    PERFORMANCE OF ADVANCE LINES OF AROMATIC RICE UNDER DIFFERENT TRANSPLANTINC DATES
    (DEPARTMENT OF AGRONOMY, 2007) AHMED, IFTEKHAR
    A field experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural University (SAU), Dhaka during the ,lma,; season in July to November 2005, with a view to study the perlbrmance of newly developed Suvash promising lines under different transplanting date along with one modern variety. The experiment consist two levels of treatments viz. A: Four transplanting date: 15 July. 1 August. 15 August and 1 September. 13: Four promising lines/ variety: Subashi, Suhash2. Subash5. and inbred variety BRRI dhan38. The experiment was laid out in split plot design with three replications. Experimental result showed that transplanting dates and variety individually had significant elket on the agronornic parameters like plant height. paniele length, total tiller in non-effective tillers nf 2 . effective tillers n12 . total spikelet panicle 1 . filled grains panicl&'. spikalet sterility (%). grain yield (1 ha). straw yield (t ha1 ) and biological yield (t ha'). The result revealed that I August transplanting gave the highest grain yield (4.03 t ha1 ) which was at per with 15 July transplanting (3.88 t haj. Among the varieties Subashl gave the highest yield (3.95 t ha d ) but that was at per with those of Suvash2 (3.81 t had) and inbreed variety I3RRI dhan38 (3.72 t ha').The combined effect of date of transplanting and variety had also significant effect on yield and yield characters. Subash I and }3RRI dhan38 planted on 1 August showed highest yield attaining good yield contributing characters.
