Purpose: The purpose of this paper is to investigate the germination behaviour of Guizotia abyssinica (L.f.) Cass. (Asteraceae) commonly known as Ramtil (H) and Niger (E). It is an important oil-yielding plant, known for its medicinal as well as commercial value and special treatments.
Design/methodology/approach: Various phyto-hormones and NPK were used to determine the germination profile of the species.
Findings: The seed germination increased after pre-sowing treatments and a remarkable increase in germination percentage was recorded. The findings reveal that maximum germination percentage (90%) was noticed in phyto-hormones and NPK treatments; germination percentage was comparatively poor in dark conditions and sand.
Originality/value: The species is endangered and will disappear from the Indian sub-continent very soon, therefore the need to increase the germination profile and to increase the productivity of the plant is a great challenge.
