AGRICULTURAL EXTENSION AND INFORMATION SYSTEMThe purpose of this study was to determine the extent of awareness towards safe fish feed by the
carp fish farmers and to explore the relationships between the selected characteristics of the fish
farmers and their awareness. Data were collected from 101 fish farmers of 2 unions of Kishorganj
Upazila under Nilphamari district. An interview schedule followed by a pretested structured
questionnaire was used for data collection during the period from 15 January, 2021 to 14 February,
2021. Descriptive statistics such as mean, standard deviation, percentage and Pearson’s Product
Moment Coefficient of Correlation (r) were used for data analysis. About 44.5 percent of the
farmers had moderate awareness compared to 34.7 percent of them having highly aware and 20.8
percent having less awareness. Thus, the vast majority (78.2 percent) of the farmers’ have
moderate to highly awareness. Farmer’s education, experience in fish farming, time spending in
farm, annual income from pond fish farming, extension media contact and training exposure had
significant positive relationship with the awareness by the fish farmers. Farmer’s Age and Family
size had no significant relationship with the awareness by the fish farmers. It was recommended
that step should be taken by the concern authority for strengthening the farmers’ capacity for increasing the awareness towards safe feed for carp cultivation by the fish farmers

in relation to sowing time in the field of Sher-e-Bangla Agricultural University
farm, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from
November 2008 to March 2009. In these study the environmental factors were
evaluated at three time e.g.23 November, 30 November and 06 December,
2008. The experiment comprised of the following treatments; T1: Confider
70WG @ 3 g/kg seeds; T2: Zinger extract @ 20 ml/L water at 7 days interval;
T3: Turmeric extract @ 20 ml/L water at 7 days interval; T4: Neem leaf extract
20 ml/L water at 7 days interval and T5: Control. Three experiments were laid
out in three sowing times. Each experiment was set in a Randomized Complete
Block Design (RCBD) with three replications. For sowing on 23 November
2008, the lowest number of aphid and sawfly was recorded from T4, while the
highest number obtain from T5 treated plots at early, mid and late flowering
and fruiting stages. The seed yield per hectare was recorded highest from T4
(2.34 t/ha), while the lowest from T5 (2.01 t/ha) treated plots. Sowing on 30
November, 2008 showed the lowest number of aphid and sawfly in T4, while
the highest number from T5 treated plots at early, mid and late flowering and
fruiting stages. The highest yield was obtained from T4 (2.64 t/ha), while the
lowest yield was recorded from T5 (2.02 t/ha) applied plots. Mustard sown on
06 December, 2008 the lowest number of aphid and sawfly in T4, while the
highest number in T5 treated plots at early, mid and late flowering and fruiting
stages. The highest yield was recorded from T4 (2.21 t/ha) and the lowest yield
from T5 (1.95 t/ha) applied plots

SEMESTER: JANUARY-JUNE, 2016The experiment was conducted in the experimental area of Sher-e-Bangla Agricultural
University, Sher-e-Bangla Nagar, Dhaka during the period from April to August 2016,
to evaluate the effect of different doses of nitrogen fertilizer (urea) on the incidence of
sucking insect pest of rice. BRRI dhan43 were used as the test crop in this experiment.
The experiment comprised of the following nitrogen doses as treatment- T1 = Top
dressing of Nitrogen fertilizer (urea) @ 50kg/ha at three equal split application; T2 =
Top dressing of Nitrogen fertilizer (urea) @ 60kg/ha at three equal split application; T3
= Top dressing of Nitrogen fertilizer (urea) @ 70kg/ha at three equal split application;
T4 = Top dressing of Nitrogen fertilizer (urea) @ 80kg/ha at three equal split
application; T5 = Top dressing of Nitrogen fertilizer (urea) @ 90kg/ha at three equal
split application and T6 = Untreated control. The experiment was laid out in a
randomized complete block design (RCBD) with three replications. Data was recorded
on insect pest incidence, number of healthy, infested plants, leaf and tillers due to
different insect pests and infestation level and also yield contributing characters and
yield of BRRI dhan43 from different treatments. It was revealed that 3 common species
of sucking insect pests such as brown plant hopper, green leaf hopper and rice bug were
found in rice field. Insect populations for 5 selected hills/plot were observed and
sucking insect pests e.g., brown plant hopper, green leaf hopper and rice bug were
investigated. In case of tillers, leaf and panicle infestation in different crop stages
caused by different rice sucking insect pests, the lowest infestation was recorded from
T3, whereas the highest infestation was observed from T5. In consideration of yield
contributing characters and yield of BRRI dhan43, the maximum number of filled
grains/panicle (93.38%) was recorded from T3, while the minimum number of filled
grains/panicle (73.36%) from T6. The highest grain yield (4.25 t/ha) was recorded from
T3, while the lowest grain yield (1.24 t/ha) was recorded from T6 followed by T5
(2.55t/ha). Among the different nitrogen doses; 70 kg N/ha applied in T3 treatment was
superior to other nitrogen doses

