A pot experiment was conducted under the net house of Sher-e-Bangla Agricultural
University (SAU), Dhaka, Bangladesh, during December 2020 to May 2021, to study
on yield performance of a rice variety (BRRI dhan84) as influenced by the effects of
seed priming with salicylic acid (SA) and using organic material (Shrimp Shell
Powder, SSPd) in the seedbed. Fourteen (14inches) size plastic pots were used in the
experiment having height (10.5inches) and diameter (9.5inches). The pots were filled
with 10 kg SAU field moist soils having the texture silty clay loam soil. The
experiment was laid out in a Completely Randomized Design (CRD) having six
treatments (T
1
= 0 μM Salicylic Acid + 0% Shrimp Shell Powder, T
= 0 μM Salicylic
Acid + 0.25% Shrimp Shell Powder, T
3
2
= 0 μM Salicylic Acid + 0.5% Shrimp Shell
Powder, T
4
= 50 μM Salicylic Acid + 0% Shrimp Shell Powder, T
= 50 μM Salicylic
Acid + 0.25 % Shrimp Shell Powder, T
6
5
= 50 μM Salicylic Acid + 0.5% Shrimp Shell
Powder) with twenty four (24) replications. A significant variation was observed in
the germination (%), seedlings height, biomass production, seedling strength and
chemical properties of the seedbed soils due to the seed priming with SA and
application of Shrimp Shell Powder in the seedbed. The maximum germination
(79%), seedlings height (24.65cm), seedling fresh weight (593.29mg), seedling oven
dry weight (396.14mg), seedling strength (18.08mg cm
−1
), grain yield sundry weight
(66.35g pot
−1
), grain yield oven dry weight (58.17g pot
−1
) and straw yield
(70.25g pot
−1
) were observed in the treatment T
. Otherwise, the minimum
germination (61%), seedlings height (19.52cm), seedling fresh weight (239.67mg),
seedling oven dry weight (144.84mg), seedling strength (7.42mg cm
6
), grain yield
sundry weight (49.59g pot
−1
), grain yield oven dry weight (43.61 g pot
) and straw
weight (51.12g pot
−1
) were recorded in the treatment T
(control). Whereas, the
maximum level of OC (0.78%), OM (1.34%), pH (6.4), available Phosphorus (39.34
ppm) and available Sulphur (30.36ppm) were recorded in the treatment T
1
. Otherwise,
the minimum level of OC (0.64%), OM (1.1%), pH (6.3), available Phosphorus
(17.69ppm) and available Sulphur (17.22ppm) were recorded in the treatment T
(control). Shrimp Shell Powder increased the level of organic matter in a dose
dependent manner. Quality of the rice seedlings were improved due to the application
of the organic matter in a dose dependent manner and the treatment T
(50μM
Salicylic Acid + 0.5 % Shrimp Shell Powder) was the more effective than other
treatments. Most of the morphological, yield attributes and grain yield were increased
with increasing the dose of Shrimp Shell Powder. Maximum grain yield was observed
in T
6
treatment followed by T
5
,T
4
,T
3
, T
2
and T
(control). So overall result indicated
that application of shrimp shell powder in soil has significant impact on growth and
yield of BRRI dhan84 and some on chemical properties of soil.

MOLLIK, MD. ASMAUL HAQUE
An experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka-1207
during the period from November 2021 to May 2022 to examine the effect of organic and
inorganic fertilizer application on rice production (BRRI dhan28). The experiment
consisted of eight treatments viz. T

(control; no organic or inorganic fertilizer), T
2
(100%
RDCF; N

), T
3
(only poultry manure; 100% N), T
4
(only
vermicompost; 100% N), T
5
(50% RDCF; 50% NPKSZn kg ha
-1
+ 50% poultry
manure),T
6
(50% RDCF; 50% NPKSZn kg ha
-1
+ 50% vermicompost), T
7
(25% RDCF;
25% NPKSZn kg ha
-1
+ 75% poultry manure) and T
8
(25% RDCF; 25% NPKSZn kg ha
+ 75% vermicompost). The experiment was laid out in a Randomized Complete Block
Design (RCBD) with three replications. A significant variation was observed among the
treatments due to different levels of organic and inorganic nutrient sources. The treatment
T
2
(100% RDCF; N

