Resumo

The aim of this study was to evaluate the abundance and diversity of soil macrofauna under the influence of organic fertilization with goat manure compared to NPK fertilization in a Luvisol with two sesame cultivars. The experiment was conducted in Alagoinha - PB, under field conditions at the Experimental Station of the State Enterprise for Agricultural Research of Paraiba SA (Empresa Estadual de Pesquisa Agropecuária da Paraíba S.A. - EMEPA), approximately 1.24 miles away from the city. The design utilized was in random blocks with the treatment groups: T1: goat manure as organic source in BRS 196 cultivar (CNPA G4), T2: goat manure as organic source in BRS Seda cultivar, T3: mineral fertilizer with NPK in BRS 196 cultivar (CNPA G4), T4: mineral fertilizer with NPK in BRS Seda cultivar, T5: No fertilization in BRS 196 cultivar (CNPA G4) and T6: No fertilization in BRS Seda cultivar, with these fertilizers based on soil analysis, totaling 24 experimental units. In assessing the ecological behavior of soil macrofauna, it was measured the total number of individuals (abundance) and wealth of faunistic groups and communities comparisons were made using the Shannon biodiversity indices (H and equitability of Pielou (e). The treatment groups with organic fertilization were more abundant and rich as well as the faunistic group Hymenoptera had the highest abundance and lower diversity and uniformity, independently of the treatment groups studied and the samplings collected. The treatment groups studied did not influence the diversity and uniformity of edafic macrofauna.
