Process-based crop models are popular scientific tools to study the impacts of environment, variety and management decisions on crop growth. Some cultivar parameters in crop models cannot be measured directly and need to be estimated. In this research, two Bayesian methods, namely the generalized likelihood uncertainty estimation (GLUE) and Differential Evolution Adaptive Metropolis (DREAM) algorithm, were used to estimate the parameters of the maize module of the Agricultural Productions Systems sIMulator (APSIM-Maize) for the first time. Six cultivar parameters of APSIM-Maize were estimated using GLUE and DREAM, respectively. Both the GLUE and DREAM methods were able to give accurate simulations …

Tillers are vegetative branches found in grasses, which develop in early stages of plant life. Located at the base of the central stalk, tillers have agronomical importance by increasing seed production with fewer tillers, or providing alternative forms of biofuel with more tillers. As grains have typically decreased tiller number while undergoing domestication, we explored wild and domesticated strains of varying grains by doing a morphological analysis on tiller development. This thesis shows how the decrease of tillers through in domestication cereals shows diversity not only across maize, Sorghum, and Setaria, but also between lines of maize and Setaria species. …
