Resumo: 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.

A probabilidade de atendimento hídrico foi determinada usando-se função com distribuição gama reduzida. As médias das probabilidades máxima, mínima e média de atendimento hídrico foram: fase inicial, máxima de 35 ± 7%; mínima de 0 ± 4% e média de 16 ± 5%; na fase vegetativa, 34 ± 10%; 2 ± 2% e 11% ± 5%; na fase reprodutiva, 21 ± 4%; 0 ± 1% e 8 ± 2%, e fase de maturação, 34 ± 4%; 1 ± 5% e 16 ± 3%. Com a simulação de semeaduras entre o primeiro qüinqüídio de setembro e de novembro, conclui-se que a probabilidade de atendimento hídrico é baixa.Universidade Estadual de Maringá2007-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/26810.4025/actasciagron.v29i2.268Acta Scientiarum.
