Accurate assessment of crop vegetative state is crucial for agricultural management, particularly under varying environmental conditions. However, detailed field experiments face logistical and cost challenges. NDVI and other vegetation indices offer non-invasive and large-scale solutions for assessing plant health. The integral of the NDVI curve over time aggregates NDVI values, providing a comprehensive view of vegetation dynamics, surpassing insights from individual NDVI measurements and offering a comprehensive measure of plant. Developing robust methodologies to calculate the vegetation activity index (VAI) based on NDVI integral is essential for efficient vegetation evaluation, aiding sustainable agriculture. To test this, biostimulants were used to enhance plant growth and improve resilience to stressors, as sugarcane is vulnerable to environmental stresses, particularly drought.
