A Simple Model To Predict Optimal Harvest Time Of Alfalfa Using Near Infrared Reflectance Spectroscopy, Environmental, Morphological, And Growth Parameters, Jody A. Gale
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Knowledge of relationships between nutrient levels, yield, maturity, and environmental influences on alfalfa (Medicago sativa L.) are necessary to estimate when to harvest alfalfa to maximize quality and yield. Objectives were to document the change in nutrient content, yield, and growth stage of alfalfa grown in Utah as it matures and to develop a simple model to predict optimal harvest date. The study involved three locations in major alfalfa producing regions in Utah. Samples were collected from three commonly grown alfalfa varieties between 26 April and 26 September in 1987. Maximum and minimum levels of crude protein (CP) observed were …
