A field study was carried out, during two years, on a Ferrallitic soil, for determining the response of covered dark tobacco cv. Corojo to sprinkler and traditional irrigation methods. No significant differences were noted for production values after seven water applications, totalizing 1686 m3/ha (Overall average for the different methods), when the total value and those for the different leaf-yielding tobacco categories were analyzed for the different irrigation methods: sprinkler under the cheesecloth (12889 $/ha), sprinkler over the cheesecloth (12242 $/ha) and hose irrigation (12017 $/ha).
Mean evapotranspiration for covered dark tobacco during 84day period was 223 mm. The year had a great effect on total yield (kg/ha) and on the groups of tobacco categories and production values, when they were compared during the study; were obtained yields of 2047 kg/ha-546000 leaves/ha and 1954 kg/ha-530000 leaves/ha for the 1971-1972 and 1972-1973 seasons, with production values of 13619 and 11146 $/ha respectively.
