Leaf area index (LAI) is one of the important variables for crop growth monitoring and yield estimating. In this article. the potato LAI was retrieved by several vegetation indices (VIs) and spectral parameters of the continuum removal method (SPCRM) to provide accurate estimates. A comparison of the two methods of retrieving precision was completed. https://fitnessgravesyardes.shop/product-category/front-sar-pad/
