Net photosynthesis rate of sour passion fruit cv. BRS GA1 irrigated with water depths in the soil with different doses of water-retaining polymer (a) and cultivated in pit volumes in the soil with different doses of water-retaining polymer (b). Means with same lowercase letters in (a) do not differ in irrigation depths of 70% and 100% ETc within same dose of water-retaining polymer according to the Tukey test at 0.05 probability. Means with same lowercase letters in (b) do not differ in pit volumes of 64 dm3 and 128 dm3 within the same dose of water-retaining polymer according to the Tukey test at 0.05 probability.
