Effects of irrigation and nitrogen on cauliflower development, yield and quality

Creator:: Bratsch, Anthony D.
Abstract:: Field experiments were conducted with cauliflower (Brassica oleracea var. botrytis cv. Snowball Y ) to determine crop development, yield, quality and maturity response to various seasonal water levels, and to specific water stress timing in relation to curd initiation. The effects of nitrogen rate, timing, and source and the application...

Modeling purple nutsedge (Cyperus rotundus L.) growth : preliminary evaluation of light intensity, soil moisture and herbicide effects

Creator:: Amerasinghe, A. A. L.
Abstract:: Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the most troublesome perennial weeds of agricultural lands in tropical and some temperate regions. This research sought to determine the effects of timing of herbicides, shading, and soil moisture on plant population growth and tuber production of purple nutsedge...

Nitrogen dynamics in field grown comice pears

Creator:: Sanchez, Enrique E.
Abstract:: The dynamics of N was studied in field grown Comice/Provence quince BA29 pears in Medford, Oregon. Total tree biomass, N content, and ¹⁵N evaluations suggest that young pears require little N (48 kg N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was remobilized into new...

Onion (Allium cepa L.) cultivar tolerance to bromoxynil

Creator:: Madrid, Modesto T.
Abstract:: In onions, sensitive cultivars diminish the usefulness of the selective herbicide bromoxynil. Tolerant cultivars can overcome this limitation. A better understanding of the biochemistry, physiology and genetics of bromoxynil tolerance could lead to improved weed control programs in onions. Onion cultivar response to bromoxynil was studied under greenhouse conditions. Tolerant...

Glyphosate activity as affected by spray drop size and leaf coverage

Creator:: King, Wayne O.
Abstract:: Bean shoot parts that respond to glyphosate (N- (phosphonomethyl)glycine) in ways useful for bioassay were determined by applying glyphosate doses of 3.8 to 60.3 ug ae per plant to the simple leaves when the first trifoliolate leaflets were about 1 cm long. Dry weights of parts that were almost fully...

Diagnostic approaches to evaluate nutrient status, partitioning, mineral dynamics, and relationships with yield and fruit quality of 'Valencia' orange trees

Creator:: Tami, Mohamed
Abstract:: Five nutritional aspects of 'Valencia' orange production in Agadir, Morocco during 1989-1991 were evaluated: 1) the effect of N and K on yield and fruit quality, 2) leaf sampling time and diagnostic approaches to optimize mineral nutrition, 3) mass and mineral partitioning within individual trees, 4) K-Rb relationships, and 5)...

Water partitioning and respiration activity of dormant grape buds

Creator:: Gardea, Alfonso A.
Abstract:: Dormancy of 'Pinot Noir' grapevines was characterized. Primary buds required ca 300 cumulative chilling hours (CCH) to initiate the transition from endodormancy to ecodormancy, which occurred in mid November. Additional chilling, up to 1000 CCH, improved budbreak. Changes in bud water content were estimated by gravimetric and spectroscopic methods. Total,...

Nitrogen use in container-grown woody ornamentals

Creator:: Sandrock, David Ray, 1971-
Abstract:: Lasting, effective solutions to nitrogen (N) loss from container nurseries must address layers of complexity ranging in scale from whole system nursery management to gene expression. Group-based On-site Active Learning (GOAL) was developed to aid nursery managers and related stakeholders (e.g. neighbors, policy makers, regulating agencies, researchers) in developing a...
