Economic Injury Level of Canjiqueira in Native Pastures in Pantanal of Nhecolândia

Abstract

Pantanal plain has large extensions of land formed by many types of landscapes suitable to extensive livestock system. Open grasslands and lowlands are formed by forage such as grasses and forbs widely consumed by cattle. However, climatic and human factors can promote the dissemination of invasive shrub species such as canjiqueira (Byrsonima cydoniifolia A. Juss) making it necessary, in many cases, the human intervention to control the invasion. The present work had as objective to determine the economic threshold level to control canjiqueira through two methods: tractor driven blade and link chains pulled by tractor in different invasion levels plants per hectare. Economic Threshold proved to be a tool for efficient and effective management for making decisions of when and how to do the control of canjiqueira in natural pastures of Pantanal of Nhecolândia.

Fenologia, Polinização E Frugivoria De Myrtaceae No Pantanal

“…A pecuária de cria, recria e engorda é a atividade econômica dominante no Pantanal (KAWAKAMI DE RESENDE, 2008; PAULON GIRARDI; CARMEM ROSSETTO, 2011), onde o uso do solo é basicamente com forrageiras como gramíneas e herbáceas nativas para o consumo bovino (BERSELI et al, 2019;SPECHT, 2011). Cabendo aqui destacar que o manejo do gado é regido pelo ritmo das inundações anuais (ARAUJO et al, 2018), com dois períodos críticos devido as restrições alimentares impostas pelo pulso: um do meio ao final da cheia (fevereiro a maio) e outro do meio ao fim da seca (POTT; CATTO; DE BRUM, 1989).…”
