Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2019, Vol 14, Issue 2
Abstract
In view of the importance of the cultivation of cowpea in the semi-arid regions of the Brazilian Northeast and the need to know the behavior of the occurrence of summer, due to its importance for rainfed agriculture, the objective of this study was to classify the influence of summer the productivity of cowpea in the municipality of Crateús, Ceará, from 2006 to 2016. Data were collected on cowpea productivity and rainfall data for the first crop, provided by the Brazilian Institute of Geography and Statistics (Municipal Agricultural Production) and Fundação Cearense de Meteorologia e Recursos Hídricos, respectively. The results indicate that the most frequent type of summer in the region during the studied period was type A, with more than 70 occurrences. The type B and D of summers showed a significant correlation between the yield of bean and cowpea beans in the first harvest for the municipality of Crateús, and it is necessary to take into account the months that this distribution occurs more frequently, measures to mitigate their harmful effects.
