Este estudo teve como objetivo,avaliar ao longo do tempo, o índice de área foliar do cafeeiro arábica, cultivar Catiguá MG-3, sob diferentes níveis e formas de parcelamentos de adubação. O cafeeiro foi plantado em maio de 2007, no espaçamento de 2,5 x 0,6 metros.O delineamento foi em blocos casualizados, com três repetições, utilizando uma adaptação da análise conjunta de experimentos, com o esquema de parcelas...
O objetivo deste trabalho foi determinar o parcelamento e a dose de nitrogênio e potássio mais adequados para o primeiro e segundo anos de formação do cafeeiro (Coffea arabica) fertirrigado por gotejamento, no sul de Minas Gerais. Dois experimentos foram instalados simultaneamente com plantio adensado (6.666 plantas ha-1): em um, a adubação foi realizada em quatro aplicações ao ano e, no outro, em 12 aplicações...
The objective of authors was to describe and analyze, by means of the Brody and Logistics models, the evolution of the diameter of the canopy of coffee plants, cultivated in two planting densities and submitted to five irrigation regimes, after pruning. The analyzed data are originated from an experiment performed at the Universidade Federal de Lavras, in Lavras, Minas Gerais. After pruning the crop, the data w...
The coffee yield is strongly influenced by adequate supply of water and nutrients to plants. Because not all soil is the ideal amount of nutrients for plant growth, fertilization is intended to supplement these nutrients. The nole of fertigation is to provide coffee the water volume to be supplied with nutrients and preventing entering the plant water stress and nutrition. This study was carried out in the expe...
The 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 ...
Aimed to establish bands and, or critical levels of foliar concentrations and optimal level of fertilization with nitrogen, phosphorus and potassium to fertirrigated coffee in formation. The experiment was carried out in the field in Setor de Cafeicultura da Universidade Federal de Lavras - MG, March 2010 to July 2013. The experimental design was a randomized block design with six treatments and four replicates...

The study had as objective to establish critical ranges of foliar and find the best level of fertilization with nitrogen, phosphorus and potassium for coffee fertirrigated in the first year after planting. The experiment was carried out in field conditions in the Coffee Culture Sector of the Agriculture Department, Federal University of Lavras, MG, from March2010 to July 2012. The experimental design was random...
Aimed 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...
Agricultural products constitute one of the bases of the Brazilian economy, and between them stands out the coffee. The objective of this study was to evaluate, over time, the vegetative growth of coffee plants, Rubi MG 1192 grown in densities 3333 and 10000 plants ha-1 and irrigation regimes control, 20 kPa and 60 kPa. The data are from an experiment carried out in Lavras, Brazil, using randomized blocks desig...
