Abstract: A field experiment was conducted at Central Agricultural University, Imphal, Manipur during 2010 and 2011 to study the effect of spacing on the growth and yield of Hedychium spicatum, a valuable medicinal plant in temperate regions. Treatments comprised of four plant spacing: 30 × 20 cm, 30 × 30 cm, 30 × 40 cm and 40 × 40cm. Results showed that values on growth of H.spicatum were found to be highest in widest spacing of 40 × 40 cm (14.16 t ha-1). Yield of the crop was higher even in 30 × 40cm spacing (13.46 t ha-1) than the closer spaced distance 30 × 20 cm and 30 × 30 cm which gave 10.39 and 12.54 t ha-1 respectively. Though the number of rhizomes per unit area in closest spacing, 30 × 20 cm (32.61) outnumbered that of rhizomes per unit area in widest spacing, 40 × 40 cm (14.33), yield was observed to be highest in 40 × 40cm spacing which may be due to highest number of tillers plant-1 (3.41) and fresh weight of rhizomes plant-1 (109.61g) compared to lowest number of tillers plant-1 (2.54) and fresh weight of rhizomes plant-1 (68.08 g) in 30 × 20 cm spacing.
