Abstract

This study was undertaken to verify the effects of fertilizer, cultivar and weed control techniques in sesame (Sesamum indicum L.). The experiment was conducted in a Non-Calcic Brown soil at Patos county, located at "Seridó" region in the state of Paraíba, Brazil. Eight treatments including fertilization, cultivar and weed control techniques were tested. Seed yield for both cultivars was about the same, having an average of 672 kg/ha. There was an increase of 45% in seed production due to fertilizer (30-30-0). Diuron herbicide and hoeing had similar results by showing good selectivity and a high control of weeds. It was observed that fertilizer and hoeing increased the weed competition which did not occur with diuron treatment.
