Nitrogen Fertilizer Showed Little Effect On First- And Second-Year Corn Yield And Quality Following Alfalfa, Bailey Brent Shaffer Aug 2021

Nitrogen Fertilizer Showed Little Effect On First- And Second-Year Corn Yield And Quality Following Alfalfa, Bailey Brent Shaffer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Silage corn (Zea mays L.) following alfalfa (Medicago sativa L.) is a common crop rotation in Utah and southern Idaho. This is done, in part, to take advantage of residual nitrogen (N) fixed by bacteria that work in symbiosis with the roots of alfalfa. After alfalfa is terminated, much of the N that was fixed by the plant is released into the soil and becomes available for use by the rotational crop. This reduces the amount of N fertilizer that growers need to apply. The Utah Fertilizer Guide currently recommends an N credit to a rotational crop following …


Translating -Omics Big Data: Comprehensive Understanding Of Host-Pathogen Interactions To Control Bacterial Blight In Alfalfa Using Computational Approaches, Raghav Kataria Apr 2021

Translating -Omics Big Data: Comprehensive Understanding Of Host-Pathogen Interactions To Control Bacterial Blight In Alfalfa Using Computational Approaches, Raghav Kataria

Student Research Symposium

Plant infectious diseases are a major threat to the crops, owing to economic losses to the agriculture industry worldwide. Molecular interactions between the host and pathogen play a critical role in understanding the basis of pathogenesis. Majority of the Pseudomonas syringae strains are known to cause frost injury in plants, amongst which, P. syringae pv. syringae ALF3 is asserted to be a causal organism of bacterial stem blight in Medicago sativa (alfalfa). We elucidated the genome-scale host-pathogen interactions (HPIs) between alfalfa and P. syringae using two intense computational approaches: interolog (homology-based) and the domain-based method (based on 3D structure of …
