I’m not aware of a spectral library fically on sugarcane; however, a lot of vegetation spectra you can find in the ECOSTRESS spectral library (https://speclib.jpl.nasa.gov/). If you find a suitable library that is not included in the MOOC yet, we’d be happy if you could share it with your fellow students.
Actually, the NDVI can be calculated from multispectral imagery – you could most probably find Landsat (https://earthexplorer.usgs.gov/) or Sentinel-2 imagery (https://apps.sentinel-hub.com/eo-browser) over sugar cane fields and calculate the index yourself (?). If you would like to check out other vegetation indices, you can browse the vegetation index database (https://www.indexdatabase.de/db/i.php).
Maybe, our newest MOOC on imaging spectroscopy for agricultural applications is also of interest for you?
All of the above resources are for free, I hope you find something to support your work there.
All the best,
