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 Scientists arm the rubber plant to successfully conquer the 300M elevation barrier(Rubber Research Institute of Sri Lanka:Agalawatta, 2009) Nugawela, A.Item Enjoy 2000 plus yields. adhere to basic agronomic practices(Rubber Research Institute of Sri Lanka:Agalawatta, 2006) Nugawela, A.Item Rubber - potential yields and strategies to achieve it in traditional and marginal areas(Rubber Research Institute of Sri Lanka:Agalawatta, 2002) Nugawela, A.Item Tapper shortage in Sri Lanka - reasons, repercussions and recommendations to minimize it(Rubber Research Institute of Sri Lanka:Agalawatta, 2000) Nugawela, A.Item How and why the intake of a tapper should be increased(Rubber Research Institute of Sri Lanka:Agalawatta, 1998) Nugawela, A.Item Maximising yields in rubber platations(Rubber Research Institute of Sri Lanka:Agalawatta, 1998) Nugawela, A.Item The effect of girth at opening on yield and growth of modern Hevea brasiliensis Muell Arg. clones(Rubber Research Institute:Agalawatta, 2002) Nugawela, A.; Samarasekera, R.K.; Wilbert, S.
