Agalawatta, 1993) Rodrigo, V.H.L.; Herath, P.H.M.U.; Nugawela, A.Use of rainguards can minimize the loss of tappping days and hence the loss in rubber crop. A simple model was developed to study different components determinig the profitability of using rainguard is discussed. Price of rubber, yield potential of a plant and tapping wage rate were identified as most important factors which determine the worthiness of the use of rainguards. Sealent price is also a major factor in deciding profitability. If the price of scalent is less than Rs. 20/= per kg, the profilability from both the apron and the gutter types is sameItem Local knowledge in rubber (Hevea brasiliensis) farming systems in Sri Lanka. applications and constraints(Rubber Research Institute. Agalawatta, 2010) Senevirathna, A.M.W.K.; Pathirana, P.D.; Rodrigo, V.H.L.; Sinclair, F.L.
