Dinâmica da produção de palma forrageira no cariri oriental paraibano

Abstract

The forage cactus due to its rusticity and production potential in low rainfall has become a relevant resource for animal feed, especially in semiarid regions are the most vulnerable. In view of this problem, the present work proposed to evaluate the dynamics of forage cactus in the municipalities of the Eastern Cariri, associating the results obtained with the local animal breeding patterns and rainfall. The data used were obtained from the Agricultural Census 2017, provided by the Brazilian Institute of Geography and Statistics (IBGE), using the Automatic Recovery System (SIDRA) and the rainfall values through the Executive Agency for Water Management of the State of Paraíba (AESA). The statistics proposed to analyze the influence of the variables on the production of forage cactus culture in the Eastern Cariri was a correlation matrix and a descriptive analysis of main components (ACP). The correlation matrix showed a strong positive correlation between the number of agricultural establishments and the production of cactus, as well as with the harvested area of cactus. There was a positive correlation between the production of cactus and the area harvested and the breeding of cattle. The pluviometric precipitation had a negative correction with the creation of goats and sheep. The analysis of main components registered 81.67% of explanation of the original variance in the first two axes and demonstrated a strong association of cactus production, with cattle breeding, harvested area and agricultural establishments, as well as the strong relationship between breeding and sheep and goats. In this way, cattle breeding in the municipalities of Cariri Oriental proved to be strongly linked to the dynamics of decato production and the low rainfall in the municipalities allows for a trend in sheep and goat farming.
