El crecimiento inverno primaveral de gramíneas forrajeras es limitado por las temperaturas del período. Para el sudeste bonaerense se han identificado especies y
cultivares de gramíneas introducidas o nativas con alto potencial para crecer a las temperaturas que normalmente ocurren en los meses de invierno y principios de primavera. No obstante, la expresión de dicho potencial, se hallaría limitada por la baja disponibilidad de formas asimilables de nitrógeno en los suelos. En este trabajo se condensa información publicada en una serie de trabajos en los que se estudió el efecto de la fertilización nitrogenada sobre el crecimiento de forraje a fines de invierno y principios de primavera de pasturas de raigrás anual y avena, que son las especies anuales más sembradas en la región,y se las utiliza para atenuar las deficiencias en el crecimiento de forraje de pasturas cultivadas y pastizales naturales. |

The practice of inoculating forage legumes with rhizobia strains is widespread. It is assumed that the inoculated strain determines the performance of the symbiosis and nitrogen fixation rates. However, native-naturalized strains can be competitive, and actual nodule occupancy is often scarcely investigated. In consequence, failures in establishment, and low productivity attributed to poor performance of the inoculant may merely reflect the absence of the inoculated strain in the nodules. This study lays out a strategy followed for selecting a Rhizobium leguminosarum sv. trifolii strain for white clover (Trifolium repens) with competitive nodule occupancy. First, the competitiveness of native-naturalized rhizobia strains selected for their efficiency to fix N2 in clover and tagged with gusA was evaluated in controlled conditions with different soils. Second, three of these experimental strains with superior nodule occupancy plus the currently recommended commercial inoculant, an introduced strain, were tested in the field in 2 years and at two sites. Plant establishment, herbage productivity, fixation of atmospheric N2 (15N natural abundance), and nodule occupancy (ERIC-PCR genomic fingerprinting) were measured. In both years and sites, nodule occupancy of the nativenaturalized experimental strains was either higher or similar to that of the commercial inoculant in both primary and secondary roots. The difference was even greater in stolon roots nodules, where nodule occupancy of the native-naturalized experimental strains was at least five times greater. The amount of N fixed per unit plant mass was consistently higher with native-naturalized experimental strains, although the proportion of N derived from atmospheric fixation was similar for all strains. Plant establishment and herbage production, as well as clover contribution in oversown native grasslands, were either similar or higher in white clover inoculated with the native-naturalized experimental strains. These results support the use of our implemented strategy for developing a competitive inoculant from native-naturalized strains.
