The efficient rice establishment methods are essential to increasing yield and maximizing the use of water, given the increasing water shortages and the importance of sustainable agriculture. In focusing their implications on the agronomic performance and water use efficiency (WUE) in plain areas, the following review examines the agronomic basis, benefits, and drawbacks of the three primary innovations of rice establishment: Transplanted Rice (TPR), System of Rice Intensification (SRI), and Direct Seeded Rice (DSR). The advantages of DSR are faster growing crops and reduced labor and water costs. Some of its disadvantages include inadequate seedling establishment, uneven crop stands, and the presence of weeds in different field conditions. SRI enhances WUE and yield possible through methods such as younger seedlings, broader spacing, and alternate wetting and drying (AWD). Although it has its compensation, it also suffers shortcomings in terms of scalability because of the troubles of mechanization and popularization. TPR remainder the predictable technique because it reliably puts crops in the ground; however, with significant demands on both the water resource and labor resources, the topic of sustainability is problematic given current resource and climatic restrictions. To better improve the efficiency of such methods, there was also the assessment of how technical innovations such as sensor-based irrigation, incorporated nutrient management, and accurate field leveling might be helpful. It accounts significantly on the substance of matching techniques to their nutrient dynamics, plant physiology, irrigation plans and soil structure, to maximize on the results. EVR-SD The research also determines the need to establish models of the agriculture of rice that are local and provide efficiently viable and ecologically sustainable conditions, with consideration to regional agro-ecological factors.
