Turmeric (Curcuma longa L.) is a rhizomatous herbaceous perennial plant belonging to the ginger family, Zingiberaceae. Currently, more than 80% of turmeric is produced by India and turmeric products are exported to numerous ...

Birdsfoot Trefoil (Lotus corniculatus) Cultivars Adaption Concerning Drought and Heat Tolerance Enabling the Expansion of Geographic Adaptation to include Alabama with Disease Resistance to Fungi and Nematodes as well as Herbicide Injury 

Moye, Hayden Hugh Jr. (2018-11-27)
Lotus corniculatus L., birdsfoot trefoil (BFT), is a common flowering plant in the Fabaceae family, native to grasslands in temperate Eurasia and North Africa. BFT is a perennial herbaceous plant, similar in appearance ...

Boron and Calcium Effects on Runner Peanut Production 

Van Cleave, Ashleigh (2019-04-16)
Calcium (Ca) and boron (B) deficiencies in peanut (Arachis hypogaea L.) reduce seed quality, yield, and crop value. Southeastern U.S. Coastal Plain soils are inherently low in Ca and B, requiring supplementation to reach ...

Characterization of Phosphorus in Poultry Litter and Determination of Phosphorus Extraction Efficacy of Extractants 

Dey, Poulomi (2020-12-10)
Poultry litter (PL) is used as a nutrient source for row crops, horticultural crops, and pasture production. Typically, PL is a mixture of poultry feces, bedding materials, spilled grain and feather than can potentially ...

Compaction Susceptibility of Select Alabama Piedmont and Upper Coastal Plain Ultisols 

Lane, Abigail S. (2018-11-15)
The U.N. categorizes soil compaction as the most important type of physical soil degradation because of soil productivity and quality loss. Subsoil compaction causes great concern because it is difficult to remediate, ...

A Comparison of Morphological Maturity Methods in Upland Cotton for the Optimization of Crop Production and Breeding Systems 

Peavy, Elliott (2021-12-03)  ETD File Embargoed
The indeterminacy of upland cotton (Gossypium hirsutum L.) necessitates methods for evaluating its reproductive status and progress. There is no universally accepted agronomic method for assessing cotton maturity and the ...

Comparison of Poultry Litter and Commercial Fertilizer Rate and Application Timing on Environmental Nitrogen Loss, Corn Grain Yield, and Mineral Composition 

Singh, Rajveer (2020-07-30)
For efficient use of poultry litter (PL) as a nutrient source, it is critical to balance the amount of nitrogen (N) needed to maximize corn (Zea Mays L.) grain yield while reducing N loss to the environment. Besides, there ...

Cover Crop Effects on Insect Dynamics in Cropping Systems of the Southeastern U.S. 

Akins, Joseph (2020-11-16)
Evidence suggests winter cover crops could be useful for augmenting conservation biological control of insect pests in southeastern row crop systems. Management decisions such as selection of cover crop species and irrigation ...

Cover Crop Effects on Soil Hydrology 

Bonilla, Rodolfo (2022-05-09)
Cover crops are known for their positive and significant effects on soils. They contribute to growing subsequent crops, reducing soil erosion, increasing water infiltration, and improving nutrient management. Cover crops ...

Cover Crop Effects on Urease Inhibitors 

Hull, Noah (2018-07-23)
Urease inhibitors continue to be introduced in the agricultural market, and thus new studies with these products are warranted. The objective of this research was to examine the utility of these inhibitors for reducing ...
