Abstract
An experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Dhaka- 1207 during the period from 24 November, 2019 to 10 March, 2020 to evaluate the effect of different levels of nitrogen and Sulphur, and to select the suitable combination of nitrogen and Sulphur for achieving maximum yield and oil content of sunflower. The experiment comprised of two factors with varying levels of nitrogen and Sulphur such as Nitrogen (N1 = 80 kg N ha-1, N2 = 100 kg N ha-1, N3 = 120 kg N ha-1 and N4 = 140 kg N ha-1) and Sulphur (S1 = 20 kg S ha-1, S2 = 30 kg S ha-1 and S3 = 40 kg S ha-1). The experiment was laid out in a split plot design with three replications. Data were collected on different aspects of yield attributes, yield and oil content of sunflower. Results revealed that higher doses of nitrogen (N4 and N3) gave the highest grain yield (1.82 and 1.76 t ha-1, respectively) which may be attributed to the maximum head diameter (16.38 and 15.56cm, respectively), seeds head-1 (374.11 and 366.17, respectively) and 1000- seed weight (59.74 and 59.34 g, respectively) in these two nitrogen doses. Out of 3 doses of Sulphur, the highest dose (S3) produced the highest seed yield (1.81 t ha-1). This treatment also showed highest leaf area index (1.0950), SPAD value (49.12), seeds head-1 (3366.03) and 1000- seed weight (58.59g). However, N2 and S3 treatment showed highest oil content (in percentage). Regarding the interaction of nitrogen and Sulphur doses, the interaction of highest nitrogen dose (N4) × highest Sulphur dose (S3) (N4 × S3) was maximum seed yielder (2.08 t ha-1) among the other interactions which was attributed to higher head diameter (16.99 cm), seeds head-1 (382.31) and 1000- seed weight (60.36 g) in this interaction treatment. On the other hand, N2 × S3 interaction gave maximum oil content in terms of percentage.
Keywords: Sunflower, Growth, Yield and Oil content.

Abstract
The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University of Bangladesh during the period from October, 2019 to March, 2020 to evaluate the ecofriendly management of cucurbit fruit fly (Bactrocera cucurbitae) in bitter gourd. Seven treatments such as; Pheromone trap, Vinegar trap, Sweet gourd bait trap, Banana bait trap, Neem seed extract, Datura seed extract and Untreated control were used in the field. The experiment was laid out following Randomized Complete Block Design with three replications. The highest yield increase (183.27%), fruit length (38.30%) & girth (97.86%), number of fruits per plant (156.67%) was achieved by Sex pheromone trap. The highest yield (23.03 ton/ha) was also achieved by Sex pheromone trap followed by 22.16 ton ha-1 in Sweet gourd bait trap. Sex pheromone trap also showed similar performance in terms of weight of single fruit, length of fruit, girth of fruit and yield. It also reduced the fruit infestation. Considering the results of the present study, it can be concluded that the Sex pheromone trap may be used for the management of cucurbit fruit fly in bitter gourd.

The main purpose of the study was to determine farmers’ perception on the effectiveness of using ICT for receiving agricultural information and to explore the relationship of the selected characteristics of the farmers. The study was conducted in six Upazilas namely Narsingdi Sadar, Monohordi, Shibpur, Polash, Raipura & Belabo under Narsingdi district. Data were collected from 109 farmers using a pre-tested interview schedule during the period from 15 February to 15 April, 2018. Pearson Product Moment Correlation test was used to explore the relationships among the concerned variables. The study revealed that the highest proportion i. e. 57.8% of the respondents had medium level of perception on the effectiveness using ICT for receiving agricultural information compared to 25.7 % and 17.5 % having low and high level of perception respectively. Significant relationship of focal variable was found with farmers’ age, education, farming experience, cosmopoliteness, extent of using ICT, innovativeness and problem confronted by the farmers during ICT use. No significant relationship was found with farmers’ farm size, annual family income and organizational participation. It may be concluded that different government agencies of Bangladesh like DAE should provide necessary training programs to the farmers so that they understand the benefits of using ICT for receiving agricultural information.

Participation of women in homestead agricultural sector is a
crucial issue in developing countries like Bangladesh. The study was conducted
in two selected villages of Kapasia Upazila under Gazipur district of
Bangladesh to assess the nature and extent of women’s participation in
homestead agricultural activities. Fourteen types of issues namely age,
education, family size, family firm size, organizational participation,
exposure to mass media, training, knowledge in the different homestead
agricultural activities, participation in the homestead agricultural
activities, comparative participation in different homestead agricultural
activities, participation in homestead vegetables and fruit cultivation,
participation in post-harvest activities, participation in poultry and
participation in cattle rearing were investigated in this study. This research
was conducted from randomly selected 90 farm women from the two selected
villages during July to August, 2011.
Most of the rural women were found to participate in homestead vegetable
and fruit cultivation, post-harvest activities, poultry raising and cattle
rearing. In case of vegetable and fruit cultivation, majority of the rural
women regularly participate in activities like harvesting, weeding, mulching
and irrigation. It was found that extent of participation of the rural women in
post-harvest activities and poultry raising were also high. Educational status,
family farm size, organizational participation, exposure to mass media,
training experience and knowledge about different agricultural activities showed
significant positive relationships with their participation in homestead
agricultural activities. Major problems faced by the rural women in homestead
agricultural activities were lack of good quality seeds in proper time,
shortage of irrigation water for agricultural production, lack of knowledge for
improved crop production, lack of adequate quantity fertilizer in proper time
and insect attack, respectively.
