Models of a four-species annual weed community : growth, competition, and community dynamics

Creator:: Roush, Mary Lynn
Abstract:: Models of weed communities aid in the development of weed management strategies and elucidate the processes and mechanisms that regulate plant populations and communities. A conceptual weed community model was developed to organize key regulatory life-history processes. Specific investigations focused on the processes of plant growth and competition, and relationships...

Corn (Zea mays L.) yields as influenced by nitrogen, row spacing and intercropped ryegrass (Lolium multiflorum)

Creator:: Wivutvongvana, Paibool
Abstract:: Two field corn experiments were conducted on a Woodburn silt loam soil near Corvallis, Oregon, in 1972-1973 to investigate the effects of certain soil management practices on the yield and performance of corn (Zea mays L.). Experiment I involved variables that included three corn row spacings (76, 114, and 152...

Effect of N, Mn, and Cu treatments on nutrient uptake by barley, oats, wheat, and triticale

Creator:: Kalayci, Mufit
Abstract:: Experiments were established on a Warden soil on Lower Klamath Lake area to evaluate the effect of Mn and Cu, and Band applications of ammonium sulfate on the uptake of micronutrients and response from Mn and Cu applied for the production of small grain crops. Band application of ammonium sulfate...

Developmental anatomy of Phaseolus vulgaris L. as influenced by temperature

Creator:: Wivutvongvana, Manee
Abstract:: Bush snap beans (Phaseolus vulgaris L.) cvs 'G5O' (Gallatin 50) and 'OSU58' (Oregon 58) were used for anatomical and morphological studies of their responses to three levels of temperature. The plants were grown in a controlled chamber under a 16-hour photoperiod at 60°/50°, 70°/60° and 80°/70°F (day/night temperature), respectively. The...

Effects of plant population on plant characteristics and yield of bush snap beans

Creator:: Hatch, Duane Leroy
Abstract:: 'Tendercrop' and 'OSU 949' green snap beans were grown at populations varying from 77,000 to 392,000 plants per acre with two row spacings and six square arrangements ranging from 4 x 4 to 9 x 9 inches. Maximum yield of 10.1 tons per acre (32 percent sieve size 4 and...

The effects of plant population and nitrogen on sweet corn yields

Creator:: Moss, Joe Dick
Abstract:: The response of sweet corn (Zea mays L. var. rugosa cultivar Jubilee) to 12 populations and four nitrogen rates was studied in a field experiment. Populations ranged from 43, 904 to 329,800 plants/ha with nitrogen levels ranging from 0 to 224 Kg/ha. A systematic spacing design was used. Plant height,...

Intensively managed irrigated hard red winter wheat production

Creator:: Oregon State University. Agricultural Experiment Station, Pumphrey, F. V. (Floyd Vance), Kolding, Mathias F., and Broich, Steven L.
Abstract:: Hard red winter wheat will produce grain yields comparable to soft white winter wheat in intensively managed irrigated fields. Planting should be early enough in the fall for the plants to initiate tillers and crown roots before winter dormancy. Seeding about 80 pounds of seed per acre will provide an...
