The objective was to develop and test a procedure for applying variable rates of fertilizers and evaluate yield response in coffee (Coffea arabica L.) with regard to the application of phosphorus and potassium. The work ...
Trait selection using procrustes analysis for the study of genetic diversity in Conilon coffee

Pontes, Daiana Salles; Rosado, Renato Domiciano Silva; Cruz, Cosme Damião; Nascimento, Moysés; Oliveira, Ana Maria Cruz; Pensky, Scott Michael (Editora da Universidade Estadual de Maringá - EDUEM, 2020)

Trait selection is occasionally necessary to save money and time, as well as accelerate breeding program processes. This study aimed to propose two criteria to select traits based on a Procrustes analysis that are poorly ...
Use of different spray volumes and hydraulic nozzles in air-assisted electrostatic insecticide application technologies to control coffee berry borer (Hypothenemus hampei) populations

Zampiroli, Renan; Parenti, Matheus Vilhena; Alvarenga, Cleyton Batista de; Celoto, Fernando Juari; Cunha, João Paulo Arantes Rodrigues da; Rinaldi, Paula Cristina Natalino (Editora da Universidade Estadual de Maringá - EDUEM, 2022-03-09)

Chemical control is essential for efficient pest management in coffee crops. Application technologies should safely deliver insecticides to the target whilst protecting the environment, insecticide applicators, and consumers. ...

Greco, Marcelo; Campos, Alessandro Torres; Klosowski, Elcio Silvério (Editora da Universidade Estadual de Maringá - EDUEM, 2010-10)

Objetivou-se no presente trabalho avaliar a eficiência energética na secagem de café (Coffea arabica L.) em secador de camada fixa, empregando-se diferentes combinações de tempo de revolvimento. O experimento foi realizado ...
Vegetative growth of Conilon coffee plants under two water conditions in the Atlantic region of Bahia State, Brazil

Covre, André Monzoli; Partelli, Fábio Luiz; Bonomo, Robson; Braun, Heder; Ronchi, Cláudio Pagotto (Editora da Universidade Estadual de Maringá - EDUEM, 2016-10)

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 ...
Water use efficiency by coffee arabica after glyphosate application

Carvalho, Felipe Paolinelli de; França, André Cabral; Souza, Bruna Pereira de; Fialho, Cíntia Maria Teixeira; Santos, José Barbosa dos; Silva, Antonio Alberto da (Editora da Universidade Estadual de Maringá - EDUEM, 2014-07)

Many coffee growers apply glyphosate in directed applications, but some phytotoxicity has been noted. It is believed some herbicides can exert a direct or indirect negative effect on photosynthesis by reducing the metabolic ...
