Real-Time Nitrogen Detection System of Corn Crop Using a Multi -Spectral Imaging Sensor
Abstract
dc:descriptionReal-time N-deficiency was estimated by using NDVI and mapped relative to unstressed healthy plants. The MSIS system provided a measure of crop response that correlated with plant SPAD measurements (-0.93 for G channel and -0.88 for R channel). The system had smaller measurement variation than the SPAD meter with a standard deviation of 0.13 in MSIS measurements whereas 0.26 in SPAD measurements. The MSIS-based supplemental N treatment improved the crop N status and increased the yield in one case, while in other case no yield improvement was observed with MSIS-based fertilization.
