Data for predicting chlorophyll content in sugarcane crops

A study was conducted in a sugarcane field located at the Sugar Research Institute (SRI), Udawalawa, Sri Lanka, with various fertiliser applications over the entire growing season from 2020 to 2021. An unmanned Aerial Vehicle (UAV) with multispectral camera was used to collect the aerial images to generate the vegetation indices. Ground measurements of leaf chlorophyll were used as indications for fertiliser status in the sugarcane field in this study. The different machine learning (ML) algorithms were developed using ground-truthing data of chlorophyll content and UAV-derived spectral vegetation indices to forecast sugarcane chlorophyll content.
