Irrigation Scheduling and Cultivar Management for Increasing Water Productivity under Dryland Condition: A Review

Abstract

In Dryland environments with limited water resources, irrigation scheduling and cultivar management are play pivotal roles in enhancing water productivity. Effective irrigation scheduling involves the judicious timing and amount of water application, considering factors such as soil moisture levels and crop growth stages. Utilizing advanced technologies, such as soil moisture sensors and remote sensing, facilitates precise irrigation management. This approach not only conserves water but also prevents waterlogging and salinity issues, promoting optimal plant growth. Cultivar selection is another critical aspect, focusing on identifying and cultivating crops that are well-adapted to arid conditions. Drought-resistant cultivars with traits like deep root systems and efficient water use contribute significantly to water productivity. Integrating modern breeding techniques and genetic engineering enhances the development of cultivars with improved drought tolerance, ensuring resilience in dryland agriculture. Furthermore, the implementation of agro ecological practices, such as conservation tillage and organic farming, complements irrigation scheduling and cultivar management. These practices enhance soil structure, water retention, and overall ecosystem health, fostering a more sustainable and resilient agricultural system. Adopting a comprehensive approach that combines precise irrigation scheduling, resilient cultivar selection and agro ecological practices holds great potential for increasing water productivity in dryland conditions. This integrated strategy not only addresses the challenges posed by water scarcity but also contributes to the long-term viability of agriculture in arid regions.
