The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural
University, Dhaka. Bangladesh during the period from November 2010 to May 2011
to study integrated nutrient management for hybrid boro rice. The experimental
treatments included T1 = No chemical fertilizer, no organic manure (Control),
T2=100% recommended N(120 kg nitrogen / ha) + recommended P.K.S: 13=80 kg N
from urea + 40 kg N substituted by vermicompost

from urea + 80 kg N substituted by vermicompost + recommended P,K,S;
from urea ± 80 kg N substituted by cow dung + recommended P,K,S; T9 80 kg N

of vermicompost and cow dung + recommended P,K,S; T4O kg N from urea + 80
kg N substituted by equal portion of vermicompost and cow dung + recommended
N substituted by equal portion of vermicompost and cow dung -
recommended P.K.S. The experiment was laid out in Randomized Complete Block
Design (RCBD) with three replications. Results showed that different nutrient
management significantly differed in all growth and yield contributing characters.
The maximum grain yield (7.16 1 had
) was produced from T

(5.55

was produced
from control treatment. The maximum biological yield (16.73 t haj was produced
from T10
(60 kg N from urea + 60 kg N substituted by equal portion of vermicompost
and cow dung + recommended P,K,S) treatment. The maximum harvest index
(48.83%) was produced from control treatment. The minimum harvest index (42.19
%) was produced from T
10 (60 kg N from urea 60 kg N substituted by equal portion
of vermicompost and cow dung + recommended P.K.S) treatment. The higher grain
yield was attributed mainly to the number of effective tillers hilr', filled grains
panicl&' and 1000-grain weight. The highest N, P. K and S concentration in grain
was recorded from 60 kg N from urea + 60 kg N substituted by equal portion of
vermicompost and cow dung + recommended P,K,S treatment. The highest N, P. K
and S concentration in straw was recorded from 60 kg N from urea + 60 kg N
substituted by equal portion of vermicompost and cow dung + recommended P,K,S treatment.
