Abstract
The water requirements of arecanut palm {Areca catechu L.) in the coastal tracts of Karnataka were estimated based on the evaporative demand of the crop. The crop-water demand was evaluated by using the crop-coefficient and the potential evapo-transpiration values. The potential evapo- transpiration values for the region were computed by modified Penman method using a computer programme on monthly and weekly basis for 1971-85. The depth and quantity of water, the frequency of irrigation and the total number of irrigations required varied from month to month. The requirement of water was more during March-May in arecanut than during other months.
