Sher-e-Bangla Agricultural University or SAU is the oldest agricultural institution in Bangladesh and South Asia, situated in Sher-e-Bangla Nagar, Dhaka. It was established on December 11, 1938 as Bengal Agricultural Institute and later upgraded to university in 2001 renaming Sher-e-Bangla Agricultural University.Since its establishment, this university is playing a role in agricultural research and development of the region through creation of knowledge, agricultural technology generation and transfer, crop diversification and intensification for the benefit of farming communities. SAU offers undergraduate and post graduate degrees through course credit system and also Ph.D. courses. Wikipedia.

The increasing global demand for biomass of medicinal plant resources reflects the issues and crisis created by diminishing renewable resources and increasing consumer populations. Moreover, diverse usage of plants and reduced land for cultivation in the world accelerated the deficiency of plant resources. In addition, the preparation of safety of plant based medicine whips up demand for biomass of valuable medicinal plants. As one of alternative approach to upswing the productivity of plant-based pharmaceutical compounds, automation of adventitious root culture system in air-lift bioreactor was adopted to produce cosmic amount of root biomass along with enriched diverse bioactive molecules. In this review, various physiological, engineering parameters, and selection of proper cultivation strategy (fed-batch, two-stage etc.) affecting the biomass production and secondary metabolite accumulation have been discussed. In addition, advances in adventitious root cultures including factors for process scale-up as well as recent research aimed at maximizing automation of the bioreactor production processes are also highlighted. Examples of the scale-up of cultures of adventitious roots of Morinda citrifolia, Echinacea purpurea and angustifolia, Hypericum perforatum and Panax ginseng by applying 20. L to 10, 000. L bioreactors in our lab were demonstrated with a view of commercial application. © 2012 Elsevier Inc.

In vitro microtuber formation potentiality of potato was investigated to establish a rapid disease free seed production system in potato. MS medium supplemented with 4 mg/L of KIN showed best performance in respect of multiple shoot regeneration and microtuber formation. Simple MS medium was not able to produce any micro tuber under in vitro condition. Dark condition better responded to tuberization than light condition. Among the three different explants (nodal segment, sprout and shoot apex) nodal cutting showed the best performance on days to microtuber formation and average weight of microtuber. MS + 6% sucrose + 4 mg/L KIN combination of treatment was best for in vitro tuberization among the parameters under study.

In order to observe the possible regulatory role of selenium (Se) in relation to the changes in ascorbate (AsA) glutathione (GSH) levels and to the activities of antioxidant and glyoxalase pathway enzymes, rapeseed (Brassica napus) seedlings were grown in Petri dishes. A set of 10-day-old seedlings was pretreated with 25 μM Se (Sodium selenate) for 48 h. Two levels of drought stress (10% and 20% PEG) were imposed separately as well as on Se-pretreated seedlings, which were grown for another 48 h. Drought stress, at any level, caused a significant increase in GSH and glutathione disulfide (GSSG) content; however, the AsA content increased only under mild stress. The activity of ascorbate peroxidase (APX) was not affected by drought stress. The monodehydroascorbate reductase (MDHAR) and glutathione reductase (GR) activity increased only under mild stress (10% PEG). The activity of dehydroascorbate reductase (DHAR), glutathione S-transferase (GST), glutathione peroxidase (GPX), and glyoxalase I (Gly I) activity significantly increased under any level of drought stress, while catalase (CAT) and glyoxalase II (Gly II) activity decreased. A sharp increase in hydrogen peroxide (H 2O 2) and lipid peroxidation (MDA content) was induced by drought stress. On the other hand, Se-pretreated seedlings exposed to drought stress showed a rise in AsA and GSH content, maintained a high GSH/GSSG ratio, and evidenced increased activities of APX, DHAR, MDHAR, GR, GST, GPX, CAT, Gly I, and Gly II as compared with the drought-stressed plants without Se. These seedlings showed a concomitant decrease in GSSG content, H 2O 2, and the level of lipid peroxidation. The results indicate that the exogenous application of Se increased the tolerance of the plants to drought-induced oxidative damage by enhancing their antioxidant defense and methylglyoxal detoxification systems. © 2011 Springer Science+Business Media, LLC.

Renewable and Sustainable Energy Reviews | Year: 2015
This study examines whether crop diversification provides economy in energy use and improves technical energy efficiency using a large survey data of 2075 farms from 20 sub-districts of 17 districts in Bangladesh by applying a stochastic input-distance function approach. The results reveal that cereal production significantly increases energy use by 0.14% for every one percent increase' in output. Renewable source of energy constitutes 59.6% of total inputs and labour energy alone constitutes 39%. Significant output complementarity exists between cereal and oilseed enterprises but competition exist between jute with pulse and/or oilseed enterprises. The mean technical energy efficiency is estimated at 68% implying that energy output can be increased by 32% by eliminating inefficiency. Diversification amongst enterprises is associated with energy inefficiency, implying that specialization into cereals improves efficiency. Large farms are inefficient whereas large family size improves efficiency. The key policy implication is that diversification of crop enterprises must maintain cereal (i.e., rice/wheat/maize) as the main base and then add non-cereal crops (e.g., oilseeds) in order to improve energy economy. Also, diversification within cereals from rice monoculture to wheat and/or maize will significantly improve technical energy efficiency. © 2015 Elsevier Ltd. All rights reserved.

The term 'indicator' is often vague and heterogeneous, and its dynamic characteristics make it highly variable over time and space. Based on reviews and synthesis, this study visualizes phenomena and highlights the trend of indicator selection criteria, development methods, validation evaluation strategies for improvement. In contextualization of the intensification of agriculture and climate change, we proposed a set of indicators for assessing agricultural sustainability in Bangladesh based on theoretically proposed and practically applied indicators by researchers. Also, this article raises several issues of indicator system development and presents a summary after due consideration. Finally, we underline multi-stakeholders' participation in agricultural sustainability assessment. © 2011 Springer Science+Business Media, LLC.
