- Abstract
The study of the wet bulb is recommended as part of water management and in the design of drip irrigation systems. The research had the objective of evaluating the dimensions of the wet bulb in soil of medium texture, under irrigation by surface drip, in the initial condition of dry soil, in an area cultivated with sugar apples (Annona squamosa L.) in the state of Roraima. The trees were planted in 3 x 5m spacing and drip irrigated, whose emitters had a nominal flow of 2.0 L h-1 (100 kPa) and spaced 50cm apart. The experimental design was completely randomized with four treatments, given by the irrigation times (0.5, 1, 1.5 and 2 hours), with four replications. The analyzed variables were surface diameter, maximum diameter and maximum depth, in the trench method. The application time had a significant effect on the surface diameter, larger diameter and the maximum depth, obtaining equations representative of the phenomenon. The percentage of wet area was unsuitable for the plants, under the studied conditions.
