The Factors Influencing The Leader’S Perceptions Of Success Of Dairy Cooperatives: The Case Of Cumbal Nariño’S Dairy Associations, Omar Efren Aza Fuelantala
The Factors Influencing The Leader’S Perceptions Of Success Of Dairy Cooperatives: The Case Of Cumbal Nariño’S Dairy Associations, Omar Efren Aza Fuelantala
Masters Theses
During the last few decades, Colombia’s dairy sector has been affected by economic, social, and political conditions, not only endangering it but also putting at risk the long-term sustainability of the dairy industry. To mitigate these conditions, the dairy farmers have joined cooperatives, which enabled them to gain some strategic advantages and reduce the adverse effects of the economic, political, and social conditions. This study evaluates the influence of economic, financial, membership, management and operational characteristics on the presidents’ perceptions of success of the dairy associations in Cumbal-Nariño. To accomplish this objective, we surveyed the presidents of dairy associations in …
Pollinator Community Homogenization And Pollination Services In Agroecosystems, Devon S. Eldridge .
Pollinator Community Homogenization And Pollination Services In Agroecosystems, Devon S. Eldridge .
Masters Theses
Pollination, or the transfer of pollen to plant stigmas, is an essential part of plant reproduction. The term “pollination system” refers to the floral phenotype and pollinator of a given plant. Although angiosperms exhibit a variety of different pollination systems, most rely partially or completely on animals, particularly insects, to vector their pollen. In agricultural systems, understanding the pollination system of the crop species is necessary to produce an economically valuable yield. Moreover, agricultural management may affect pollination systems by altering the abundance, diversity, or function of the pollinator community. In natural ecosystems, there is a great diversity of pollinating …
Risk Management Potential Of Supplemental Irrigation For Cotton In A Sub-Humid Climate Under Climate Change, Wen Liu
Masters Theses
Adoption of supplemental irrigation to reduce cotton yield losses is a potential risk management strategy for farmers given increasingly frequent drought periods due to climate change. However, cotton farmers in the rolling landscape areas of the lower Mississippi River Basin (MRB) are concerned about whether an investment in supplemental irrigation is economically feasible. This study determined the impacts of the effects of risk exposure on optimal irrigation strategies for cotton production under climate change in West Tennessee. A crop simulation model was calibrated and validated using measured data from cotton irrigation experiments at Jackson, TN over three years (2006–2008). Simulated …
Financial Feasibility And Factors That Lead To Profitability For Small-Scale Farmers In Rwanda., Saheed Adeniyi Orimadegun
Financial Feasibility And Factors That Lead To Profitability For Small-Scale Farmers In Rwanda., Saheed Adeniyi Orimadegun
Masters Theses
This study will analyze small-scale poultry farming in the Musanze district of Rwanda. Poultry farming offers a source of protein and economic subsistence for households in this region but studies suggest that the smallholder farmers need training for effective production of broiler for these purposes. To this end, a project - Feed the Future Tworore Inkoko, Twunguke (TI) - funded by the United States Agency for International Development (USAID) and the African Sustainable Agriculture Project (ASAP) Foundation, and led by the University of Tennessee Institute of Agriculture (UTIA) and Zamura Feeds Ltd., was initiated to help the smallholder broiler farmers …
Supplementing East Tennessee Landscapes For Pollinators With Native Perennials, Amani Khalil
Supplementing East Tennessee Landscapes For Pollinators With Native Perennials, Amani Khalil
Masters Theses
Tennessee, home to the Great Smoky Mountains, is a biodiversity hotspot for many plant and animal species, yet it receives relatively few conservation dollars (Jenkins et al., 2015). As a biodiversity hotspot, this region may be home to many endemic species, but little is known about the abundance or diversity of insect pollinators. In order to both estimate pollinator communities in East Tennessee and pollinator forage preferences for native Tennessee plants, we established four plots, comprised of three plant families across five common land use types. Over two field seasons we collected nearly 7,300 insect specimens with a total sampling …
Identifying Drought Tolerance Traits In Tennessee Soybean Genotypes: Recovery From Severe Water Deficit Stress, Samuel W. Purdom
Identifying Drought Tolerance Traits In Tennessee Soybean Genotypes: Recovery From Severe Water Deficit Stress, Samuel W. Purdom
Masters Theses
Ninety-four percent of U.S. grown soybeans are produced under rainfed conditions with intermittent droughts occurring late in the season during reproductive growth stages. Due to the temporary nature of drought, the ability of a crop to survive and recover effectively from water deficit stress is important for ensuring yield stability. In 2019 and 2020, two greenhouse experiments and two field studies were conducted to screen eleven soybean genotypes for transpiration response and recovery from water deficit stress and high vapor pressure deficit (VPD). In the first greenhouse study, soybean plants were grown in pots sealed to prevent evaporation and plants …
