The aim of this study was to investigate the nutritional and microbial quality of yoghurt from different districts of Bangladesh. Protein content was higher (4.56g/kg) in SB₂ (sample Bogura-2), fat content was also higher (5.67g/kg) in SB₃ (sample Bogura-3). The acidity found ranged from 0.77% to 0.98%, pH obtained ranged between 3.6 to 4.98 and total solid retained between 23.08 to 26.95 for all samples. Highest Total Viable count (TVC) value was found in SB₂ (68.9×10⁴±0.23 CFU/ml) and lowest value was observed in SJ₂ (23.01×10⁴±0.43 CFU/ml). No mold and yeast were found in the collected samples during study period that indicates all are follow hygiene procedure but all of the yogurt samples were contaminated with fewer amount (5.6±0.66 to 12.56±0.44 CFU/ml) of coliform. The mean value of acceptability score of yogurt sample was higher (99.2) in SB2 (sample Bogura-2) during the study period. Organoleptically, the overall quality of all yogurt samples was good. Considering the pH, acidity, total solids, protein, fat, carbohydrate and ash values for all yogurt samples collected from Bogura had better quality as compared to other samples. From the present study, it was found that all of the samples collected from Bogura district were much better quality compared to other samples in terms of nutritional, biochemical and microbial aspect. All of the samples were found in contaminated with lower amount of coliform so necessary actions should be taken in every step of processing, maturing and marketing to overcome this problem.

The present research work was carried out to evaluate the qualities of borhani prepared by curd using whole milk, skim milk and full cream powder milk. In this purposes, three types of borhani were prepared, these were grouped as; A: Borhani prepared from whole milk curd, B: Borhani prepared from skim milk curd and C: Borhani prepared from full cream powder milk curd. The prepared borhani samples were subjected to organoleptic, chemical and microbiological qualities. After performed physical examination, for sample A it was found that there was no significant difference in color and appearance (17.67±0.33) but there was significant difference (p<0.05) in smell and taste (47.33±0.33), body and consistency (26.33±0.33) and total physical scores (91.33±0.88) of the three borhani samples. Chemical analysis showed that for group A; there were significant differences with others (p<0.01) in contents (%) of fat (2.95±0.33), total solids (TS) (18.15±0.16), acidity (0.80±0.01), pH (4.25±0.02), moisture (81.85±0.16), CHO (10.50±0.93) and (p<0.05) in contents (%) of ash (1.82±0.02), protein (2.88±0.02). The result of chemical parameter showed that borhani prepared from whole milk (sample A) was best among the samples. However, there were no significant differences in coliform count and yeast and mold count but there were significant differences (p<0.01) in total viable count (60.67±2.33). Cost analysis showed that samples B and C was cheap than sample A. It can be concluded that even costly; the nutritive value and the consumer preference of borhani from whole milk was better than the others.

A field survey was conducted to investigate the farmers’ socio-economic status and management practices of buffaloes along with profitability analysis of buffalo rearing at Madargonj upazila of Jamalpur district. The data were collected during October to December 2018 from 60 buffalo keepers randomly selected from four unions of Madargonj upazila through pre-tested and pre-designed interview schedule. Buffalo rearing was practiced by the middle (30-40 years) aged farmers (51.7%) and almost three fourth of the farmers were illiterate. Buffalo keepers (40%) had medium sized family and belonged to small category of farmers (50%).Farmers usually purchased one pair of buffaloes and reared for 2 years but they (86.7%) reared buffaloes as their family heritage without any training. Majority of the farmers reared crossbred buffaloes having herd size of 4-10 buffaloes. Buffalo houses were constructed by straw (63.4%), tin (28.3%) and only 8.3% half building. Buffaloes were fed usually with locally available river side grasses and concentrate feeding was not found in majority of cases (75%). Natural service was the major practice for breeding of their buffaloes. The most prevalent disease is foot and mouth disease although buffaloes were affected by others. Most of the farmers (66.7%) performed wallowing of their buffaloes once a day. Yearly expenditure, gross income and net income were Tk. 9570, Tk. 26400 and Tk. 16830; respectively indicating that buffalo rearing is highly profitable in Madargonj. The annual food and cloth purchasing capacity of the buffalo farmers were found to be increased to 65.60 and 57.24%, respectively along with other parameters. The findings of this study clearly indicated that socio-economic profile of buffalo farmers was improved through buffalo rearing although the management practices need to be improved with scientific approaches.

Integrated use of organic and inorganic fertilizers could improve both growth and yield of okra plant. The present study was carried out to evaluate the effect of organic and inorganic fertilizer on growth and yield parameters of okra (Abelmoschus esculentus L.) at experimental area of Noakhali Science and Technology University, Bangladesh during the period of 18^th December, 2018 to 19^th March, 2019 (Rabi season). In this experiment, “Arka Anamika” variety of okra was used. The experiment was laid out in Randomized Complete Block Design (RCBD) with four treatments viz. T1= INM (organic and inorganic), T2= Inorganic (NPK), T3= Organic (cowdung), T4= Control and three replications. Data were taken on the growth and yield parameters such as plant height (cm), number of leaves per plant, number of branches per plant, days to first flowering (days), number of fruit per plant, individual fruit weight (gm), fruit length (cm) and fruit diameter (cm). Among all treatments INM (organic and inorganic) was responsible for highest plant height (49.96 cm), maximum number of leaves per plant (22.33) and branches per plant (6.33), accelerated days to first flowering (39 days), increases the number of fruit per plant (14.33), individual fruit weight (24.89 gm), fruit length (15.5 cm) and fruit diameter (1.98 cm). So this study clearly indicated that, among all treatments INM (Organic and inorganic) performed the best and it will be suitable for okra production.

Shyamnangar upazila one of the potential developing upazila of Satkhira district. Addressing social aspects is very important for any sorts of development effort. The best possible use of land resources; therefore,the socio-economic aspects of Shyamnangar upazila have to be addressed to gain optimum economic benefits from agriculture, forestry, fisheries, tourism and industrial sector. The socio-economic transformation of this upazila significantly depends on the performance of the agricultural sector. Besides agriculture, fisheries, tourism, industry, weaving and livestock farming are also playing vital roles in the socio-economic development of this upazila. Although this upazila has not yet been experienced in planned industrialization but, there are some small and medium industries which are contributing largely to the socio-economic development. Over thelast 10 years, the socio-economic condition of the upazila is gradually rising. The growing of small & medium industries, business associated with agricultural products are the key element of socio-economic growth of Shyamnagar. Over the last 10 years, the socio-economic condition of the upazila is gradually rising.
