Abstract:
Rice (Oryza sativa L.) is one of the most important cereal crops of the world, grown in wide range of climatic regions, to nourish the mankind. The abstract explores the multifaceted impact of diverse nutrient management practices, varying quantities, and innovative application techniques on the overall performance of Rice. The study delves into the intricate interplay between nutrient availability and rice growth, yield, and quality. Through an exhaustive review of pertinent literature and empirical analysis, the implication of nutrient management strategies in augmenting rice production can be understood. Key findings indicate that the choice of nutrient management practice significantly influences rice productivity. Organic and inorganic fertilizer applications, as well as integrated approaches, exhibit distinct effects on growth, nutrient uptake, and yield parameters. Furthermore, the ration of nutrients administered proves to be a critical factor, with both deficiency and excess leading to suboptimal outcomes. Achieving an equilibrium between nutrient supply and crop demand emerges as a pivotal consideration. Innovative application techniques, such as foliar spraying, fertigation, and precision nutrient delivery, offer novel avenues to enhance nutrient utilization efficiency. These techniques allow for targeted nutrient delivery, mitigating losses and maximizing plant uptake. Consequently, they contribute to elevated yield potential, improved grain quality, and sustainable agricultural practices. The need for context-specific nutrient management strategies, taking into account soil properties, climate conditions, and rice cultivars. In conclusion, the intricate relationships between nutrient management practices, quantities, and application techniques, elucidating their profound influence on the performance of Rice. The synthesis of empirical evidence and theoretical perspectives provides valuable insights for policymakers, researchers, and practitioners striving to advance sustainable rice cultivation and bolster global food systems.
