  • Carvalho, Felipe Paolinelli de; França, André Cabral; Lemos, Vinícius Teixeira; Ferreira, Evander Alves; Santos, José Barbosa dos; Silva, Antonio Alberto da (Editora da Universidade Estadual de Maringá - EDUEM, 2013-01)
    Farmers use non-selective herbicides, such as glyphosate, in directed applications to control weeds in coffee crops. Despite the precautions used during the application of herbicides, there are usually reports of poisoning ...
  • Alves, Guilherme Euripedes; Borém, Flávio Meira; Isquierdo, Eder Pedroza; Siqueira, Valdiney Cambuy; Cirillo, Marcelo Ângelo; Pinto, Afonso Celso Ferreira (Editora da Universidade Estadual de Maringá - EDUEM, 2017-04)
    The objective of this study was to evaluate the correlation between a group of physiological variables (electrical conductivity, potassium leaching, and germination percentage) and a group of drying kinetics variables ...
  • Moraes, Bráulio Fabiano Xavier de; Toledo, Fernando Henrique Ribeiro Barroso; Dias, Kaio Olímpio das Graças; Andrade, Vinícius Teixeira; Ferreira, Daniel Furtado; Gonçalves, Flávia Maria Avelar (Editora da Universidade Estadual de Maringá - EDUEM, 2019)
    In most cases, in genetic breeding of Arabica coffee, plot size is defined in an empirical manner. It is often based only on the experience of the breeders and the availability of resources, potentially leading to a reduction ...
  • Zaidan, Úrsula Ramos; Campos, Renata Cássia; Faria, Rodrigo Magalhães; Zaidan, Iasmine Ramos; Souza, Wendel Magno de; Santos, Ricardo Henrique Silva; Freitas, Francisco Cláudio Lopes de (Editora da Universidade Estadual de Maringá - EDUEM, 2022-08-15)
    Intensive weed management is one of the most common practices in coffee cultivation areas. Consequently, some problems, such as soil degradation and the selection of herbicide resistant weed, have increased over time, but, ...
