Energy Content Of Seeds Of Palmer’S Pigweed (Amaranthus Palmeri) In The Diet Of Scaled Quail (Callipepla Squamata) In Southeastern New Mexico, John L. Hunt, Matthew E. Grilliot, Troy L. Best, Isaac C. Castillo, Paige E. Eddington, Faith A. Johnson, Tyneshia L. Kilgore, Jacob H. Courson
Energy Content Of Seeds Of Palmer’S Pigweed (Amaranthus Palmeri) In The Diet Of Scaled Quail (Callipepla Squamata) In Southeastern New Mexico, John L. Hunt, Matthew E. Grilliot, Troy L. Best, Isaac C. Castillo, Paige E. Eddington, Faith A. Johnson, Tyneshia L. Kilgore, Jacob H. Courson
Journal of the Arkansas Academy of Science
Palmer’s pigweed (Amaranthus palmeri) is a common grassland plant that occurs across much of North America. It is often considered a weed but is an important source of food for many game birds. We analyzed the energy content of seeds of Palmer’s pigweed obtained from the crops of scaled quail (Callipepla squamata) collected from plains-mesa sand-scrub habitat in Eddy and Lea counties, New Mexico. Seeds were dried for 48 hours at 60°C to remove moisture and then analyzed for gross caloric value (i.e., energy content) in an oxygen bomb calorimeter. Energy content of seeds of Palmer’s …
Effect Of Tillage And Herbicide Treatments On Redvine (Brunnichia Ovata) Subterranean Morphology, E. C. Gordon, T. C. Keisling, L. R. Oliver, T. A. Castillo
Effect Of Tillage And Herbicide Treatments On Redvine (Brunnichia Ovata) Subterranean Morphology, E. C. Gordon, T. C. Keisling, L. R. Oliver, T. A. Castillo
Journal of the Arkansas Academy of Science
Redvine Brunnichia ovata (Walt.) Shinners is a perennial weed that reproduces from seed, rootstock, and rhizomes. Redvine infested areas that were exposed to different tillage practices, slicing techniques, and herbicide treatments were selected to excavate in order to observe rhizome and root morphology. When comparing tillage systems, deep tillage appeared to delay rhizome development following cultivation, but a characteristic branching occurred over time. Shallow cultivation (2.5 to 7.5m) concentrated rhizomes immediately below the depth of tillage; whereas, no-till areas concentrated rhizomes near the soil surface. Slicing the underground parts of redvine will not kill rhizomes if they are still attached …
Preliminary Evaluation Of A Dodder Anthracnose Fungus From China As A Mycoherbicide For Dodder Control In The Us, D. K. Cartwright, George E. Templeton
Preliminary Evaluation Of A Dodder Anthracnose Fungus From China As A Mycoherbicide For Dodder Control In The Us, D. K. Cartwright, George E. Templeton
Journal of the Arkansas Academy of Science
Dodder (Cuscuta spp.) is a noxious, parasitic, annual weed throughout most of the United States. A fungus used to control it in China was imported under permit for studies with U.S. dodder species in containment. The fungus, Colletotrichum gloeosporioides, sporulated on liquid and solid media at room temperature. Conidia from 7-12 day old cultures were diluted to 3.5 to 7 X 16⁶ spores ml^-1 for host range inoculations. Germination on water agar at 24 hrs was higher at 28 than 30 or 24 C. Inoculated plants were exposed to dew periods of 12-1 4 hrs at 24 or 28 C, …
Residual Effects Of N-K Fertilization Of Coastal Bermudagrass On Spring Populations Of Weed Species, R. A. Allured, E. C. Gordon, R. E. Frans, Lyell F. Thompson
Residual Effects Of N-K Fertilization Of Coastal Bermudagrass On Spring Populations Of Weed Species, R. A. Allured, E. C. Gordon, R. E. Frans, Lyell F. Thompson
Journal of the Arkansas Academy of Science
A "Coastal bermudagrass" (Cynodon dactylon L.) sod was treated during a five-year period with rates of N and K fertilizers ranging from none to high levels of both elements. In the spring of the sixth year differences in weed species and population densities among the treated plots were observed. Spring weed counts showed that high rates of N fertilizer reduced the number of weed species and the total broadleaf weed population density by 37 and 81%, respectively. The higher rates of K fertilizer also reduced the population density of common dandelion (Taraxacum officinale Weber) and yellow toadflax (Linaria vulgaris Hill),the …
