At the present time, inadequate and unstable water supplies and pest and disease control are the major constraints for rice double cropping in Sri Lanka. The development of low cost, low risk and convenient technology, together with low environment damage, for small rice farmers requires greater attention. Technology which requires considerable financial commitment by small farmers requires in addition an economic evaluation too. Therefore, at this juncture a multiprofessional approach is appropriate for further development of rice double cropping in Sri Lanka involving plant breeders, agronomists, engineers, ecologists and even economists.
