Abstract: Production of taro (Colocasia esculenta) throughout the Caribbean Basin has been drastically reduced as a consequence of the taro leaf blight. Traditional variety Lila (known as Bun Long in Hawaii) is very susceptible to the blight. In the short term there is interest in the production of Lila under drip irrigation, a system under which blight incidence tends to be lower. The objective was to provide practical information in regard to growth, yield, corm quality and the minimum irrigation requirement for taro Lila grown under upland conditions and under the presence of the blight. Three irrigation treatments were evaluated: rainfed and supplemental irrigation based upon Class A pan factors of 1.0 and 1.3. Providing Lila with supplemental irrigation of at least 1.0 ET resulted in increased growth. Irrigation was non significant for stand. There were no differences for corm fresh weight, nor in plant dry weight or harvest index between plants subjected to 1.0 and 1.3 Class A pan factors. This study suggests that to obtain a Lila crop under upland conditions and under the presence of the leaf blight water to be applied by irrigation should replace at least that lost through évapotranspiration.
