1. Response of Maize Hybrids to Variable Planting Densities and Nitrogen Fertilization: Evaluate the effects of different planting densities and nitrogen application rates on yield, agronomic traits, and profitability of promising maize hybrids.

2. Physiological and Agronomic Response of Maize Hybrids to Intercropping Systems: Assess the yield stability, resource utilization, and competitive ability of contrasting maize hybrids when intercropped with legumes or other companion crops.

3. Evaluation of Maize Hybrids for Drought Tolerance in Marginal Environments: Identify and screen promising maize hybrids with improved drought tolerance mechanisms under field conditions in low-rainfall regions.

4. Physiological Basis of Hybrid Vigor in Maize: A Comparative Study: Conduct physiological and biochemical analyses to understand the underlying mechanisms responsible for heterosis in selected maize hybrids.

5. Genetic Dissection of Key Physiological Traits Related to Yield in Maize Hybrids: Use genetic mapping and quantitative trait locus (QTL) analysis to identify genomic regions associated with important physiological traits, such as leaf photosynthetic rate or water use efficiency.

6. Evaluation of Maize Hybrids for Resistance to Common Pests and Diseases: Screen promising maize hybrids for resistance to major pests (e.g., stem borer, fall armyworm) and diseases (e.g., leaf blight, maize streak virus) under field infestation conditions.

7. Physiological Responses of Maize Hybrids to High-Temperature Stress: Study the impact of elevated temperatures on physiological parameters (e.g., leaf gas exchange, water relations) and yield components of contrasting maize hybrids.

8. Evaluation of Maize Hybrids for Nutrient Use Efficiency: Quantify the nitrogen, phosphorus, or potassium use efficiency of selected maize hybrids in response to varying soil nutrient availability.

9. Physiological Basis of Yield Stability in Maize Hybrids Across Variable Environments: Investigate the physiological traits (e.g., canopy architecture, root morphology) that contribute to yield stability of promising maize hybrids under diverse agro-ecological conditions.

10. Participatory On-Farm Evaluation of Maize Hybrids for Adaptation to Smallholder Farmers' Practices: Engage smallholder farmers in on-farm trials to assess the agronomic performance, acceptability, and profitability of new maize hybrids under their specific production systems.
