The effects of nitrogen, potassium and chloride on nutrient composition in Russet Burbank potatoes (Solanum tuberosum)

Creator:: Murarka, Ishwar P., 1942-
Abstract:: Three greenhouse experiments were designed to measure the effects of N, K and Cl on the nutrient uptake by Russet Burbank potatoes (Solanum tuberosum). A Deschutes sandy loam soil from Powell Butte area in Central Oregon, low in potassium, was used to study these effects. Nitrogen applications produced significant increases...

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...

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...

Growth in herbaceous perennials

Creator:: Nakajima, Rie
Abstract:: Several studies of herbaceous perennials have addressed the effects of environmental factors during and after production, inherent cold hardiness, and post-harvest handling procedures to enhance flowering and growth during establishment. The regrowth of both woody and herbaceous forage plants following establishment is reported to be directly related to reserve-nitrogen content....

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)...

Influence of nitrogen form ratio and calcium on greenhouse and field performance of watermelon

Creator:: Lamb, Michael J.
Abstract:: 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...

Effect of solution nitrogen and phosphorus on growth, carbon allocation and nitrogen fixation of red alder seedlings

Creator:: Lipp, Cynthia C.
Abstract:: The effect of solution nitrogen (N) and phosphorus (P) concentrations on biomass production and N₂ fixation of red alder (Alnus rubra Bong.) seedlings grown in perlite-filled pots in a climate controlled growth room were studied. Nodulated seedlings were subjected to 12 different nutrient solution combinations of nitrogen and phosphorus and...

The effect of preplant nitrogen fertilization and soil temperature on biological nitrogen fixation and yield of alfalfa (Medicago sativa L.)

Creator:: Shuler, Philip E.
Abstract:: The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa...

Nitrogen and environmental factors influence bark storage protein gene expression in poplar

Creator:: Banados, Maria Pilar
Abstract:: In poplar (Populus spp.) a 32-kilodalton bark storage protein (BSP) accumulates during the fall and winter, and is thought to be a major storage form of overwintering nitrogen. BSP is induced by short-day (SD) photoperiod, and under natural conditions BSP accumulation coincides with the induction of dormancy. Because BSP accumulates...
