Antecipação da produção e desenvolvimento da lavoura cafeeira implantada com diferentes tipos de mudas

Abstract

The objective of this work was to seek anticipation of production and to evaluate the development of coffee plantations implanted with different types of seedlings. The seedlings were produced between June 2003 and December 2005 when the experiment was installed in the field. The experimental design was randomized blocks with 15 treatments constitutedby different types of plants in three replications. The types of plants tested refers to different periods in nursery (six to thirtymonths), and volumes of various containers (27 bags x 32 cm, 16 x 25 cm, 11 x 22cm and tubes 120ml), trimmed and not trimmed (driven with one or two stems), seeds stored in cold, or with seedlings cultivated in a controlled environment, grafted,grafted or self-standing Franco, with rooted cuttings, formed with the full sun or “forcing” with nitrogen. We evaluated: the productivity (bags.ha-1) of the years 2007, 2008, 2009 and 2010, the accumulated productivity of these four years and the percentage of green fruits, cherries, raisins, dry and hollow in the year 2010. We conclude that: it is possible to increase productivity in the first harvests of coffee by utilizing pruned trees (with two steams) and a stay of 18 months in nursery bags 16x25cm, with ripening of the fruit similar to that of conventional seedlings without the the occurrence of hollow grains.
