A field experiment was conducted to evaluate the different brands of zinc fertilizer produced and marketed in different areas of Bangladesh and their effect on nutrients content in rice (BRRI dhan 32). Among the nutrients; the content of N, S and Ca in grains and straw did not vary significantly, but the contents of P, K, Na, Mg, Zn, Cu, Fe and Mn in grain and straw varied significantly due to ...

Soil heavy metals have been a very useful indicator of environmental quality worldwide. The present study was conducted to investigate the levels, sources, distribution and spatial variability of heavy metals (Cu, Mn, Cd, Pb, and Zn) in soils in close proximity to an industrial area. Hierarchical Cluster Analysis (HCA) was applied to test the similarities between sampled elements based on neare...

diagnosis and recommendation integrated system (dris) can be used as efficient methods to interpret the results of plant analysis and the nutritional diagnosis in crops and fruit trees. to establish dris norms in onion (allium cepa l) leaf samples were collected from 50 fields and n, p, k, ca, mg, fe, mn, zn, cu and b concentrations were determined. on the bases of yield, the studied fields wer...

abstract pistachio ( pistacia vera l.) is an important crop in our country and has a unique position in export goods. in respect to better nut quality this research was conducted during 2005-2006. macro and micronutrients were used as foliar application to surmount soil limitations in nutrient uptake and alternate bearing control with “owhadi” cultivar in rcbd with 3 replications. the treatment...

Phenobarbital and clofibrate, two non-genotoxic carcinogens, have been investigated regarding the relationship between reactive oxygen species, antioxidant enzyme expression and apoptosis in primary cultures of rat hepatocytes. Low toxicity concentrations, 200 and 100 microg/ml for phenobarbital and clofibrate respectively, were used to examine their effect on spontaneous or transforming growth...

pollution of water and soils by heavy metals is an emerging problem in industrialized countries.the present study was conducted to investigate the heavy metals concentration in water and sedimentsamples from ship breaking sites of sitakunda to assess the potential ecological risk posed by heavy metalusing different methods. heavy metals concentration was analyzed by atomic absorption spectrosco...

in the present investigation flocculation of dissolved cu, zn, pb, ni and mn in a series of mixtures with salinities ranging from 1.5 to 9.5% during mixing of talar river water with the caspian sea water was studied. the flocculation trend of zn (87.22%) >mn (45.31%) >pb (39.09%) >cu (36.58%)>ni (12.70%) indicates that cu, zn, pb and mn have non-conservative behavior and ni has relatively conse...

the concentrations of some heavy metals in sediment from the sinop coasts of the black sea were measured to monitor metal pollution in 2013. the distribution of the heavy metals in sediments of the black sea shows a variable pattern. the objectives of the present study were to elucidate the distribution heavy metals such as cu, pb, zn, ni, mn, fe, as, cd, cr, hg and co in sediment from sinop co...