SEMESTER:JULY-DECEMBER, 2009The experiment was conducted at the experimental field of Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh during the period from June to
November, 2009 to find out the most effective management practice(s) among
Trichogramma evanescens egg parasitoid @ 0.25 gm and 0.50 gm plot-1, Bacillus
thuriengiensis bacterium suspension @ 0.1% and 0.2%, SafeClean @ 0.05%,
SafeMax @ 0.05%, Neem oil @ 0.3% and chemical insecticide Furadan 5G @ 6 gm
plot-1 for the eco-friendly management of rice stem borer on hybrid rice (Hira-2). The
experiment was laid out in Randomized Complete Block Design (RCBD) with three
replications. Considering the dead heart and white head infestation, among the
treatments chemical insecticide Furadan 5G (T8) performed as the most effective
practice in reducing the dead heart (81.47%) and white head (91.44%) infestation over
control followed by Trichogramma egg parasitoid @ 0.50% (T2) treatment (73.64%
and 82.34%, respectively). T8also gave the maximum yield contribution characters of
the rice plants as well as produced the highest grain yield (7.67 ton ha-1) followed by
T2 (7.23 ton ha-1). Economically the most effective treatment was T2, through which
the highest benefit cost ratio (5.04) was achieved as compared with other treatments
including Furadan 5G (3.80). Considering the ecological point of view, the T2
comprising Trichogramma evanescens egg parasitoid @ 0.50 gm plot-1 was the most
ecologically sound management practice applied against rice stem borer

GENETICS AND PLANT BREEDING
SEMESTER: JULY-DECEMBER, 2012A field experiment was conducted at the Agricultural Farm of Sher-e-Bangla
Agricultural University, Sher-e-l3angla Nagar, Dhaka, Bangladesh during the rabi season
of November 2011 to February 2012 to characterize and genetic diversity analysis of 21
radish varieties based on some physiological characters. Four distinct clusters were
observed among the radish varieties on the basis of total dry matter (TDM), relative
growth rate (RGR). crop growth rate (CGR). leaf area index (LAI), net assimilation rate
(NAR), leaf area ratio ([AR). leaf weight ratio (LWR), leaf number per plant, harvest
index (HI), days to harvest and root yield per plant. Cluster IV consisted of the highest
number of varieties, viz.. Mino Early Long White (Ufsi Mula), BARI Radish-S (Druti),
Mino Long White, Early White-35, Chaniak, Nong Woo Bio (F1 hybrid), Radish Royal-
40, White Prince (F1 hybrid radish). Cluster II composed of Lucky (Early 35 Days),
Paira-40, Bright White 40, Rupsa, Tasakisan (China). Rocky-45. Cluster III composed of
Snow White (IF1 hybrid). BARI Radish-2 (Pinky), BARI Radish4. Barisal Local,
Ramboo-40. BARI Radish-I (Tasakisan) and Ivory White formed cluster 1. The highest
root yield was observed in cluster 1(380.06) which also produced the highest 1DM and
[Al. The longest cluster distance was observed between cluster I and cluster II.
Clustering pattern was not influenced by the genotypic origin. Ivory white produced the
highest root yield, TDM, and LA! which was followed by BARI radish-I. Ivory white
did not flower in growing season. BARI radish-2 produced the highest ROR and NAR.
Rupsa produced the highest harvest index. Leaf area index, LAR, LWR and leaf number
per plant were the major components of genetic divergence in the radish varieties.
Considering genetic diversity and other performances. BARI radish-I, BARI radish-2
and Rupsa appear to be promising parents for future hybridization program
