A field investigation was undertaken under All India Coordinated Research Project on Palms at Agricultural Research Station, Mulde in Sindhudurg district of Maharashtra since 1989 to assess the feasibility of growing oil palm in Konkan region and to assess the fertilizer and irrigation requirement. Five years pooled data from 12th to 16th year after planting revealed that oil palm showed high degree of response to fertilizer and irrigation. Irrigation by drip system with a discharge of 70 l of water per day during post monsoon season and by giving NPK fertilizer @ 1200:600:2700 g per palm par year secured the total returns of Rs. 75,775 (with the FFB rate of Rs. 3,500/ t) with a benefit cost ratio of 1.86 over rain fed condition. In the present study, cultivation of oil palm with basin irrigation at 560 l of water at an interval of four days from cessation of monsoon along with NPK at 1200:600:2700 g per palm par year recorded total returns of Rs. 69,615 with benefit cost ratio of 1.74 over rainfed crop. Cultivation of oil palm under rainfed condition along with same fertilizer level earned total returns of Rs. 44,450 with benefit cost ratio of 1.0 and cultivation of oil palm as rainfed crop without fertilizer was not a profitable proposition. Based on the study, it is recommended that cultivation of oil palm under irrigation (either by drip or through basin) along with a fertilizer dose of 1200:600:2700 g per palm per year is beneficial under Konkan conditions.
