Shaded cultivation of coffee (Coffea sp.) is a common practice from its center of origin, being currently used to add value to agroforestry systems, with slow maturation and selective harvesting of grains, shading can provide a better quality drink. The objective was to evaluate the effect of different sources of fertilizers, of organic and mineral nature, on the chemical attributes of the soil, in addition to monitoring the initial development of coffee cultureintercropped with banana (Musa sp.) and baruzeiro (Dipteryx alata ), into na agroforestry in the cerrado of Goiás. The work was carried out at the agronomy school of the Federal University of Goiás, located in Goiânia, Goiás, in a LATOSSOLO VERMELHO acriférrico típico. The experimental design was a randomized block, with 5 blocks and 5 treatments, with the control without maintenance fertilizer, an organic compound of its own formulation, cattle manure, chicken litter and commercial phosphate mineral fertilizer. The Arabica variety, cultivar MGS Paraiso 2, was used, and the soil was corrected and fertilized in a pit, with chemical analyzes of the soil before and at the end of the experiment. The following coffee development analyzes were performed: height, stem diameter, number of branches and evaluation with a chlorophyll meter. Plant height, fruit production and diameter at breast height (DBH) were measured in baru trees and the circumference of the pseudostem in banana plants. There was no significant difference between treatments for height, stem diameter and chlorophyll for coffee plants. The control treatment did not meet the demand for the number of branches criterion, which is directly linked to coffee productivity. The baruzeiro and banana trees were indifferent to the handling carried out on the coffee trees. The initial development of coffee was not hindered by a system intercropped and shaded, and also did not respond to organic fertilization during the study period.
