A greenhouse experiment has shown that total nitrogenase activity of alfalfa (Medicago sativa L.) is not significantly affected when grown in association with timothy (Phleum pratense L.), smooth bromegrass (Bromus inermis Leyss) or orchardgrass (Dactylis glomerata L.) except after initial harvest when decreased alfalfa activity was associated with smooth bromegrass or orchardgrass. It was concluded that mixed cultures of alfalfa with timothy, smooth bromegrass or orchardgrass have no effect on alfalfa N2 fixation. The results also suggest the occurrence of N transference from alfalfa to associated grasses. It is speculated that this transfer is not primarily due to the death of roots and nodule tissue (after harvest), but involves some degree of N excretion during the period before initial harvest.Key words: Alfalfa-grass mixtures, N2-fixation, nodule activity, N-transference

Effect Of Feeding

Alfalfa or orchardgrass hay was fed to cattle before feeding fresh alfalfa herbage at the vegetative to early bud stage of growth to observe the subsequent impact on bloat. Alfalfa hay supplements reduced the incidence of bloat by a third in one trial, but no effect was seen in a second trial. In contrast, supplements of orchardgrass hay reduced the occurrence of bloat by > 90% in 2 yr of trials. Supplemental orchardgrass hay can be effective in the control of pasture bloat.

Bowley, S. R. and Hancock, D. 2011. DIVIDEND VL orchardgrass. Can. J. Plant Sci. 91: 793–795. DIVIDEND VL is a late-maturing orchardgrass (Dactylis glomerata L.) cultivar for silage and hay production in mixtures with alfalfa (Medicago sativa L.) in eastern Canada. The population was developed at the University of Guelph, Guelph, ON. DIVIDEND VL matured at a slower rate when grown in pure stand and in binary mixtures with alfalfa compared with the cultivars OKAY and Rapido. When harvested at the same date, DIVIDEND VL averaged 7% lower in biomass yield compared with OKAY, but the herbage was less advanced in its maturity.

Con la finalidad de determinar durante un año el comportamiento del rendimiento de forraje en una pradera de alfalfa-ovillo (Medicago sativa L. – Dactylis glomerata L.) al variar la frecuencia e intensidad de pastoreo, se evaluaron seis tratamientos resultantes de la combinación factorial de dos frecuencias (alta y baja) y tres intensidades de pastoreo (ligera, media y severa, con alturas de forraje residual de 3 a 6, 7 a 10 y 11 a 14 cm, respectivamente), en un diseño de bloques al azar con cuatro repeticiones. La unidad experimental fue una parcela de 100 m2. Para el pastoreo se emplearon borregos ‘Columbia’, sin ser sujetos de medición alguna. La interacción de los factores no mostró efecto en variable alguna. El rendimiento anual de forraje fue mayor (4 %) con alta frecuencia de pastoreo y el pastoreo severo (3 a 6 cm) generó 19 % más rendimiento anual de forraje. Los pastoreos frecuentes y severos favorecieron un mayor rendimiento de forraje de la pradera alfalfaovillo, pero también permitieron la invasión por malezas lo que puede reducir la persistencia de la pradera. El patrón de respuesta de la alfalfa en producción de forraje a los cambios en la intensidad de pastoreo fue diferente al del ovillo.

Steers were grazed on pastures with alfalfa and orchardgrass grown in monoculture strips with alfalfa covering 100, 75 or 50% of the ground area. The forages were maintained at an early stage of growth during the trial. The incidence of frothy bloat in cattle was reduced by 70 to 90% when grass was a component of the pasture. Given unconstrained free choice, the legume was preferred over the grass by steers. Key words: Steers, frothy bloat, Medicago sativa L., Dactylis glomerata L., mixed pastures, grazing

Alfalfa herbage at the vegetative to early-bud stage of growth was simultaneously fed to cattle with alfalfa- grass mixtures containing 25, 40 or 50% orchardgrass. At all three levels of orchardgrass, there was either complete prevention of bloat or it was substantially reduced. Alfalfa alone yielded 334 cases of bloat as compared to 25 for the mixtures. During the warmest and driest intervals, bloat was reduced only by one-third when the feed alfalfa contained 25% orchardgrass.
