Increased coffee plant yield resulting from higher water availability in the soil provided by irrigation is also associated with greater development of the vegetative parts of the plant canopy (Alves, Faria, Guimarães, Muniz, & Silva, 2000), especially the yield components of coffee plants, such as the number of branches per plant, number of nodes per branch, number of fruits per node and dry mass per fruit (DaMatta et al, 2007).…”

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.

“…A major climatic characteristic of the Cerrado biome is a well-defined dry season during winter and the recurrent occurrence of dry spell periods during the rainy season. Therefore, irrigation is an essential practice for achieving high yields, profitability, and high quality coffee grains (Bonomo et al, 2008;Lima et al, 2008;Costa et al, 2013;Sakai et al, 2013).…”

-The objective of this work was to evaluate the effect of irrigation and of the presence of brachiaria (Urochloa decumbens) between coffee (Coffea arabica) rows on coffee yield and on chemical and hydrophysical attributes of a Typic Haplustox. The study was conducted in the Cerrado region in Planaltina, Brasília, DF, Brazil, in a randomized complete block design, arranged in split-split plots, with four replicates. Water regimes (irrigated or rainfed) were assigned to the main plots, inter-row management systems to the subplots, and soil layers to the sub-subplots. The following soil attributes were determined: total organic carbon, total nitrogen, C/N ratio, carbon and nitrogen stocks, bulk density, aggregate stability, total porosity, macroporosity, low-retention microporosity, remaining microporosity, criptoporosity, and total and readily-available water, besides coffee yield. Irrigation of coffee plants, associated with brachiaria intercropped as a cover crop, increased coffee yield and favored chemical and hydrophysical soil attributes, improving soil structure and its ability to store water. Irrigation favors organic carbon stocks in the upper soil layers, whereas brachiaria favors soil physical attributes related to water availability to coffee.Index terms: Coffea arabica, Urochloa decumbens, cover crops, soil physical quality, soil porosity, water availability. Atributos químicos e físico-hídricos de um Latossolo sob cafeeiro consorciado com braquiária no CerradoResumo -O objetivo deste trabalho foi avaliar o efeito da irrigação e da presença de braquiária (Urochloa decumbens) nas entrelinhas do café (Coffea arabica) sobre a produtividade do cafeeiro e sobre os atributos químicos e físico-hídricos de um Latossolo Vermelho distrófico típico. O ensaio foi conduzido na região do Cerrado, em Planaltina, Brasília, DF, em delineamento de blocos ao acaso, com parcelas sub-subdivididas e quatro repetições. Foram alocados os regimes hídricos (irrigado ou não irrigado) nas parcelas, os sistemas de manejo das entrelinhas nas subparcelas e as camadas de solo nas sub-subparcelas. Os seguintes atributos do solo foram determinados: carbono orgânico total, nitrogênio total, relação C/N, estoques de carbono e nitrogênio, densidade do solo, estabilidade de agregados, porosidade total, macroporosidade, microporosidade de baixa retenção, microporosidade remanescente, criptoporosidade, e disponibilidade de água total e de água prontamente disponível, além da produtividade de café. A irrigação do cafeeiro, associada ao consórcio com braquiária como planta de cobertura, aumentou a produtividade de café e favoreceu os atributos químicos e físico-hídricos do solo, o que melhorou a estrutura do solo e a sua capacidade em armazenar água. A irrigação favorece o estoque de carbono nas camadas superficiais do solo, enquanto a braquiária favorece os atributos físicos do solo relacionados à disponibilidade de água para o cafeeiro.Termos para indexação: Coffea arabica, Urochloa decumbens, plantas de cobertura, qualidade física ...

“…Mundo Novo IAC 376-4 decotados e esqueletados submetidos a diferentes manejos de irrigação avaliadas em duas faces de exposição das plantas à radiação solar (FEPARS) e três posições na planta (PP) em Matão, SP Estudando a produtividade e rendimento do cafeeiro Rubi MG -1192 irrigado por pivô central, durante as cinco primeiras safras em Lavras (MG), Lima et al (2008) concluíram que o grau de maturação no momento da colheita influenciou o rendimento dos tratamentos, em especial aos grãos cerejas e secos. Em Mococa (SP), Sakai et al (2013) observaram em plantas não irrigadas de Catuaí Amarelo maior porcentual de grãos cereja e no tamanho dos grãos, quando comparada as plantas irrigadas. Assim se tornam importantes estudos relacionando às condições climáticas associadas à irrigação na extrapolação dos reais efeitos que a irrigação exerce sobre a classificação do café considerando o grau de maturação dos frutos antes do início da colheita.…”

Coffee is one of the most important non alcoholic beverages harvested in the field, exported under different ways and considered one of the most important commodities in the global market. The objective of this study was to investigate the effect of different irrigation management on some qualitative features of fruits and grains of coffee plants in two sides of exposure to solar radiation (SPESR) and three positions in the plant in the first harvest after pruning. The experiment was conducted using randomized blocks in a split-plot design with four replicates. It was developed in Matão (SP), Brazil, in the 2010/2011 harvest season. The primary treatments were six different types of irrigation management: NI = no irrigation; CI = continuous irrigation all over the year; CI 14 A-19 M = CI, except from . Secondary treatments were the SPESR: southeast and northwest. Ternary treatments were the position in the plant: upper third, mid third and lower third. The stages of fruit ripening and coffee rating by bean size, defects and tasting quality were evaluated. The irrigated and non irrigated coffee promoted the same increase in fruit ripening, however, the advance in maturation is observed from the upper to the lower third. Non irrigated and irrigated coffee plants promoted the same increase in total defects. Greater grains are obtained with sieve 16 in irrigated coffee plants and above the value in SPESR northwest over the mocha grain.In southeast SPESR, a higher increase in cherry fruit is observed, providing better quality of the beverage over total defects.
