Rice Row Spacing and Seeding Rate Decisions

Presented by: Dr. Jarrod T. Hardke
Rice Extension Agronomist, University of Arkansas

Producers are increasingly looking for cultural management options in rice that will optimize their production. One of the most notable areas of interest is in planting arrangement and seeding rate. The overall goal is to optimize grain yield and milling yield while reducing seed costs and equipment costs. Trials evaluating row spacing and seeding rate combinations for varieties and hybrids are ongoing. Results of these studies and their impacts on production will be discussed.

Managing Nitrogen in Furrow-Irrigated Rice Production

Presented by: Justin Chlapecka
Phd Graduate Research Assistant, University of Arkansas

Furrow-irrigated rice acreage continues to increase across the Mid-South and is estimated at over 200,000 acres in Arkansas alone. Nitrogen (N) fertilization has the potential to be much less efficient where a flood is not present. Studies were conducted in 2018, 2019, and 2020 in commercial fields on both clay and silt loam soils across Eastern Arkansas to determine the optimal N management regime for furrow-irrigated rice. Findings from the three-year study across 16 sites will be discussed –including grain yield, milling yield, and recommendations depending upon soil type.
