Abstract

An experiment to determine the response of taniers (Xanthosoma sp.) to irrigation was established at three locations in Puerto Rico. Drip-irrigated taniers were grown with different water regimes, where water application was based on tensiometer readings at 15-, 30- and 45-cm depths. Plots were irrigated when soil moisture tension was above 40 cbars. The combined analyses of the data showed that plots receiving the highest amount of water (based on tensiometers at IS-cm depth) yielded significantly higher than plots receiving the intermediate and lowest amounts of water (tensiometers at 30- and 45-cm depths, respectively). At two locations, number of marketable cormels was significantly higher in plots with the high water regime than in the inter immediate treatment. Mean cormel weight was not affected by the irrigation treatments at two locations. Symptoms of dry rot were conspicuous at both locations. The results show that tanier yields can be increased by irrigation even in the presence of dry rot.
