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...

Abstract:: The effect of moisture stress and nutrients on the rate of growth of wheat (Triticum aestivum L. Var. Gaines) seedlings was studied. A special apparatus in which the moisture stress of several perlite cells could be maintained constant by osmotic solutions was used. Predetermined amounts of nitrogen were added to...

Creator:: Christensen, Neil Walter, 1944-
Abstract:: The phenomena known as "phosphorus-induced zinc deficiencies" are poorly understood. Conclusions drawn from research efforts designed to identify the mechanism of the phosphorus-zinc interaction are, in many cases, incompatible. Similarities in the data from a number of literature reports of "phosphorus-induced zinc deficiencies" have led to the development of the...

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,...
