This paper aimed the antecipation of the production by using different types of seedlings in coffee cultivation implementation. The experiment was carried out in the Farming Department Coffee Section at the Federal University of Lavras. Seedlings used in the experiment were produced over the period from June, 2003 to December, 2005 and the experiment set into field in December, 2005. The experimental design used was the 15-treatment-random blocks formed by seedling types and three replicates. Each split-plot was formed by three plant lines, six plants each row, being the useful area formed by four plants from the central row. The cultivation was implemented using 3,8 x 0,7m line space and between plants, respectively. Evaluations were carried out from May, 2007 to July, 2008. Plant height, plant stem diameter (mm), number of plagiotropic branches, number of knots on plagiotropic branches, productivity over beneffiting coffee sacks per hectare and fruit ripening stage in the harvest were estimated. Phenotipic correlation between plant characteristics and productivity was carried out. It has been concluded that the using of "pruning 2 1/2 year-old seedlings", "non-pruning 1 1/2 year-old seedlings", and "seedlings with kept seeds from the previous year" gave on average six beneffiting coffee sacks further than conventional seedlings. The grafting did not contribute to the antecipated production. The using of pruning did not provide antecipated production seeing that non-pruning treatment over "1 1/2 year-old seedlings" produced more than in pruning at the same age, and showed the same production for "pruning 2 1/2 year-old seedlings". Based on the estimate plant characteristic analyses seedlings formed over years preceding the planting showed higher growth. The production character revealed high positive phenotipic correlation between plant height, number of knots on plagiotropic branches and number of plagiotropic branches characteristics. However, it did not show consistent correlation results for the stem diameter.
