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.

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.

Abstract

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.

Abstract


The study was conducted to examine the profitability of shrimp farming in Bagerhat and Khulna district of Bangladesh. Besides, attempt was made to examine the factors influencing the shrimp cultivation and identify the constraints faced by smallholder cultivators in the study area. Bagerhat and Khulna districts were selected purposively for the study on the basis of extensive shrimp cultivation. A total of 120 shrimp cultivators were randomly selected to conducting farm level survey with pre-tested questionnaire. Data were collected during 1st November to 31st December, 2017. After analyzing the data, per hectare gross return, net return and gross margin were found to be Tk. 300900, 231468 and 273269, respectively. Total cost of shrimp production was calculated at Tk. 154608 per hectare. Benefit Cost Ratio was found to be 2.497 for shrimp farming which proved that the shrimp farming was highly profitable. Production function analysis suggested that, among the variables included in the model, cost of human labour, cost of fingerling and cost of feed had a positive and significant effect on gross return of shrimp production. On the other hand, cost of lime had a positive and insignificant effect on gross return of shrimp production and cost of urea and cost of TSP had a negative and insignificant effect on gross return of shrimp production. Most of the farmers reported that lack of capital was the main constraint for their shrimp production.

Abstract

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.

Abstract

An experiment was accomplished at Sher-e-Bangla Agricultural University during the period of July 2018 to January 2019 to adopt flower forcing technology for off season mango production. The study comprised four treatments (i) Control: No chemical application, (ii) 1g PBZ L-1 (Paclobutrazol) water, (iii) 0.5g PBZ L-1 water and (iv) 0.25g PBZ L-1 water following completely randomized design with six replications. Data on flowering and fruit related parameter were taken and significant variation was observed with different treatments. Among them, maximum inflorescence number plant-1 (8.7), fruit number inflorescence-1 (4.5), fruit number plant-1 (30.8), harvested fruits plant-1 (8.3), fruit length (11.7cm), single fruit weight (273.8 g) and yield plant-1 (2.3 kg) was found in T2 treatment whereas, maximum days required to first flowering (100.0 days), minimum inflorescence number plant-1 (3.2), fruit number inflorescence-1 (3.0), fruit number plant-1 (12.3) recorded in T3 treatment and no flowering was observed in control. So, it could be concluded that, significant treatment effects were observed on different parameters where T2 treatment (0.5g PBZ L-1 water) gave best results. Therefore, it can also be articulated that a new flower forcing technology is developed which will be potential for off season mango production.

Abstract

The experiment was conducted at the Agronomy Field Laboratory of Patuakhali Science and Technology University, Patuakhali during January-June session of 2018 to evaluate the effect of variety and spacing on the resources use efficiency of maize. The experimental treatments comprised three maize varieties (V1= Proline, White Maize), V2=Pioneer and V3=Sunshine); and three spacings (S1=20 cm, S2=25 cm and S3=30 cm).The effect of variety, spacing and their interactions were significant. The interaction treatment  S2V2 showed significantly the highest values in plant height (256.67cm), number of leaf plant-1 (14.27), stem girth (2.64cm), stomatal conductance rate (1853.33), cob length (19.50 cm), cob breadth (5.00), number of grains row-1(38.47), number of grains cob-1(583.67), cob weight (146.33 g), grain yield (6.69 t ha-1), stover yield (8.23 t ha-1), biological yield (14.87 tha-1). But the interaction treatment S1V2 showed the highest leaf area index (3.95 cm2), number of rows cob-1(16.13). On the other hand, the interaction treatment S1V1 showed the highest PAR above canopy (1819.33), harvest index (45.77 %) and S2V1treatment showed the highest ground PAR (349.33), 1000 grain weight (343.33g). The interaction treatment S2V3 showed the highest chlorophyll content (96.67). It may be concluded that the variety Pioneer planted 25 cm apart was more productive compared to others.
