Quality of Coffea arabica seedlings produced in different nurseries in southern Minas Gerais, Brazil

Obtaining high-quality seedlings is a step of fundamental importance for the successful implementation of a coffee crop, which can be measured by evaluating seedling morphological and quality parameters. This study examines the quality of coffee seedlings produced in nurseries in the municipalities of Inconfidentes, Ouro Fino, and Jacutinga, southern Minas Gerais State, Brazil. The experiment was carried out in nurseries here termed 1, 2, 3, 4, 5, 6, 7 and 8, from 05/28/2017 to 02/28/2018. The experiment was developed in an 8 × 2 factorial arrangement consisting of 8 seedling nurseries and 2 cultivars (Catuaí strains IAC 62 and 144) evaluated in 3 replicates containing 8 seedlings each. The following traits were evaluated: leaf area (LA), total dry matter (TDM), shoot: root ratio (S: R), plant height: stem diameter ratio (HDR), and Dickson quality index (DQI). Data were subjected to combined analysis and, after significant differences were detected (p
