Irrigation and drainage in pineapple crop (cultivar MD-2) in Ciego de Ávila province

Abstract

The pineapple cultivar MD-2 was introduced in Cuba at the end of the year 2009 and the results obtained in the irrigation in Ceballos Agroindustrial Enterprise have not been satisfactory, being presented manifestations of excess of humidity with the affectation to the crop. With a view to value the conditions of management of the water under the given conditions and to propose the corresponding measures, a study of the irrigation and drainage conditions was carried out in the areas studied and the evaluation of the exploitation of the central pivot machine was carried out according to the NC 11545:2004 and the diagnosis of the problem of the drainage. The results indicate low quality of the irrigation with values of coefficient of uniformity of 66 % and of efficiency of discharge of 71 %. The irrigation system was calculated obtaining 
 for the critical stage with a net norm of 152 m3 /ha and a frequency of irrigation of 7 days, being concluded with the presentation of the technical chart for the adjustment of the module of nozzles and the calculation of the regulation of the machine. It was determined that the hardening of the soil is the main factor that impacts the present drainage problems. There are indicated recommendations on the irrigation technologies, which can be used to develop the crop and solve the current drainage problems.
