Yield of maize as treated with plant-based liquid fertilizers at varying concentrations and frequencies of application

Azolla (Azolla pinnata), water lettuce (Pistia stratiotes L.), and banana peel (Musa paradisiaca) are known to contain nutrients that can serve as an environmentally friendly fertilizer. Result indicated that liquid organic fertilizer (LOF) made from leachate mix of azolla, water lettuce, and banana peel has the potential to serve as an alternative source of nutrients for maize production, in lieu of inorganic fertilizers. Grain number per row, tip filling, weight of 100 grains, and grain yield can be maximized by three applications of LOF at 2, 4, and 6 WAP with a 10% concentration, or two applications at 2 and 4 WAP with a 20% concentration, or a single application at 2 WAP with a 30% concentration.
