The Pine Forest Mountains lie within the northern part of the Basin and Range province, near Denio, northwestern Nevada. They are tilted, fault block mountains composed in part of schists and quartzites of Triassic-Jurassic (?) age. In addition, they are intruded by Cretaceous diorites, granodiorites, and quartz monzonites which are...

This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...
A suitable method for the utilization of shrimp processing waste was investigated. The shrimp waste, which consisted of shell, viscera, and residual meat particles, was dried into a pink meal. This meal contained 5.4 percent moisture, 23.5 percent ash, 4. 1 percent crude lipid, 36. 3 percent actual protein, and...
Cereal residues suppress the development of small seeded, summer annual weeds. The focus of this study was to determine whether cereal residues can be used to suppress weeds in cucumber production systems in the Pacific Northwest. In the first of three experiments, cereal residues of fall-planted, spring-killed cover crops suppressed...
Puncturevine is on the loose in western Oregon. Puncturevine is an annual in our climate, and it produces seeds that can contaminate snap beans headed to the cannery. Puncturevine also has very persistent seed with erratic emergence over several seasons. When spotted, puncturevine should be eradicated.
Weeds in snap beans drag down yield and contaminate products sent to processors or markets. They may even make it impossible to harvest the crop mechanically. It is worth the effort to be proactive when managing weeds in row crops. Proactive rather than reactive approaches are essential to successful management...
