There were significant differences in plant
height between treatments (Table 2). The
tallest plants were produced by ginger
cultivated in 100% coir dust with an average
height of 123 ± 23 cm and the lowest were
those cultivated in mixture of 30% coir
dust and 70% burnt paddy husks (average
height 105 ± 8 cm). Treatment containing
100% coir dust produced the tallest plants
compared to burnt paddy husks and mixtures
of both substrates. This could be due to the
higher porosity of coir dust compared to
