Production of arabica coffee seedlings on different organic substrates.

Abstract

In order to minimize expenditures on commercial substrates, it is necessary to conduct research aimed at the economic use of organic sources that present potential physical and chemical benefits in the production of coffee seedlings. The experiment was carried out in a 5x3 factorial scheme. Five substrate compositions (containing cattle and poultry manure, earthworm humus, organic compost and commercial substrate as a control) were tested and three epochs were considered in days after sowing. At 120, 150 and 180 days after sowing (DAS) were evaluated: Aerial part length (cm); Diameter of the stem, at the height of the cervix (mm); Root length (cm); Dry matter of shoot (g); Dry matter of the root (g) and Number of definitive leaves. The results of the statistical analyzes indicated that there was interaction between the substratum factors and days after sowing. Potential organic sources of poultry and bovine manure can be used as substrates to produce Arabica coffee seedlings and provided adequate nutrition.
