During 1986-1988 period, agro technical and operative evaluations of sprinkler irrigation system “SDI Modified” were done in the dark tobacco variety Criollo in the Primero de Enero Farm, Mantua municipality, in Pinar del Rio Province. Using the sprinkler MAR-90 Z, spaced 12mx 12m it was obtained by Cristianssen method a coefficient of acceptable uniformity distribution of rain with values from 75 to 94 % for wind speed lower than 4 m/s.
The operative coefficients were determined according normative NC 34-37 for technological and technical safety and by use of productive time with values of 0, 954; 0, 986 and 0, 86 respectively. The productivity for a partial net water requirement of 311 m3/ha, was 0, 19 ha/ hour for the net irrigation time and 0, 16 ha/hour for productive time.
