TOMB AND OPERATIVE EFFECTS OF NITROGEN FERTILIZER AND CULTIVATION ON MAIZE PERFORMANCE IN A HUMID ENVIRONMENT

In 2017, a field trial was set up to see how different nitrogen fertilizer rates and land preparation methods tomb act to affect maize performance and yield in southwestern Nigeria. The trial was a 3 by 3 factorial; conducted in a split plot management with cultivation systems in a Randomized Complete Block Design. All treatments were replicated three times, with Convectional cultivation, reduced cultivation, and No-cultivation serving as the main plot and nutrient amendments rates serving as sub-plot factors. The parameters of growth and yield were the subject of an analysis of variance. Despite having the highest grain yield, no-till had the lowest plant height, stem diameter, and stover weight. At various N rates, grain yields did not statistically differ across all cultivation practices; however, the optimal N rate for maize production in the study area appears to be 60 kg N ha-1.
