1. Selection of conilon coffee clones tolerant to pests and diseases in Minas Gerais
Abstract In the northern Minas region, the dry-warm climate predisposes coffee plants to the occurrence of leaf miners, mites, cercosporiosis, and leaf scald. Aiming for the development of a cultivar adapted to these conditions, Coffea canephora Pierre ex A. Froehner clones were selected through genetic parameters under an irrigated system, without agrochemi

2. Dispersal capacity of fruit fly parasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae) in irrigated coffee plantations
ABSTRACT Diachasmimorpha longicaudata is an Old World parasitoid of tephritid fruit flies that was widely introduced in the Americas to control pest species such as the Mediterranean fruit fly Ceratitis capitata. Augmentative releases in irrigated coffee plantations in semiarid regions of Brazil are under consideration and dispersal capacity of D. longicauda

3. Efeito do déficit hídrico na uniformidade da floração do cafeeiro irrigado no oeste da Bahia / Water stress effect on the uniformity of irrigated coffee blossoming at West of Bahia
A utilização do déficit hídrico em cafeeiros irrigados para a quebra de dormência do botão floral e sincronização da floração, é de grande importância e vêm sendo estudado há vários anos devido seu enorme potencial de auxiliar na ocorrência de uma florada uniforme. Tal prática possibilita maior rentabilidade do sistema de produção em funç

4. Coffee leaf analysis using DRIS from irrigated and non-irrigated plantations in the alto Paranaíba region / Diagnose foliar em cafeeiro de sequeiro e irrigado na região do alto Paranaíba com o uso do DRIS
Cerrado soils have low fertility and under-dosing of fertilizers leads to nutritional imbalance on coffee plantations. This study aimed to: comparatively characterize the main deficiencies, nutritional imbalances and excesses in the aerial part of coffee plant; indicate nutrients which respond well to fertilization and their synergistic and antagonistic inte

7. 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

8. 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

12. Modelo para a análise de risco econômico aplicado ao planejamento de projetos de irrigação para cultura do cafeeiro. / Economic risk analysis model for coffee irrigation project design.
This study shows the application of an economic risk model to help the decision makers on planning process for coffee irrigation projects. The model was built in Excel sheet using Visual Basic Macro and the simulation process used Monte Carlo method. It was used data from two irrigated coffee farms located at Lavras, MG (13.5ha) and Araguari, MG (98.4ha). Th
