dc.description.abstractAbstract Maize is a cornerstone for global food security, yet its production is increasingly being challenged by climate change, limited resources, dietary shifts, and environmental degradation. This two-year study investigated the dynamics of dry matter and nutrient accumulation of two maize hybrids (Fornad and Mv 352) at different phenological stages in varying environmental conditions. Additionally, the impact of precision drip irrigation and foliar fertilization on maize vegetative attributes, yield and its components and grain quality traits were assessed in comparison to untreated control conditions. The results showed that, during the early vegetative stages, dry matter and essential nutrients were primarily accumulated in the leaves and stalks to support vegetative growth. During the reproductive stages, however, nutrient allocation shifted towards the kernels. Substantial amounts of N, P, K and Ca were absorbed by both hybrids during vegetative development. However, drip irrigation did not consistently enhance nutrient uptake at every growth stage. Overall, under irrigated conditions, only remobilized N, P, Zn and S (only for Mv 352) , contributed significantly to grain content (50% and above). Drip irrigation also had a positive effect on maize vegetative parameters. In contrast, foliar fertilization had a minimal effect on NDVI, but had a significantly positive influence on SPAD. Furthermore, irrigation increased plant height and yield by 4.3% and 19.9% respectively. Foliar fertilization significantly improved yields by around 6%. However, the application of foliar nutrition reduced grain moisture but increased protein content, despite this not being statistically significant. These findings underscore the significant differences in the response of the two hybrids to irrigation and foliar fertilization across different climatic conditions. Overall, Fornad consistently outperformed Mv 352 in terms of yield under both irrigated and rainfed conditions due to its greater drought tolerance and response to foliar fertilization.
