Tolerance to drought of coffee trees produced by cuttings and somatic embryogen...
Dominghetti, Anderson William; Souza, Antônio Jackson de Jesus; Silveira, Helbert Rezende de Oliveira; Sant’Ana, José Antônio do ValeThe irrigation in coffee plantations is the focus of research for many years, but the new seedling production technologies (somatic embryogenesis and cuttings) have demanded new behavioral studies of these in the field and their water needs. An experiment was carried out in a greenhouse at the Federal University of Lavras, Lavras - MG, Brazil, aiming at to evaluate the tolerance to drought of coffee coming from...
Planting season and hydro retainer polymer on initial growth coffee
de Oliveira, Luiz Paulo Vilela; Dominghetti, Anderson William; Guimarães, Rubens José; Rezende, Tiago Teruel; Ferreira, Marcelo MachadoThis work aimed to verify the effect of coffee without irrigation of the planting season using the hydro retainer polymer in the initial plant growth. The experimental design was a randomized block, factorial design, with three replicates. The treatments consisted of six planting dates: October, November, December 2012, January, February and March 2013, as well as presence and absence of hydro retainer polymer ...
Levels of phosphorus in the initial development of coffee in soils with differe...
Jesus Souza, Antonio Jackson; Guimarães, Rubens José; Dominghetti, Anderson William; Scalco, Myriane Stella; Colombo, AlbertoAimed to evaluate phosphorus levels in soils with different textures in coffee. We used factor: 4 (phosphorus levels) x 3 (type of soil) in a randomized block with three replications. Evaluated: height, leaf area, leaf, stem diameter, dry mass of shoot, root, and total absolute growth rate, relative growth rate, leaf area index, leaf area ratio and rate of assimilation net. It was found maximum growth of plants...
