Análise da emergência de sementes da algaroba (Prosopis juliflora Sw. D.C.) em esterco equino em área de caatinga no Cariri Paraibano.

Abstract

The aim of this study was to evaluate the potential of seed emergency of Prosopis juliflora Sw. D.C. in horse manure collected in the municipality of Sumé, semiarid Paraiba. The monitoring of the germination process was performed in an interval of 30 days in eight installments of 1.2 m x 0.9 m (1,08m2). For determining dry matter seedlings used the oven method. Emerged in total 1,185 seedlings. The plots with the manure samples were emerged over the 5 and 6 with 224 and 213 respectively. Evaluating the dry matter of seedlings per plot it was observed that it has a significant loss of water in the monitored set, indicating the importance of moving forward on the species studies and the relationship with the Brazilian semiarid systems. Therefore, the data generated in this study are shown of great importance for the understanding of the elements that define the factors emergency of seeds of Algaroba in horse manure, thus indicating instruments relevant to the management of the species considering the principles of sustainability.
