Abstract
Background. Low soil nutrient limit maize production in Nigeria, and inorganic fertilizer used in augmenting yield
are expensive and hazardous. Objective. In search for a sustainable alternative, the effect of methods of application
(foliar and incorporated) of different levels of moringa-banana peel-maize stalk fertilizer (MBPF) on the growth and
yield of different maize varieties was investigated. Methodology. Pot and field experiments were conducted. Each
experiment consisted of 2 x 4 x 6 factorial combinations. In the pot experiment, the treatments were laid out in CRD
while RCBD was used in the field experiment. All treatments were replicated three times. Data collected on
agronomic, aesthetic and yield traits were subjected to ANOVA using SAS 9.4 version. PCA was done, thereafter,
structural equation model (SEM) was constructed, and GGE biplot used to cluster treatment interaction using GEAR
4.1 version. Result. The results of both pot and field experiments had similar trend except that pot experiment had
reduced height, poor phenotypic appeal and reduced grain yield. The result showed that mode of application,
fertilizer treatments and maize varieties had significant (p<0.05) mean square for grain yield. 120N+50P+40K and
100N+40P+30K rate of MBPF applied to single cross hybrids (SCH) with grain yield of 1.85 t/ha clustered with
standard national recommended rate of NPK fertilizer. Grain yield was in the order of SCH LY1312-11 > SCH
check > Double-cross hybrid > Three-way hybrid > Top-cross hybrid > OPV-STR. Implication. MBPF was most
effective when incorporated into the soil a week before planting. Conclusion. Therefore, MBPF at 120N+50P+40K
and 100N+40P+30K are sustainable and eco-friendly alternative to inorganic fertilizer.
