Cane Availability Survey Report 2020/2021 – 2021/2022
The 2020 Industry cane availability survey was undertaken from 7th to 17th December 2020 to establish the cane situation and make projections of its availability for processing into sugar. This was done by 5 field enumeration teams who carried out visual physical assessment of cane to estimate the expected yields. A productivity index ranging between 0 and 4 was applied to cane crop from the age of 3 months for crop vigour, crop colour, crop density, effects of weeds and impact of pests and diseases infestation to yield.
Summation of the scores was used to estimate zonal productivity using threshold yields of 100, 90, 80 and 70 tonnes per hectare for plant crop, ratoon 1, ratoon 2 and ratoon 3 respectively. Projected production was estimated by multiplying the available cane area by average productivity for the specific catchment. Constraints to cane production such as inadequate availability of resources for cane development among others were identified and possible mitigation measures proposed. Field data capture was done using a mobile aided application Survey123 for ArcGis that improved on speed of flow of data between enumerators and the office, error tracking, actual location using GPS etc. The resultant report is used in planning and in providing advisory services to stakeholders.
