Resumo Inglês:
The aim was to evaluate the effect of chicken manure and substrate liming in the Campomanesia xanthocarpa (‘gabiroba’) physiology, nutrition and growth. Five dosages of chicken manure (0; 5; 10; 15 and 20 Mg ha-1) were studied without and with substrate liming. The treatments were arranged in a 5 x 2 factorial scheme, in a randomized block design with four replications. There was an improvement on the chemical attributes in the substrate and nutrients contained in the plants where liming was performed. The highest plant height of C. xanthocarpa occurred with liming and 9.03 Mg ha-1 of chicken manure. The diameters were liming-grown plants and 4.57 mm with 5 Mg ha-1 of chicken manure. The photochemical efficiencies of PSII occurred in plants grown on liming substrate. It was concluded that C. xanthocarpa plants had their development optimizes with substrate liming and incorporation of 5 Mg ha-1 chicken manure.
