Drought effects on the water relations of four wheat (Triticum aestivum L.) cultivars were evaluated. Four cultivars, Kanchan, Sonalika, Kalyansona, and C306, grown in pots subjected to levels stress at vegetative or anthesis stages both. Exposure plants drought led noticeable decreases leaf potential relative content with a concurrent increase temperature. The higher as well lower temperature associated photosynthetic rate. stressed displayed canopy than well-watered both growth stages....

SUMMARY Conservation agriculture (CA) is inadequately developed for rice-based cropping systems widely practiced in Bangladesh. The current drawback the implementation of CA all crops including rice ( Oryza sativa L., ecotype ‘transplanted aman’ [T. aman]) to increase rice–wheat Triticum aestivum L.) rotation productivity. It important identify best combination tillage types and achieve a high yield component improve soil health. Three practices, assigned main experimental plots [namely,...

The study was conducted to investigate the effects of solid waste and industrial effluents on water quality Turag River. Both upstream downstream sampled from selected points were analyzed for color, odor, pH, electrical conductivity (EC), total dissolved solids (TDS), oxygen (DO), biological demand (BOD), copper (Cu), cadmium (Cd), iron (Fe), lead (Pb) zinc (Zn) concentrations. Results showed that color light dark black emitted noxious smell due effluents. slightly alkaline with...

The Sundarbans, located in Bangladesh, is the world's largest mangrove forest with a rich and diverse microbial community. main objective of this study was to use 16S rRNA sequencing identify bacterial community Sundarban forest, particularly pathogenic bacteria aquatic organisms. This conducted Bangladesh collected 225 samples soil, water, fish, shellfish from five locations typical environment. All underwent genomic DNA extraction, quantification, gel documentation, subsequent sequencing....

The study was conducted to investigate the iron (Fe) contamination in groundwater at Tangail municipality during period from January June 2011. Groundwater samples were collected 18 locations, where 15 tube-wells, 2 deep tube-wells and 1 pump. result of showed that highest level Fe (24.50 mg/l) found Dewla north, while lowest (1.03 recorded Bepari para. amount ward 4, respectively. results compared with Bangladesh drinking water quality standards as well international standards. In...

The study was conducted to investigate the heavy metal contamination in water, sediment and fishes from Passur river Mongla port area near Sundarbans mangrove during period January June 2013. water samples were collected five different sampling stations as St-1 (upstream- 1km upper area), St-2 (port St-3 (downstream-1km lower St-4 (tributary) St-5 (1 km tributary). Sediment monthly Station-1, 2 3 period. concentrations of metals (Cu, Zn, Fe Cr) found much than permissible level. (Cr, Cu, Ni,...

A temperature controlled pavement has a significant requirement for preventing road from freezing, and avoiding winter traffic accidents at specific places. For example, slip accident tunnel mouth frequently occurs in causes serious danger human life heavy jam. Horizontal U-Tube (HUT) heating system was introduced order to prevent associated with freezing the west side of Nanaori-Toge tunnel, Aizu-bange, Fukushima Prefecture Japan. group U-tubes were buried depth 1.2 m ground central part...

Rice farmers’ investment on irrigation alone accounts the lion's share of total production cost. Alternate wetting & drying (AWD) method has emerged as a new technique in Bangladesh water saving technique. A study was undertaken with view to verify differences delivery, energy consumption and relative economics AWD conventional practice. Data were generated through sample survey three environments namely Kustia, Rangpur Feni where field experiments conducted validate method. using...

The study was conducted to investigate the heavy metal contamination in fishes and shrimps from Passur River near world famous Sundarban mangroves located southwestern part of Bangladesh, during period January June 2013. fish (Liza parse) shrimp (Penaeus monodon) samples were collected two stations as St-1 (Katakhali-1 km upper port area- upstream) St-2 (Amtola-1 lower downstream) monthly for three months (winter), March (pre monsoon) May (Monsoon). Before analysis, a bit muscle, whole liver...

The study was conducted to asses the aquatic faunal diversity in Ratargul Swamp Forest during period from November 2014 October 2015. For systematic of fauna, quadrate method along with transect used where 4 transects were selected swamp forest each 5 stations based on topography and vegetation. A total 24 species fauna belonging 18 families identified period, which crustaceans (7), molluscs (4), fishes (12) annelid (1). Among them, most dominant abundant groups. crustaceans, molluscs, shown...

The results of a comprehensive three‐dimensional dynamic analysis structurally asymmetric high‐rise buildings subjected to stochastic wind forces are summarized. Random vibration theory is used obtain the response statistics that important for checking serviceability building. Surface pressures measured in wind‐tunnel tests analyzed determine spectra and cross among force components. effects on building eccentricities centers rigidity and/or mass' correlation components examined. A simple...

A socio-economic study was carried out in two rice production environments (Gazipur and Tangail) to assess the comparative advantages of using urea super granule (USG) over prilled (PU) modern examine differences producers’ technical efficiency between USG user non- crop management. Stochastic frontier model employed farm specific difference management PU users areas. Analysis revealed that comparatively low amount (36%) needed boro instead PU. Nearly 366 % more labour plots compared plots,...

The purpose of this study is to monitor the present status water supply and sanitation facilities primary school in Gaibandha Sadar, Bangladesh. Forty nine (49) schools were selected for purpose. revealed that, about 86% had shallow tube well as a source their drinking sanitation. About 18% no facility or inactive unit. Separate toilet girls teachers was found 69 55% respectively but only one has separate male female teacher. Availability water, soap hand washing inside boys latrine average...

Field trials were carried out at the Farming System Research & Development site, Hatgavindapur, Faridpur, On-Farm Division of Bangladesh Agricultural Institute during rabi seasons 2006-2007 and 2007-2008 with objectives to evaluate response lentil Rhizobium biofertilizer reduce use N-fertilizer under farmer’s field condition. The experiment was laid in Randomized Complete Block Design (RCBD) four replications. Unit plot size 4 m x 5 m. Four fertilizer treatments viz. T1: 24-22-42-20-5 kg...

Piedmont lands in Bangladesh, India, Nepal, and many other Asian countries are important rice-growing soils, but most of the soils potentially phosphorus (P) deficient because low pH. Phosphorus fractions acidic piedmont were determined. Soil samples amended with 100 200 mg P kg−1 soil, a control soil without amendment was maintained. The analyzed for following fractions: solution P, labile pool [sodium bicarbonate (NaHCO3) P], alkali-extracted inorganic hydroxide (NaOH) Pi], organic (NaOH...

Cadmium (Cd) is a heavy metal which not essential for human body. enters into body mainly through food consumption. Besides industrial wastes, phosphate fertilizers contain Cd accumulates gradually in agricultural lands. To produce high quantity of about 160 million people Bangladesh, lands need to be applied huge amount fertilizes including TSP add soils. It has been reported that rice grains the cadmium concentrations were highest Bangladesh and Srilanka where per capita intake high, from...
