What is this page?
This page calculates the optimum number of ratoons grown in a crop cycle that maximises profitability.
Optimum Number of Ratoons
The optimum number of ratoons is identified by the last ratoon that contributes to an increased average annual gross margin per hectare over the crop cycle. Thereafter, additional ratoons will result in a decreased average gross margin, indicating the need to replant.
How to use this page
Calculate the optimum number of ratoons by selecting the cane planting time (early, late or plough-out replant) to be used for the calculation from the drop-down list. Please note that you can only select these options if you have a crop entry for them from the Cane Assumptions page.
The optimum number of ratoons will be shown above the table (on the left) in the light blue shaded area once the planting time has been chosen. In the below example, the optimum number of ratoons is 3 and the average annual gross margin is $1168/ha.
What about additional ratoons?
The optimum ratoons table also includes additional ratoons that have not been entered (e.g. 5th to 10th ratoons). The yield and CCS values for these additional ratoons should be edited (by clicking the pencil icon) by entering estimates that reflect their particular situation.
