    Evaluating Effects of Bradyrhizobium and Arbuscular Mycorrhizal Fungi Inoculation on Yield Components of Mung Bean (Vigna radiata (L.) Wilczek) and Nitrogen Fixation
    Mott, Joshua; Abaye, Azenegashe Ozzie; Reiter, Mark S.; Maguire, Rory O. (MDPI, 2022-09-30)
    Mung beans (Vigna radiata (L.) Wilczek) are only inoculated in some production systems, but there is a current lack of knowledge on the best inoculants to use for effective nitrogen fixation (nodulation) and plant yields. The objectives of the present study were to determine if the dual inoculation of Arbuscular Mycorrhizal Fungi (F) and Bradyrhizobium (R) provides greater (a) mung bean yield and quality (b) nitrogen fixation for mung bean and residual soil nitrogen for the following crop, and (c) determine if these effects are consistent across various environments. Field trials were conducted in Blacksburg, VA (sandy clay loam), and Eastern Shore, VA (sandy loam), over the summers of 2020 and 2021. There were 5 treatments replicated 5 times for each variety at each site; R, F, R + F, high nitrogen (N) (100 kg ha−1), and a control, for a total of 25 plots per site. Mung beans grown in Blacksburg in 2020 and 2021 averaged 53.8% more seeds per pod than mung beans grown at the Eastern Shore. Overall yield components (seeds per pod, pods per plant) are heavily influenced by soil type. Dual inoculation significantly increased grain yield (+33%) compared to a synthetic N fertilizer application, but did not significantly increase grain yield compared to the control (+22%). Dual inoculation may increase the grain yields of mung beans compared to synthetic fertilizer regime, but does not show evidence of improving N fixation.

    Experiential Learning in the Time of COVID Pandemic: Study in the USA-Southern California and Arizona
    Abaye, Azenegashe Ozzie; Reiter, Mark S.; Ashford-Kornburger, Dana; Ziegler, Peter; Badon, Thomas; Mason, John; Wilbur, Jessica; Haymaker, Joseph (2022-11-07)
    The COVID pandemic has had an impact on higher education, especially on experiential learning opportunities. Travel restrictions due to the COVID-19 pandemic resulted in the cancelation of several study-abroad programs. To provide the much-needed in-person experience, we created an experiential learning course titled “Study in the USA" structured to accommodate variable domestic destinations. The key driver of the course is experiential learning, hands-on and face-to-face experience with industries involved in food production. The purpose of this course is to provide students with new insights through comparison and contrasting regional production practices across the United States. Specific objectives of the course are: 1) Provide students with a baseline understanding of experiential learning so they can apply academic learning in work settings appropriate for their career plans, 2) Engage students in developing skills and competencies relating to producing food in the time of COVID-19, and climate change, and 3) Develop a deeper understanding of challenges faced by people who are engaged in all aspects of agricultural enterprises. Overall, the course provided far more than academics to help students recover from the pandemic, it provided a perfect platform for social interaction which was missing for several years due to the COVID pandemic.

    Study in the USA: Arkansas, California and Arizona
    Abaye, Azenegashe Ozzie; Reiter, Mark S. (2022-03-16)
    The COVID pandemic has had an impact on higher education, especially on experiential learning experiences. Due to the COVID pandemic, we canceled several study abroad programs. To provide the much-needed hands-on and face-to-face experience, we created an experiential learning course titled “Study in the USA" with variable destinations. The key driver of the course is experiential learning, hands-on and face-to-face experience with industries involved in food production. It is the purpose of this course to give insights into differences in production practices between the western states like Arizona and California and mid-Atlantic states like Virginia. Specific objectives of the course are: 1) Provide students with a baseline understanding of experiential learning so they can apply academic learning in work settings appropriate for their career plans, 2) Engage students in developing skills and competencies relating to producing food in the time of COVID- and climate change, and 3) Develop a deeper understanding of challenges faced by people who are engaged in all aspects of agricultural enterprises. While in California and Arizona, the course focused on water issues including water scarcity, availability and utilization of water, and most importantly, the politics of water. The course also explored labor issues specifically associated with vegetable production, indigenous farming, and way of life. Overall, the course provided far more than academics to help students recover from the pandemic, it provided a perfect platform for social interaction which was missing for several years due to the COVID pandemic.
