Abstract
The demand for maize continues to outstrip supply due to challenges such as low soil fertility, inappropriate agronomic practices, and infestations of pests and diseases. Hence, there is a need to explore sustainable solutions like Gliricidia sepium biochar and poultry manure as alternatives to improve maize yields while simultaneously enhancing soil chemical and physical properties. The study employed a 2 x 6 factorial experiment arranged in a Randomized Complete Block Design with twelve treatments and replicated three times. The treatments included; (i) two maize varieties (Obatanpa and Omankwa), and (ii) six fertiliser rates [10 t ha-1 Poultry manure (PM), 300 kg ha-1 NPK, 2.5 t ha-1 Gliricidia sepium biochar (GB), 150 kg ha-1 NPK + 1.25 t ha-1 GB, 1.25 t ha-1 GB + 5 t ha-1 PM and No fertiliser (Control)]. The results showed that Omankwa and Obatanpa planted on 10 t ha-1 PM tasseled (3 and 6 days) and silked (2 and 6 days) respectively earlier than the same varieties planted on the control during 2021. Obatanpa planted on 10 t ha-1 PM and 1.25 t ha-1 GB + 5 t ha-1 PM produced significantly higher plant height and wider stem diameter respectively at 12 weeks after planting across 2021 and 2022 than the control and Omankwa planted on same amendments. Obatanpa produced a significantly wider cob diameter than Omankwa in 2022. Obatanpa grown on 10 t ha-1 PM produced a significantly greater cob diameter than the control. Omankwa had a significantly higher total grain yield than Obatanpa in 2021. Omankwa and Obatanpa maize varieties planted on 1.25 t ha-1 GB + 5 t ha-1 PM were superior in grain yield which was 10.4% and 25.8% respectively higher than the same varieties planted on the control plot. For higher vegetative growth and total grain yield Obatanpa and Omankwa maize varieties planted on 10 t ha-1 PM and 1.25 t ha-1 GB + 5 t ha-1 PM are recommended to farmers.
