Comparative effect of organic, organomineral and mineral fertilizers on soil properties, nutrient uptake, growth and yield of maize (Zea Mays)

Many Researchers have shown that neither mineral fertilizers nor organic manures are a panacea for soil fertility management in Nigeria. This has led to the innovation of organomineral fertilizer which combines the attribute of both mineral and organic fertilizers. Field experiments were conducted in 2011 and 2012 to compare the effect of industrial manufactured organic (OG) fertilizer and organomineral fertilizer (OMF) at the rate of 0, 2.5 and 10t/ha; and NPK 15:15:15 fertilizer (NPK) at the rate of 300kg/ha on soil chemical properties, nutrient uptake, growth and yield of maize in Ondo, Southwestern Nigeria. The treatments were laid out in randomized complete Block Design with four replications and with…
