Abstract
The aim of the study was to investigate the effect of varying light intensities on the growth and development of Zea mays (maize), a staple crop of global importance. The experiment evaluated key growth parameters, including plant height, leaf number, leaf area, chlorophyll content, fresh weight, dry weight, and root development under three distinct light intensity levels: high,
medium, and low. The results indicated that high light intensity promotes superior growth, as evidenced by greater biomass accumulation, increased leaf area, taller plants, and higher fresh and dry weights. Conversely, low light intensity results in reduced growth rates but induces an adaptive increase in chlorophyll content to maximize light absorption. Root development was
also significantly influenced, with high light intensity supporting robust root systems and low light leading to underdeveloped roots. This study highlights the critical role of light intensity in regulating photosynthesis and overall plant productivity. The findings provide valuable insights for optimizing agricultural practices to enhance maize yield, particularly in environments where
natural light is insufficient or inconsistent. Recommendations are made for strategic light management to ensure optimal maize growth in both traditional and controlled cultivation systems.
