dc.descriptionDespite numerous studies conducted in Brazil on nitrogen fertilization in common bean, there are still many questions about the doses and timing of nitrogen (N) application in the crop, mainly regarding late nutrient application and its effect on grain yield and quality. This study aimed to quantify the effect of late additional N application on grain yield and their components, and on grain quality of common bean, irrigated by a central pivot in a no-tillage system. The experimental design was a split-plot, with five replications. The treatments consisted of the combination of four N managements, involving doses and application stages (Management 1: 70 kg ha-1of N (V3) + 50 N (V4), Management 2: 70 N (V3) + 50 N ( V4) + 50 N (R6), Management 3: 70 N (V3) + 50 N (R6), and Management 4: 70 N (V3) + 50 N (V4) + 50 N (R7)), with seven common bean cultivars/lines (1. BRS ELO FC423, 2. BRS FC104, 3. BRS FC409, 4. BRS FC416, 5. CNFC 16484, 6. CNFC487, and 7. CNFC 16729. The CNFC 16484 and CNFC 16497 lines and the BRS FC 416 cultivar were the most productive ones. The late additional N application contributed to increasing pods per plant and also improved grain quality, evidenced by the higher percentage of grains retained in Sieve 12 and the higher N content in the grains, which means higher protein content.
