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...

The effects of light on photosynthesis and rooting of leafy cuttings of Pisum sativum L.

Creator:: Davis, Tim D.
Abstract:: The effects of light incident on leafy cuttings is quite complex because' light influences several factors which may affect root formation. One effect of light is to influence the carbohydrate status of the cutting by influencing photosynthesis. The role of current photosynthate in the rooting of leafy cuttings is uncertain....

Effect of boron on seven vegetable crops grown on two soil types

Creator:: Oneida, Kelly Ann
Abstract:: Boron deficiency or toxicity can reduce yield and quality of vegetables. Seven vegetable crops, varying from low to high boron requirements were grown in field plots at Corvallis in 1987. Leaf-B and yield components of green bean, cucumber, potato, carrot, tomato, broccoli and table beet were examined under conditions of...

Effects of nitrogen source, rate and a nitrification inhibitor on soil nitrogen status and mineral composition of strawberry

Creator:: Marion, Carol I.
Abstract:: Three rates of urea, urea-DCD, and NH₄N0₃ were soil applied in April and August 1986 to strawberry selection OR-US 4930 and cultivar 'Sumas' to determine effects of the nitrification inhibitor dicyandiamide (DCD) and nitrogen source and rate on soil NH₄ and N0₃ levels, fruit yield and quality, and mineral composition...

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...
