Lunuwila, 1994-95) Abeygunawardena, P.; Abeyratne, F.; Fernando, M.T.N.Economic feasibility of soil moisture conservation in coconut production using coconut husks and coir dust was examined in this study. The preliminary data for the study were collected from two trials conducted by the CRI along with the several other secondary information. The results of the analysis revealed that calculated benefit-cost rations and Net Present Values are financially and economically acceptable under all the scenaries addressed in this study.

Based on the estimated economic parameters, it is concluded that the efforts on moisture conservation using coconut husks and coir dust in lateritic gravel and sandy soils are economically viable propositions.
