In Southern Oregon, grass seed production occupies a small acreage, but is an important part of agronomic crop production. The high value of sod quality bentgrass seed (Agrostis palustris Huds.) led to some growers supplementing soil fertilizers with foliar fertilizers in an attempt to increase seed yield. However, this practice...
The objectives of this trial were to:
1. Compare onion yield under surge irrigation with continuous flow irrigation.
2. Estimate irrigation efficiency under surge irrigation and continuous flow irrigation.
3. Compare estimates of nitrogen leaching under surge irrigation with continuous flow irrigation.
The potential of mechanically applied straw mulch to reduce nutrient, pesticide and sediment losses from furrow irrigated onions and increase water use efficiency was evaluated on a Nyssa silt loam with three percent slope. Nitrogen and phosphorus losses in the runoff were of particular interest, both because of their economic...
Surface crusting of soil after planting can result in poor emergence and reduced stands. The use of polysaccharides and polyelectrolytes for soil conditioning has been found to improve seedling emergence. This trial evaluated the use of a molasses and nutrient based soil conditioner (Bright Sun Soil Booster, Cargill Inc., Minneapolis,...
This report includes information concerning experimental use of unregistered pesticides or unregistered uses of pesticides. Experimental results should not be interpreted as recommendations for use. Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
The problem addressed in this paper is that of usability of the Petri Net Editor used to create applications in the Objex framework. This editor puts a lot of burden on the user, in that the user needs to remember all the GUI resources previously created for the application, has...
A structural active-object systems (SAOS) is a, transition-based object-oriented system consisting of a collection of interacting structural active objects (SAOs), which can be structurally and hierarchically composed from their component SAOs. The behaviors of SAOs are determined by the transition statements provided in their class definitions. Various concurrent systems such...
A problem with a number of available parallel programming tools proposed and implemented by researchers is that there has been little consideration of the impact of the user interface on users outside the field of computer science.
In this paper we propose and implement Banger, an extension to the Parallel...
The coverage of a learning algorithm is the number of concepts that can be learned by that algorithm from samples of a given size. This paper asks whether good learning algorithms can be designed by maximizing their coverage. The paper extends a previous upper bound on the coverage of any...
