Supplementing Pine-Wiregrass Range With Improved Pasture In South GeorgiaNative forage on pine-wiregrass ranges is low in quality and poor in palatability most of the year. Management techniques to overcome these problems and to utilize this resource are needed. Acceptable beef production can be achieved with proper combination of burned-unburned range during spring and summer when accompanied by adequate feed during fall and winter. Combining use of improved pasture at the rate of 0.6 acre per cow with native range during the spring-summer grazing period or during only the summer boosts calf weights and maintains cow weights from year to year over weights of cattle grazing range-only during spring and summer./El forraje que proporcionan los pastizales nativos en bosques de pino es bajo de calidad y palatabilidad durante la mayor parte del año. La producción de bovino de carne es aceptable con una combinación de pastos quemados y sin quemar durante la primavera y el verano si los animales son suplementados durante el otoño y el invierno. Sin embargo, si se pastorea pastizal nativo y 0.6 acres por vaca diario dallisgrass (Paspalum dilatatum) y zacate Bahía (P. notatum) durante la época de pastoreo de primavera, verano o un verano solamente, si aumenta el peso de las vacas y el de los becerros al destete.
Some Soil Age-Range Vegetation RelationshipsSoil texture and development determine the kinds of range plants that grow in west central South Dakota. Bluestems, sideoats grama, and prairie sandreed are important species on very weakly developed soils but are less important on more strongly developed soils than cool-season mid- and tall-grasses. Western wheatgrass, green needlegrass, and buffalograss are important on well developed soils except those that are very coarse textured where needleandthread is important. Soil structure and fertility changes probably are the important factors affecting vegetation as a soil develops.
Phenology and Control of Common Broomweed on Texas RangelandsCommon broomweed (Gutierrezia dracunculoides (DC.) Blake) were effectively controlled with 2,4-D at 0.125, 0.25 or 0.5 lb./acre applied during stem elongation around May 15. The same rates of 2,4-D were less effective when applied in early April prior to complete emergence of the common broomweed seedlings or in mid-June after initiation of floral branches. Picloram combined with 2,4-D at 0.063, 0.125 or 0.25 lb./acre of each herbicide controlled 94 to 100% of the common broomweed population regardless of application date. Dicamba was more effective when applied in early spring than were equal rates of 2,4-D. Control of common broomweed from applications of picloram or dicamba in early April was attributed to residual herbicide activity on seedlings germinated subsequent to treatment. However, no treatment prevented germination and establishment of common broomweed in the fall following application of herbicides in the spring.
