The effect of some factors that can affect quality characteristics of broccoli
florets in storage was evaluated. Quality characteristics of broccoli florets with
different rates of field nitrogen (N) application (0, 90, 180, and 270 Kg N/ha from
urea) were evaluated in modified atmosphere packaging (MAP) (B-900 Cryovac
film) storage...
The Oregon Processed Vegetable Commission (OPVC) is one of twenty-three commodity commissions that fall under the jurisdiction of the Oregon Department of Agriculture (ODA). In 2020, the OPVC was successfully awarded a 3-year grant under the FDA’s Specialty Crop Block Grant Program (SCBGP) to conduct ‘Market Research and Development to...
With the hot summers of recent years causing significant heat damage to broccoli heads within the Willamette valley, varietal screenings for newer and more heat tolerant varieties became necessary. Most commercially available broccoli varieties are bred for production within milder and more climatically stable regions, such as the Salinas Valley...
Studies were conducted on the mechanisms contributing to
resistance in broccoli, Brassica oleracea italica, to the garden
symphylan, Scutigerella immaculata (Newport). Differences in
resistance to symphylan injury were shown between five selected
broccoli cultivars. The hybrid cultivars, Crusader, Green Duke
and Bravo, showed a higher level of resistance to symphylans...
To determine the effect of bud pollination, compared to pollination
of open flowers and crossing, on field characteristics of broccoli progenies,
an experiment was conducted in 1974 and 1975 at Corvallis, Oregon.
Single plants of 55 broccoli lines were pollinated, using four methods,
i.e. bud pollination (BP), open flower pollination...
An inbred cabbage line (Brassica oleracea L. (Capitata group))
and an inbred broccoli line (B. oleracea L. (Italica group)) were
crossed. F₁ progeny were vigorous annuals. Of 3,260 F₂ plants, 250
were biennials and 70 developed cabbage heads. Of these 70, 32 were
annuals. Days to first visible buds of...
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...
Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...
