| Abstract/Contents: | "Mowing and fertilization are management practices that influence weed populations: proper fertilization and high mowing increase the competitive ability of the turf, thereby decreasing weed competition. Frequent mowing can also disrupt weed seed production by removing the inflorescence prior to seed maturation. Two field trials were conducted in West Lafayette, IN to determine the influence of: 1) mowing height and nitrogen (N) frequency on buckhorn plantain (Plantago lancelolata L.) persistence and 2) mowing frequency on buckhorn plantain seed production. The first experiment was initiated in May 2017. Treatments included three mowing heights (5.1, 6.7, and 10.2 cm) and four annual N fertilization rates (0, 81, 163, and 244 kg N ha-1 yr-1). After 2 yr, buckhorn plantain coverage was lower in plots receiving 163 or 244 kg N ha-1yr-1compared to unfertilized plots (P = 0.0046). Buckhorn plantain coverage was also reduced at the 5.1 cm mowing height compared to 10.2 cm (P = 0.0349). However, low mowing reduced turf quality and increased Digitaria spp. coverage. The second experiment, initiated in May 2018, evaluated five mowing intervals: twice per week, weekly, once every two weeks, monthly, and once every two months. Three individual buckhorn plantain plants per plot were marked. For each mowing event, the number of buckhorn plantain inflorescences with and without anthers were counted, collected, dried, and stored in a cooler for germination testing. For the 2018 growing season, mowing frequency did not influence the total number of buckhorn plantain inflorescences produced (P = 0.3643), but frequent mowing did reduce anther development (P = 0.0007). Mowing twice per week resulted in fewer inflorescences with anthers compared to mowing every month or two. Mowing on at least a monthly basis reduced seedhead yield compared to mowing every two months (P = 0.0004). Average yields ranged from 4.1 to 15.8 g seedhead per plant for the twice per week and monthly mowing treatments, respectively; whereas mowing every two months averaged 37.1 g seedhead per plant. This research identifies species-specific cultural practices for buckhorn plantain management, which can help to reduce the reliance on and use of herbicides." |
