A particular multipurpose cropping model was established at Delpitiya of Gampola, Sri Lanka in November 1979 in one hectare of absolutely eroded abandoned tea land on experimental basis. This study was carried out to assess the performance of this cropping model during 2004-2011. Soil loss was measured by installing physical soil erosion measuring units. Technical purpose of multipurpose cropping model was estimated to identify the potential increase in productivity of marginal tea lands which have been becoming serious environmental, social and ecological hazards in mid country of Sri Lanka. The system urged to compare and analyze with and without project benefits. The results showed that soil loss on multipurpose cropping model came down to only 2 tons after its 8th year. But soil loss without project (old seedling tea field) went up to 61 tons per hectare at its 8th year. There was almost 31 times less erosion than without projects. The model shows higher values of cost benefit ratio (12.92), net present value (Rs. 1582976.33) and internal rate of return (40.20%) to confirm economic viability of the system.
