ABSTRACT

The study was conducted to determine the effect of spacing on morpho-physiological response
of different T. Aman rice cultivars under coastal high land ecosystem. Assessment was done on
plant height (cm), total tillers hill-1, effective and non-effective tillers hill-1, panicle length (cm),
grains panicle-1, unfilled spikelets panicle-1, total spikelets panicle-1, 1000-grain weight (g), grain
yield (t ha-1), straw yield (t ha-1) and harvest index of the selected rice cultivars. Interaction effect
revealed that the variety BRRI dhan44 produced the highest grain yield (4.83 t ha-1) at the
spacing of 15 cm×15 cm. The Variety BRRI dhan44 at low spacing (15 cm×15 cm) may be
followed to get high yield in coastal high land ecosystem of Bangladesh.
