    Increasing demand for maize in Nigeria has resulted in high use of inorganic fertilizers and these fertilizers are expensive for peasant farmers who dominate farming in the country. The use of inorganic fertilizers also results in hidden cost borne by man and the ecosystem. In a search for a cost-effective and safer alternative, six maize varieties were evaluated using moringa, banana-peel, maize-stalk fertilizer (MBM) both in solid and foliar forms. Gross benefit, net benefit and benefit-cost ratio (BCR) were used to determine enterprises with the highest economic returns. The results showed that maize varieties treated with 90 kg/ha of NPK had the highest grain yield which was significantly comparable with MBM. The application of 120N+50P+40K rate of MBM to single cross hybrid, SCH LY1312-1, resulted in the highest benefit-cost ratio (15.16). MBM is economically more viable than NPK Fertilizer and its application in the solid (powdered) form before planting produced double economic returns compared to foliar application. Single cross hybrids gave better economic returns when the fertilizer was applied in solid form.

    Response of maize (Zea mays L.) varieties to moringa-banana peel-maize stalk fertilizer and grain yield modelling.
    (Universidad Autonoma de Yucatan, 2021-12-15) Lawal, O.O. Yusuf, T.M., Aliyu, O.M., Olowoake, A.A., Subair, S.K. and Nofiu, N.B.
    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.
