An experiment was conducted during 1998-99 to study the effect of different spacing (50 cm x 20 cm, 50 x 30 cm and 50 x 40 cm) and K 2 O rate (0, 40, 75, 120 and 150 Kg haG 1 ) on the growth, dry matter, production and yield of turmeric (Curcuma longa L.). Close spacing produced the tallest plants (87.89 cm), medium spacing produced the plants (87.89 cm), medium spacing produced the plants with the highest finger breadth (6.95 cm) and primary finger per plant (2.71) while wide spacing produced

... ith the highest number of tillers per hill (3.42), leaves per plant (8.56), total dry weight per plant (53.79 g) and highest yield per plant (189.35 g). But total yield (t haG 1 ) was highest with close spacing. Almost all of the characters studied showed increasing trend with increasing rate of potassium and the highest yield (15.4 t haG 1 ) was obtained with 120 Kg haG 1 K 2 O. The interaction effect of spacing and potassium exhibited insignificant variation in most of the characters.
