Use of on-farm commercial fields and research stations provides the opportunity to evaluate cultivar performance across a wide range of environmental conditions and management situations. The Arkansas Rice Performance Trials (ARPT) utilize experiment stations and commercial fields throughout the rice-producing regions of Arkansas to evaluate the performance of commercial rice cultivars. These trials provide information on agronomic factors of cultivars such as disease resistance, lodging, plant stand, plant height, grain yield, and milling yield across a range of environmental conditions, growing practices, and soil types. Choosing a cultivar is a critical decision annually for producers. Studies in 2022 were in grower fields in Clay, Desha, Greene, Jackson, Lawrence, and Lonoke counties, and on research stations in Arkansas, Mississippi, Poinsett, and St. Francis counties. The average grain yield across all 10 trials was 176 bu./ac with the highest average yielding location being Arkansas County at 191 bu./ac. Cultivars that had the highest average grain yield across all locations include RT XP780, RT 7521 FP, RT 7401, RT XP753, RT 7302, RT 7331 MA, Ozark, and DG263L. The average milling yield across all cultivars was 56/70 (%HR/%TR), with Addi Jo, Jupiter, Leland, DGL2065, and CLM04 producing the highest average milling yields. [ABSTRACT FROM AUTHOR] |
