INFLUÊNCIA DAS ADUBAÇÕES ORGÂNICA E MINERAL NA FAUNA EDÁFICA EM LUVISSOLO CULTIVADO COM GERGELIM

Abstract

The objective of this research was to evaluate the abundance, diversity and uniformity of soil macrofauna under the influence of organic fertilization with goat manure compared to NPK fertilization on 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 (EMEPA), approximately 2.0 km away from the city. The design was randomized blocks with treatments: T1: goat manure as organic source in BRS 196 (CNPA G4), T2: goat manure as organic source in BRS Seda, T3: mineral fertilization with NPK in BRS 196 (CNPA G4), T4: mineral fertilization with NPK in BRS Seda, T5: No fertilization in BRS 196 (CNPA G4) and T6: No fertilization in BRS Seda with these fertilizers based on soil analysis, totaling 24 experimental units. In evaluation the ecological behavior of soil macrofauna, measured as the total number of individuals (abundance) and riches of faunal groups and communities comparisons were made using the Shannon biodiversity (H) and Pielou uniformity (e) indexes. The treatments with organic manure were more abundant and rich as well as the faunal group Hymenoptera had the highest abundance and lower diversity and uniformity, regardless of the experimental treatments and samplings. The treatments did not influence the diversity and uniformity of soil macrofauna.
