Cover crop and rotation intensity effects on soil health and yield in corn-soybean cropping systems
(University of Missouri--Columbia, 2020)
In the Midwest, corn-soybean [Glycine max (L). Merrill] is the dominant biennial cropping system, which covers approximately 75% of the arable land surface (Hatfield et al., 2007; Plourde et al., 2013). The growing demand for corn (Zea mays L...
Cotton and maize primary root growth responses to water deficit : comparative physiological and metabolic analysis
(University of Missouri--Columbia, 2019)
Cotton (Gossypium hirsutum L.) and maize (Zea mays L.) are important economic crops that can suffer significant yield loss under drought. Cotton and maize root systems have fundamentally different architectures, in addition ...
Nested association mapping and accuracy of predicting genomic breeding value for agronomic and seed composition traits in three interspecific soybean populations
(University of Missouri--Columbia, 2019)
increment between 300 and 390 individuals (1%). Marker density had little impact on the prediction accuracy across traits, with a significant increment in prediction accuracy up to 1423 markers (18.5%). The training population design Across all families had...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Switchgrass responses to manganese availability
(University of Missouri--Columbia, 2019)
Manganese (Mn) is an essential micronutrient and has a broad range of functions for all plant growth and reproduction. It plays a crucial role in NAD-ME C4 photosynthesis, including as a constituent of the water splitting ...
Biodiversity of ants (Hymenoptera: Formicidae) in restored grasslands of different ages
(University of Missouri--Columbia, 2006)
Grasslands are an endangered ecosystem. Unfortunately, few studies monitoring the health of these grasslands have included arthropods, thus leaving out a vital biodiversity component. Ants have been proven to be reliable ...
