On proper forage availability and stocking rate estimation. Fact Sheets PSS-2594 Plan Grazing Management Using the Oklahoman Grazing Stick and PSS-2871 Pasture and Stocking Rate: The Key to Successful Livestock Production contain information Focus on achieving optimum yields by keeping 2 to 3 inches stubble height However, heavy grazing decreases bermudagrass yield and increases weed pressure in Bermudagrass is well known to tolerate heavy grazing. Keep in mind that 2 to 3 inches stubble height is essential for good bermudagrass Proper stocking rate can be achieved by monitoring available bermudagrass forage. Regarding proper bermudagrass fertilization. See Fact Sheet PSS-2263 Fertilizing bermudagrass Hay and the Oklahoma Pasture Fertility Guide for more information Should be maintained in good levels for good root development and plant regrowth. They will also increase the pasture productivity and quality.Īs a rule of thumb, it is recommended applying 50 pounds of nitrogen from May to Octoberįor every one ton of bermudagrass forage production. These measures will not only make bermudagrass more competitive against sandbur, but Will assure enough energy reserves for fast and vigorous bermudagrass regrowth. Proper fertilization will provide all nutrients, while proper stocking rate Proper fertilization and stocking rate combined are the best sandbur control in bermudagrass For more information regarding hay inspection, seeįactsheet PSS-2588 Evaluating Hay Quality Based on Sight, Smell and Feel – Hay Judging. If purchasing hay, it is recommended that you inspect the hay and inquireĪbout sandbur prior to purchase. Avoid introducing hay to your pasture that was produced in fields infested The spiny burs can easilyĪttach to them and rapidly infest the next pasture. Were previously in other pastures infested with sandbur. Years, it is recommended to inspect and clear equipment, animals and clothes that Using certified seed or sprigs, which ensure strict limits on weeds. Chemical control products labeled for sandbur control in bermudagrass pasture andĭuring bermudagrass pasture establishment, sandbur infestation can be prevented by Infestation and in combination with cultural suppression techniques. The last resource is herbicide application that should be used in severe pasture Good management practicesĬonsistently used every year will continuously decrease sandbur and increase bermudagrass In this case, the second alternative is cultural suppression. However, some pastures are already infested. In this way, sandburĬan easily take over poorly managed bermudagrass pastures on dry sandy soils. Retains soil moisture until conditions are good for germination. Not only allows the seed to stay viable for years in the soil, but also absorbs and The bur is what makes sandbur a successful competitor against bermudagrass. For effective control, sandbur must be identified and managed early in the vegetative Which is a terminal spike 1 to 3 inches long containing 6 to 20 spiny hairy burs (Figureġ). The easiest way to identify sandbur is after flowering, by looking at its inflorescence The leaf sheath is loose from the stem, smooth, flattened Also, the leaf blades are smooth, twisted and rangeįrom 2 to 5 inches long. ligule, that appears to have been cut by scissors Which is the bond between the leaf blade and sheath. Rhizomes and stolons are not produced,īut sandbur can develop roots at the lower nodes of the stems forming a mat, and rarely,īehaves as a short-lived perennial (Gould, 1975).ĭuring vegetative stage, the best way to identify sandbur is looking at the leaf collar, Keeps the seeds viable for years in the soil. Produces seeds inside of a specialized floret known as a bur. Plant prefers full sun, and can reach 3 feet high. If soil moisture and temperatures are adequate when viable seeds are present. Reach 52 F and peaks at 75 F (Boydston, 1989). Seed germination starts when soil temperatures Simply be referred to the species complex as “sandbur.” Control mechanisms do not differ between species therefore, it will They must be removed or controlled to prevent reductions in forage yield and Of sandbur can invade bermudagrass pastures, including field sandbur ( Cenchrus spindex Cav.), longspine sandbur ( Cenchrus longispinis Hackel Fern.) and Southern sandbur ( Cenchrus echinatus L.). Sandbur is one of the mostĬhallenging weeds affecting this system due to loss of palatability. However, bermudagrass pastures can beĮasily infested by weeds if they are not properly managed. Tolerance and low pest and disease pressure. Producers is due to its high forage production potential, drought resistance, grazing Bermudagrass ( Cynodon dactylon L.) is one of the most common introduced warm-season forages in Oklahoma pasturesĪnd serves as the forage base for many livestock enterprises.
