Effects of different water tensions on soil applied in two phenological stages in pea (Pisum sativum L.) crop were evaluated in two experiments, both carried out in a completely randomized experimental design with four treatments and four repetitions. The treatments consisted of four different water tensions in soil: 15, 30, 60 and 120 kPa. The results showed significant differences for total production of the plant, for number of beans per plant and for mean weight of the bean, independently of the phenological phase in which the treatment of tension of water was applied in the soil; larger production decrease were observed in reproductive phase, showing that this one is more sensitive to water tensions in soil; the highest production was obtained with irrigation carried out under 15 kPa tension.
