Abstract: Maize (Zea mays L.) is a multipurpose crop useful in human diet and animal feed. Maize yield improvement has continued to receive a lot of research attention, but less so for plant morphological characteristics especially considering the ongoing climate change impacts that have affected the response of many crops to the environment. The information that can be received from research on morphological traits could be critical, as it could enhance the efforts at ensuring proper crop adaptation to climate change, in addition to the direct or indirect contribution to grain yield. Five maize varieties were planted in randomized complete block design experiments and monitored in 8 environments at the Obafemi Awolowo University Teaching and Research Farm to examine the response of maize morphology to environments, seasons and weather factors. Result showed highly significant effect of environment on most measured traits (P ≤ 0.01) with significantly higher means in the early season. Beyond the seedling stage, morphological traits responded positively to soil moisture, relative humidity, and solar radiation, On the contrary, soil heat flux, temperature, and heat unit negatively affected maize seedling growth. Keywords: Climate change, crop phenology, crop physiology, growth analysis, seedling emergence and vigour.
