Woody, exotic and invasive species in sugarcane areas of the Guantanamo province.
The sugar cane massif of the Argeo Martínez Sugar Company in Guantánamo province is affected by the woody species Dichrostachys cinerea (L.) Wight & Arn (marabou) and Leucaena leucocephala (Lam.) De Wit. (leucaena), those that invade sugarcane plantations in the territory, sharing living space, water, light and nutrients while making harvest difficult. In order to determine the degree of affectation and frequency of appearance of the woody, exotic and invasive species D. cinerea and L. leucocephala and to represent the spatial distribution, the study was carried out in the sugarcane areas based on the weed survey of the PCMalezas between the years 2006-2018. The results of the frequency of appearance showed that these species are scattered in 96 blocks of 8 producing units, distributed in 2,723.09 ha of sugarcane with a predominance of the degree of slight affectation and number of incidence as weeds. 4. The statistical analysis of the frequency of appearance, showed a significant difference between the species of woody plants. It was observed in the spatial distribution, that the northwest and southeast region of the sugarcane agricultural area presents a higher incidence of invasion of the species studied.
