Effect of nitrogen rates, row spacings and population densities on yield and ear characteristics of sweet corn

Creator:: Yassen, Abdulameir Ali
Abstract:: The response of sweet corn Zea mays L. var. rugosa (cultivar 'Jubilee') to row spacing, nitrogen and population density at two planting dates was studied in a field experiment at the OSU Vegetable Research Farm in 1984. Variables included two row spacings, 75 cm and 90 cm, three nitrogen rates,...

The effect of row spacing, rate and date of planting on yield and yield components of four winter wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Nadjib, Benacef
Abstract:: Four winter wheat cultivars, Bezostaya, Maris-Hobbit, Roussalka and Stephens, selected on the basis of the diversity of their pedigree and phenotype, were planted at Hyslop Experiment Station near Corvallis in Western Oregon to study their performance at three different row spacings (10, 16 and 24 cm), three seeding rates (100,...

Influence of irrigation and plant population on yield parameters, flower and pod abscission, and photosynthate distribution in snap beans, Phaseolus vulgaris L.

Creator:: Mauk, Craighton Stiles
Abstract:: During 2 seasons effects of high and low irrigation (water applied at -0.6 and -2.5 bars soil water potential, respectively) and density were evaluated on yield parameters and flower/pod development at mainstem nodes 2 and 6 (terminal) of 'Oregon 1604', a determinate snap bean. High and low plant densities were...

Effect of Soil Acidity and Nitrogen on Yield and Elemental Concentration of Bush Bean, Carrot, and Lettuce

Creator:: Hemphill, Delbert D. Jr and Jackson, T. L. (Thomas Lloyd), 1922-
Abstract:: Bush beans (Phaseolus vulgaris L.), carrots (Daucus carota L.), and lettuce (Lactuca sativa L.) were grown for 3 years on soils amended with S or lime and N fertilizer. Yields of all crops increased with lime application but response to N varied among crops and years. Lettuce head weight tended...

Effects of irrigation scheduling, using remotely sensed canopy-air temperature differentials, on water relations, yield, and quality of snap beans (Phaseolus vulgaris L.)

Creator:: Bonanno, A. Richard
Abstract:: Field experiments were conducted in 1981 and 1982 to develop a method for using remotely measured leaf canopy-air temperature differences (stress-degree-days (SDD)) to schedule irrigations and to evaluate the effects of differential irrigation on snap bean cultivars, 'Oregon 1604' and 'Galamor'. Effects on soil water potential (SWP), leaf water potential...

Effects of planting bush beans (Phaseolus vulgaris L.) in single or double rows

Creator:: Mhaka, Amon Gwaziva
Abstract:: A comparison was made between double rows 15 cm apart on 76 cm centers and single rows 76 cm apart of 'Oregon 91G' bush green beans at the same planting densities in three experiments in 1986 and 1987. There was a significant increase in yields of pods from double rows...

Irrigation water and plant density effects on the epidemiology of aerial stem rot of potatoes

Creator:: Cappaert, Marlys R.
Abstract:: Field plots of cv. Russet Burbank potatoes from a single seedlot were established at four sites over two seasons (1985-86) in two locations in Oregon to determine the role of water-borne inoculum of Erwinia carotovora in plant infection. One site at each location was irrigated from a surface-water source and...

Table Beet Yield and Boron Deficiency as Influenced by Lime, Nitrogen, and Boron

Creator:: Hemphill, Delbert D. Jr, Weber, Michael S., and Jackson, T. L. (Thomas Lloyd), 1922-
Abstract:: 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...

Nitrogen fertilizer rate and application timing effects on growth and seed-oil yield of meadowfoam

Creator:: McGahuey, Michael L.
Abstract:: Meadowfoam has been identified as a potential oilseed crop for production on poorly drained soils in areas with cool, moist winters. The effects of N fertilizer on meadowfoam (Limnanthes alba Benth.) have been studied in Oregon and Maryland, but the results have not been consistent with respect to the effects...
