Growth rate and phosphorus uptake of wheat (Triticum aestivum VILL., Host) as a function of soil water suction and soil temperature

Creator:: Fazilat, Mohammad
Abstract:: The effect of soil temperature and soil water suction on the rate of phosphorus uptake and growth rate of wheat (Triticum aestivum VILL. , Host) was studied. Plants were grown in perlite slabs separated from an osmotic solution by a semi-permeable membrane. Measurements were made at temperatures of 10.0, 18.3,...

Nitrogen accumulation during the growing season by russett Burbank potatoes (Solanum tuberosum)

Creator:: Kanji, Badrudin Jamal
Abstract:: Nitrogen is one of the most important nutrients influencing potato yields. The potential for environmental pollution from N is also greater than for other nutrients added as fertilizer because excessive amounts applied are subject to leaching into drainage water. The purpose of this study was to improve N fertilizer recommendations...

Liming requirement of selected Willamette Valley soils

Creator:: Peterson, Paul William
Abstract:: There are two major problems associated with soil acidity and lime response investigations: A. Determining how much lime (100% "available" CaCO₃ equivalent) is required to raise a soil pH (or degree of acidity) from its existing level to a specified level - presumably where need for lime is eliminated. B....

The potassium status of Eastern and Central Oregon soils

Creator:: Abuzkhar, Ahmed Ali
Abstract:: The potassium status of selected soils from central and eastern Oregon, that have shown a wide range in response from potassium was investigated. The silt and clay minerals were identified using X-ray crystallography. The potassium extracted by water, NH₄OAc, and HNO₃ was evaluated on the total soil and on the...

Varietal differences in response of winter wheat varieties to nitrogen fertilizer and environment

Creator:: Ambler, John Richard
Abstract:: The purpose of this study was to evaluate differences between winter wheat varieties in response to nitrogen fertilizer. Seven nitrogen fertilizer rate x variety factorial experiments were conducted in several environments. Dry matter and nitrogen yields at boot, soft dough, and harvest and grain yield components were measured. The yield...
