An experiment was conducted at the Multi location Testing (MLT) site, (medium highland under AEZ-25) Pachbibi, Joypurhat, Bogura district during rabi season of 2015-16. In the study, to evaluate the response of panikachu to different nutrient management practices under farmer’s field condition. There were five treatments viz. T1=Soil test based fertilizer dose (FRG 2012), T2=T1+ 25% NPK, T3=IPNS with 3 tha-1 poultry manure, T4= IPNS with 5 tha-1 cowdung, and T5= Farmers practice. The experiment was laid out in randomized complete block design (RCBD) with six dispersed replications.T3= IPNS with 3 t ha-1 poultry manure, T4 = IPNS with 5 t ha-1 cowdung, and T5= Farmers practice. The highest Panikachu rhizome yield (21.71 t ha-1), gross return (TK. 430185ha-1) and BCR (3.61) were found from T3 (IPNS with 3 t ha-1 poultry manure) which was followed by T5 (19.66 tha-1) T4 (19.45 tha-1), and statistically differed to other treatments. However, from results, it could be recommended that IPNS will be a promising technology for higher crop yields of Panikachu and profit as well as for the improvement of soil fertility and sustain soil productivity in Joypurhat region.

Nga-pi, an ethnic fermented product traditionally produced at Cox’s Bazar region by Rakhine people is one of the popular food items of that area. To assess the quality of raw shrimp used for Nga-pi production and traditionally produced Nga-pi were collected. Some amount of the collected Nga-pi sample (from producers of both areas) were stored at refrigeration temperature (5 to 8°C) for 90 days to observe the changes in nutritive values, TVB-N and SPC during the storage. The results of proximate composition analysis for the samples showed that-the moisture content ranged from 58.29% to 61.06%, the crude protein content ranged from 25.88% to 27,12%, the crude lipid content ranged from 4.18% to 5.12% and ash content ranged from 7.30% to 8.40%. On the other hand the range for TVB-N value was found from 25.06 mg/100g to 34.02 mg/100g and SPC value from 1.69×105 CFU/g to 4.27x 106in Nga-pi samples. The result of the Nga-pi sample stored in air-tight polythene pack at refrigeration temperature (5 to 8°C) for 90 days showed thatthe percent moisture, percent ash content, TVB-N value and SPC value increased but the percent protein and lipid content decreased with the progress of storage time.

Widespread groundwater arsenic contamination in south, south-western and north-eastern regions and high salinity in the south-western coastal region are the two major challenges for drinking water supply in Bangladesh. In this study, we assessed various water supply technologies used for mitigating arsenic and salinity in Laksam of Cumilla and Assasuni of Satkhira district. Water samples were analyzed for Arsenic, Iron, Chloride (indicator for salinity) and FC from different water extraction systems (shallow, deep and Tara tubewells), groundwater arsenic treatment units (SIDKO and READ-F), rainwater harvesting systems (RWH), pond sand filters (PSF), and managed aquifer recharge units. Most shallow tubewells, both in Laksam and Assasuni, have been found to produce arsenic contaminated water. But water from deep and Tara tubewells have been found arsenic-free, though high concentration of iron was observed in the wells in Laksam. Rainwater harvesting systems, PSF and MAR units in Assasuni have been found to provide water free from the common chemical contaminants but suffer from high bacterial contamination. Deep tubewell appear to be the most preferred option where a suitable aquifer is available. The community-scale groundwater treatment systems would require strong operation and maintenance support from the service providers to be successful.

An attempt was made to evaluate the contamination status of surface water collected from the Balu river for irrigation. Twenty samples were collected to analyze pH, EC, TDS and ions. Samples were slightly alkaline in nature. Water samples were from low to medium salinity and low alkalinity hazards (C1S1-C2S1). As per TDS values, samples were classified as freshwater. Considering SAR and SSP values, samples were excellent and good to permissible classes, respectively. Most of the water samples were free from RSC and all the samples were under moderately hard. The status of Cr and Mn ions in samples surpassed FAO guideline values indicating contaminants for long-term irrigation. The levels of other metal ions in samples were within acceptable levels and did not pose a threat to irrigated soil. This finding revealed that Cr and Mn ions were considered as contaminants in river water for irrigation posing harmful impact on soils and crops.

