The influence of different forms and concentrations of nitrogen on total nonstructural carbohydrate allocation and growth in Digitaria eriantha

Abstract

Digitaria eriantha plants were grown under controlled conditions for a period of three months, during which time they were supplied with the following forms and concentrations of nitrogen: 50 mg/1 NO₃ ⁻‐N, 200 mg/1 NO₃ ⁻‐N, 200 mg/1 NH₄ ⁺‐N and a combined form containing both NO₃ ⁻‐N and NH₄ ⁺‐N with a nitrogen concentration of 200 mg/1. Control plants received no nitrogen.
