Edited by Sumit de Silva 539-554http://hdl.handle.net/123456789/2656Economic evaluation of some of the promising coconut based farming system models was carried out at CPCRI with the 1988-89 factor-product costs to show the potential for resource maximization and enhancing net return from lands planted to coconut by adoption of farming systems approach. Feasibility studies under rainfed coconut gardens involving different crop species and varieties as intercrops revealed that the tubers and rhizomatous crops were relatively more remunerative components in the systems than that of cereals, pulses and oilseeds. The economic potential in terms of net profit in the case of coconut + amorphophallus system was worked out as US $ 1160 /ha/year and in the case of coconut + ginger system it was US $ 896 /ha/year, while coconut monocrop under similar situation gave a net return of US $ 319.enArticle
