INTERACTION OF K AND B IN THE INTENSITY OF COFFEE RUST IN NUTRIENT SOLUTION
Vasco, Gabriel Brandão; Pozza, Edson Ampélio; Silva, Marília Goulart da; Alexandre Pozza, Adélia Aziz; Chaves, EugênioThis study aimed at assessing the interaction of potassium (K) and boron (B) in the coffee rust intensity in a nutrient solution. The experiment which was performed in a greenhouse was set up in the randomized complete block design (DBC) with four replicates. The experimental unit involved a single vase with two Catuaí Vermelho (IAC 144) cultivars. The treatments included five doses of boron (0.05, 0.50, 1, 2 a...

Vasco, Gabriel Brandão; Pozza, Edson Ampélio; Scalco, Myriane Stella; Santos, Leone Stabile Dias; Custódio, Adriano Augusto de PaivaThe objective of this study was to evaluate the incidence of cercospora leaf spot, on coffee plant fruits, under different irrigation management and planting densities. The trial was carried out at the Federal University of Lavras in the agricultural year 2008/2009 and 2009/2010, and collected 320 fruits per plot. The experimental design was a randomized block with four replicates. The treatments correspond to ...
Incidence of the phoma leaf blight in drip irrigated coffee trees under differe...
Santos, Leone Stabile Dias; Pozza, Edson Apélio; Faria, Manoel Alves de; Silva, Mirian de Lourdes Oliveira e; Custódio, Adriano Augusto de PaivaThe knowledge that the disposition of the crop and the irrigation management affect the microclimatic conditions is of importance for the sampling and quantification of diseases, assisting in the achievement of a better management of the crop. This work aimed at evaluating the influence of drip irrigation management in the incidence of phoma leaf blight (Phoma tarda (R.W. Stewart) H. Verm.) on coffee trees, reg...
