Sažetak
The frequency and intensity of extreme weather events are likely to increase with climate change. Wheat (Triticum aestivum L.) production is critical to global food security. Climate change threatens sustainable wheat production not only through direct negative impacts on crop growth, but also through profound effects on the dynamics and severity of pests and diseases. Reducing yield losses is necessary to sustainably increase the efficiency of agricultural production and meet our current and future needs for food, fiber, animal feed, and biofuel. Our growing understanding of how crops respond to abiotic and biotic stress has led to the development of innovative sensing technologies to detect stress in crops and develop a rapid and simplified decision support system (DSS) for decision making in different phenophases and for effective interventions. Spectral vegetation indices (VI) are well-known and widely used tools for assessing wheat crop condition and predicting grain yields. This article describes methods for determining vegetation indices using remote sensing methods and their broad application. Vegetation indices can be used to estimate drought severity, detect pests early, assess crop nitrogen status, and predict biomass, leaf area index, and final yield.
