Exploring Gene Expression Patterns For Resilient Maize Lines Under Nitrogen Stress, Alice Guo
Exploring Gene Expression Patterns For Resilient Maize Lines Under Nitrogen Stress, Alice Guo
Honors Theses
Nitrogen plays a major role in the proper growth and development of maize and is therefore essential to crop production, being the most critical nutrient for achieving optimal yield. In previous field and greenhouse studies, we have found maize lines that differ in their resiliency to nitrogen stress. To identify the potential genomic regions associated with the differences in nitrogen deficiency resilience, Genome-Wide Association Studies (GWAS) were conducted. Based on a previous study, the most consistently resilient maize inbred lines within the Goodman-Buckler diversity panel have been identified as the lines A619 and A661, while the non-resilient inbred lines have …
Economic And Input-Use Efficiency Of Nitrogen Management Techniques In Non-Irrigated Maize Production, Katie J. Bathke
Economic And Input-Use Efficiency Of Nitrogen Management Techniques In Non-Irrigated Maize Production, Katie J. Bathke
Honors Theses
The efficiency of nitrogen (N) management has become a main concern in agricultural cropping systems for understanding the optimal N rate to help producers improve economically and reduce the exhaustion of natural resources environmentally. Nitrogen rates vary both temporally and spatially by the interactions of the soil environment and rainfall through a growing season. Thus, a site-specific approach can further optimize this variability with the understanding of the role soil variability plays in the N rate applied to a non-irrigated field. The objective of this study was to evaluate the various nitrogen treatments for their nutrient use efficiency and economic …
