Effects of amount of applied water and frequency of irrigation
on head rot and yield of three broccoli cultivars were evaluated in
1987 and 1988. Two irrigation frequencies were established with a
line-source sprinkler system for 5.5 weeks during heading. The low-frequency
experiment was watered once per week and the...
Green manures, soil solarization, and long rotations with crops not susceptible to Verticillium wilt are among the disease management tactics currently under investigation as alternatives to chemical fumigation of soil. The effect of a broccoli green manure on soil microsclerotial populations of three isolates of Verticillium dahliae and on Verticillium...
Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai var.
Crimson Sweet) was seeded in a commercial peat mix in multicell
containers (72 cells-tray⁻¹, 40 cm³-cell⁻¹) in July 1989 and April 1990.
In 1989, the medium was amended with CaC0₃ at 10% w:v. In 1990, no
CaC0₃ amendment was made. Watermelon seedling...
Field and greenhouse experiments were conducted in 1996 and 1997 to evaluate the effects of integrating conservation tillage and cover cropping on broccoli production as well as agroecological parameters. A field experiment was conducted during 1996-97 at the Oregon State University Horticulture Research farm near Corvallis, OR. The specific objectives...
Lack of stability of soil aggregates for water
movement is a major problem in arid soils due to low
organic matter and higher sodium contents. Soil
amendments for improving stability of structure and
increasing infiltration of water are essential to solve
water management problems in these areas.
Different rates of...
Yield, occurrence of root canker (B deficiency), and leaf nutrient concentrations of the Morse strain of ‘Detroit Dark Red’ table beet (Beta vulgaris L.) as influenced by combinations of lime and N, B, and P fertilizers were evaluated in three studies. Greatest total yields and most favorable distribution of root...

Experiments at the North Willamette Experiment Station have evaluated response of vegetables to lime and other fertilizers since 1970. The soils are moderately acid (pH 5.4 to 5.6), high in P, and better drained than most soils used for vegetable crop production in western Oregon. Typical soil acidity problems such...
