Dimensões do bulbo molhado em função da vazão do emissor e tempo de irrigação.

Abstract

The knowledge of the wetted bulb in the soil profile is important to optimize the drip irrigation management in agriculture. To evaluate the performance of the wetted bulb using response surface models an experiment was carried out in Entisol in random blocks in split-plot design with three repetitions. The treatments were composed of the factors time and emitter discharge. The discharge rates were of 1, 2, 4 and 8 L h-1 and application time of 1, 2, 4 and 7 h. The results showed that the model of response can be used to estimated dimension bulb.
