Sažetak
Sustainable and profitable crop production is often challenged by abiotic and biotic stress. But with advancement of technology in precision agriculture, application of innovative sensors for data acquiring provided rapid and simplified decision-making tool for timely intervention during vegetation period. Aim of this study is to track phenological dynamics of important continental field crops (wheat, barley, corn, soybean, oats) in area of Experiment Station Šašinovec (University of Zagreb Faculty of Agriculture) using high-tech tool such as UAVs. For acquiring needed information, we used DJI Phantom 4 multispectral drone. This type of high- precision drone, equipped with a multispectral camera array with 5 cameras is widely used for gathering precise, plant-level data. During the growing season there were three different times of data collection. Gathered data was processed with computer software Pix4D Fields, an advanced agriculture mapping software. Using the software, we generated different vegetation indices, such as: NDVI, VARI, TGI, SIPI2, LCI and MCARI. The indices analyse how plants reflect light on a near-infrared spectrum. From several possibilities of indices, we chose Normalized difference vegetation index (NDVI) values as it could give distinguishable results between crops and phenological phases. The goal of the research was to explore the added value of the UAV in the test-area which resulted with the possibility for improving crop production. Furthermore, this research will set the foundation for future collaboration between agricultural experts and scientists.