Twenty-two genotypes of maize parental line were grown during 2017-2018 at the Research field of Plant Breeding Division, Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Rahmatpur, Barisal, Bangladesh. The experiment was laid out in randomized complete block design with three replications. Heritabilty, coefficients of variability and genetic advance values were computed for days to tasseling, days to silking, days to maturity, plant height (cm), ear height (cm), cob length (cm) and diameter (cm), number of seed rows per cob, number of seeds per row, number of seeds per cob, thousand grain weight (g) and yield (g/plant). Among all the traits higher phenotypic coefficient of variation (44.53) and genotypic coefficient of variation (44.18) were observed for yield/plant. The uppermost heritability was observed in case of yield per plant (98.41) followed by 1000 seed weight (96.91). Genetic advance was highest for seeds/cob (197.87) followed by 1000-kernel weight (176.86).Greater magnitude of heritability coupled with higher genetic advance in characters under study provided the evidence that these plant parameters were under the control of additive genetic effects. Indicating that selection should lead to a fast genetic improvement of the material.

The research was conducted to collect information on the status of farming and marketing of live pangas (Pangasius hypophthalmus) from Trishal region to different areas of Bangladesh by interviewing stakeholder and secondary sources. The survey was carried out for seven months from May to November, 2016. Pangas farmers, arotdar, commission agents, wholesaler and retailers were interviewed in accordance with participatory rural methods. The results showed that the best harvesting season were found to be June to July and November to January. It was also found that 90% farmers harvested their fish completely and only 10% of farmers harvested partially. The price of pangas depends on market structure, quality, size, distance, weight, seasonal variation and regional perception. The prices of pangas were found to be highest of 130tk/kg and the lowest of 85tk/kg but sometimes 60 to 70tk/kg when the fish are dead (on the way to destined area) in different districts. On the other hand significant quantity loss was observed in fish 8%, 10%, 15%, 18%, and 19% after reaching to Savar, Manikgonj, Maowa, Sylhet, and Barisal from Trishal. Therefore, it was strongly recommended that proper handling of live fish must be ensured during transportation to attain quality pangas at consumer level.

Development was conventionally driven by one particular need, without fully considering the wider or future impacts. This kind of approach has now been considered to be responsible for the economic and environmental catastrophes that humans are facing: from large scale financial crises caused by irresponsible banking to the changes in global climate resulting from our dependence on fossil fuel based energy sources. Soils provide essential ecosystem services such as primary production, regulation of biogeochemical cycles (with consequences for the climate), water filtration, resistance to diseases and pests, and regulation of above-ground biodiversity. Changing of the climate systems is unequivocal. Adaptation to global climate change through improved soil quality by adoption of improved management practices is key to maintaining sustainable agricultural production. A holistic approach to soil management as the engine for increasing productivity by increasing resource use efficiency and making agriculture environmentally compatible is more important than ever before. Strategies of greenhouse gas emission reduction include those that increase the use efficiency of inputs. Herein, we discussed how management and protection of soil resources can contribute to sustainable development through sustainable agricultural production while maintaining sustenance of soil fertility.

Textile dyeing effluent is considered as one of the most environmentally unfriendly industrial processes. The study aimed to review the different types of textile dyes use in the industrial processes and their contribution to environmental pollution in South Asian countries. The article was prepared to compile all present data from different journals and website on textile dyeing effluents characterization in South Asia. A wide variety of synthetic dyes like azo dye, vat, reactive dye, disperse dye, etc. widely used in the textile sector. The result showed that some physicochemical parameters of the dyeing effluents (COD, TDS and BOD) exceeded their standard limits. The industrial effluents are affecting the main devastation to the aquaculture, agriculture, ecology, environment, and public health since the development of textile dyeing industries in these countries. Now a day, its proper supervision and curative measures like removal system have become the furthermost thoughtful tasks all over the world and the developing and transition economies countries in particular. It is imperative to take immediate steps to reduce the environmental pollution due to discharge the untreated textile dye effluents. J. Environ. Sci. & Natural Resources, 11(1-2): 131-144 2018

Impact identification is the first step in an Environmental Impact Assessment (EIA) process, contributing to prediction, evaluation and mitigation of significant environmental impacts. It connects the project characteristics to baseline environmental information with the aim of ensuring that all significant impacts are taken into consideration. The study location was at Dacope Upazila of Khulna District in Bangladesh. A Liquefied Petroleum Gas (LPG) bottling and distribution plant is going to set up by Energypac Power Generation Limited. The objective of the study was to identify the impacts on the major environmental components of the study area. The field observation, interviews of project proponent and community people, public consultation, laboratory analysis were the main activities of the study along with others. This study has done an appropriate analysis of baseline condition of the major environmental components of the study area, identified the impacts of the project on major environmental components and developed an environmental management plan for the LPG bottling and distribution plant.
