Abstract

The experiment was conducted in The Jute Research Regional Station, Kishoreganj during 2010-2011 to find out the effect of plant age for cuttings and plant spacing on growth and seed yield of olitorius jute. The experiment consisted of six plant age for cutting such as 80, 90, 100, 110, 120 and 130 days; and three planting spacings such as 20cm x 10cm, 30cm x10cm and 40cm x10cm. Randomized complete block design was used for the experiment with 3.0 m x 3.0 m plot size and four replications. The result showed that the highest population density m-2 (18.00), plant height (1.75 cm), and seed yield (1.09 t/ha) was obtained with 100 days old cutting age planted using 20cm x 10cm. The highest seed yield was attributed to to the highest number of plant population and the lowest number of mortality percent per unit area.
