Hoop houses (high tunnels) have long been used by agricultural producers to extend the growing season and to establish crops earlier as compared to crops grown in the field.
More and more, farmers and ranchers are planting pecan orchards, hoping to grow a brighter financial future. In support of the pecan growers, Charles Rohla, Ph.D., builds on more than 30 years of pecan research tradition at the Noble Research Institute, studying ways to maximize the wonder nut's production and developing more effective management strategies.
The new Center for Pecan and Specialty Agriculture adds opportunities for ag education and collaboration
Oklahoma State University and the Noble Research Institute build on a 70-year legacy of collaboration as they serve their home state and beyond.
Six national institutions have become the first multistate and multidisciplinary study to receive funding specifically to work on pecans.
The Noble Research Institute is building a backyard. Four, actually.

One of the first Americans to appreciate the flavor of pecans was George Washington, who planted the stately trees on the lawns of Mount Vernon in 1775. Yet true cultivation of the nuts wouldn't...
Noble's Manager of the Center for Pecans and Specialty Agriculture, Dr. Charles Rohla, brings us up to date on some of the pecan projects currently active at the Institute.
When Center for Pecan and Specialty Agriculture manager Charles Rohla asked me to help at this year's Oklahoma Pecan Growers Association Convention, I was elated to expand my knowledge on this specialty crop.
Noble Research Institute researchers are studying ways to combat the pecan scab disease that decimates pecan orchards every year.
Joe and Jeannie Dobson return to their roots to enjoy the family land after years of city life.
One of the most damaging diseases in pecans is pecan scab, caused by the fungus Fusicladium effusum. It infects actively growing tissue, such as stems, leaves and nut shucks, when temperatures are above 70 degrees Fahrenheit and relative humidity is above 90 percent.
Pecan trees exhibit a strong tendency to produce a heavy crop one year, followed by one or more years of little to no production. This may best be characterized as alternate bearing with irregular symmetry.
Drought conditions cause extreme stress on pecan trees. It is important for producers to understand the effects of drought and how pecan trees cope with the stress it brings.
It is hard to believe that summer is almost upon us. This has the potential to be a heavy pecan crop year, if the drought has not hurt things too badly. To ensure a good crop, many management decisions need to be considered over the next few months, including proper fertilization and insect and disease control.
For decades, scientists have used molecular markers for research and breeding purposes to increase yields and water and nutrient efficiencies as well as disease and insect resistance in agricultural crops. Recently, pecan scientists have looked at the development of new technologies used in this research and considered its use in pecan breeding and research.
The Federal Marketing Order was created to benefit the domestic and global pecan market.
To help people stay engaged in agriculture, the AgrAbility Project was created in 1991 as part of the 1990 Farm Bill. Currently, 24 states have AgrAbility Projects to assist agricultural producers with disabilities.
Fertilization is just one pecan management practice that helps maximize crop production and provides optimal tree maintenance. Proper fertilization encourages growth of shoots and leaves, which is essential for increasing crop load and decreasing tree stress.
Nutrient management is essential for a successful pecan orchard or grove. With the high cost of fertilizer and the labor required for application, it is critical to accurately account for the nutrient needs of the tree for successful pecan management.
Proper fertilization can decrease stress and improve the health and development of trees. Annual application of nitrogen and adequate levels of phosphorus have been shown to help reduce alternate bearing in pecan trees.
Mother Nature has blessed several landowners in Oklahoma and Texas with a potential income enterprise. Native pecans are found along the rivers, streams and creeks in both states. On average, 35 million pounds of native pecans are harvested from both states.
In 2015, I wrote about the proposed Federal Marketing Order (FMO) for pecans. On May 6, 2016, the U.S. Department of Agriculture announced that the order passed by an overwhelming majority of pecan...
Pecan is an important crop in the Southern Great Plains. Recent USDA crop statistics report 175,542 acres of pecans in Texas and 141,765 acres in Oklahoma, with the majority of the acreage consisting...
It is the intent of this publication to provide methodology that appraisers, tax preparers and other interested parties can use in determining the value of pecan trees.
Pecan nut casebearer (PNC) is found throughout our pecan growing region and can be economically devastating to pecan producers. There are two to four generations of PNC per year with a new generation...
Charles Rohla, Ph.D., shares information to help pecan growers choose the best cultivars to grow in Oklahoma and Texas.
History has shown that the pecan industry is resilient, but the tariff trouble is proving to be just one hurdle the U.S. pecan industry needs to overcome. Thanks to recent storms, pecan growers now have bigger problems.

Adequate pollinators within the pecan orchard are imperative for optimal production.
Installation of an irrigation system is one of the most important steps in establishing a new pecan orchard. Water is critical to produce healthy trees capable of optimal fruit production.
