The impacts of elevated temperatures and prolonged periods of water scarcity provide substantial obstacles to the cultivation of plants and the implementation of sustainable agricultural methods on a global scale. The objective of this study is to provide a comprehensive analysis of the various ways in which plants respond and adapt to drought and elevated temperature. This includes examining the effects on different plant components such as roots, shoots, and grain yield. Additionally, we will explore potential management strategies that might help alleviate the detrimental consequences of these stressors. The findings presented in this review are primarily derived from recent scientific research published in reputable scholarly journals. The publication’s sections focus on various plant responses, including root growth, transpiration, photosynthesis, water use efficiency (WUE), phenotypic flexibility, accumulation of low molecular mass compounds (such as proline and gibberellins), and the expression of specific genes and proteins to enhance tolerance to abiotic stresses. Plants use a variety of adaptive and avoidance mechanisms to endure unfavorable conditions. Understanding the physiological and biochemical responses of crops to harsh conditions is of paramount importance to devise strategies and methods for enhancing plant tolerance. This chapter also addresses management practices about soil and crop cultivation that can aid in alleviating the adverse effects of heat stress and drought. Conducting experiments that encompass the assessment of plant assimilate partitioning, phenotypic plasticity, and the discovery of stress-tolerant plant genotypes is crucial for advancing our understanding of response complexity and the future of plant breeding. Agronomic strategies such as modifying the timing of planting, employing seed priming techniques, utilizing foliar application of diverse macro- and micronutrients, and implementing the use of rhizobacteria have the potential to partially alleviate the negative impact of heat and drought stress. Breeding methodologies such as trait-based selection, inheritance research including marker-based selection, and genetic techniques utilizing transcriptome and metabolome analysis have the potential to facilitate the selection and development of crops with enhanced heat and drought stress adaptability and mitigation capabilities.
