Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett

Soil Science News and Views

An experiment was conducted for a period of three years, 1982, 1983 and 1984, in order to evaluate the effects of soil water stress and irrigation on growth, yield and quality of burley tobacco at Spindletop Farm, Lexington. The variety KY 21 was grown all three years. Three treatments were used in the experiment: (1) check, rainfall only, not irrigated, (2) well watered, rainfall plus supplemental irrigation, and (3) water stressed beginning 50 days after transplanting. The soil of treatment 3 was covered with black plastic to prevent rainfall from entering the soil.

The Behavior Of Soluble Salt In Sharkey Clay- Ii, J. T. Gilmour, R. E. Baser, H. D. Scott, J. A. Ferguson

Technical Reports

Soluble salts have been shown to accumulate in Arkansas soils in sufficient quantities to impair crop plant growth. The major objective of this study was to describe the behavior of soluble chloride salt over long time periods in Sharkey clay - a major Mississippi Delta soil. Prior to flooding rice, leaching of chloride in response to rainfall was observed. The inclusion of a sandy subsoil layer reduced this effect presumably by limiting downward movement of water under unsaturated conditions. No lateral movement of the chloride salt was found during the period prior to flooding. Removal of soluble chloride salts from …

Boron Composition Of Alfalfa In Utah As Related To Soils And Irrigation Waters, Robert N. Radtke Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Eighteen field plots at 15 locations were selected throughout the state to evaluate the status of the boron content in irrigation waters, soils, and alfalfa (Medicago sativa) plant tissue under irrigated conditions.

No boron deficiency symptoms were observed in any of the alfalfa plants at any of these locations, nor were any of the plant tissue boron levels inadequate. Only two locations were found in which the alfalfa plants exibited toxicity symptoms. These locations were along the Indian and Antelope Creeks in Duchesne County which contain high boron levels in the water. All the alfalfa and soil tested …
