Tuberose (Polianthes tuberosa L.) was grown on eight different substrate combinations in 6” plastic pots for two consecutive years at ICAR-IIHR, Bengaluru. The influence of the substrate on vegetative growth, spike production and quality were evaluated. Arka Fermented Cocopeat was used as the main component of all the substrates with different amendments. These were compared with the conventional soil based media. The substrate combination of Arka fermented cocopeat (AFC) + soil + sand + FYM (1:1:1:1 v/v) was found to be most suitable media for pot plant production of tuberose var. Arka Sugandhi with maximum number of spikes per plant () and longevity of spikes on the plant ( days). | Standardization of substrate composition for pot plant production of tuberose var. Arka Sugandhi
