The present study was carried out to evaluate the rehydration characteristics of solar and mechanically dried lablab bean (Lablab purpureus (L.) sweet; hitherto Dolichos lablab) seeds. Bean seeds with and without coat were used to study the rehydration properties. The rehydration ratios were higher for both mechanically and solar dried bean seeds without seed coat than those with coat. Mechanically dried without coat bean seeds had rehydration ratio of 2.34 while with coat was 2.06. For mechanically dried samples, the co-efficient of reconstitution were 0.58 and 0.56 for bean seeds without and with coat, respectively, and were higher than those of solar dried samples having co-efficient of reconstitution of 0.54 and 0.52 for bean seeds without and with coat, respectively. For both mechanical and solar drying the rehydration rate constant was higher for bean seeds without coat than those with coat. Both rehydration ratio and rehydration rate indicated that mechanically and solar dried bean seeds samples without coat showed better reconstitution properties than those with coat. Both fresh and dried bean seeds without seed coat gave higher nutrient content than their counterpart with coat. Solar and mechanical dried seeds were good source of nutrients.

This is an applied reference book written by a soil scientist with practical experience, shows the importance of integrated nutrient management on vegetable production in home stead garden. It is a useful document of the valuable research findings on integrated nutrient management technologies developed by the author. Prescribing rational and balanced use of plant nutrients from both organic manure and inorganic fertilizers, Integrated Nutrient Management for Home stead Gardening covers wide range of vegetables including cabbage, radish, tomato, brinjal, okra, stem amaranth and red amaranth in pattern basis considering environmental, social and economic imperatives. It also explains the present constrains of soil fertility indicating possible measures for the maintenance of soil health. This volume contains huge bibliographical citations, tables and graphs, which have made it an incomparable resource book for Soil Scientists, Agronomists, Horticulturists, Plant Breeder, Extension Personnel, Teachers and Post-Graduate Students. Genuine and careful use of these recommendations would be very helpful in achieving food security and maintaining soil fertility and productivity.
The present study was conducted to investigate the status of current antibiotics use and vaccine application program in commercial broiler farming, to understand about the current market scenario of antibiotics and vaccine related products and to identify the major problems of broiler farming and suggestions for its improvements. For achieving these objectives, 50 broiler farms and 20 antibiotics-vaccine products sellers were selected purposively from 5 selected unions of Sakhipur upazila in Tangail district. In the study area, 42% respondent had a slim idea about residual effect of antibiotics. Most of the farmers in the visited area used almost same types of antibiotics. Among the farms surveyed, 98% farms practiced proper vaccination. Among the 50 farmers, 66% farmers had idea about sound vaccination program and 98% farmer thought that vaccination is essential for their farming. In the study area, 70% farmers got their antibiotics and vaccine from dealer. The study showed that antibiotic cost is only 3.53% and vaccination cost is 1.06% of the total cost. Regarding the antibiotics use, results were alarming and found that 100% respondents used antibiotics in broiler production. Both positive and negative significant correlations were observed for different parameters. The problems related to present antibiotics and vaccination program and their probable solutions suggested by broiler farmers were also focused in this study.Progressive Agriculture 27 (4): 490-501, 2016
Aquaculture and fisheries sectors have been reported to contribute in greenhouse gases (GHGs) emission, such as CO2, CH4 and N2O. This study evaluates the contribution of aquaculture and fisheries sector to GHGs emission in Bangladesh, where both sectors are set to continuous intensification over the next few years. Data were collected from primary sources using focus group discussions, key informant interviews and a national level workshop, and secondary sources during July 2015 to June 2016. This study quantified that fisheries and aquaculture annually emittes 3.68 Mt CO2e which contributes 1.87% to the country total and 4.94% of agriculture sector GHGs emission in Bangladesh. The emission from aquaculture subsectors (3.54 Mt CO2e per year) accounts for 96% of total fisheries sector emission. This study also found that the emission increases with the intensification of the production process. Due to continuous intensification over the years, aquaculture is now considered as one of the rapidly increasing industries in Bangladesh. Therefore, the country’s growing dependency on aquaculture will lead to higher GHGs emission potential in the future when the world is looking for lowering GHGs emission. This study identified potential mitigation measures to reduce the GHGs emission from aquaculture subsectors, like increasing fuel efficiency, reducing feed material emission intensity, reducing feed mill emissions and improving feed management. The findings of this study can serve as a preliminary guide to in-depth quantification of GHS's from fisheries and aquaculture. This study also expected to help policymakers to form fisheries and aquaculture development plans with reduced GHG`s emission.
In this experiment, an attempt was made to prepare dahi for diabetic patient and also to monitor the quality of prepared dahi by using different tests. For this purpose, artificial sweeteners such as sac-sweet and sucrol were added with milk to prepare dahi for diabetic patient. Milk sample was collected from the Bangladesh Agricultural University Dairy Farm. Three different types of dahi (A- dahi with sugar, B- dahi with sac-sweet and C- dahi with sucrol) were prepared by using the milk. From the results of physical scores it was found that overall score of A, B and C type dahi samples were 92.44 ± 1.83, 86.99 ± 4.70 and 86.45 ± 7.65, respectively (P>0.05). Average total solids, fat, protein and ash content of A, B and C type dahi samples were 243.43 ± 2.7, 149.73 ± 2.6 and 149.83 ± 2.5 (P<0.01); 44.33 ± 2.1, 49.00 ± 2.6 and 49.00 ± 2.6 (P>0.05); 36.17 ± 1.3, 40.07 ± 1.1 and 40.07 ± 1.1 (P<0.05); 7.67 ± 0.2, 8.43 ± 0.2 and 8.43 ± 0.2 (P<0.01) g/kg, respectively. It was observed that the values of above parameters (except total solids) for dahi prepared by using sac-sweet and sucrol were nearly similar to the dahi prepared by using sugar. But higher level of total solids for A type dahi was due to addition of 10% sugar with milk during dahi preparation. On the other hand, very small amount of artificial sweeteners were used in B and C type dahi just to increase the sweetness which had no or little effect to increase the totals solids content. So it can be suggested that acceptable quality dahi could be prepared by using artificial sweeteners like sac-sweet and sucrol for diabetic patient.
