Proper irrigation management contributes to increased crop yield by ensuring plants receive the optimal amount of water at critical growth stages, preventing stress from drought or waterlogging. This leads to healthier plants and better fruit/grain development. It contributes to water conservation by minimizing wastage through techniques like drip irrigation or sprinklers, which deliver water directly to the plant roots, reducing evaporation and runoff. Scheduling irrigation based on soil moisture and crop needs also prevents over-watering, making efficient use of a precious resource.
