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...
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...
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...
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...
Central Oregon is the primary U.S. hybrid carrot seed production area, supplying seed to the domestic fresh market carrot industry. Approximately 85 percent of the hybrid carrot seed planted in the United States is grown
in Jefferson and adjoining counties. The Madras and Culver areas support most of the carrot...
