Water samples were collected from the Rupsha river of Khulna region to determine ionic contamination for irrigation purpose. The chemical analyses included pH, EC, TDS and ions. pH values of water samples were slightly alkaline in nature. Samples were rated as fresh water based on TDS values. Samples were high salinity and low alkalinity hazards expressing C3S1. Regarding SAR and SSP values, samples were excellent and good classes, respectively. Samples were free from RSC and were very hard class. Regarding PI values, samples were under class-II implying 75% maximum soil permeability. Ca, Mg, Na, Cu, Ni, Zn, HCO3, SO4 and PO4 levels in samples were within safe limit. Cd, Cr and Cl ions in water samples were above the permissible limit and were treated as water contaminants for irrigation. From the present findings, it is noted that the detected ions as water contaminants should be considered for irrigation usage toward food safety. J. Environ. Sci. & Natural Resources, 11(1-2): 145-151 2018

Adoption of organic farming has been increased which have a reduced impact on environment. An experiment was conducted at the Landscaping section and Laboratory of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh for optimisation of growth, yield and quality of strawberry cultivars through organic farming during the period from October 2017 to March 2018. The experiment comprised two cultivars viz., RU-1 (Festival) and RU-2 (AOG), and eight organic manures viz., control, cowdung, mustard oilcake (MOC), poultry manure, cowdung+MOC, cowdung+poultry manure, MOC+poultry manure, cowdung+MOC+poultry manure. The two-factor experiment was laid out in randomised complete block design with three replications. Significant variation was observed between strawberry cultivars and organic manures in all the parameters studied. Highest growth, yield and quality characters were obtained from Festival except number of runner per plant and TSS content with AOG. Combined application of cowdung+MOC+poultry manure gave the maximum yield (19.14 t/ha) than the other treatments. J. Environ. Sci. & Natural Resources, 11(1-2): 121-129 2018

Cadmium (Cd) is a heavy metal which is not essential for human body. Cadmium enters into human body mainly through food consumption. Besides industrial wastes, phosphate fertilizers contain Cd which accumulates gradually in agricultural lands. To produce high quantity of food for about 160 million people of Bangladesh, agricultural lands need to be applied huge amount of fertilizes including TSP which add Cd to soils. It has been reported that in rice grains the cadmium concentrations were the highest in Bangladesh and Srilanka where the per capita rice intake is high, from a survey on four continents of 12 countries. The intake of these Cd containing foods may ultimately increase the Cd concentration in human kidneys and livers which might be related to the enhanced kidney patients in Bangladesh. There is lot of toxic effects of excess Cd on humans. The present review illustrates the urgency of further studies of Cd in Bangladesh. J. Environ. Sci. & Natural Resources, 11(1-2): 227-234 2018

Tangail district has undergone dramatic changes in its physical form through urbanization. Here, agricultural land and vegetation cover have been transformed into built-up areas; fallow land and water bodies into reclaimed built-up areas. The aim of this research was to develop land use and land cover (LULC) maps of the Tangail Municipality area in 2001, 2011 and 2017. Landsat (TM) Satellite images of the year 2001, 2011, and 2017 were used. On-screen digitization method was applied to prepare the final maps with four classes (water bodies, vegetation, agricultural land, and settlement area) of land use. The study reveals that the settlement area was increasing over the study period, and mainly agricultural land and water body were converted into settlement. It was found that about 48.73% areas were covered with the settlement area in 2017. Similarly, a substantial increase was seen in the areas of vegetation as about 824.49 ha land added to this category throughout the study years. In contrast, the agricultural land (786.30 ha) and water body (114.73 ha) were declined between 2001 and 2017. J. Environ. Sci. & Natural Resources, 11(1-2): 245-252 2018

The effect of Amistar in controlling Alternaria blight of mustard was investigated and the selected mustard variety Rai- 5 was used. Amistar @ 0.05% (1 spray), 0.05% (2 spray), 0.05% (3 spray), 0.1% (1 spray), 0.1% (2 spray) and 0.1% (3 spray) were sprayed at 14 days interval beginning from 40 days after sowing (DAS). Amistar resulted significant reduction of the disease Alternaria blight (Alternaria brassicae and Alternaria brassicicola) severity and increased seed yield. Out of the doses of Amistar used, 0.1% (3 spray) showed marked effect in reducing the disease over control in terms of reduction of % Alternaria blight incidence, % leaf infection and % leaf area diseased up to 90.72%, 90.42% and 98.17%, respectively as well as reduction of % siliqua infection and % area of siliqua diseased up to 96.17% and 98.80%, respectively and thus increased seed yield up to 56.47% over control.

