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 present investigation was undertaken to examine the effect of suitable spacing technique(s) of maize on the morpho-physiology, yield attributes, yield and nutrient composition of maize at the Entomology Field Laboratory, Department of Entomology, Bangladesh Agricultural University (BAU), Mymensingh during Rabi season of 2016-17. The research work was carried out in randomized complete block design (RCBD) with three replications. Maize var. BARI Hybrid Butta-09 was used as the test crop. Five spacing techniques (Distance of row to row and plant to plant, respectively were 50cm×20cm (T1), 55cm×25cm (T2), 60cm×30cm (T3), 65cm×35cm (T4) and 70cm×40cm (T5). All the spacing techniques showed significantly different performance on yield. It was revealed that the maximum morpho-physiological characters, yield attributes and yield was obtained with higher composition of nutrients by using technique of 60cm×30cm (T3). This treatment also showed the highest plant height (223.45cm), stem diameter (8.10cm), leaf length (74.25cm), number of cob plant-1 (1.74), cob length (22.20cm), number of grain cob-1 (710.13), grain weight cob-1 (230.67g), grain yield (10.11 t ha-1), protein content (10.45g), fat (3.46g), carbohydrate content (65.42g) and vitamin C (0.12g). Furthermore, based on yield of maize and nutrient composition, the increasing order of yield was S2>S4>S1>S5. Therefore, considering all facts, 60cm×30cm as the technique of spacing could be recommended to grow maize for obtaining higher yield quality.
