Strategies to improve C4 photosynthesis, water and resource-use efficiency under different atmospheres, temperatures, and light environments
… are productive, resilient, and require minimal use of inputs. Plants using C4 photosynthesis display many of these traits: in C4 leaves, a biochemical carbon-concentrating mechanism significantly boosts photosynthetic efficiency and overall productivity, while improving the efficiency with which …

Cropping systems under water-limited conditions: effects of rotation and nitrogen management on yield, resource use efficiency, profitability, and soil properties
… requires cropping systems that balance yield, resource-use efficiency, and economic viability. This thesis integrates results from field studies conducted at different temporal scales, location and under different water-management conditions to evaluate how crop rotation diversity, cover crop …

Quantifying genotypic and environmental factors affecting potato canopy growth
… simpler, more descriptive model was selected for use in further canopy quantification. The effects of planting date, nitrogen rate, cultivar and stem density were examined in two multi-year experiments. Planting date had a strong effect on early growth, though subsequent growth was less sensitive …

SURVIVAL IN THE FOREST UNDERSTORY: RESILIENCE AND RESISTANCE TO DAMAGE IN NATIVE AND INVASIVE WOODY PLANTS
… species exhibit greater productivity and resource use efficiency, but the extent to which plants are subject to tradeoffs between productivity and survival is unknown. Herbivory and freezing events are common sources of damage in the forest understory, and non-structural carbohydrates …

Elucidating the ecophysiological complexities of maize and soybean intercrop systems to improve ecosystem services
… of increased production per unit area, efficient resource-use, and enhanced yield stability in plant mixtures relative to monocultures, particularly by cereal-legume intercrops. The mechanisms behind such advantages have been attributed to the relaxation of competition due to niche …

Dynamic Environmental Control of a Vertical Farm for Lettuce Production
… consumed by lighting systems as well as overall resource use. Previous efforts in dynamic controls in vertical farming have built on an abundance of literature on yields, resource use efficiencies, crop indices, anthocyanin content, and tipburn mitigation reported under a variety of fixed light …

The effect of soil nutrient availability on resource allocation in tropical tree species
… and in their functional strategies for resource use and acquisition. Soil resources influence productivity of tropical forests and the distributions of tree species across edaphically heterogeneous landscapes. My dissertation evaluates functional variation among tropical trees in …

Functional traits and resource-use strategies of native and invasive plants in Eastern North American forests
… species invasive to this region have superior resource-use strategies, or alternatively, they share the same metabolic tradeoffs as the native flora. First, at a global scale, I addressed the largely untested hypothesis that biogeography places significant constraints on trait evolution. …

Energy Models for Urban-Integrated Agriculture
… (UIA) is a promising solution to increase urban resource use efficiency, improve local food supply and population well-being. In particular, Controlled Environment Agriculture (CEA) offers the potential to compete with traditional agriculture through its large annual yields on small footprints. …

Quantitative multifactor analysis of planter settings and row unit design for corn stand establishment in precision agriculture
… for maximizing yield potential and enhancing resource use efficiency. Despite considerable advancements in planting technologies, challenges associated with variability in seed placement accuracy, seed depth, and overall population uniformity persist. This variability is attributed to …

The potential role of Vertical Plant Farms in contributing to the environmental sustainability and security of the global food system
… the context of environmental sustainability and resource use efficiency in recent years. VPFs have been demonstrated to utilise significantly less land, fertiliser, water and pesticides than conventional counterparts. Furthermore, VPFs’ climate-independent nature has the potential to increase …
