In modern agriculture, efficient management of water resources is critical to maximizing crop productivity and minimizing environmental impacts. Water scarcity, increasing global demand for food, and the need for sustainable agricultural practices are driving the adoption of precision agriculture technologies.
One such innovation is Variable Rate Irrigation (VRI), which allows irrigation for each location based on plant and soil conditions in real time. VRI can optimize water use by adjusting irrigation patterns to crop needs, but requires accurate, timely data to be effective.
The Normalized Difference Vegetation Index (NDVI) is a widely used metric in precision agriculture that measures the health and vigor of vegetation. NDVI captures variations in plant greenness, which correlates with factors such as chlorophyll content, biomass and water stress. Integrating NDVI data into irrigation systems, particularly VRI, enables farmers to provide the right amount of water at the right time, addressing variability within a field.
In this thesis, modern methods of using NDVI data to guide variable rate irrigation will be presented. Specifically, it will present the relationship between NDVI and crop water stress, evaluate the accuracy of NDVI in determining irrigation needs, and highlight the yield improvements achieved through this method.
