Use Of Capacitance Sensors For Development Of Conservative Irrigation Regimes, Ethan Daniel Hagen
Use Of Capacitance Sensors For Development Of Conservative Irrigation Regimes, Ethan Daniel Hagen
Masters Theses
Several experiments were conducted to further develop capacitance sensor-based automated irrigation systems. The first experiment tested whether the photosynthetic response to decreasing volumetric water content (VWC) differed among four species tested. A sigmoidal curve best described the relationship for all species (r2 [r-squared]>0.86). The VWC that maintained maximum photosynthesis at 90% was selected as a potential conservative irrigation set point and values were not different between species, nor were 100% container capacity values. This indicates that a single set point is adequate to initiate irrigation and that a common upper threshold for VWC can be used for this …
Heirloom Seeds Of Tennessee: Seeds And Their Stories, Fiona Evelyn Mcanally
Heirloom Seeds Of Tennessee: Seeds And Their Stories, Fiona Evelyn Mcanally
Masters Theses
Heirloom seeds continue to be grown in home gardens of Tennessee, an area of high agrobiodiversity, but are rapidly declining in local communities. Individual seed savers in communities have been replaced by formal networks that include seed swaps and national and regional seed saving organizations. Seed saving organizations grew out of an increased interest in heirloom vegetable production over the last forty years as a result of the expanding local food movement and concerns of loss of biodiversity. This study uses a multidisciplinary approach in plant and social sciences to document seed saving, the motivation of seed savers, and the …

The Influence Of Organically Managed High Tunnel And Open Field Production Systems On Strawberry (Fragaria X Ananassa) Quality And Yield, Tomato (Solanum Lycopersicum) Yield, And Evaluation Of Plastic Mulch Alternatives, Jeffrey Thomas Martin
Masters Theses
High tunnels extend the production season, and increase fruit quality, yield and crop marketability of high-value crops, but have been underutilized in the Southeast. In this study, organically managed variety trials of two high-value crops, strawberry (Fragaria x ananassa) and tomato (Solanum lycopersicum), were conducted in high tunnel (HT) and open field (OF) production systems to compare yield and quality. Furthermore, specialty crops are commonly grown on black plastic mulch to increase earliness of harvest, fruit quality and yield. However, plastic disposal is time consuming and costly. Degradable mulches reduce removal costs, lessen environmental impacts, and …
Alternative Poa Species As Permanent And Temporary Turfgrasses In The Transition Zone, Samuel Lucas Freshour
Alternative Poa Species As Permanent And Temporary Turfgrasses In The Transition Zone, Samuel Lucas Freshour
Masters Theses
As restrictions on water, fertilizer, and pesticide use increase, along with public pressure, turfgrass practitioners will need ways to meet the challenges of reduced inputs while still maintaining acceptable turf quality. Proper selection of turfgrass species and cultivars that are adapted to the climate, intended use, and level of expectation is the best and first line of defense for reduced input situations. The objective of this study was to evaluate alternative species from the bluegrass (Poa) genus for their performance as both permanent and temporary winter turfgrass species. In 2010 and 2011, 45 different treatments consisting of 37 different bluegrasses …
