- Abstract
Aiming to study the effects of the available soil water for plants and nitrogen fertilization on sunflower water consumption and efficiency, an experiment was carried out on an area of the Federal University of Paraiba – UFPB, at Lagoa Seca – PB. The study was conducted in a 5x4 factorial with randomized blocks and four replications using the hybrid sunflower Helio 360 submitted to five irrigation depths (40, 55, 70, 85 e 100 % of the Reference Evapotranspiration) and four nitrogen doses (25; 50; 75 e 100 kg ha-1). The data was analyzed through analyses of variance using the F test and regression analyses. The increased available soil water for plants, associated with increasing doses of nitrogen increased significantly the sunflower productivity and oil content of the seeds.
