Desempenho hidráulico e manejo da irrigação em sistema irrigado por microaspersão

In irrigation is important for quantifying the volume of irrigating water for the plant and the time required for the correct application of water, thus making the appropriate management of irrigation. Considering this, the present study was to evaluate the hydraulic performance and management of microirrigation in area of 5.9 hectares to the cultivation of papaya irrigated perimeter Araras Norte, located in the municipalities of Reriutaba and Varjota, State of Ceará . For the evaluation were collected hydraulic flow and pressure of microsprinklers following the methodology suggested by DENICULI et al., (1980). For monitoring the management of irrigation were used two batteries of tensiometers, in addition to lifting the number of daily hours of operation. It was observed that the management of irrigation was not performed properly, because even with an efficiency of application considered good, there was also a considerable loss by percolation, which can cause an imbalance water.
