Importance of Corn's (Zea mays L.) crop is justified by its nutritious content especially because of the presence of high protein, minerals, vitamins and other energetic nutrients. In Côte d'Ivoire, maize production is insufficient and various strategies have been developed to improve its production. Present study was conducted in a ferralitic soil at the UJLoG's research station to evaluate the effect of two different ages (storage time) of chicken manure on growth and yield of GMRP-18 (an improved corn variety) and Bon-maïs (used for popcorn) varieties. Single dose of poultry manure at the rate of 7 t/ha was used in combination with 70 kg/ha. Various growth traits like germination rate, height, diameter, number of leaf, ear insertion level, number of ear per plant and yield have been evaluated. Results of study revealed positive impact of the manure on the growth and development of corn crops and highlighted the possibility of improving corn productivity in Daloa region by using poultry manure. Furthermore, higher plants growth was reported under the influence of fertilizer as compared to controls. Final yield is significantly enhanced by the contribution of manure and highest yield was reported on the six days wind stored poultry manure applied at the rate of 7t.ha -1 .
