Desenvolvimento inicial do café conillon (Coffea canephora Pierre) em solos de diferentes texturas com mudas produzidas en diferentes substratos

Abstract

The objective of this work was to evaluate the initial development of conillon coffee (Coffea canephora Pierre) in soils with different textures using seedlings produced in different substrates. The experiment was conducted in greenhouse, in the Municipal District of Alegre-Es, using seedlings of conillon coffee (Coffea canephora Pierre). The seedlings were produced in plastic tubes containing the following substrates: Plantmax® + soil (1:1 v/v); homemade substrate (soil + bovine manure + sand 1:1:1 v/v/v); and Plantmax® (soil + coffee husk 1:1 v/v). After 140 days, the seedlings were transplanted to 10-L containers with two types of soil: sandy-clay and clay textures, in a 4X2 fatorial arrangement (4 levels of substrate and 2 levels of soil), in a complete randomized design, with three repetitions. At 150 days post-planting, the following agronomic parameters were evaluated: seedling height, stem diameter, crown diameter, leaf area, fresh and dry mass of aerial part and fresh and dry mass of root system. The treatment comprising seedlings produced in commercial substrate + soil followed by transplanting to soil with sandy-clay texture provided the best initial development of conillon coffee.
