Both primary and secondary data were used. The study utilized tabular, mathematical and statistical techniques for data analysis. The study found that the BCR for the seasonal and the off-seasonal tomato production were 1.59 and 2.23, respectively, whereas the BCR for the seasonal and the off-seasonal bean production were 1.32 and 2.19, respectively. The study also found that, in season (November-March), the highest seasonal price index for both tomato and bean vegetables were found in November (i.e. 149.71 and 109.24, respectively). While in off-season (April-October), the highest seasonal price index for the tomato (i.e. 177.93) and the bean (i.e. 197.80) were found in September and August, respectively. In evaluating the risk management strategies, the study found that the frequency and the relative frequency of the application of manure and the use of insecticides were 100% for both season tomato and bean vegetables. On the basis of the findings and opinions of farmers during field visit, the researchers’ identified high cost of human labor, price fluctuation and deficiency of farmers’ awareness in term of different risk management strategies were the major problem. The researchers’ recommends that farmers should use friends’ contributory labor, planning appropriate harvesting period (i.e. early period for season and late period of off-season) and increasing farmers’ awareness by means of local and national level training. These findings will be helpful for farmers, researchers and policy makers to take informed production decision, formulation of future research work and policy development focusing vegetable sector of Bangladesh.

Reproductive performance data on 35 Brahman crossbreds, 32 Indigenous, 12 Sahiwal crossbreds and 21 Friesian crossbreds were collected from three different villages (Baera, Bhabkhali and Dowhakhola) adjacent to Bangladesh Agricultural University, Mymensingh. Statistical analyses were performed using Statistical Analysis System (SAS) computer program. Reproductive performance of Brahman crossbred was recorded as age at first service: 32.29 ± 1.46 months, age at first calving: 42.00 ± 1.49 months, service per conception: 1.7 ± 0.17, overall conception rate: 0.76 ± 0.05 (76.11%), conception at first service: 0.63 ± 0.08 (62.85%) and gestation length: 282.97 ± 0.78 days. Highly significant (p<0.001) effect of genotype was observed for age at first service and age at first calving; conception rate at first service differs significantly (p<0.05) among genotypes while service per conception, overall conception rate and gestation length were not significantly affected by genotype. Reproductive performance of Brahman crossbred heifer is within the moderate range and better for some traits (i.e. age at first service) than the other genetic groups studied (i.e. Indigenous, Sahiwal × Indigenous, Friesian × Indigenous).

Two hundred seventy respondents were surveyed randomly through structured questionnaires, focus group discussion (FGD) and key informant interview (KII) from July, 2018 to October, 2019. Young people (11-30-year group) were dominant in both the two stakeholder groups in haor and floodplain. Most of the stakeholders belonged to medium size family (5-8 persons) in both the groups. Access to education, electricity, kitchen, housing and sanitation facilities were comparatively better in IHs than PHs in both haor and Daudkandi floodplain fisheries (DFPF). In Kishoreganj haor, higher number of IHs possessed above 12 decimal of homestead land. The quality of life was comparatively better in IHs than PHs. About 45% IHs and 48.89% PHs in haor areas received health service from the Government hospitals, while it was 38.57% and 52% in DFPF, respectively. Monthly income and yearly savings were higher in IHs than PHs in both study areas. Lack of proper knowledge on pre-harvest, harvest and postharvest handling practices of fish from fishing to transport into retail markets were found to be the major constraints of poor quality and low price of fish. IHs had comparatively better well-being status than the PHs. It is, therefore, suggested that improved fish handling must be practiced by all the stakeholder groups to improve their well-being status.

The frozen meat has to be thawed before further processing. Quality deterioration occurs during the thawing process. The uniform-sized broiler chicken samples were individually frozen using an ultra-low temperature freezer (-40°C) for an overnight. The frozen meat samples were thawed in the refrigerator (4°C), cool room (20°C), hot air oven (60°C), tap water (27±5°C), and hot water conditions (40°C) until core temperature of the meat reaches 10°C in all method except refrigeration method where the core allowed to reach 4°C. Moisture content (MC), water holding capacity (WHC), drip loss (DL), cooking loss (CL), and pH were determined. There were significant differences (p<0.05) observed among the quality parameters of the samples, including MC, DL and CL based on the different thawing methods. However, there were no significant deviations in the pH and WHC. The sensory evaluation was also carried to evaluate color, taste, flavor, chewiness, juiciness and overall rating of the uniformly cooked samples by using nine hedonic scale techniques. There were no significant differences among sensory parameters of the samples (p<0.05). Of which, the highest rating was obtained for the cool room and tap water method, while the poor rating was for the refrigeration method. Therefore, the different thawing methods impact on the quality parameters of the frozen broiler chicken rather than influencing the sensory qualities. However, the cool room thawing method had minimized reductions in the qualities of the thawed broiler chicken followed by the tap water method.
