TEA PLANT HEALTH RESEARCH USING SPECTROMETER

Tea leaves are the most important part for consumption. Leaves that healthy have a distinct color, while not color is very different from original. Chlorophyll in effects reflection of infrared light, allowing plants to reflect more light than unhealthy plants. Leaf and chlorophyll an role showing growth health tea Remote sensing consists collecting information about objects features without contacting equipment. The Normalized Difference Vegetation Index (NDVI), one first remote analysis products used simplify complexity multispectral imaging, now commonly index botanical assessment. inconsistencies NDVI depending on sensor-specific spatial spectral resolutions. Different parts leaf discolored spots due conditions or nutritional stress, so there values leaf. Unhealthy low NIR disease, insects, sunburn, which damage chloroplast structure leaves, weaken absorption appropriate band, increase reflectance. There difference between measurement results spectrometer sentinel image. This fact Sentinel-2 image can only retrieve pixels with resolution diseased parts, as use spectrometer, directly extracts value infected area normal plant
