PRODUCTION STRATEGY AND ITS EFFECT ON SPOTTED DEER AT NATIONAL ZOO IN BANGLADESH
Get PDFThe production and reproduction profile, feeds and feeding and herd management of
spotted deer studied in captive condition at Bangladesh National Zoo in this
experiment. For these purposes, fifteen (15) deer’s from each group i.e. adult male
(Stag or buck), adult female (Doe), juvenile and infant were used during January 15
to December 15
th
2018 for a period of eleven months. Available feeds that were
supplied to the spotted deer such as maize fodder, Jambu grass and Gourd Spinach
(Kolmi grass), cabbages, cucumber, gourd, pumpkin, grain, wheat bran and soybean
meal. Amount of CP and metabolic energy was 13.63% and 14.38 MJ ME per day
respectively. From the study it was observed that average males and females’ birth
weights were 2.97 and 2.73 kg, adult males and females weights 78.08 and 60.97 kg,
males and females weaning weights were 19.05 and 18.49 kg respectively. It was
also observed that average weaning age was 5.19 months, length of estrous was 17.
40 days, age at first fawning was 14.48 months and gestation lengths were 232.69
days respectively. It is concluded that recommended rations need to be fed with
proper management systems to keep balanced nutritive conditions along with
productive and reproductive well-being of the spotted deer at Bangladesh National
Zoo

DEPARTMENT OF HORTICULTUREA field study was carried out in January-October 2021 to evaluate the effect of deficit
irrigation on physiology, plant growth, and yield of cucumber cultivars. The experiment
was conducted in a completely randomized design with three irrigation levels (I
0
=100% field capacity, I
1
= 80% field capacity and I
2
= 60% field capacity) as main plot
factor and three cultivars (V
1
= Mamra, V
2
= Baromashi and V
3
= Maroon) as subplot
factor with three replications. Regarding irrigation levels, I
0
(100%) showed the highest
plant height and highest number of leaves of 260.12 cm and 165.44 respectively, I
1
(80
%) produced the highest cucumber fruit yield of 2001.98 gm/plant while I
2
(60 %)
produced the lowest yield of 951.37 gm/plant. In the matter of combined effect, V
1
resulted in maximum vine length (248.20 cm), number of leaves (124.67), female flower
(16), fruit per plant (9), fruit weight (392.17 gm) and yield (3588.03 gm) were recorded
from the combination of I
0
and I

= 0.3%, T
5
= 0.4% and T
6
= 0.5%. A significant variation was observed in the Boro
seedlings characters including seedling height, fresh weight, oven dry weight, seedling strength
and chemical properties of the seedbed soils in all the sowing dates. Seedling characters values in
all the sowing dates were lowest in the control against the treatments. Seedbed application of the
chitosan raw material powder significantly improved the Boro seedling characters at 25 days after
sowing (DAS), 30 DAS, and 35 DAS in the different sowing dates. The seedling height, fresh
weight, oven dry weight and seedling strength were increased in a dose dependent manner with
the application of chitosan raw material powder up to sowing date S
8
. In the 1
st
sowing date values
of the seedling characters were maximum then gradually decreased and lowest value was found in
the last (8
th
) sowing dates. Seedlings produced in the 1
st
sowing date at 35 DAS were performed
superior than the seedlings of 30 DAS and 25 DAS. But the some treated seedlings of the 25 DAS
and 30DAS were performed significantly better than control seedlings of the 35 DAS. Grain yield
production of the S
1
seedlings (25, 30 and 35 days old seedlings) was higher in the treated
seedlings over the control seedlings. 35 day aged seedling treated with 0.3% chitosan raw
materials powder (35DT
3
) was shown higher yield pot
-1
(65.02 g) performance which 21% yield
increase over control. On the other hand, a significant improvement was observed on the seedbed
soil properties including organic carbon, organic matter, soil pH and total nitrogen content. The
maximum value of the seedbed soil properties was recorded in the T
6
treatment and minimum
level was recorded in the control treatment (T
1
). The increments of the organic matter content and
total nitrogen content were in a dose dependent manner. The results indicated that chitosan raw
material powder could play a significant role in the improvement of Boro seedling characters and
yield performance under the optimum sowing dates and also after the optimum sowing dates.
Chitosan raw material treated 30-35 days old Boro seedling could be recommended for the
farmers use. Low temperature induced seedling growth reduction could be manipulated through
using CHT raw material powder in seedbed

