Asparagus Response to Water and Nitrogen

Abstract

The relationships of asparagus yields to varying levels of water and nitrogen were determined. Maxinuem yields of 345, 560 and 300 crates/acre were produced for asparagus crowns that were 3, 4 and 5 years old, respectively. A total seasonal water depletion rate of 98 inches was calculated for the fern growing season. Optimum nitrogen applications were estimated at approximately 350 -400 lb/ac.
