Abstract:
A pot experiment was carried out in the experimental site of Bangladesh Institute of Nuclear Agriculture.
Mymensingh from June to November. 2002 with a view to study the growth and yield performances of two
modem varieties of transplant aman rice as affected by number of seedlings hiW' and water regimes. Variety.
number of seedlings nnr', water regimes and their interactions exerted significant influence on almost all the
crop characters. At all the growth stages. the maximum values of total tillers hill". leaf. stem. root. shoot.
and total dry matter hill', leaf area index were found in BINA dhan 4x4 seedlings hill" x intermittent
irrigation. whereas the minimum values of those parameters were in BRRI dhan 39x 2 seedlings hill" x 2527
ern continuous stagnant water. The highest total dry matter (88.09 g) and grain yield pot' (31.25 g) were
achieved in the treatment combination of BINA dhan 4 with 4 seedlings hiW' and intermittent irrigation.