AGRICULTURAL EXTENSION & INFORMATION SYSTEMFish are a source of cheap protein to many rural communities in Bangladesh. Unfortunately,
very few fish farmers are not willing to adopt modern fish farming technologies in order to
boost fish production. The purpose of this study was to determine the extent of use of selected
fish farming modern technologies by fish farmers and to explore the relationship between
selected characteristics of the farmers and their use of modern fish farming technologies. The
selected characteristics were age, education, family size, fish farm size, annual fish farming
income, training received in fish farming, fish farming experience, social mobility, contact with
extension media, organizational participation and knowledge of farmer on fish farming. Data
were gathered from proportionally and randomly selected 101 respondents (farmers) of Trishal
Upazila under Mymensingh district by using a pretested interview schedule and the entire
process of collecting data was completed in July to December, 2022. Apart from descriptive
statistical methods, Pearson's Product Moment Correlation Co-efficient analysis was used in
order to analyse the data. Data revealed that highest portion (46.53 percent) of the fish farmers
had medium use of selected fish farming technologies, while 20.79 percent had low use and
32.67 percent had high use of the selected fish farming technologies. So, it can be said that
there was scope to increase the use of modern fish farming technologies in the study area. Out
of eleven selected characteristics of the fish farmers, education, fish farm size, annual fish
farming income, fish farming experience, training received and knowledge on fish farming had
positive and significant relationship with their use of modern fish farming technologies. On the
other side, age, family size, social mobility, extension media contact and organizational
participation had no significant relationship with the farmer's use of modern fish farming
technologies. The pond owners faced such major problems as fish diseases, lack of quality feed
and other chemicals, transportation problem, high investment etc. Modern fish farming
technologies need to be fully embraced to raise both food and nutrition security particularly in
rural communities. It is recommended that attempts should be taken by the Department of
Fisheries (DoF) and other fisheries advisory service providing organizations to increase the
knowledge and practice of the farmers on fish farming by providing necessary trainings and
motivations

GENETICS AND PLANT BREEDINGEight genotypes of Onion (Allium cepa L.) were evaluated to find out the genotypes for
drought tolerance using morpho-physiological and yield contrasting indices at Sher-eBangla
Agricultural
University,
Dhaka
during
July,
2021
to
June,
2022.
The
experiment
was
laid out in Complete Randomized Design (CRD) with three replications. Mean
performance, genetic parameters, Pearson’s correlation coefficient, and principal
component biplot analysis on different yield contributing characters and yield of onion
genotypes were estimated. The longest plant (49.43 cm) was recorded in the genotype
Lal Teer King, while the shortest plant (20.287 cm) was found in onion genotype BARI
Piaj 3. The highest bulb yield/plant (34.50 g) was recorded in the genotype of Lal Teer
King, whereas the lowest bulb yield/plant (21.38 g) from the genotype of BARI Piaj 3.
Phenotypic coefficient of variation was higher than the genotypic coefficient of
variation for all the yield contributing traits indicating drought stress influenced the
genotypes. In Pearson’s correlation study, yield per bulb positively and significantly
correlated with plant height (0.818), root length (0.511), no. of leaves (0.744), leaf
length (0.720), leaf breadth (0.756), bulb length (0.469), bulb diameter (0.716), leaf
area (0.893), chlorophyll content (0.886) and dry weight per bulb (0.854). The positive
and significant correlation observed between grain yield and traits under-drought stress
conditions provided evidence that studied traits might ultimately be considered as a tool
for effective selection of drought tolerant genotypes. Path coefficient analysis revealed
to that plant height had direct positive effect (5.058), root length had direct positive
effect (0.263), no. of leaves had direct positive effect (1.129) and dry weight per bulb
had direct positive effect (0.44) on yield per bulb, indicating these were the main
contributors to yield per bulb. The study selected 8 genotypes with high grain yields
under drought stressed conditions and favorable adaptive traits useful for breeding. In
consideration of yield contributing characters and yield Lal Teer King performed better
under drought condition followed by BARI Piaj 1, BARI Piaj 2, BARI Piaj 3,
