Bermudagrass or Bahiagrass

Forage systems are essential for the livestock industry, and the selection of the right grass species is crucial for optimal animal performance. Bermudagrass and bahiagrass are introduced summer perennial grasses that are well adapted to Central and East Texas. Hybrid bermudagrass is a highly productive, warm season grass that grows well in areas with mild winters and long, hot summers. It has a fine stem and leaf structure, making it a highly palatable forage option for livestock. Hybrid bermudagrass is known for it’s high yield potential and nutrient… Read More →

Bearing with Sandburs-Managing a Painful Pest

February is the time for forage managers to begin waging war against this pest. Many Cenchrus spp. go by grassburs, sandburs, stickerburs, or other names. This genus includes annual and perennial grasses that produce a pain-inflicting seed head. The burs that house the seed not only have spines but have fishhook-like barbs that grip what they have grabbed (Fig. 1).  There are three native species of sandburs in Texas that make up most infestations. These are also referred to as grassbur by many:  field sandbur – Cenchrus spinifex … Read More →

Importance of Potassium

Potassium is an essential element in plants and is considered one of the three macronutrients, along with nitrogen and phosphorus. The amount of K is reported in almost all routine soil samples. Unfortunately, at times potassium can go from being the least expensive to the most expensive of the three macronutrients. Ignoring the importance of potassium fertilization and not maintaining adequate soil levels can lead to forage losses and ultimate stand decline. Potassium is essential for producing economical yields and maintaining persistence in our forages. The role of… Read More →

Should you burn your bermudagrass hayfield?

There are often many questions surrounding the practice of burning pastures and hayfields. Let’s look at the more frequently asked questions.   Is it a good idea to burn my hayfield? There are several benefits to burning your hayfield. Burning can help producers manage thatch in their stands. If the thatch layer becomes too thick over time, several issues can occur. For example, thatch can tie up nutrients and serve as a “spore reservoir” for leaf spot diseases. Thick thatch layers can also hinder or delay green up,… Read More →

Renovation

During the dormant season we often get anxious for warm weather and green pastures so we start thinking about renovation. Renovation is a practice or series of management practices which “restores the vigor” or “makes new again.” In pasture management, renovation refers to improvement of a permanent pasture by changed management. Renovation of bermudagrass pastures may be as simple as soil testing and applying proper fertilization; or, it may be as complex and intensive as destroying the existing sod, preparing a seedbed and sprigging again.   Some renovation… Read More →

Does a New Year Mean a New Pasture/Hay Meadow?

It’s always best to initiate the planning process the year prior to actual planting. Evaluate the farm’s forage needs. Consider how the forage will be used (grazing vs. hay), what species are better adapted to your area (season, soil type, rainfall) and what resources (equipment, money, and time) are available. Reestablishment should be considered when less than 40% of the desirable species exist. For exclusive hay production: Take visual appraisal of meadow. Bald spots may fill in with time, fertilization and weed control. Or bald spots may be… Read More →

Native Grasses for Texas

One may be surprised to learn that bermudagrass and bahiagrass are NOT native to Texas much less to the United States. There are numerous species of grasses and forbs that can be utilized for forage throughout the state of Texas. Keep in mind as we select forages we need to be mindful of our production system goals, location (soil type and rainfall), and the nutrient needs of our livestock (and/or wildlife). Many livestock producers are considering forage species and varieties that do not require as much fertilizer as… Read More →

Impact of Sub Freezing Temperatures on Warm-Season Perennial Grasses

Warm-season perennial grasses are the basis of pasture systems and livestock production in Texas. The most prominent warm season species are bermudagrass (seeded and hybrid) and bahiagrass. Neither of these species is native to the state of Texas but they are well adapted to Central and East Texas. Unfortunately they can be greatly impacted by cold winter temperatures. Central and East Texas have seen record temperatures in late December. Many may be concerned about whether or not their warm season forages have survived these weather conditions.   Bermudagrass… Read More →

Common Winter Weeds in Pastures and Hay Meadows

Buttercup (Ranunculus spp) Spray buttercup in late February or early March before it flowers. This weed is easily controlled with 2,4-D amine, Metsulfuron 60 DF, Cimarron Plus, Grazon P+D, GrazonNext HL and dicamba + 2,4-D (Weedmaster). In dormant bermudagrass/bahiagrass glyphosate (Roundup) will control buttercup at normal use rates.   Groundsel (Senecio spp) Metsulfuron 60DF or Cimarron Plus has proved to be the most effective herbicide for groundsel control. Apply in the rosette stage (~March). Grazon P+D provides partial control.   Red Sorrel (Rumex acetosella)   Grazon P+D provides… Read More →
