N2  - In the process of expanding rubber cultivation to the nontraditional areas with drier climate, it is extremely important to find remedies for both biophysical and socio-economic limitations for it. In this regard, intercropping sugarcane with rubber was used as a tool in the present study. Sugarcane was planted in two densities together with immature rubber crop under on-farm conditions in the intermediate zone of Sri Lanka and growth and yield parameters were assessed. The planting density of sugarcane did not affect sugarcane yield per unit length of planting, hence the greatest yield per hectare was given by the highest density tested. Either density of sugarcane had no adverse effect on the growth of rubber, instead intercropped rubber showed an improved performance over the sole crop. Alleviation of radiation stress on photosynthesis by the partial shading given by sugarcane was identified as the factor which governed the better growth of intercropped rubber. Social implications of the rubber/sugarcane intercrop are discussed
