dc.description.abstract | Sunflower (Helianthus annuus L.) conventional (CONV) and high oleic (HO) genotypes differ in yield and quality. Nitrogen affects grain yield, quality, and by-products protein concentration. The objective was to evaluate the effect of genotype and N on grain yield, oil (OG) and protein (PG) concentration in grain and in by-products (PM). The effect of genotype was evaluated in Exp. 1 with 7 CONV and 7 HO hybrids, at two planting dates (PD early and late). The effect of N (Exp. 2) was evaluated in 10 locations (3 with CONV and 7 with HO), under six N rates (0, 30, 60, 90, 120, and 150 kg N ha–1). We determined yield, OG, PG and PM . For the early PD of E1, yield was higher in HO than CONV genotypes (3822 kg ha–1 vs. 3495 kg ha–1). In Exp. 2, N increased yield in 50% of the locations (HO: 586; CONV: 597 kg ha–1). In Exp. 1, genotype did not affect OG, but PG was higher in HO than in CONV ones (18.0 vs. 16.8%, respectively). In Exp. 2, N did not affect OG, but increased PG in both types of genotypes. Consequently, PG/OG ratio increased with N rates. The higher PG, was also reflected in higher PM (44.0% HO and 38.8% CONV, respectively). Increases of 2.5% points in PG resulted in increases of 5.6 in PM . Therefore, the application of N would allow obtaining high yields and PG without detrimental effects on OG, improving the quality of grains and by-products. | |
