Abstract

This study investigated the goodness of four (4) different types of organic fertilizers on crop (maize) yield. Data on kilograms of maize yield for the 2014/2015 planting season from four separate farms in which the four (4) different types of organic fertilizer (poultry droppings, piggery manure, extract from farm product and cassava sediment) were applied were collected from the Department of Soil Science, Akwa Ibom State University. SPLIT PLOT DESIGN and TWO-WAY ANOVA WITH INTERACTIONS models were used in carrying out the analysis. Hypothesis that was tested to ascertain whether there was a significant effect of the four types of organic fertilizer on maize yield indicated that, for both models, there was significant effect. When a pair-wise comparison via Least Significant Difference (LSD) was carried out to determine which of the four types of organic fertilizer was the best. For both models, results showed that extract from farm product was the best.
