Levantamento fitossociológico de plantas invasoras em cultivos de palma forrageira e milho

Abstract

Research related to the identification of invasive plants is so far unknown for the culture of cactus in the semi-arid northeast. Therefore, the present study aimed to evaluate the weed community under different cultivation conditions through a phytosociological survey. The experiment was carried out in an experimental area located at the Universidade Federal Rural de Pernambuco, which has been cultivated with forage cactus (Orelha de Elefante Mexicana) and vip ferocious hybrid son, distributed in six treatments: exclusive cactus with and without mulch; palm intercropped with corn with and without mulch; and the condition of exclusive corn with and without mulch. Based on the data obtained, the following phytosociological parameters were calculated: frequency; relative frequency; density; relative density; abundance; relative abundance; and the importance value index. There was a need for greater attention in the area for the management of the poaia-rasteira (Richardia grandiflora (Cham. & Schltdl.) Steud.), which obtained the highest frequencies and importance value index in most conditions of cultivation
