Researcher studies cover crop effects on winter pasture

Noble Research Institute researchers are studying how cover crops could be part of a year-round grazing system that provides economic and environmental benefits to farmers and ranchers.

New Opportunities

Advanced breeding methods and a novel endophyte combine to offer agricultural producers a new alternative for winter grazing.

Fields of Green

Researchers from across the Noble Research Institute join forces through the Forage 365 initiative with the goal of providing year-round livestock grazing and reducing ranchers' dependence on buying hay.

Digging Deep

One of the Noble Research Institute's new research clusters aims to better understand plant growth and development.

Happy Calving Season!

It's my favorite time of year. Brand new baby calves take their first steps into the world, and it's a beautiful thing. I still remember the first one I watched, and I've been hooked on it ever...

Grazing Research Projects at the Noble Research Institute

Dr. James Rogers talks about the two grazing studies that the Noble Research Institute is conducting at its Pasture Demonstration Farm.

Studying How Cover Crops, Tillage Affect the Life in Soil

Kelly Craven, Ph.D., an associate professor of microbial symbiology, discusses his work with agronomist James Rogers, Ph.D., to better understand the impacts of cover cropping and tillage practices on the microbial communities, and ultimately the health, of Oklahoma soils.

Clearing Up Some Tall Fescue Misconceptions

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.

Fall and Winter Management of Toxic Tall Fescue

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.

Cotton root rot inhibits alfalfa stand longevity

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.

Careful management aids drought survival

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.

Research shows economics of pasture conversion

Benefits of nativegrass mixtures on the Southern Great Plains have increased interest in effective methods of converting improved pastureland areas to nativegrass pastures.

Cow-calf research evaluates fall, winter forage systems

Data and comments from Year 1 of a cow-calf study as part of Forage 365.

Alliance provides seed quality control

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.

Alliance offers 1-day tall fescue renovation schools

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.

Common sense guides stockpiled forage management

Beef cattle can consume and obtain nutritional value from a variety of stockpiled forages to reduce the winter hay feeding period.

First hollow stem in wheat triggers grazing decision

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.

Manage Forage Before (and During) Drought

Are you flexible enough to manage for that unspeakable term ... drought?

Stocking Rate Following Drought

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.

Do high nitrogen prices justify feeding soybean hulls?

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.

Planning, management promotes year-round grazing

Be flexible, proactive and have a mindset of year-long forage flow in addition to seasonal grazing.

Bermudagrass stem maggot invades Southern states

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.

Forage Drought Recovery: Looking Back, Planning Ahead

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.

Studies examine nontraditional bermudagrass fertilizers

Numerous nontraditional fertilizers are being marketed with little replicated research demonstrating their effectiveness compared to traditional commercial sources of nitrogen, phosphorus and potassium.

Springtime Is Pasture and Range "Go Time"

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.

Proper management promotes fall, winter grazing

The problem we encounter with fall and winter grazing of perennial forages is forage quality availability vs. forage availability.

Noble Research Institute reports expected forage establishment costs

Like producers, the Noble Research Institute has to prepare a budget for expenses including cereal pasture establishment.

Preparation promotes successful winter pasture season

Consider weather, variety, soil, seedbed preparation, equipment and seed quality.

Using a Plate Meter to Measure Forage Productivity

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.

Use Moisture Management Strategies to Survive Drought

When the rain falls, here are some tips and strategies that will help you capture and use as much of it as you can.

Stockpiling defers a forage from grazing to allow it to accumulate forage mass for grazing during fall and winter.

Understanding Soils With the Help of Sensors

Noble researchers are using sensors to gain a better understanding of the effects of tillage and cover crops on soil moisture, temperature, erosion and organic carbon.
