Determining A Crop Production Function For Corn As Influenced By Irrigation And Salinity Levels, Timothy E. Sullivan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Production functions were generated for dry matter and grain yields of corn, A continuous variable plot design replicated four times was established in the spring of 1974 in Vernal, Utah. Each replication included ten salt treatments and twenty irrigation levels. The salt treatments resulted in an average root zone salinity ranging from 2 . 7 to 14.9 mmhos/cm. Irrigation levels ranged from 4.2 to 45.0cm of water applied. Dry matter (Kg/ha) yield showed an 83 percent reduction over the range of salt applied and a 52 percent reduction over the range of water applied. Grain yield declined 96 and 64 …
