Effect of pruning and training time on yield components and cold hardiness of 'Marion' blackberry

Creator:: Bell, Neil (Neil Charles), 1961-
Abstract:: The effect of primocane removal and training time on yield components and cold hardiness of 'Marion' trailing blackberry was studied. In 1991, primocanes were either not cut, or cut at ground level from plants on a single occasion at one month intervals from late April to late July. Four canes...

Geochemical characteristics of iron-manganese nodules in seasonally-saturated soils of the Willamette Valley, Oregon

Creator:: Seter, Lisa M.
Abstract:: This study was initiated to characterize the distribution of Fe-Mn nodules and to elucidate trends of Fe, Mn, and P relative to the intensity of the annual cycles of reduction and oxidation. Nodules were enriched in Fe, Mn, and P relative to the soil matrix making them an integral part...

Effect of temperature and photoperiod on growth and development of the filbert leafroller, archips rosanus L. (lepidoptera: Tortricidae) in the Willamette Valley of Oregon

Creator:: Al-Zabidi, Ahmed Hizam, 1953-
Abstract:: Role of temperature and photoperiod on development of the filbert leafroller, Archips rosanus L., (Lepidoptera: Tortricidae) from the Willamette Valley, Oregon was studied in the laboratory and in the field. Both temperature and photoperiod had a significant influence on the developmental rate of this species from neonate larva to adult...

Influence of movement corridors on enclosed populations of the gray-tailed vole : do immigrants affect reproduction and dispersal of residents in a patchy environment?

Creator:: Davis-Born, Renee
Abstract:: I monitored demography, movement, and reproductive behavior of gray-tailed voles, Microtus canicaudus, in experimental habitat patches with and without corridors. I tested the hypotheses that reproductive rate, juvenile recruitment, and population size and growth rate would be affected negatively by immigrants that were introduced to resident groups (+ male and...

Nitrogen available to winter wheat as influenced by previous crop in a moist xeric environment

Creator:: Qureshi, Maqsood Hassan
Abstract:: Rotating wheat with other crops is a common practice in the Willamette Valley of western Oregon. Depending upon previous crop and soil type, current N fertilizer recommendations for wheat in the Willamette Valley vary widely. Excessive fertilizer poses environmental risk, whereas lower N inputs than required by the crop represent...

Evaluation of botanical diversity in Oregon vineyards

Creator:: Schonenberger, Patrik M.
Abstract:: Three different ground cover management strategies were compared at the OSU research vineyard near Alpine, Oregon. Botanical diversity was actively increased in two diverse treatments. Another treatment was botanically uniform and contained creeping bentgrass (Agrostis stolonifera). The composition of the vineyard floor vegetation and grapevine performance as affected by the...

Aggregation, bulk density, compaction, and water intake responses to winter cover cropping in Willamette Valley vegetable production

Creator:: Buller, Gilbert L.
Abstract:: Many agricultural sustainability issues are related to biological processes which are central to the ecological function of soils. Soil physical properties are the architecture in which these processes are carried out. Cover crops hold promise as one of the techniques which can ameliorate poor soil structure and improve bulk density...
