Energy efficiency of forage maize production in an Atlantic Canadian environment.
Abstract
5 forage maize cv. were grown at a site in Stewiacke East, Nova Scotia. DM production rates and environmental conditions were measured during June-Sept. Above-ground DM yield averaged 13.4 t/ha for a 112-day growing season, representing 1.04% of the total solar radiation received during the season. Observed growth rates and production efficiencies of the 5 cv. were in good agreement with predictions of a theoretical model of maize productivity.
