| description | Although nitrogen is the most widely used fertilizer in agriculture, it contaminates the surface and groundwater through leaching. A decrease in the concentration of total nitrogen and changes in the ammonium:nitrate ratio can provide information for a better use of this nutrient. The objective of this study was to evaluate the effect of a decrease in total nitrogen and an increase in the percentage of N-NH4+ on indicators of growth, productivity, quality and nitrogen use efficiency (NUE) in carnation cultivation. In the Centro Agropecuario Marengo at the Universidad Nacional de Colombia, two concentrations of total nitrogen were evaluated (200-140 mg L-1 in the vegetative phase and 160-112 mg L-1 in the productive phase) with three ratios of N-NH4:N-NO3 (5:95, 15:85 and 25:75) in standard carnation plants cv. Don Pedro grown in substrate. In both fertigation formulas, similar productivity and qualities were obtained, and the formula with less total N provided better NUE, mitigating the negative impact of this nutrient on the environment. Likewise, the ammoniacal component played a preponderant role: the number of floral stems per plant decreased as the ammoniacal component increased, similar to that observed with the percentage of flowering stems in the ‘Select’ quality grade. |

Aunque el nitrógeno es el fertilizante más usado en la agricultura contribuye a contaminar aguas superficiales y subterráneas a través de su lixiviación. Una disminución en la concentración del nitrógeno total y cambios en la relación amonio:nitrato pueden proveer información acerca de una mejor utilización de este nutriente. El objetivo de este estudio fue evaluar el efecto de la disminución del nitrógeno total y el aumento del porcentaje de N-NH4+ sobre indicadores del crecimiento, la productividad, la calidad y la eficiencia del uso del nitrógeno (EUN) en el cultivo de clavel. Para lo cual, en el Centro Agropecuario Marengo de la Universidad Nacional de Colombia se evaluaron dos concentraciones de nitrógeno total (200-140 mg L-1 en fase vegetativa y 160-112 mg L-1 en fase productiva) con tres relaciones de N-NH4:N-NO3 (5:95, 15:85 y 25:75) en plantas de clavel estándar cv. Don Pedro sembradas en sustrato. En ambas fórmulas de fertirriego se obtuvieron productividades y calidades similares y en aquella fórmula con menos N total mejor EUN, mitigando el impacto negativo de este nutriente en el medio ambiente. Así mismo, el componente amoniacal juega un papel preponderante: el número de tallos florales por planta disminuiría en la medida que se aumenta el componente amoniacal, de manera similar a lo observado con el porcentaje de tallos florales en grado de calidad Select.
