The present study was conducted in the experimental area of the State University of Goiás, University Unit Santa Helena de Goiás, aiming to evaluate features in the growth, development, production culture of okra and efficiency of water use under different irrigation due to the evaporation tank in Class A. The treatments consisted of five percentages of Class A pan evaporation (ACE), as follows: 0. 50, 75, 100 and 125%. Sowing June 26 was performed, and the transplant took place on July 12, 2012. Data were collected between August 25, 2012 to October 15, 2012. Irrigation management was carried out starting from a Class A tank installed within the experimental area. The slides were applied using a system of drip irrigation located, with a flow rate of 1.7 L h-1 subjected to a pressure of 9 MCA service. We used a fixed irrigation for 1 day. The parameters evaluated were: average fruit diameter, average length of the fruit, number of fruits per plant, Productivity and Efficiency in water use by the crop. - The application of different irrigation had a significant influence on vegetative, reproductive development of the culture of okra. The blade 50 % of ECA showed greater efficiency in the use of water in the cultivation of okra. The best fit linear model to a set of parameter data, average number of side shoots, it is no need to further test strip to determine the maximum recommended blade. The depth of irrigation that delivers the highest productivity was 102% ECA
