RAMIREZ-BUILES, Víctor Hugo  e  DUQUE, Nora Naidu. Response of the lulo fruit cv. La Selva (Solanum quitoense x Solanum hirtum) at the aerobic organic and inorganic fertilizer applications. Acta Agron. [online]. 2010, vol.59, n.2, pp.155-161. ISSN 0120-2812.

In this study four fertilization treatments in lulo crop (Solanum quitoense x S.hirtum) were evaluated, three organic with several manure sources like coffee skin , earthworm residues and chicken manure, and a four treatment consisted of inorganic fertilizer with a composition of 10-30-30 ( N,P,K) and a control without fertilizer applications. A complete block random design with three replications was used and each replication with 58 plants. The organic fertilization increase the soil pH, cation exchange capacity and soil organic matter. The best treatment was the aerobic fermented, based on chicken manure with a fruit yield average of 4731 kg .ha^-1, the rest of the organic treatments did no showed statistical differences with the inorganic fertilization and all were statistical different with the control without fertilizer applications, which showed a good crop response to the organic applications.
