This study aims to present a comprehensive review of bioethanol, its prospects, and also to estimate a potential source for commercial bioethanol production in Bangladesh. In Bangladesh, the primary source of fuel comes from natural gas and petroleum oil. But the total output of fossil fuel is incapable of meeting the annual fuel demand. And also, the natural reserves are insufficient to meet the energy demand for long-term economic development. To meet the demand every year Bangladesh needs to import a huge amount of petroleum oil from overseas markets. In this situation, to manage the future demand, production of renewable energy may be an alternative solution. Bioethanol production from potato and potato peel waste maybe a prospective source of renewable energy. It can use as an alternative clean-burning fuel by replacing with regular vehicle fuel. It can not only save huge foreign currency but also lessen greenhouse effect in the environment. In this scenario, there is a huge prospect to introduce bioethanol as an alternative fuel in Bangladesh.

Purpose The research was performed to assess the effect of vermicompost and tuber size on the storage behavior of potato during the ambient condition.

Aims: The experiment was conducted to assess the effect of vermicompost and tuber size on processing quality of potato during ambient storage condition. Study design: Experiment was conducted in a split-plot design, where vermicompost levels were assigned to main plots and tuber size to subplots.

Maintaining exportable standard of potato is the main bottleneck for the Bangladeshi potato growers and exporters. Bangladesh producing large amount of potato which may give much contribution in world market in future especially in European countries. But, yield and quality of potato is varying with some factors i.e., abiotic, biotic, varietal and nutritional, respectively. From these perspectives, the study was carried out under pot experiment at two consecutive years with due, that; applied chloride may influence the performance of tuber in major salt affected areas where the people wants to grow potato in their field. The experiment consisted of four salt application doses (N 0 = non-saline, N 1 = 5, N 2 = 15 and N 3 = 25g NaCl pot-1) and three varieties (V 1 = Granula, V 2 = Lady Rosetta and V 3 = Asterix). The pot was arranged following completely randomized design (CRD) with 3 replications. Result revealed that; yield, dry matter and specific gravity were decreased with the increasing of salinity levels. Results demonstrated that, non-saline condition of pot soil is favorable for getting the maximum return from studied parameters. Granula and Lady Rosetta performed the significant similar results in case of studied parameters. Although, Granula showed highest specific gravity at 5g NaCl plot-1 which was statistically similar to non-saline condition but, Granula exhibited the highest yield and dry matter under non-saline condition of pot soil. Similar trend was also found in case of Lady Rosetta whereas Asterix performed worst one under highest condition of soil salinity. In, conclusion, it may be said that; potato has sensitivity on salinity for its performances, so, the salt tolerance/salt avoidance varieties should be introduced/developed in our country and the further research should be carried out with how much amount of EC of salinity can be tolerated by exportable potato varieties.

Sesame is an important oilseed crop due to its different types of commercial application. The produced oil from sesame uses for food and beauty care product preparation due to its high nutritive value. However, the yield of sesame is comparatively low than other oilseed crops. Nitrogen and Boron are essential nutrients for plant development and growth. So, the combined application of nitrogen and boron can increase the yield of sesame. From these perspectives, an experiment was carried out to study the effect of nitrogen and boron application on yield contributing characters and yield of sesame. The experiment consisted of four Nitrogen doses (N0: 0 kg N/ha (control), N1: 50 kg N/ha, N2: 60 kg N/ha, N3: 70 kg N/ha) and three Boron doses (B0: 0 kg B/ha (control), B1: 2 kg B/ha, B2: 3 kg B/ha). It was laid out in two factors Randomized Complete Block Design (RCBD) with three replications. Result demonstrated that combination of 60 kg N/ha and 3.0 kg B/ha were acceptable for getting better yield and maximum economic return from the studied parameters.
