Abstract:
A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka-
1207, to evaluate combined effect of biochar and phosphorus on growth and yield of
wheat under different irrigation regime during November 2019 to March 2020. The
experiment was laid out in two factor split plot design with three replications. Irrigation
regime under main factor were I

) and harvest index (47.75%) were obtained from I
stage and 5 ton biochar +15 kg phosphorus ha
is recommendable for improved wheat production.
