2. Spatial variability of coffee plant water consumption based on the SEBAL algorithm
ABSTRACT: Awareness of evapotranspiration (ET) and crop coefficient (Kc) is necessary for irrigation management in coffee crops. ET and Kc spatial variabilities are disregarded in traditional methods. Methods based on radiometric measurements have potential to obtain these spatialized variables. The Kc curve and spatial variability of actual evapotranspirati

3. Regression models for growth description of the irrigated and unirrigated pruned coffee tree / Modelos de regressão para descrição do crescimento do cafeeiro irrigado e não irrigado após recepa
The irrigated coffee crop grown has expanded throughout the national territory, especially where production is more significant as Minas Gerais, Espirito Santo and São Paulo. Thus, irrigation has been a great producer ally, because, if well conducted, has reduced losses and increased profitability. The aim of this study was to test the linear and nonlinear

4. Parâmetros fitométricos e produtivos do cafeeiro irrigado e submetido a doses de nitrogênio na Região de Garanhus / Productive parameters of the coffee plant submitted to doses of nitrogen in the area of Garanhus
The coffee practiced in Pernambuco, today, occupies an area of 8 hectares distributed between the Mata Norte (500 ha) and 40 towns of the Wasteland (7.5 thousand hectares). Among the major producing towns stand out Taquaritinga do Norte, Garanhuns, Bom Conselho, Belo Jardim, Brejão and Triunfo. These areas are produced a volume of coffee that correspond onl

5. PROGRESSO DA FERRUGEM E DA CERCOSPORIOSE NA CULTURA DO CAFEEIRO IRRIGADO EM VÃRIAS DENSIDADES DE PLANTIO / Progress of rust and cercosporosis in irrigated cultivation of coffee in various densities of planting
The current coffee has been adopted new technologies to conduct and to manage crop, such as irrigation, fertigation and high plant densities in order to increase productivity and consequently, the profit. The aim of this study was to evaluate the effect of different irrigation methods applied in four plant densities by a drip system, its relation with the in

6. Fertirrigation of coffee crop with domestic sewage Risks of salinization and soil contamination / Fertirrigação do cafeeiro com esgoto doméstico Riscos de salinização e contaminação do solo
Due to the great availability, the use of domestic sewage in irrigated agriculture is an effective control of pollution, increase of water availability, showing economic, social, environmental and public health benefits. Nevertheless, the use of sewage must be well planned and managed to avoid problems of microbial contamination as well as negative changes o

8. Evaluation of the irrigation for central pivot in the coffee (Coffea canefhora L.) crop and papaya (Carica papaya L.) crop in the municipal district of Pinheiros-ES / Avaliação da irrigação por pivô central na cultura do café (Coffea canefhora L.) e na cultura do mamoeiro (Carica papaya L.) no município de Pinheiros - ES
The objective of the present work was to evaluate the irrigation management adopted for papaya (Carica papaya L.) and coffee (Coffea canefhora L.) production in the municipal district of Pinheiros at the north of Espírito Santo. Central pivot irrigation systems are used in the area. Eight pivots cultivated with papaya and six pivots cultivated with coffee w

9. Evapotranspiração de cafezal semi-adensado irrigado por gotejamento e sua relação com a evapotranspiração de referência / Evapotranspiration in a drip-irrigated hedgerow-coffee plantation and its relationship with the reference evapotranspiration
O uso crescente de irrigação na cafeicultura devido ao cultivo em áreas com maior deficiência hídrica exige conhecimento sobre o consumo de água da cultura. Para contribuir para esse conhecimento, a evapotranspiração global do cafezal (ETc) e sua partição nos fluxos componentes evapotranspiração das linhas de cafeeiros (ETlin), evapotranspiraçã

10. Flow variation of emitters under subsurface drip irrigation in citrus and coffee crops. / Variação de vazão de gotejadores enterrados na irrigação de citros e café.
This work aimed to quantify drippers performance under subsurface drip irrigation (SDI), regarding the flow variation due to root intrusion under citrus and coffee crops. The experiment was carried out inside a greenhouse during the year of 2001, at the University of Sao Paulo (ESALQ), in Piracicaba SP. Coffee seedlings and orange scions planted in vases wit
