Abstract

CROPWAT is a widely accepted model for calculating crop water requirement. In the present study an effort has been made to calculate the crop water requirement and irrigation scheduling of banana for two seasons in Manali watershed in Thrissur district of Kerala using CROPWAT 8 model. The climatic data for a period of 30 years (19882018) were collected from KAU, Vellanikkara, Kerala. Secondary data sources were consulted to obtain data related to crop and soil. The crop water requirement of banana was found to be 1, 063.5 and 1, 144.5 mm/dec for rainfed and irrigated crop respectively. The irrigation requirement of rainfed and irrigated banana crop was found to be 499.8 and 700.1 mm/dec respectively.