The present study was conducted to carry out a comparative study on farm materials (water, soil, feed) and the quality parameters of pangus (Pangasianodon hypophthalamus) of five different farms in Trishal area under Mymensingh district. The study was carried out during May-June, 2016. Most of the pangus farmers used homemade or farm made supplementary feeds for pangus culture The percent moisture, protein, lipid and ash content in fresh fish ranged from 77.05 to 78.79, 14.21 to14.84, 3.55 to 4.49 and 2.03 to 2.67 whereas after 24 hrs of death of fishes, these percent values changed as 77.05 to 78.79, 14.21 to14.84, 3.55 to 4.49 and 2.03 to 2.67. Slight changes observed in different quality parameters in the fish samples 24 hrs after death as dead fishes were preserved at chilling temperature in a homestead refrigerator till analysis. Therefore, the study could be concluded that- though the values for different parameters of farm materials (water, soil, feed) and quality parameters of fish samples differed but was mostly not significant. The differences observed in the parameters might be due to the variations in management techniques of each farm. J. Environ. Sci. & Natural Resources, 11(1-2): 109-119 2018

The experiment was conducted at Cotton Research, Training and Seed Multiplication Farm, Jagodishpur, Chowgacha, Jessore initiated June 19, 2015 for the cropping season 2015-16 to observe the performance of cotton based cropping system including total three crops in a year. The other crops were i) relay wheat – mungbean and ii) relay lentil – mungbean. Four cotton varieties CB-12, CB-13, CB-14 and CB Hybrid-1 were sowed in a RCBD design with three replications. Seed cotton yield was significantly different among the varieties. The highest seed cotton yield (2519.3 kg/ha) was obtained from CB Hybrid-1 and the lowest (2112.37 kg/ha) seed cotton was produced by CB-13. The highest BCR (1.31) was observed in cotton (CB Hybrid-1) –relay lentil –mungbean cropping pattern and the lowest BCR (1.10) was observed in Cotton (CB-13) – relay wheat –mungbean cropping pattern. The finding infers that cotton – relay lentil - mungbean cropping pattern might have the potentiality to increase cropping intensity in Bangladesh. J. Environ.

Rice bran, a milling byproduct of rice is rich in nutrients especially high in fiber and protein in comparison with white wheat flour-which is predominantly used for bread production. Inclusion of rice bran with wheat flour was expected to induce nutritional value of bread positively. Two form of rice bran sample both full fatted and defatted were incorporated with wheat flour in a proportion of 0%, 5%, 10% and 15% respectively to develop composite bread. Physical, chemical, and sensory evaluation was carried out to determine the quality of different composite breads. Bread weight didn’t differ statistically though there was a marginal declination of volume for bread with the increase of the percentage of rice bran. The percentage of protein and fiber was increased rationally as expected. A level of 10% rice bran added to bread was regarded to yield good sensory quality. J. Environ.

The study has been carried out in a Riverine Island of the Ganges River in Chapai Nawabganj District of Bangladesh to evaluate the livelihood status and the association between different livelihood capitals and well-being status. Both qualitative and quantitative data are collected through household questionnaire survey and field observation. Most of the surveyed households are found either poor or hard core poor. This study identified five capitals of livelihood i.e. human, social, natural, financial and physical capitals with specific indicators. Family size and education indicators of human capital, organizational attachment of social capital, total and operational land of natural capital, value of livestock, size of savings and loan of financial capital and mobile phone of physical capital are statistically significant with the well-being status. This means higher value of indicators indicate higher the well-being status. Hence, this study assumes that most of the char dwellers are poor or hard core poor because their livelihood capitals and assets are not in satisfactory level. This study suggests providing necessary institutional and organizational supports for strengthening the livelihood of char dwellers. J. Environ. Sci. & Natural Resources, 11(1-2): 27-36 2018

The study investigated physicochemical parameters and heavy metal concentrations in water of the Mokesh beel during January to June 2016. Samples were collected from 3 different locations and analyzed in the laboratory of the Department of Environmental Science and Resource Management, MBSTU, Tangail and BINA, Mymensingh. Results showed that EC and TDS were varied from 645-688μS/cm and 541-586mg/l, respectively indicated high ionic concentration, whereas DO of all stations ranged from 4.1-5.5mg/l represents low organic waste, and pH (7.25-7.55) of all stations showed alkaline nature. In case of heavy metal concentration Pb, Cd, Cu, Zn and Cr were within the standard level. The result concludes that the water can be used for different purposes but heavy metals can be accumulated in fish flesh, consequently affect the human health. To maintain the water quality and conserve the aquatic life, proper measures should be taken to prevent pollutants intrusion into the beel. J. Environ. Sci. & Natural Resources, 11(1-2): 1-8 2018
