The coconut palm responds well to summer irrigation. Under west coast conditions, 2 cm irrigation through perfo-sprays once in 5 days during December-February and once in 4 days during March-May has been found to be beneficial in increasing yields in sand)` loam soil. .Where basin irrigation is practiced; 2001/palm once in 4 days will be beneficial. In areas where water is scarce, soil is sandy and labour is costly, drip system of irrigation can be adopted. The quantity of water recommended for drip irrigation is 66 per cent of the open pan evaporation which comes to 30-321/palm/day during summer months (for a basin area of 1.8 m radius). In the drip irrigation system, microtubes are better than emitters in areas where the clogging problem is acute.
