Abstract

Feed planning enables ranchers to use feed resources efficiently and increase profits. Feed budgeting requires estimates of expected daily growth rate (DGR) of pasture. The purpose of this study was to estimate DGR and determine if weather variables and herbage mass could be used to predict DGR for an irrigated pasture dominated by tall fescue (Festuca arundinacea Schreb.) and strawberry clover (Trifolium fragiferum L.). A single-probe capacitance meter was used to estimate herbage mass over 2 yr. Daily growth rate was calculated during the rest periods on 16 rotationally-grazed paddocks. Maximum and minimum daily air and soil temperature, and solar irradiance were recorded by a California Irrigation Management Information System (CIMIS) weather station located within the pasture []
