Impact of organic fertilization on maize (Zea mays L.) production in a ferralitic soil of centre - West cote d’ivoire

Abstract

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 .

“…The results of the analysis of the variance showed that the treatment given had no effect (P> 0.05) on the production of fresh forage grass of Setaria splendida Stapf. In the treatment of harvest age between 35 days to 45 days and liquid organic fertilizer from traditional market waste from concentrated to runny, does not provide the maximum conditions of each treatment [24]. However, the combination treatment of mixing liquid organic fertilizer with water at a ratio of 1: 1 with a harvest age of 45 days, has provided the highest level of fresh forage production of Setaria splendida Stapf grass which is as much as 2.2 kg per plot or 1.1 kg per square meter = 99,000 kg per hectare per year.…”

“…Added that leaves are important biomass in the production of forage, leaves are the highest quality vegetative part. [29] according to the opinion of [30] that each plant has its own productive age.…”

Desenvolvimento E Produtividade Do Milho BRS Gorutuba Sob Diferentes Lâminas De Irrigação E Adubação Orgânica

“…A ausência de esterco para o cultivo do milho, mesmo com o aumento das lâminas de água aplicada, é afetada, isso evidencia a importância da reposição de nutrientes advindo do esterco para a cultura, principalmente em solos com baixa fertilidade, como o utilizado nesse experimento (Tabela 1). Segundo Soro et al (2015), os resultados da adubação orgânica na produção de grãos de milho têm demonstrado produtividade semelhante aos da adubação química equivalente, pois ao estudarem o uso de esterco de aves no cultivo do milho, verificaram impacto positivo no crescimento e desenvolvimento da cultura. No caso do esterco caprino, os resultados são promissores também, conforme observado por Melo et al (2009) e Souza et al (2017).…”
