Abstract :Accelerated compost insert ignore into journalissuearticles values(AC); biotechnology that reduces composting time to less than one month is gradually finding its way to farmers. This study therefore evaluated the fertilizer potential of a brand of commercial AC insert ignore into journalissuearticles values(OBD-plus); on a degraded Alfisol in Ibadan insert ignore into journalissuearticles values(derived savannah); and Ultisol in Ikenne insert ignore into journalissuearticles values(rain forest); of Nigeria, using maize as a test crop. The experiment was laid out in Randomized Complete Block Design with three replications. The treatments were AC at 0, 60, 90, 120, 150 and 180 kg N ha-1, mineral fertilizer insert ignore into journalissuearticles values(NPK 15-15-15); and conventional compost insert ignore into journalissuearticles values(CC);, each at 60 kgN/ha. Data collected on biomass yield, maize grain yield insert ignore into journalissuearticles values(MGY, t ha-1); and post-cropping soil chemical properties were subjected to ANOVA at α0.05. The average highest MGY from Ibadan insert ignore into journalissuearticles values(3.90); and Ikenne insert ignore into journalissuearticles values(3.86); were obtained from AC insert ignore into journalissuearticles values(180 kg N/ha);, but these were not significantly different from other AC rates and NPK. The least MGY was obtained from control insert ignore into journalissuearticles values(2.1 and 2.0); which was significantly less than the CC insert ignore into journalissuearticles values(3.16 and 2.90);. The AC improved the post-cropping soil pH, N and K. The mean MGY obtained from the six levels of AC in Ibadan; 3.44 and 3.98 t ha-1 in 2013 and 2014 were not significantly different from Ikenne insert ignore into journalissuearticles values(3.41 and 3.84 t ha-1);. However, maize in Ibadan gave significantly higher biomass yield insert ignore into journalissuearticles values(19.40 t ha-1); than that of Ikenne insert ignore into journalissuearticles values(17.74 t ha-1); in 2013, with similar trend in 2014. Accelerated compost at 60 kg N ha-1 improved maize grain yield and post cropping soil properties in Ibadan and Ikenne, Nigeria as much as conventional compost. The performance of the accelerated compost was not location dependent in terms of MGY, but resulted in higher biomass production in the derived savannah ecology.
