Giralt E. Influence of soil moisture level on the taro crop yield.
Research Institute of Irrigation and Drainage. Technical Report, 1982, La Habana, Cuba.
The water requeriments of the taro variety Islander Japanese on a Ferrallitic red soil at the Experimental Station of Irrigation and Drainage in Havana province was studied. It was recommend irrigate at 0.30 m depth from planting until the closure of the field and 0.40 m the rest of the growing season. The optimum soil moisture is reached when irrigate to 80% of field capacity obtaining satisfactory yields.
No significant differences in yields if the soil moisture drops to 70% of field capacity in the period between germination and the closure of the field, allowing to extend the irrigation interval. From the closure of the field is necessary to raise the minimum soil moisture at 80% of field capacity for to get acceptable yields. The annual water requerements vary from 600 to 932 mm. Most taro crop water demand is between June and August, with an average evapotranspiration of 6.5 mm / day for this period.
