Vásquez, Susana I. Cossoli, Marcela R. Romero, Amalia M. E. Burr clover acidification basaltic rock dust Trébol de carretilla acidificación polvo de roca basáltica The aim of this study was to evaluate the effect of the inoculation of three rhizobia isolation of the strain collection from the chair of Agricultural Microbiology-UNNE, with and without the addition of basalt, on the growth of Medicago polymorpha. The 3x2 factorial experimental design was employed, with 6 treatments and 5 replicates, in a greenhouse: T1: A52 without basalt; T2: A52 with basalt; T3: A194 without basalt; T4: A194 with basalt; T5: A140 without basalt; T6: A140 with basalt. The data colleted was analyzed using ANOVA, with Fisher’s test (p<0,05) to check  means. It was possible to observe that  T6 and T4 treatments were superior than T2 by 37 % and 22% respectively, for the variable number of leaves per plant. T4 presented the highest number of branches per plant followed by T6, differing from T2 by 53% and 42% respectively. These differences are possibly due to the ability of these microorganisms to promote plant growth through the solubilization mechanism of rock dust that generates greater availability of nutrients. A52 developed in the opposite way, obtaining better results than the variables mentioned in the treatment without basalt (T1). There were no statistically significant differences among treatments for the variables root volume, root and shoot dry weight and biomass production per plant. Nodules were observed in one plant of T6 only. The rest of the treatments did not present nodules, possibly due to the high specificity of M. polymorpha or the type of soil used in the trial. El objetivo del trabajo fue evaluar el efecto de la inoculación de tres aislamientos de rizobios del cepario de la cátedra de Microbiología-UNNE, con y sin el agregado de basalto, sobre el crecimiento de Medicago polymorpha. El ensayo tuvo un diseño factorial 3 x 2, con 6 tratamientos y 5 repeticiones, bajo invernáculo: T1: A52 sin basalto; T2: A52 con basalto; T3: A194 sin basalto; T4: A194 con basalto; T:5 A140 sin basalto; T6: A140 con basalto. Los datos tomados fueron analizados mediante ANOVA, con prueba de Fisher (p<0,05) para la comprobación de medias. Se pudo observar que los tratamientos T6 y T4 fueron superiores al T2 en un 37% y 22% respectivamente para la variable número de hojas por planta. El T4 presentó el mayor número de ramificaciones por planta seguido del T6, diferenciándose de T2 en un 53% y 42% respectivamente. Estas diferencias posiblemente se deban a la capacidad de estos microrganismos de promover el crecimiento vegetal mediante el mecanismo de solubilización del polvo de roca que genera mayor disponibilidad de nutrientes. El A52 se comportó de manera opuesta, obteniendo mejores resultados en las variables mencionadas en el tratamiento sin basalto (T1). No hubo diferencias estadísticamente significativas entre tratamientos para las variables volumen radical, peso seco de raíz, vástago y producción total por planta. Sólo se observaron nódulos en una planta del T6. El resto de los tratamientos no presentaron nódulos, lo que podría atribuirse a la alta especificidad de M. polymorpha o al tipo de suelo utilizado en el ensayo. Instituto Agrotécnico "Pedro M.
