WATCH NOW! Weed and disease control, new varieties, soil fertility, and more from Rice Field Day
Author: Arkansas Row Crops

By U of A System Division of Agriculture

Scientists with the University of Arkansas System Division of Agriculture present the latest in Arkansas rice research in video recordings from an online field day held in August.

The rice field day videos cover new varieties, the latest research in hybrid varieties, soil fertility, weed management, and disease and pest control. Bob Scott, former director of the Rice Research and Extension Center and new Division of Agriculture senior associate vice president and director of the Arkansas Cooperative Extension Service, welcomed field day participants and Roger Pohlner, chairman of the Arkansas Rice Research and Promotion Board, gave an update on the board’s activities.

Online presentations by Arkansas Agricultural Experiment Station researchers and Extension Service specialists included:

In this video, Jason Norsworthy discusses weed management strategies in Arkansas rice production. With stops at the Pine Tree Research Station and the Rice Research and Extension Center, he shows the effects of various herbicides against some of Arkansas’ most tough-to-manage weeds in rice.

Norsworthy is a Distinguished Professor of weed science in the department of crop, soil, and environmental sciences. He conducts weed management research, with an emphasis on innovative research that will lead to a reduction in herbicide reliance, expenditures, and usage, and improve weed management efficiency in crops in Arkansas.

Hybrid rice varieties have become very popular among southern rice growers, in large part because of their reliably high yields. In this video, Ehsan Shakiba will give an update on hybrid rice breeding efforts at the Rice Research and Extension Center and the potential for the Division of Agriculture’s first hybrid rice release.

Shakiba is an assistant professor of rice breeding and genetics at the Rice Research and Extension Center in Stuttgart. His research efforts focus on developing good quality, high-yielding hybrid rice cultivars adapted to Arkansas and the rice-growing regions in the southern U.S. Link:

Trent Roberts offers some recommendations for optimizing soil fertility in rice production. In this video, Roberts will discuss some strategies for optimizing potassium, nitrogen and zinc fertility for rice production.

Roberts is an associate professor of soil fertility and soil testing for the Arkansas Agricultural Experiment Station and an Arkansas Cooperative Extension Service specialist. He investigates crop response to soil nutrients like nitrogen and potassium and hopes to develop better management strategies for crop production.


In this video, Yeshi Wamishe discusses rice fungicide management. She walks us through fungicide application timing and the impact of application volume on the efficacy of fungicides.

Wamishe is an associate professor of plant pathology and extension rice pathologist working out of the Rice Research and Extension Center in Stuttgart. Wamishe’s research efforts focus on ways to manage common rice diseases through foliar fungicide applications and seed treatments. In addition, she develops disease ratings for new and commercial rice cultivars to aid in grower planting decisions.


Xueyan Sha will discuss the rice breeding program along with descriptions of the newest rice varieties released by the breeding program that will be available to growers in 2021.

Sha Is a professor and rice breeder at the Rice Research and Extension Center in Stuttgart. His breeding program focuses on medium-grain varieties, semi-dwarf long-grain varieties, and hybrids.
