Abstract

The objective of this research was to estimate the probability of the rainfall supplying the hydric demand of rice considering thirteen 5-day-interval. The probability of hydric supply was determined using a function with gama reduced distribution. The means of the maximum, minimum and average of hydric supply detected were: initial phase, maximum of 35 ± 7%; minimum of 0 ± 4% and average of 16 ± 5%; vegetative phase, 34 ± 10%; 2 ± 2% and 11 ± 5%; in the reproductive phase, 21 ± 4%; 0 ± 1% and 8 ± 2%, maturation phase, 34 ± 4%; 1 ± 5% and 16 ± 3%. With sowing simulations occurring in between the first 5-day-interval of September to November, the hydric supply observed was low.
