TL;DR
This study explores how different weather conditions and fertilizer types affect maize growth and yield in Benin, finding that organic fertilizers and specific weather scenarios can boost productivity.
Contribution
The study introduces a novel split-plot experimental design combining specific weather scenarios and fertilizer types to evaluate their joint effects on maize growth and yield.
Findings
Intermediate 1 and organic fertilizers promoted greater maize growth in terms of height and diameter.
Organic and chemical fertilizers yielded higher results under weather scenario 2, while intermediate 3 and organic performed better under weather 1.
Weather scenario 2, with a broader range of climate parameters, was associated with higher maize yields.
Abstract
Maize is a major crop for food security, but its cultivation is threatened by climate change. Climate may affect the response of maize to fertilizer. This study examined the impact of weather parameters in combination with fertilizer types on maize growth and yield parameters in Benin. The experiment involved two sets of climatic scenarios. Scenario 1 (weather 1) had a moderate range of minimum and maximum temperatures and maximum humidity suitable for maize cultivation in Benin. Scenario 2 (Weather 2) featured a broader range of parameter values below and above those of Weather 1. Five types of fertilizers were tested: Organic (Cow dung), Chemical (NPK), Intermediate 1 (mixture of high NPK and low Cow dung), Intermediate 2 (mixture of middle NPK and middle cow dung), and Intermediate 3 (mixture of high cow dung and low NPK). These factors were combined in a split-plot design and data…
