This chapter thoroughly investigates the vital role of sorghum (Sorghum bicolor) in arid agroecosystems, specifically emphasizing its significance in South Asia and sub-Saharan Africa. It highlights significant challenges in post-rainy sorghum production, attributing them to the complexities of genotype–environment interactions and the limited integration of essential physiological traits into sorghum breeding, further complicated by the absence of sophisticated, breeder-friendly phenotyping tools. To address these challenges, the chapter meticulously characterizes the post-rainy sorghum production areas in India, utilizing advanced modeling tools, revealing distinct production zones and drought stress patterns that impact yields, necessitating optimization strategies. Innovative approaches, like homogeneous system units, are introduced to augment sorghum production through well-planned genotype × management combinations. The chapter explores the modification of plant water-use traits as a potential solution to balance trade-offs between grain and stover production. It examines component traits crucial for drought adaptation, extending beyond grain yield considerations to factors such as limited transpiration, soil drought, and canopy development. Specific traits, including leaf size, leaf angle, transpiration efficiency, and the stay-green trait, are underscored for their pivotal roles in enhancing crop resilience to water constraints. The chapter also investigates potential molecular and genetic approaches to fortify sorghum drought adaptation. It concludes by emphasizing the complexity of enhancing drought adaptation in sorghum and advocates for precise phenotyping techniques, illustrated through sensor-based high-throughput phenotyping.
