| description | Background and Aims: The biological fixation of nitrogen (BFN) in legumes native to Mexico has been little studied; particularly in species of the genus Lupinus there is no information about this. Therefore, the objective of this investigation was to evaluate the BFN in three wild lupins from the state of Jalisco, Mexico (Lupinus exaltatus, L. rotundiflorus and L. mexicanus) in terms of the amount of N fixed (kg ha-1) and the N proportion derived from the atmosphere (% Ndfa).Methods: The species under study as well as barley, a non-fixing species of N used as reference, were planted in agricultural soils in Zapopan, Jalisco, in the 2015-2016 autumn-winter season. During the growth of the species under study, destructive sampling was carried out at 93, 108 and 122 days after sowing (Das). In each sample the number of nodules per plant, dry matter content (Dm) and % N were quantified. With these values, the proportion of N derived from the atmosphere (% Ndfa) and amount of N fixed (kg ha-1) were estimated using the total N difference method.Key results: At 93, 108 and 122 Das L. exaltatus fixed 87.4, 86.9 and 187 kg of N ha-1; these values were equivalent to 71.0, 70.9 and 83.8% of Ndfa, respectively. The species L. rotundiflorus and L. mexicanus only showed significant values of N fixed until 122 Das.Conclusions: Under the conditions of this study it can be concluded that L. exaltatus was the most efficient species in the fixation of atmospheric N, due to a favorable symbiosis between the roots and the soil-fixing native bacteria of atmospheric N. |

Antecedentes y Objetivos: La fijación biológica del nitrógeno (FBN) en leguminosas nativas de México ha sido poco estudiada; particularmente en especies del género Lupinus no se tiene información al respecto. En este sentido, el objetivo de esta investigación fue cuantificar la acumulación de biomasa y nitrógeno (N) en tres lupinos silvestres del estado de Jalisco, México (Lupinus exaltatus, L. rotundiflorus y L. mexicanus), así como evaluar la FBN en términos de cantidad de N fijado (kg ha-1) y proporción de N derivado de la atmósfera (% Ndda).Métodos: Las especies en estudio al igual que la cebada, una especie conocida como no fijadora de N y usada de referencia, fueron cultivadas en suelos agrícolas de Zapopan, Jalisco, en el periodo otoño-invierno de 2015-2016. Durante el crecimiento de las especies en estudio se realizaron muestreos destructivos a los 93, 108 y 122 días después de la siembra (Dds). En cada muestreo se cuantificó el número de nódulos por planta, contenido de materia seca (Ms) y % de N. Con estos valores se estimó mediante el método de la diferencia de N, la proporción de N derivado de la atmósfera (% Ndda) y cantidad de N fijado (kg ha-1).Resultados clave: A los 93, 108 y 122 Dds, L. exaltatus fijó 87.4, 86.9 y 187 kg de N ha-1, lo cual fue equivalente a 71.0, 70.9 y 83.8% de Ndda, respectivamente. Las especies L. rotundiflorus y L. mexicanus solamente mostraron valores significativos de N fijado hasta los 122 Dds.Conclusiones: Bajo las condiciones de este estudio se puede concluir que L. exaltatus se caracterizó por ser la especie más eficiente en la fijación de N atmosférico, debido a una favorable simbiosis entre las raíces y las bacterias nativas del suelo fijadoras de N atmosférico.
