2012 International Pinot Noir Celebration Program, International Pinot Noir Celebration

Willamette Valley Archival Documents - IPNC

This document is the 2012 program for the International Pinot Noir Celebration (IPNC), held annually on the campus of Linfield College in McMinnville, Oregon. The program contains a detailed schedule of the celebration’s major events, presentations, and meals, as well as information regarding guest speakers and chefs visiting the campus. The program also includes a short description of all participating wineries for 2012, both foreign and domestic, along with a listing of the IPNC board of directors and all major supporters and contributors to the event.

Ecosystem Services: The Significance Of Contributions By Invasive Plant Species, Stephen L. Young

West Central Research and Extension Center, North Platte

A symposium was organized to investigate the area of invasive plant species and ecosystem services and further our understanding of the contributions that invasive plants are making to ecosystem services, which, to date, has received limited attention. The following symposium articles address three important areas of assessing the effects of invasive plant species on ecosystem services. Karie Decker et al., in “Landuse, landscapes, and biological invasions,” introduce the concept of resilience in natural systems and use an analysis of the nonnative plants and land use types in Nebraska to emphasize the importance of predicting and quantifying changes in ecological structure, …

Effects Of Crop Residue Removal On Soil Water Content And Yield Of Deficit-Irrigated Soybean, Simon Van Donk, Timothy M. Shaver, James L. Petersen, Don Davison

West Central Research and Extension Center, North Platte

Reduced tillage, with more crop residue remaining on the soil surface, is believed to conserve water, especially in arid and semi-arid climates. However, the magnitude of water conservation is not clear. An experiment was conducted to study the effect of crop residue removal on soil water content, soil quality, and crop yield at North Platte, Nebraska. The same field plots were planted to soybean (Glycine max) in 2009 and 2010. There were two treatments: residue-covered soil and bare soil. Residue (mostly corn residue in 2009 and mostly soybean residue in 2010) was removed every spring from the same …

Seed Reduction In Prairie Cordgrass, Spartina Pectinata Link., By The Floret-Feeding Caterpillar Aethes Spartinana (Barnes And Mcdunnough), Jarrad R. Prasifka, D. K. Lee, Jeffrey Bradshaw, Allen S. Parrish, Michael E. Gray

Panhandle Research and Extension Center

Insect damage to prairie cordgrass, Spartina pectinata Link., is conspicuously high in Illinois, where attempts to collect native seed show the majority of spikelets damaged with small holes. Dissection of spikes during summer reveals minute caterpillars boring though glumes and feeding on florets inside. In 2009–2010, panicles of prairie cordgrass from across its native range were used to estimate the percentage of insect-related damage and losses to seed production. Collections of caterpillars from panicles and stems were used to identify one floret-feeding species, estimate its distribution in the central USA, and assess its feeding patterns within spikes. Insect feeding damaged …

Comparative Growth Of Spring-Planted Canola, Brown Mustard And Camelina, A. D. Pavlista, D. D. Baltensperger, T. A. Isbell, G. W, Hergert

Panhandle Research and Extension Center

With increased emphasis for diesel substitution, production of brown mustard (Brassica juncea), canola (Brassica napus) and camelina (Camelina sativa) used as biodiesels may increase in the High Plains. Since these are new crops to this region, understanding their growth is critical for their acceptance. The objective was to elucidate the growth pattern of these crops when spring-planted in western Nebraska. Field trials were conducted in 2005, 2006 and 2007 with early May planting. Plots were seeded 2 cm deep at 200 plantsm−2. Four plants were destructively sampled at about 28, 40, 53, 61, and …

Government Insurance Program Design, Incentive Effects, And Technology Adoption: The Case Of Skip-Row Crop Insurance, Joshua D. Woodard, Alexander Pavlista, Gary D. Schnitkey, Paul Burgener, Kimberley A. Ward

Panhandle Research and Extension Center

Can the availability of poorly-designed government insurance alter technology adoption decisions? A theoretical model of technology adoption and insurance incentive effects for a high- and low-risk technology is developed and explored empirically using a unique dataset of skip-row agronomic trial data. A multivariate nonparametric resampling technique is developed, which augments the trial data with a larger dataset of conventional yields to improve estimation efficiency. Skip-row adoption is found to increase mean yields and reduce risk in areas prone to drought. RMA insurance rules have incentive-distorting impacts which disincentivize skip-row adoption.

Research Achievements And Adoption Of No-Till, Dryland Cropping In The Semi-Arid U.S. Great Plains, Neil C. Hansen, Brett L. Allen, R. Louis Baumhardt, Drew J. Lyon

Panhandle Research and Extension Center

The Great Plains region of the United States is an area of widespread dryland crop production, with wheat being the dominant crop. Precipitation in the region ranges from 300 to 500 mm annually, with the majority of precipitation falling during hot summer months. The prevailing cropping system is a two-year rotation of wheat and summer fallow. The adoption of no-till practices has resulted in greater precipitation storage and use efficiency, which has led to greater cropping intensity, higher productivity, more diverse crop rotations, and improvements in soil properties. In Colorado, for example, a no-till rotation of winter wheat–maize–fallow increased total …

The Economic Impact Of The New Insensitive Sorghum Cultivars In The Dairy Market Of Nicaragua, Gabriel Garcia Gomez

INTSORMIL Scientific Publications

This thesis estimates the benefits and returns to consumers, processors, producers and society of the new insensitive sorghum cultivars used for the dairy production in Nicaraguan. Many dairy producers also sell their grain so sorghum production is a multi-product activity.

The breeding project of INTA developed cultivars for simultaneous use in dairy and grain production. Its first release was Pinolero-1 developed during the Nicaraguan civil war. This cultivar was rapidly adopted by farmers after the end of the war in 1990. Subsequently, five more new cultivars have been released. We consider their combined effects.

Through field surveys, we calculated the …
