Abstract:
A pot experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka
during the period from October, 2019 to April 2020, to study the response of
sweet pepper varieties to different levels of chitosan raw material powder. The
experiment was consisted of two factors, and followed Completely Random
Design (CRD) with seven replications. Factor A: Sweet pepper varieties viz (2):
V

: BARI Sweet pepper 1 and V
: BARI Sweet pepper 2; and Factor B: Application
of different levels of chitosan raw material powder viz (4); C

fruit yield plant

(139.18 g) was recorded in V
(BARI sweet pepper 2)
treatment. Application of 1 % chitosan raw material powder (C

) played a major
role for plant growth and yield of sweet peppers and it's also influenced soil
characteristics. The highest number of fruits plant

(3.07), fruit yield plant
(157.29 g), soil pH (6.5), soil total nitrogen content (0.12 %), organic carbon (0.76
%) and organic matter (1.31 %) were recorded in C
treatment. Increasing chitosan
levels influenced plant growth and development and the highest fruit yield plant

pot
-1
(188.43 g) was recorded in BARI sweet pepper 2 cultivation along with
application of 1 % chitosan raw material powder (V

C
). From these results it can
be concluded that yield and yield contributing characters of sweet peppers and
some chemical properties of soil were improved due to the application of chitosan
raw material powder. Taken together, our results suggest that chitosan raw
material powder have some positive effect on slow releasing nitrogen
supplementation, soil organic carbon and soil pH which influenced plant growth,
development and yield.
