Impact Of Automated Guidance For Mechanical Control Of Herbicide-Resistant Weeds In Corn, Terry Griffin, James M. Lowenberg-Deboer Oct 2017

Impact Of Automated Guidance For Mechanical Control Of Herbicide-Resistant Weeds In Corn, Terry Griffin, James M. Lowenberg-Deboer

Journal of Applied Farm Economics

This study evaluated the feasibility of reintroducing mechanical weed control as an alternative for herbicide-resistance weed infestations. The production practice tested included row cultivation with a separate banded spray application using high-accuracy automated guidance systems. A range of ground speeds were tested for the row cultivation operation, each with a different per acre cost and timeliness penalty. A typical eastern Corn Belt farm with a rotation of corn and soybean served as the base for the linear programming model. It was found that if the farmer was willing to reintroduce tillage, row cultivation conducted at higher operating speeds in conjunction …


Another Route For Amino Acid Production?: Reverse Genetic Probing For A Functional Cytosolic Shikimate Pathway In Plants, Gabrielle C. Buck, Joseph Lynch, Natalia Dudareva Aug 2017

Another Route For Amino Acid Production?: Reverse Genetic Probing For A Functional Cytosolic Shikimate Pathway In Plants, Gabrielle C. Buck, Joseph Lynch, Natalia Dudareva

The Summer Undergraduate Research Fellowship (SURF) Symposium

The shikimate pathway is a metabolic pathway that produces the three aromatic amino acids—phenylalanine, tryptophan, and tyrosine—which are essential to human diets and necessary for many plant functions. Consequently, the shikimate pathway is commonly targeted for antibiotic and herbicide strategies as well as genetic engineering in several fields. This pathway is known to be localized in the plastids, or double membrane-bound organelles, of plant cells; however, there is enzymatic evidence of another shikimate pathway in the cell fluid, or cytosol. To determine whether a complete cytosolic shikimate pathway exists, we used a modified gene for the first enzyme of the …

Potassium Applications And Yellow Shoulder Disorder Of Tomatoes In High Tunnels, Elizabeth Maynard, Israel S. Calsoya, Jill Malecki Jan 2017

Potassium Applications And Yellow Shoulder Disorder Of Tomatoes In High Tunnels, Elizabeth Maynard, Israel S. Calsoya, Jill Malecki

Purdue Fruit and Vegetable Research Reports

Tomatoes grown in unheated high tunnels can suffer significant loss in quality due to yellow shoulder disorder, particularly in susceptible varieties. This paper reports on a preliminary trial to determine whether incidence and severity of the disorder could be influenced by applying potassium fertilizers. Plots with higher leaf potassium content tended to have less fruit with severe yellow shoulder disorder, but increasing the amount of potassium fertilizer applied did not significantly reduce the disorder. From this study it isn’t possible to make specific recommendations for reducing yellow shoulder disorder with potassium applications.

Muskmelon Variety Trial In Southwest Indiana — 2016, Wenjing Guan, Dennis Nowaskie

Purdue Fruit and Vegetable Research Reports

This is a compilation of 21 research trial reports from four land-grant universities in the Midwestern United States. Crops include cantaloupe, pickling cucumber, pepper, potato, pumpkin, summer squash and zucchini, sweet corn, tomato, and watermelon. Somecrops were evaluated in high tunnels or hoophouses. Most trials evaluated different cultivars or varieties. One report addressed plant spacing for sweet corn and one addressed soil block for production of tomato seedlings. A list of vegetable seed sources and a list of other online sources of vegetable trial reports are also included.

Midwest Vegetable Trial Report For 2016, Elizabeth Maynard, Brad Bergefurd

Purdue Fruit and Vegetable Research Reports

This is a compilation of 21 research trial reports from six land-grant universities in the midwestern United States. Crops include dry beans, cantaloupe, cucumber, pepper, pumpkin, sweet corn, summer squash, winter squash, strawberry, tomato, watermelon, and winter melon. Several crops were evaluated in high tunnels or hoop houses. Most trials evaluated different cultivars or varieties. Three reports addressed specific growing practices: the use of poly-coated urea to supply nitrogen to sweet corn, potassium fertilization for high tunnel tomatoes, and use of cereal rye cover crop in butternut squash.
