Abstract
A pot experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka from
November 2021 to March 2022 in Rabi season to study the effect of different composted
plant species on water stress effect of wheat. The experiment consisted of two factors and
followed a Completely Random Design (CRD) with three replications. Factor A.
Different drought stress condition (2) viz I
0
= Drought imposition and I
= Irrigation; and
Factor B. Different composted plant materials (17) viz T

= Rice straw (Oryza sativa). The experimental result revealed that grain yield
decreased due to drought stress conditions, and the lowest grain yield plant
(3.12 g) was
observed in drought imposition (I
) treatment. In the case of composted plant materials,
the highest mean effective tillers plant

(3.73), spike length (8.22 cm), grains spike
(43.00), 1000-grain weight (41.10 g) and grain yield plant
-1
(5.60 g) were observed in
both stress and non-stress condition in T
(Rice straw) treatment. In the case of
interaction treatments, cultivation of wheat with irrigated condition (I
17
) along with rice
straw composted materials (T

) affected plant growth and yield-contributing
characteristics, leading to the maximum grain yield plant
-1
(6.02 g) than compared to
other interaction treatments. However, I

(5.86 g), I

(5.84 g), and I
(5.74 g)
interaction treatment showed statistically similar grain yield plant

. Therefore, it may
suggested that wheat cultivation with proper irrigation, as well as soil incorporated with
rice straw, wheat straw, sunflower, and khasari composted materials, would influence
plant growth, retain soil moisture and nutrient content and increase its ability to enhance
better wheat yield production.
