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.

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.

Abstract

The study on the damage potentiality and eco-friendly management of red pumpkin beetle on squash was carried out under open field condition at Sher-e-Bangla Agricultural university SAU), Dhaka during the period from October, 2018 to March, 2019. The experiment consisted of seven different treatments viz. T1 = Cultural method (clean cultivation to keep the plot free from weeds and debris & collect grub of Red pumpkin beetle ); + mechanical control method (removal of infested roots, shoots and fruits) at 7 days interval, T2 = Applying Sevin 50 WP @ 1.5g/pit + using vinegar trap, T3 = Mechanical control method at 7 days interval + using Funnel Pheromone trap, T4 = Applying Sevin 50 WP@1.5g/pit+ Spraying Folithion 50 EC@ 1.0 ml/L of water at 15 days interval, T5 = Spraying Pychlorex 20 EC @ 1.0 ml/L of water at 15 days interval + using Pheromone trap, T6 = Spraying Predator 50 EC @ 1.0 ml/L of water at  15 days interval + using mashed sweet gourd trap and T7 = Untreated control. The minimum number of red pumpkin beetle plant-1 ranging from 0.47 - 2.27 at different growth stages was recorded from treatment T4. The lowest percentage of leaf infestation and long petiole plant-1 were in the range of 9.38 – 12.90 and 8.41 – 11.65, respectively with the treatment T4. Likewise,  the highest number of healthy flowers plant-1 (14.27) was recorded from T4 whereas, the lowest percentage of infested flowers (2.7 – 2.73) was also found with T4. But at 45 and 55 days after transplantation, the highest number of healthy fruit plant-1 and lowest infestation was recorded from T5.  The highest percentage of cucurbit fruit fly control (80.42 - 82.41) was also recorded from T5. The highest single fruit weight (460.00 g),  length of fruit(23.10 cm), width of fruit (2.85 cm) fruit weight plant-1 (3.80 kg), fruit weight plot-1 (34.21 kg)  and yield (57.02 t ha-1)  was recorded from T5. Based on the least leaf infestation, it might be concluded that T4 was satisfactory, but for controlling Red pumpkin beetle T5 manifested better results.