) exposed the highest plant height at (92.12
cm) and the treatment T
6
(50% RDCF; 50% NPKSZn kg ha
-1
+ 50% vermicompost)
showed the highest number of tillers hill
-1
(17.24) whereas control treatment T
1
(no
organic or inorganic fertilizer) showed the minimum results in both plant height and
tillers hill
-1
. Again, the treatment T
6
(50% RDCF; 50% NPKSZn kg ha
+ 50%
vermicompost) produced the highest number of effective tillers hill
-1
(15.87), flag leaf
length (21.64 cm), number of filled grains panicle
-1
(129.20), panicle length (23.52 cm),
grain yield (5.32 t ha
-1
), straw yield (6.14 t ha
-1
), biological yield (11.46 t ha
) and
harvest index (46.42%) followed by T
5
(50% RDCF; 50% NPKSZn kg ha
+ 50%
poultry manure) whereas the control treatment T
1
(no organic or inorganic fertilizer)
showed the lowest results in all the parameters. In case of post-harvest soil, different
treatments of organic and inorganic fertilizers and their combinations showed no
significant variation on pH and organic carbon content but available N, available P,
exchangeable K, available S and available Zn content of postharvest soil affected
significantly. The treatment T
6
(50% RDCF; 50% NPKSZn kg ha
+ 50%
vermicompost) showed highest available N (1.52%), available P (24.52 ppm),
exchangeable K (1.216 meq/100g soil), available S (26.44 ppm) and available Zn (0.174
ppm) whereas the lowest available P and available S content was obtained from control
treatment T
1
(no organic or inorganic fertilizer). So, the treatment T
6
(50% RDCF; 50%
NPKSZn kg ha
-1
+ 50% vermicompost) can be considered as a potential onefor higher
rice production (BRRI dhan28).

SUNY, NUSHRAT JAHAN
The experiment was conducted at the research field of Sher-e-Bangla Agricultural
University, Dhaka, during the Rabi season from November, 2021 to April, 2022 to
investigate the effect of sulphur (S) and zinc (Zn) fertilizer on green chili production
(cv. BARI Morich 4). The experiment consisted of two factors, viz., Factor A: 3 levels
of Sulphur (S
0
: 0 kg ha
-1
, S
1
: 20 kg ha
-1
, S
2
: 30 kg ha
ii
-1
) and Factor B: three levels of
zinc (Zn
0
: 0 kg ha
-1
, Zn
1
: 2 kg ha
-1
and Zn
2
: 4 kg ha
-1
). Two factor experiments with
Randomized Complete Block Design was followed with 9 treatment combination and
replicated three times. Vegetative growth, yield contributing characters and yield were
measured during the experiment. In case of S treatment, the tallest plant (66.12 cm),
number of leaves plant
-1
(96.13), number of branches plant
-1
(15.50) were observed at
80 DAT and the highest number of fruits plant
-1
(104.57), flowers plant
(111.18), fruit
length (7.10 cm), fruit diameter (0.56 cm), individual fruit weight (1.73 g), average fruit
weight plant
-1
(177.27 g), fruit yield ha
-1
(28.21 t) were obtained from S
1
treatment. In
case of Zn treatment, the tallest plant (66.06 cm), number of leaves plant
(92.61),
number of branches plant
-1
(14.76) were observed at 80 DAT, the highest number of
flowers plant
-1
(109.24), fruits plant
-1
(98.81), fruit length (6.93 cm), fruit diameter
(0.58 cm), individual fruit weight (1.69 g), average fruit weight plant
-1
-1
(169.05 g) and
fruit yield ha
-1
(27.35 t) were recorded from Zn
2
treatment. Considering combined
effect of S and Zn, growth contributing parameter such as the tallest plant (74.83 cm),
number of leaves plant
-1
(101.32), maximum number of branches plant
(16.74),
highest number of flowers plant
-1
(121.26), maximum number of fruits plant
(114.09),
highest fruit length (7.79 cm), highest fruit diameter (0.63 cm), highest individual fruit
weight (1.78 g), average fruit weight plant
-1
(203.49 g) and fruit yield ha
(33.52 t)
were recorded from S
1
Zn
2
. Meanwhile, the lowest values of the parameters were found
in the control application of sulphur and zinc. Therefore, it can be concluded that 20 kg
ha
