    Small-grain cultivar performance tests are conducted each year in Arkansas by the Arkansas Agricultural Experiment Station, Department of Crop, Soil and Environmental Sciences. The tests provide information to companies developing cultivars and/or marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for smallgrain producers

    Further Tests of Band Placement of Insecticides for Clover Root Borer Control

    Weaver & Haynes (1955) described a method of placement of insecticides in bands under red clover seed that achieved control of the clover root borer, Hylastinus obscurus (Marsh.). Band placement was as effective at 0.75 pound of toxicant per acre as broadcast treatments at 1 pound or more as reported by Gyrisco et al. (1954) and App & Everly (1950). Since the 1951–53 tests were carried out in one location on small plots and applied by a farm crew experienced in experimental procedures, it was desired to test the band placement method more extensively. Tests in 1954–56 were conducted at seven different locations, using different band seeding equipment operated by farmers as well as technically trained personnel. The results of these trials are reported in this paper

    Effects of early‑life experience on innovation and problem‑solving in captive coyotes

    Early-life experience often shapes behaviors like innovation and exploration. These behaviors are important to animals encountering novel food resources in diverse habitats, such as mesocarnivores in urban areas. To understand if early-life experiences impact later-life behavior, we examined how coyotes (Canis latrans) responded to a multi-access puzzle box at two life stages: pup (~ 7 weeks) and dispersal (~ 10 months). We first exposed pups, still living with their parents and littermates, to a baited puzzle box. At dispersal age, we again tested both these pups and an age-matched control group that was not exposed to the puzzle box as pups, both as individuals and with their pair-mate. We quantified problem-solving capability, latency to approach, and time spent in proximity to the puzzle box. Most pup litters solved two of the three access points, but no dispersal-age coyotes solved any access point. The amount of time dispersal-age coyotes spent near the box during pair-testing increased with (1) more time spent near the box during single-testing, (2) more time their pair-mate spent near the box during pair-testing, and (3) if their pair-mate came from a litter that previously solved the box. These results suggest that early-life experience and social interactions influence exploratory behavior at dispersal age, but coyotes exhibit increased avoidance behavior at this life stage, which corresponds with the life stage that overall survivorship decreases. Our study provides insight into how early-life experiences shape adult behavior in mesocarnivores
