Abstract:
The present study was conducted in the experimental field of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during
November 2017 to March 2018, to determine the contribution of tillers on rice
seed yield as affected by variety and seedling age in Boro season. The experiment
was laid out in randomized complete block design (RCBD) with 3 replications.
The experiment included two varieties of Boro rice (V

= BRRI dhan28 & V
=
BRRI dhan29) and 5 treatments (T

= 10 days old seedlings, T

seedlings, T

= 30 days old seedlings, T

= 45 days old seedlings, T
= 60 days old
seedlings) along with each of 3 replications. The results revealed that higher
values of all the yield attributes were maximum under T

(30 days old seedling) in both the varieties viz. BRRI dhan28 and
BRRI dhan29 where a clear dominancy of BRRI dhan29 over BRRI dhan28 on
every parameter. Transplantation of 15 days old seedlings (T
) produced
significantly higher grain yield. In variety and seedling age combination, most of
the yield parameters exhibit the highest values V

(BRRI dhan29 x 30 days old
seedlings). The results revealed that transplantation of seedlings (above 15-30 and
above 40 days old) and younger seedlings below 15 days old reduced the grain
yield consistent
