To meet the ever-growing demand of sugar, a great focus has to be given to its input, which is a sugar cane crop,
and management of the crop’s water requirements. This study was initiated with the objective of estimating and
mapping the spatiotemporal variability of ratton sugar cane (Saccharum officianarum) crop water requirements at the
Arjo-Dedessa sugar factory and nearby areas. Arc GIS 10.4.1 and CROPWAT 8.0 software were the materials used.
Fourteen meteorological stations were delineated, and data from ten stations were used for analysis. The measured
data and predicted value proved the geostastical tool’s applicability. According to the mapping, the annual crop
water need varied from 1296.5 millimetres to 1752.36 millimetres using the inverse distance weighting method. The
apparent regional variation in the yearly water need of sugar c.. View more»
