Abstract

CROPWAT 8.0 model was used to estimate the water requirement of pineapple for the 2021/22 cropping period, considering all the months in the year. This was done to ascertain which months in the year have lower irrigation water requirements and where water savings can be made. For the months of December to August, irrigation requirement (mm) of 140, 145.1, 113.3, 110.8, 110.9, 145.9, 107.6 and 114, respectively was determined at the study site. However, sucker planting in September, October and November has shown requirements (mm) of 72.8, 61.3, 61.4 respectively, and adjusting the planting calendar to accommodate these months is recommended.
