Spatial variation of sugarcane productivity in the tully mill district: is it worth worrying about?

摘要

There are currently seven sub-districts within the Tully mill area. Block productivity information is currently used to provide area specific recommendations to growers in each of these sup-districts. This is done on the basis that these sub-districts behave differently in response to a range of agronomically important characteristics such as soil type and climate that may warrant different management strategies. The hypothesis that sugarcane productivity varies significantly between sub-districts was tested using 12 years of block productivity data for cane yield and CCS from the six sub-districts where long-term data were available.
