Federal University of Lavras launches its latest quarterly edition of Coffee Science Magazine

The scientific magazine Coffee Science, published by the Federal University of Lavras – UFLA, under the Coffee Research Consortium, coordinated by Embrapa Coffee, presents in its volume 11, number 2, 2016articles that evaluate the use of flexible extenders in mechanized harvesting in coffee plantations in the first harvest; correlation of fruit detachment force in coffee trees under different nutritional conditions with a view to mechanized selective harvesting; progenies of coffee trees from the Catucaí group carrying characters of interest to coffee agribusiness; deposition of syrup caused by sprayers used in mountain coffee farming; coffee borer breeding techniques, using different sources of natural food, forms of asepsis and storage; and the levels of caveol and cafestol diterpenes in coffee drinks prepared from commercial espresso capsules on the Brazilian market; between others. The Magazine, published quarterly, includes original articles complete with translation into English and is available on Coffee Observatory, from Consórcio Pesquisa Café, and on the magazine’s website Coffee Science from UFLA.

Regarding the mechanization of coffee farming, one of the articles published was "Use of flexible extenders in stripping first harvest coffee plantations", which concluded that the use of rubber extenders increases the quantity of coffee harvested by 16,6%, that the harvesting of first-crop coffee must be carried out with harvesters adapted for this situation and that Cultivar Tupi IAC 1669-33 presents great difficulty in being harvested mechanically in the first harvest, and must be harvested with two mechanized operations.

The article "Correlation of fruit detachment force in coffee trees under different nutritional conditions" evaluated the detachment force of fruits in green and cherry maturation, aiming to verify whether these parameters are correlated with the nutritional condition and soil moisture and indicated, among other results, , that the increase in soil moisture, at certain depths, leads to a decrease in the detachment force of cherry fruits.

Among the articles in this edition is the work entitled "Selection of progenies of coffee trees from the Catucaí group" which evaluated, in the Experimental Field of Três Pontas, of the Agricultural Research Company of Minas Gerais – Epamig – another institution that is part of the Café Research Consortium - progenies of coffee trees from the Catucaí group carrying characters of interest to coffee agribusiness. In the research, coffee genotypes with favorable characteristics of productivity, grain size, vegetative vigor and resistance to rust were selected with the aim of obtaining cultivars with favorable agronomic characters through genetic improvement.

This edition also brings the work "Syrup deposition promoted by sprayers used in mountain coffee farming" which evaluated different equipment in pesticide applications in mountain coffee farming (motorized knapsack sprayer, tricycle adapted for spraying, adapted motorized knapsack sprayer and manual knapsack sprayer). , associated or not with electrostatic technology and silicone adjuvant, at different application rates. Study results revealed that electrostatic technology, associated with the use of silicone adjuvant, is better than the others, as it promotes improvement in syrup deposition in adult mountain coffee trees, especially in relation to adapted equipment, among other conclusions.

The article entitled "Diterpene contents in espresso coffee drinks prepared with commercial capsules" quantifies the diterpenes caveol and cafestol in coffee drinks prepared from commercial espresso capsules on the Brazilian market. Beverages from four types of capsules were evaluated with five preparation repetitions. Considering the quantified cafestol levels and the average daily consumption of espresso coffees by Brazilians, there is an indication that consumption would not imply a hypercholesterolemic effect.

Other results relevant to coffee farming are demonstrated in the other articles in this edition of Coffee Science Magazine: "Effect of light and temperature on the pathosystem Cercospora coffeicola and Cafeeiro", "Adaptation of technique for rearing of the coffee berry borer [hypothenemus hampei (Ferrari)]", "Soil physical quality under intercropped and monoculture conilon coffee", "Geostatistics and exploratory factor analysis for spatial representation of soil chemical attributes in coffee farming", "Life table ofPlanococcus citri (Laughter) and Planococcus minor (Maskell) (Hemiptera: Pseudococcidae) in coffee trees", "Agrometeorological modeling for predicting coffee tree productivity in the southern region of the state of Minas Gerais", "Granulometry and roasting in water sorption in conilon coffee during storage", "Brands versus cultivar denominations present, in two Brazilian geographical indications for coffee" and "Toxic levels of iron in conilon coffee crops (Coffea canephora L.) in coastal plateau soils".
