Resumo

The suitability of an irrigation system depends on the availability and quality of the water, the chemical, physical and physical-water characteristics of the soil, the agronomic requirements of the plants and the local atmospheric conditions. The present study aims to develop irrigation systems technologies in the organic production of 'Pacovan' banana in the Açu-RN Valley region and determine the infiltration of water into the soil in different management systems, seeking technical, social and environmental viability , In addition to providing the interaction between education, Research and Extension. The experimental design was randomized blocks with sub-divided plots and with eight replications, the blocks being represented by four irrigation systems: sprinkler, drip and micro-sprinkler alternative and alternative. The sample space was 32 plots and each plot occupied an area of 144 m2, including 24 clumps of banana trees in the spacing 4 x 2 x 2 m. The planting was carried out during the month of December 2010, the harvest began in January 2012, having already harvested all production of plants mothers, daughters and grandchildren. The productivity parameters of banana fruits and the speed of infiltration of water in the soil were evaluated. It was verified that the sprinkler irrigation system presented the best relative yield in the average weight of the bunches with 14.78 kg, average length of the fruits with 15.46 cm and yield of 24.63 megagrams ha-1. The best infiltration rate was 9.27 cm and the water infiltration velocity in the soil was 2.01 cm h-1 in an area with native forest
