James Rogers, Ph.D., associate professor of forage systems, is testing how cover crops can be grown as summer forage.
In our region of the Southern Great Plains, we basically grow forage during the spring and fall, corresponding to our seasonal rainfall pattern. We are typically short on forage during the winter and...
Consider weather, variety, soil, seedbed preparation, equipment and seed quality.
Like producers, the Noble Research Institute has to prepare a budget for expenses including cereal pasture establishment.
Benefits of nativegrass mixtures on the Southern Great Plains have increased interest in effective methods of converting improved pastureland areas to nativegrass pastures.
Data and comments from Year 1 of a cow-calf study as part of Forage 365.
The Alliance for Grassland Renewal will host a novel tall fescue renovation school from 9 a.m. to 5 p.m., March 28, in Welch, Oklahoma.
The problem we encounter with fall and winter grazing of perennial forages is forage quality availability vs. forage availability.
Be flexible, proactive and have a mindset of year-long forage flow in addition to seasonal grazing.
In 2012, the Alliance for Grassland Renewal was formed, in part to make sure that producers are getting what they pay for when purchasing nontoxic-endophyte-infected tall fescue varieties.
Alfalfa stands within the Southern Great Plains are often infested with cotton root rot, causing heavily affected fields to be taken out of production within two to three years.
The bermudagrass stem maggot was first discovered in southern Georgia in 2010. This small fly is native to South Asia, and it is unknown how it invaded the United States.
If you use a dual-purpose wheat system of grazing and grain production, detection of the development of wheat's first hollow stem is critical to gauge when to remove cattle from grazing.
Tall fescue [Lolium arundinaceum (Schreb.) Darbysh = Festuca arundinacea] is an introduced, cool-season, perennial grass that is native from Europe to Siberia and into North Africa. The date of the...
Beef cattle can consume and obtain nutritional value from a variety of stockpiled forages to reduce the winter hay feeding period.
Numerous nontraditional fertilizers are being marketed with little replicated research demonstrating their effectiveness compared to traditional commercial sources of nitrogen, phosphorus and potassium.
Switchgrass (Panicum virgatum L.), is a native, warm-season (C4) perennial grass that can be found growing over the eastern two-thirds of the United States, Central America and southern Canada....
The Energy Independence and Security Act of 2007 set U.S. renewable fuel standards requiring the production of 16 billion gallons of ethanol from cellulosic biomass feedstocks by 2022. Switchgrass...
The majority of Oklahoma and Texas are currently in severe to extreme drought with northern Oklahoma and the Panhandle in exceptional drought. Things will get better; until then, producers will need to do an above average job of forage management.
According to the United States Department of Agriculture, the price of nitrogen fertilizer increased more than 120 percent between 2000 and 2007. More alarming are the unexpected periods when the price of nitrogen spikes well above the trend price.
So far 2012 has been a better year climate-wise than 2011. However, the full impact of the 2011 drought on warm-season forages was not fully realized until the early spring and summer of 2012.
Updated February 2018*While the years and numbers mentioned in this publication may be outdated, the strategies and principles listed are still accurate.* Drought can be defined simply as 75 percent...
The goal of many graziers is to increase forage production and utilization. A key component of increasing utilization is the ability to accurately determine forage mass. While some seasoned practitioners have a keen ability to visually estimate forage mass, the rest of us need some objective help.
Many perennial forage plants were forced into summer dormancy for survival due to the severity of the drought. Dormant plants survived on energy reserves stored in plant crowns and roots when normally they would have generated energy through photosynthesis in green leaves.
The Noble Research Institute recently undertook a study that may shed some light on management strategies for dealing with toxic tall fescue during fall and winter.
When the rain falls, here are some tips and strategies that will help you capture and use as much of it as you can.
Springtime in pasture and range management is "go time." As I start thinking about spring, here are some of the planning thoughts filling my head.
One of the major forage research emphasis areas here at the Noble Research Institute is developing perennial cool-season grass grazing systems that will take the place of annual cool-season forage systems.
