Integração do zoneamento agrícola de risco climático-zarc e o calendário biodinâmico na previsão de plantio da cultura do feijão macassar no cariri oriental paraibano

Abstract

The Cariri Oriental Paraibano region, characterized by erratic rainfall patterns, seeks promising alternatives to enhance food security and strengthen family farming practices. Macassar bean (Vigna unguiculata), a drought-resistant legume rich in protein, emerges as a viable option. This research aimed to evaluate the feasibility of cultivating macassar bean in the region, utilizing tools such as the Agricultural Climate Risk Zoning (ZARC) and the Biodynamic Calendar. Data analysis from twelve municipalities identified the most suitable planting periods, considering climatic risks and favorable planting days. The study's findings demonstrate a significant overlap between the favorable days indicated by ZARC and the Biodynamic Calendar, reinforcing the viability of using these tools in conjunction to guide farmers. Regarding planting risks, a predominance of 20% was observed in all municipalities studied, regardless of soil texture. The study's conclusions suggest that macassar bean presents a promising alternative for the Cariri Oriental Paraibano region, contributing to local food security. The adoption of ZARC and the Biodynamic Calendar, along with the selection of appropriate varieties, can optimize productivity and strengthen family farming in the region.
