This research paper explores the pivotal role of photosynthesis in global food production, with a primary focus on rice as a staple crop. It delves into the multifaceted challenges posed by low light stress during the wet monsoon season, a phenomenon that significantly impacts rice yield. The study's overarching objectives encompass assessing the influence of low light stress on photosynthesis and yield, identifying the key physiological parameters associated with stress tolerance, analyzing the dynamic influence of stress at different growth stages, exploring the intricate correlation between photosynthetic rates and leaf characteristics, investigating nitrogen utilization efficiency under stress conditions, and meticulously characterizing elite rice varieties for their low light stress tolerance. The findings derived from this comprehensive investigation provide invaluable insights and lay the foundation for innovative strategies aimed at ameliorating rice production in regions particularly vulnerable to low light stress.iRice (Oryza sativa) is a fundamental staple crop globally, sustaining a substantial portion of the world's population. However, the optimal growth of rice primarily relies on abundant sunlight. The challenge arises when rice cultivation must contend with low light conditions, a common occurrence due to factors such as overcast weather, dense canopies, or shading from surrounding vegetation. This comprehensive investigation delves into the physiological parameters and tolerance mechanisms crucial for enhancing rice production under such challenging circumstances. To address this issue, researchers have explored a myriad of strategies and technologies to improve rice yields in low light environments. These endeavors involve the selection of rice varieties with inherent low-light tolerance, optimizing planting techniques to maximize light exposure, and implementing innovative approaches like artificial lighting when necessary. iiPhysiological parameters such as chlorophyll content, photosynthetic efficiency, and nutrient uptake play pivotal roles in understanding and enhancing rice performance under low light. Additionally, studies on root architecture and water management offer insights into optimizing resource utilization in constrained light conditions. Tolerance mechanisms involve genetic modifications and breeding programs aimed at developing rice varieties with heightened resilience to low light stress. Furthermore, integrated pest management practices and strategies to combat diseases become crucial in preserving the health and productivity of rice crops when natural light is limited. In summary, this investigation explores the multifaceted aspects of rice cultivation in low light conditions, addressing both the physiological intricacies and tolerance mechanisms essential for augmenting rice production. By synthesizing current research and innovative practices, this study contributes to the advancement of sustainable rice farming practices, ensuring food security in regions where sunlight is a limiting factor.
