Banana yield under different uniformity of water distribution at the Distrito Irrigado do Baixo Assú, Rio Grande do Norte, Brazil

Abstract

To evaluate the banana yield under different uniformity of irrigation depths, a study was carried out at the “Distrito Irrigado do Baixo Assú” (DIBA), Alto do Rodrigues, Rio Grande do Norte State, Brazil. The data distribution uniformity of the irrigation system were collected in different plots at the project-DIBA aimed to estimate productivity maxima and water demand of the banana, being used the software “Sistema de Suporte a Tomada de Decisão na Agricultura” (SISDA). The results showed that the high sensitivity of the combined model requiring high uniformity to estimate the crop yield culture with accurately. It is required the adaptation of the irrigation system and application technique for appropriate management and to increase of the water  application uniformity and, consequently, to improve the yield culture.
