SEMESTER: JANUARY-JUNE, 2019The study was conducted to determine the extent of use of ICTs by the flower farmers
and to determine the extent to which the selected factors influence their use of ICTs for
production and market-related information in selected areas of Jhikargacha upazila
under Jashore district. Three unions namely Panisara, Godkhali, Nabharan of
Jhikargacha upazila were randomly selected as the research area. Data were collected
from 106 randomly selected flower farmers from the study areas, through personal
interview by the researcher himself during 20 December, 2020 to 27 February, 2021.
Data were analyzed by Multiple Regression analysis using SPSS 23.0. Data indicates
that the highest proportion (45.3%) of the flower farmers moderate use ICT based
applications, while (35.85%) had less ICT based applications and less than one-fifth
(18.9%) had high use of ICT based applications for their flower production and market
related information. Results indicates that annual family income, extension media
contact, ICT ownership and ICT use skill were significantly contributed to their use of
ICTs while age, level of education, farm size, family member, organizational
participation, perceived benefit use were found non-significant predictors of ICTs use.
All the factors jointly explained 74.3% (R
2
= 0.743) of the variances of the dependent
variable. Thus, the study concludes with the recommendation to enable favorable
environment to promote use of ICT based applications in receiving flower production
and market related information

AGRONOMYThe experiment was conducted at the research field of the department of Agronomy,
Sher-e-Bangla Agricultural University during the period from November, 2019 to
March, 2020 for assessing cutting management effects on growth and yield
performance of different cereals. The experiment comprised of two factors viz. factor
A: Cutting (3); i) Uncut - C₁, ii) One cut at 25 Dates After Sowing (DAS) - C₂ and iii)
Two cuts at 25 DAS and 61 DAS - C₃; factor B: Crops (4), i) Wheat - G₁, ii) Triticale -
G₂, iii) Barley - G₃ and iv) Oat - G₄. This experiment was laid out in a randomized
complete block design (RCBD) with three replications. Significant differences were
observed among different cutting management with respect to yield and yield
attributing parameters of cereal crops. A yield advantages of 0.55 t ha⁻¹ and 1.45 t ha⁻¹
over C₂ (One cut at 25 DAS) and C₃ (Two cuts at 25 DAS and 61 DAS), respectively
was found which was possibly aided by the tallest plant at 80 DAS (105.79 cm), the
highest number of tillers m⁻² (67.54), the maximum number of leaves plant⁻¹ at 80 DAS
(22.27), maximum leaf area index at 80 DAS (11.06), the highest fresh weight at 80
DAS (101.00 g), highest dry weight at 80 DAS (39.41 g), the maximum number of
grains spike⁻¹ (54.42), the highest weight of grains spike⁻¹ (3.49 g), the longest spike
(18.87 cm), the highest straw yield (7.23 t ha⁻¹) and the highest biological yield (12.48
t ha⁻¹) in the C₁ (No cut) treatment. The result revealed that oat (G₄) exhibited its
superiority to other tested cereal crop that out-yielded over Triticale (G₂) and Barley
(G₃) by 35.59% and 16.00% higher yield, respectively. Oat (G₄) also showed the tallest
plant at 80 DAS (107.19 cm), the highest number of tillers m⁻² (77.25), the maximum
number of leaves plant⁻¹ at 80 DAS (21.92), maximum leaf area index at 80 DAS
(13.86), the highest fresh weight at 80 DAS (90.55 g), the highest dry weight at 80 DAS
(34.12 g), the maximum number of grains spike⁻¹ (56.66), the lowest number of unfilled
grains spike⁻¹ (2.35), the highest weight of grains spike⁻¹ (3.29 g), the longest spike
(26.91 cm), the highest straw yield (10.15 t ha⁻¹) and the highest biological yield (15.75
t ha⁻¹) than other tested cereal crops in this experiment. Among the interactions, C₁G₄
and C₂G₄ were superior in most of the growth, yield attributes and fodder production
along with grain yield and yield parameters along with higher amount of fodder
production. From the result of the experiment, it may be concluded that oat cut once at
25 DAS seemed promising as dual-purpose crop in Bangladesh

AGRICULTURAL EXTENSION AND INFORMATION SYSTEMBangladesh is a agriculture based country. Most of the people of our country is
related with agriculture. But due to low knowledge on agricultural operation or
modern agricultural machineries operation the farmer faced huge loss on crop
production. That’s why the modern agricultural machineries need in agriculture
sector to increase crop production. The modern machineries use in agricultural
operation is called mechanization. The purpose of the study was to describe the
selected socioeconomic characteristic of the farmers; to determine the extent of
farmers’ knowledge on agricultural machineries; and to explore the relationship of
the selected characteristics of farmers on their knowledge on modern agricultural
machineries. The study was undertaken purposely in Roumari Upazila under
Kurigram district. Validated and well-structured interview schedule was used to
collect data from 110 farmers. Data were collected by a pre tested interview
schedule during 16 jun 2022 to 15 july 2022. Simple and direct questions with
different scales were used to obtain information. Descriptive statistics, multiple corelation
were
used
for
the
analysis
of
collected
data.
The
majority
47.72
percent
of
the
respondents
had
low
knowledge
followed
by
21.81
percent
had
high
knowledge
and
35.45 percent of the farmers had medium knowledge on agricultural
machineries. Among 10 selected characteristics of the farmers 6 characteristics
namely, education, quantity of modern machinery, attitude of farmers towards using
modern agricultural machinery, annual family income, training exposure and
extension media contact, had positive significant relationship with their knowledge
on modern agricultural machineries but rest of four namely age, farm size,
experience in farming, organizational participation had no significant relationship
with their knowledge on modern agricultural machinery. Findings leads to
conclusion that farmers’ socioeconomic characteristics are important for acquiring
knowledge on modern agricultural machineries and concerned authority should
consider these characteristics to take necessary steps for improving knowledge of
farmers on modern agricultural machineries
