Spatial-temporal distribution of Albizia procera in sugarcane plantations in Cuba

Abstract

The work was carried out with the objective of determining the spatial and temporal distribution of Albizia procera (Roxb.) Benth species in sugarcane areas in Cuba. For this purpose, the information contained in the database generated by the weed identification surveys carried out in the period 2016-2020 by the Integral Weed Control Service (SERCIM) of the Instituto de Investigaciones de la Caña de Azúcar (INICA) was used. The surveys were conducted by the visual method, walking the field along its diagonals, with the use of manuals or catalogs in digital or printed format. The magnitude of the infestation was evaluated through the frequency and area infested. The results showed that in the period 2016-2020, the species presented frequency values in the Accidental category, with an increasing trend. The highest frequency was found in the western region and the largest plagued area in the central region. The surveys evidenced the presence of this species in all stages of the development and harvest cycles of sugarcane. It is recommended that a management strategy be developed to help reduce infested areas.
