Irrigation and Drainage Series Vol. 9, No. 2: 59-70, 1986.Cuba.
A comparative study was conducted during three years of irrigation in the period 1982 to 1985, in the Crops Enterprise Melena del Sur of Havana province on the determination of irrigation timing in the potato crop. It was used 3 methods: the gravimetric as a witness, the bioclimatic using evaporímeter Class A and the tensiometers.
The results show that the methods studied can serve to prognosticate irrigation timing, the method bioclimatic was the better one and the must simple of all, where there was a significant correlation with the gravimetric method with a value of r = 0.99, the differences between reserve moisture values were 20 m3/hectare.
