Resumo:The availability of water of quality has become worldwide, a major constraint to expanding agricultural frontiers. Within this context, this study aimed to evaluate the effects of boron doses and irrigation with two types of water, wastewater and municipal supply water, on yield components of sunflower (Helianthus annuus L.) cv. EMBRAPA 122/V-2000. The study was conducted in a greenhouse at the Federal University of Campina Grande, in a randomized block design, analyzed in a 5 x 2 factorial with five B of boron (0; 1.0; 2.0; 3.0 and 4.0 mg L-1) combined with two types of irrigation water (R - wastewater and AB - municipal supply water) with three replications. Statistical analysis consisted of analysis of variance (F test) and means were compared by Tukey test to compare qualitative factors at 0.05 probability. It was found that the boron levels and types of water did not affect any varieble related to production of seeds, however, irrigation with wastewater variables positively influenced the fresh and dry leaves, stem and shoot all related to forage production.
