Abstract
The developmental pattern of jicama (Pachyrhizus erosus (L.) Urban) wa s studied by sampling plants aged 20 to 36 weeks at weekly intervals. There was an increase in all characteristics of foliage: fresh and dry weight, number of leaves per plant, main stem length, number of leave s, nodes and internodes of the main stem; and in all root characterist ics: fresh and dry weight, diameter and length. The chemical analysis was determined for roots at different plant ages. The range values for dry matter were 16.19-22.28%, protein 1.11-1.62%, fat 0.553-0.867%, c rude fiber 0.3048-0.3943%, and ash 0.669-1.089%. The chemical constitu ents fluctuated with age but without specific trends. These values are considered the first record of roots produced by plants grown in Mexi co.
