Effects of tillage-induced soil compaction on carrot seedlings emergence and yield

Creator:: Thomasson, James E.
Abstract:: The effects of five tillage treatments on soil bulk density and mechanical impedance were examined on Newburg sandy loam soil in the Willamette Valley, Oregon, in 1987. Subsequent effects on seedling emergence and yield of carrots (Daucus carota L., cvs. Orlando Gold and Royal Chantenay) were also measured. Mechanical impedance...

Influence of spacing and crown recession on wood quality of intensively-managed young-growth Douglas-fir

Creator:: Robbins, James M.
Abstract:: Intensive management of young-growth Douglas-fir plantations has emphasized volume growth over wood quality. A better understanding of the variables that affect wood quality is needed so that wood quality and stand yield can be systematically combined into a silviculture program. This experiment utilized two separate experiments to establish the relationship...

Full Text:: density, 1 :2 rectangularity of spacing did not affect indicators of \NOOd quality relative to 1: 1

Corn (Zea mays L.) yields as influenced by nitrogen, row spacing and intercropped ryegrass (Lolium multiflorum)

Creator:: Wivutvongvana, Paibool
Abstract:: Two field corn experiments were conducted on a Woodburn silt loam soil near Corvallis, Oregon, in 1972-1973 to investigate the effects of certain soil management practices on the yield and performance of corn (Zea mays L.). Experiment I involved variables that included three corn row spacings (76, 114, and 152...

Effect of cooking on the fiber content of cauliflower and carrots

Creator:: Loghmani, Emily S.
Abstract:: This study investigated the effect of cooking on the neutral detergent fiber (NDF) content of cauliflower and carrots. For each replication the vegetable was divided in half to serve as its own control. One half was used raw and the other half was cooked in 60 ml of distilled water...

Estimation of Soil Particle Size Distribution using CT Scans

Creator:: Boath, Max E.
Abstract:: Remote sensing techniques have been applied extensively in geospatial investigations, but their use in measuring soil physical attributes has been far less explored. Soil particle size distributions (PSD) are indispensable in modeling pedological and hydrological processes as well as biodiversity. However, estimation of PSD via gravimetric measurement methods, the standard...

The effect of row spacing, rate and date of planting on yield and yield components of four winter wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Nadjib, Benacef
Abstract:: Four winter wheat cultivars, Bezostaya, Maris-Hobbit, Roussalka and Stephens, selected on the basis of the diversity of their pedigree and phenotype, were planted at Hyslop Experiment Station near Corvallis in Western Oregon to study their performance at three different row spacings (10, 16 and 24 cm), three seeding rates (100,...

Soil Water Tension Irrigation Criteria Affects Both Stevia Rebaudiana Leaf Yield and Leaf Steviol Glycoside Composition

Creator:: Parris, Cheryl A.
Abstract:: Stevia (Stevia rebaudiana) is a perennial herbaceous plant native to Paraguay and used traditionally by the native Guarani peoples for centuries to sweeten medicinal teas. Stevia has only been commercially cultivated over the past 50 years and cultural practice information suitable for implementation by growers is limited. Currently stevia’s commercial...
