Preventative Weed Management Strategies In Arkansas Tomato Production, Gracie E. Morrison, Matthew Bertucci

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Cost-effective weed suppression is an important consideration for tomato growers. Growers often choose methods which minimize hand labor, as hand weeding can be prohibitively expensive. This project determined economic viability of high tunnel tomatoes treated with several methods of weed control, both organic and chemical. These methods included: 2-week hand weeding, 1-week hand weeding, preemergent herbicide application (plots sprayed with herbicide prior to weed emergence), straw mulch (plots bedded with straw), landscape fabric (plots covered in fabric), and untreated weedy control plots. These six treatments were applied to randomized blocks in a high tunnel. Weeding, planting, and harvesting were all …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The skin color of muscadine grapes (Vitis rotundifolia) is typically classified as black or bronze. A glutathione S-transferase, VrunGST4, has been identified as a candidate gene for berry skin color in muscadine grapes. A molecular marker was developed within VrunGST4 to distinguish between muscadine genotypes (cultivars and selections) with bronze (T:T), heterozygote black (C:T), and homozygote black (C:C) berries. The objectives of this study were to determine whether there was a correlation between berry skin color and total anthocyanin content and to calculate additive and dominance effects of VrunGST4 in determining total anthocyanins in the berries of two biparental F1 …


The Economics Of On-Farm Rice Drying In Arkansas, Clayton J. Parker, Lanier Nalley Jan 2020

The Economics Of On-Farm Rice Drying In Arkansas, Clayton J. Parker, Lanier Nalley

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Globally, rice producers are faced with the temporal problem of deciding the optimal time to harvest rice. When harvested, paddy rice is typically at a harvest moisture content (HMC) between 15% and 22% and subsequently dried by the mill to a moisture content (MC) of 12.5%. Riceland Foods Inc., the largest miller of rice in the world, uses a stair-step pricing model to charge farmers to dry, which can complicate the timing of harvest as producers try to balance the tradeoff of minimizing drying costs by waiting to harvest at lower HMC vs. maintaining higher rice quality typically observed when …


The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin Jan 2020

The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sulfur dioxide is an inorganic compound (IC) and air pollutant that causes health risks in humans. The buildup of sulfur dioxide (SO2) in enclosed indoor spaces is, therefore, a concern to human health, especially since the average person spends 90% of his/her time indoors. This study focused on decreasing SO2 concentration in a cost-effective and simple way—by using botanical biofiltration, or the uptake of pollutants by plants. Research in biofiltration has focused mostly on the remediation of volatile organic compounds (VOC). However, research has also shown that plant species that remediate VOC efficiently also have the potential for efficient IC …

Trends In Nectar Production And Concentration Of Hummingbird-Pollinated Flowers: An Investigation Of Three Flowers Of The Ecuadorian Cloud Forest: Palicourea Demissa, Mezobromelia Capituligera, And Kohleria Affinis, Grace Palmer

Independent Study Project (ISP) Collection

Nectar concentration and sugar production both impact and are impacted by pollinator activity through a complex system of coevolution. Additionally, a variety of morphological and environmental factors influence the nectar properties of animal-pollinated flowering plants. Nectar concentration and nectar production rate (NPR) of three hummingbird-pollinated plants, Palicourea demissa, Mezobromelia capituligera, and Kohleria affinis, were measured. These flowers occur and were studied in the southern section of the Chocó-Andean subtropical montane rainforest, in the Pichincha province of Ecuador. Flowers were bagged for 24 hours and sampled at approximate two-hour time intervals for 12 or 24 hours. Nectar concentration and sugar production …
