Prediction of sugarcane sucrose content with high resolution, hyperspectral leaf reflectance measurements [Full subscriber]

Remote sensing for crop maturity parameters may offer sugarcane producers a method to develop harvest schedules that maximize sucrose production. Several tests were conducted to determine if leaf reflectance measurements could be used to predict theoretically recoverable sugar (TRS) levels (crop maturity) prior to harvest. Leaf samples were collected from multi-variety first-ratoon (FR) sugarcane maturity studies in 2005 at three sample dates and from the plant-cane (PC) and first-ratoon (FR) sugarcane maturity studies throughout the 2006 September through December harvest season. Sugarcane juice was analyzed for its Brix, and sucrose content to predict TRS and leaf reflectance measurements were taken…
