Sumanasena, H.A.; Chandana, G.A. A study was conducted in a two year old stand of betel cultivation, to investigate the effect of three irrigation methods and three fertilizer mixtures on leaf productivity. Leaf production was significantly improved by daily irrigation at 5 mm per day using either manual splash method or drippers. The present departmental recommendation of straight fertilizer mixture proved to be still valid for betel vines.
