Nanotechnology is a branch of science and promising field for future agriculture. Nanotechnology broadly used to refer both the science and technology of this emerging field. This has significant effect in agriculture and the potentiality for improvement safe environment. Nanotechnology deals with the smallest possible particle which raises hope for developing agricultural industry increases productivity with low input and this is the smart agricultural technology for future. In addition, as the most important source of increasing income, agricultural industry increases the use of this nanotech. At the same time significant challenges must be overcome for the benefits of nanotechnology to be realized. Scientists must learn how to manipulate and characterize. Government has to take responsibility for this concern. Nanotechnology have much more future prospects to enhance agricultural production by making much more advance use of nanopores, zeolotes, nanocapsules, nanosensors, etc. So, the review presents information on the use of application of nanotechnology and the challenges for adopting this new technology with the future aspects in agricultural industry.

Kandelia candel (L.) Druce play an important role in creating habitats for a diverse community of organisms ranging from bacteria and fungi to fishes and mammals. A field experiment was conducted to enrich mangrove ecosystems through establishment and conservation of the mangrove species K. candel (L.) Druce in the moderate saline zone of the Sundarban in Bangladesh during the period of 2012 to 2017. Assessing the performance of K. candel plantations were done annually by monitoring the survival rate and one or more structural characteristics of the stand, including height (H), diameter at breast height (DBH) and mean annual increment (MAI). The height (m), DBH (cm), MAI (m) and survival (%) of K. candel trees differ significantly at different spacing. The highest height (m), dbh (cm) and survival (%) have been found 2.99m±0.09, 3.83cm±0.10 and 90%, respectively in the spacing 2m x 2m as well as the highest mean annual increment (MAI) for height 0.60 m and for dbh 0.77 cm were found in the same spacing. The calculated values were F.05 (2) = 64.60 which was highly significant at the 5% level, LSD = 0.23for height and F.05 (2) = 40.71, LSD = 0.25 for DBH. There were significant differences in the mean total height (m) and mean DBH (cm) among the spacing 2m x 2m, 1.5m x 1.5m and 1m x 1m. On the other hand coefficient of variation (CV) at different spacing was found 9.36, 11.54 and 13.64 for height and 8.62, 4.17 and 10.79 for DBH. All these findings reflect that growth performance of K. candel species was better on 2m x 2m compared to 1.5m x 1.5m and 1m x 1m spacing. Artificial regenerations of K. candel species can improve degraded habitats to facilitate recolonization by native mangrove species. To ensure sustainability of mangroves in the Sundarban, it is necessary to protect all the existing mangrove wetlands under in situ conservation by setting up natural reserves and excluding further anthropogenic destruction as well as developing a long-term scientific program.

Cattle are one of the indexes of civilization, sources of wealth, health and prosperity for nation. Cattle provide us food, cash as well as mechanical power. The production of cattle is low due to their poor genetic makeup, indigenous and large incidence of diseases. Artificial Insemination (AI) is the first generation reproductive biotechnology that has made a profound contribution to the genetic improvement as well as recognized breeding tool of the cattle. But farmers in Bangladesh are not yet able to adopt it perfectly. That was why the principle objective of the study was to determine the correlation of different characters of problems faced by the farmers in adopting AI of cattle. The study was conducted at two villages of Kishoreganj Sadar Upazila in Kishoreganj district. Data were collected from a sample of randomly selected 100 farmers out of 340 farmers. The data were collected through personal interview by using an interview schedule. Pearson’s product moment correlation co-efficient (r) was used to test the concerned null hypothesis in the relationship between the dependent and the independent variables. Except household size, farm size, farming experience and social mobility, the other seven selected characteristics showed significant negative relationships and age showed significant positive relationship with the extent of problems in adopting Artificial Insemination by the farmers.

Jute seed production capacity varied significantly in relation to variety. An experiment was conducted at Jute Research Regional Station, Faridpur at September, 2016 to January, 2017 with five varieties, viz., O-9897, BJRI Tossa Pat 4 (O-72), BJRI Tossa Pat 5 (O-795), BJRI Tossa Pat 6 (O-3820) and JRO-524 to find out the seed production capacity and quality. The result revealed that the highest seed yield was obtained from O-9897 (557.56kg/ha) which were statistically identical with the seed yield of O-795, O-3820 and JRO-524 where as O-72 gave the lowest seed yield. Seed quality was highest at O-3820 with maximum normal seedlings percentage (79.67%) and minimum abnormal seedlings percentage (10.33%). Jute seed yield was significantly positively correlated with plant population. For highest amount of seed production O-9897 cultivation should be recommended and for best quality seed BJRI Tossa Pat 6 may be recommended to cultivate at Faridpur region.

The empowerment of women is a vital issue in developing countries. Women’s empowerment has become a global phenomenon in the contemporary discourse of development. This paper evaluated the impact of microcredit on women’s empowerment in Dinajpur during the period of January to December 2016. The data were collected from 158 women by one to one communication through structured questionnaire for collection the information of non-borrowers women to compare the impact between borrowers and control group from four villages namely; Biral, Birampur, Bochaganj and Parbatipur. A significant outcome of this study showed that microcredit has a positive impact on women empowerment and promotes microcredit borrowers especially women to participate in the household decision-making process through acquiring the self esteem, business skills, confidence level, etc. The results confirmed that microcredit has both significant and positive impact on women’s empowerment.

An experiment was conducted to study the effect of different feeds on growth and production of freshwater Mud Eel (Monopterus cuchia) in nine aquariums over a period of 90 days during June to August 2016. Three different feeds namely Feed A (live feed), Feed B (supplementary feed) and Feed C (probiotics) were applied to treatments I, II and III respectively. Three types of water used in aquarium. These are pond water, ground water and turbid water. Each of the tanks was stocked with nine fish that’s total fish amount of 27. Significantly highest weight gain was obtained in pond water, treatment III, (16.39a ± 2.35). Treatment III yielded the highest (65.56a ±9.4 g/m2 /year) production with the highest survival rate of fish. Water quality parameters like temperature, dissolved oxygen, PH, and alkalinity were optimum. On the basis of better growth and production, it is suggested that pond water condition with probiotics are suitable for the culture of M. cuchia in aquarium.

This study intends to test, analyze, and verify the influence of bank size, capital adequacy, liquidity, credit risk, and market power on commercial banks profitability. Quantitative research methods applied in this study are explanatory method, which aims to analyze the influence of independent variables on dependent variable and descriptive method to describe the object studied. The study also applies Stochastic Frontier Analysis (SFA) approach to estimate the technical efficiency of commercial banks. The results show that bank size, capital adequacy (CAR), liquidity (LDR), credit risk (NPL) and market power significantly affect the profitability of commercial banks in Indonesia in the period of 2010-2016.The result of yearly financial report of each bank is caused by the fact that: 1). some banks are in the process of mergers; 2). the allowance for impairment losses on financial assets and non-financial assets increased primarily with banks in the merger process; 3). banks have credits in default status and under special surveillance with an increasing amount of credits from year to year.
