Alfalfa Production As Related To Irrigation Scheduling: An Economic Perspective, Craig L. Israelsen
Alfalfa Production As Related To Irrigation Scheduling: An Economic Perspective, Craig L. Israelsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study analyzed the economics of irrigation scheduling for alfalfa hay in the Cache Valley, Utah area. Yield, evapotranspiration (ET) and irrigation drainage loss, along with the costs and returns per acre attributable to irrigation scheduling, were simulated through the use of a computerized plant growth model. The model created yearly "irrigation schedules" for alfalfa hay based on actual climatic, soil and plant characteristic data from the Utah State University Greenville Experiment Station. The model calculated the irrigation schedules based on a soil-water balance equation which never allowed the available soil water to go below the crop stress point.
The …
Estimating Agricultural Production Functions From Experimental Data For Different Crops In Relation To Irrigation, Fertilization And Soil Management In Northern Utah, Subramaniuam Swami Nathan
Estimating Agricultural Production Functions From Experimental Data For Different Crops In Relation To Irrigation, Fertilization And Soil Management In Northern Utah, Subramaniuam Swami Nathan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Estimates of agricultural production functions from experimental data for four different crops in relation to six variable inputs are calculated by this study. There are four basic sections in the study. The first section covers the review of production function concepts and the procedures and problems that specifically pertain to this study. Also the importance of joint economic-agronomic research efforts, methodologies and applications of agricultural production functions are cited.
The second section includes the presentation data and postulated functional relationships in estimating production functions. Model building programs are used in developing three dimensional figures, which aid in the selection of …
Estimated Supply Response Of Sugar Beet Production To Changes In Profitableness, Box Elder And Cache Counties, Utah, 1967, Brent W. Spaulding
Estimated Supply Response Of Sugar Beet Production To Changes In Profitableness, Box Elder And Cache Counties, Utah, 1967, Brent W. Spaulding
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The relative profitability of sugar beets and competitive crops were studied in Box Elder and Cache counties, Utah.
Profitability ratios based on enterprise budget data and resource use requirements were used as a basis for comparison. Sugar beets was found to be more profitable than competing crops in returns per acre, in returns to water used and in returns to fixed investment and management. However, sugar beets was found to be less profitable than certain other crops in returns to operating capital and returns to labor. Also, on land rated low in productivity sugar beets was found to be less …
