In yr 2, a total of 1,230 heifers were randomly assigned to 1 of 4 pastures; 2 received a supplement providing 100 g/d of Ca propionate (1.4 kg/d, 20% CP) 2 d before through 19 d after bull exposure and 2 did not in a 25-d breeding …

Pollen Interception By Linyphiid Spiders In A Corn Agroecosystem: Implications For Dietary Diversification And Risk-Assessment, Julie A. Peterson, Susan Romero, James D. Harwood

West Central Research and Extension Center, North Platte

Dietary diversification, including consumption of plant tissues such as pollen, can enhance the fecundity of generalist predators, resulting in improved control of pest prey. Supplemental pollen feeding has been observed in many natural enemies, including sheet-web spiders (Araneae: Linyphiidae), which represent a major component of food webs in agroecosystems. Their horizontal, ground-based webs have the potential to intercept pollen grains during anthesis of crop plants, providing the opportunity for consumption of pollen to occur. In laboratory feeding trials, Frontinella communis and Tennesseellum formicum (Araneae: Linyphiidae) readily fed on pollen grains dusted on their webs, with 82 and 92% of spiders …

Education Faculty Books and Book Chapters

"On May 23, 2008, farmworkers and student activists gathered with corporate executives, U.S. Senator Bernie Sanders (Vermont), and dozens of members of the local and national media for a standing room-only press conference under the dome of the U.S. Capitol announcing an accord between the Burger King fast food corporation and a Florida farmworker organization, the Coalition of lmmokalee Workers (CIW). Weeks earlier, Burger King made headlines when a spate of malicious Internet postings defaming the CIW and its supporters were traced back to a company executive, and news surfaced that the company hired an unlicensed private investigator to infiltrate …

Whole Genome Wide Expression Profiles Of Vitis Amurensis Grape Responding To Downy Mildew By Using Solexa Sequencing Technology, Jiao Wu, Yali Zhang, Huiqin Zhang, Hong Huang, Kevin M. Folta, Jiang Lu

School of Information Faculty Publications

Background: Downy mildew (DM), caused by pathogen Plasmopara viticola (PV) is the single most damaging disease of grapes (Vitis L.) worldwide. However, the mechanisms of the disease development in grapes are poorly understood. A method for estimating gene expression levels using Solexa sequencing of Type I restriction-endonuclease-generated cDNA fragments was used for deep sequencing the transcriptomes resulting from PV infected leaves of Vitis amurensis Rupr. cv. Zuoshan-1. Our goal is to identify genes that are involved in resistance to grape DM disease.

Results: Approximately 8.5 million (M) 21-nt cDNA tags were sequenced in the cDNA library derived from PV pathogen-infected …

Studies On Ecophysiological Responses Of Durum Wheat Genotypes Under Water Deficit Conditions., Ali Akbar Moayedi

Student Works (2010-2019)

Water is the main component in the make-up of plants and serves as the solvent, which transports minerals and dissolved carbohydrates throughout the plant. However, the ecological and physiological responses of plants to water limitation vary at different developmental stages and limits crop production and yield in crops. Therefore, investigation of the plant response to drought at its different developmental stages can be useful to overcome the negative effects of water stress in different plant growth stages. In addition, although, drought stress has been well documented as an effective parameter in decreasing crop production in arid and semi arid regions, …

The Effect Of Field Pea (Pisum Sativum L.) Companion Crop Management On Red Clover (Trifolium Pratense L.) Establishment And Productivity, Branko Cupina, Dorde Krstic, Aleksandar Mikic, Pero Eric, Savo Vuckovic, Borivoj Pejic

Turkish Journal of Agriculture and Forestry

Field pea (Pisum sativum L.) has the potential to be a suitable companion crop for the establishment of red clover (Trifolium pratense L.), as it is fast growing and is harvested early, and thus reduces the duration of competition and allows light to be transmitted through its canopy to an undersown species more so than other companion crops such as small grains. The aim of this study was to determine the suitability of field pea as a companion crop for red clover, and in particular to determine the effect of pea cultivar and plant population density. The field experiment comprised …
