| Abstract | Red Amaranthus (Amaranthus gangeticus. L), a common and popular leafy vegetables in Bangladesh. Nutrient availability is indispensable for better performance of crop productivity, which generally comes from soil. Supplementary addition of fertilizers is needed when the nutrient availability is low. The present study was conducted in pots with the view to explore the potential of industrial effluent as a source of nutrients for agricultural use against its heavy metal contents and uptake patterns by plants. The study was executed in the randomized complete block design comprising the five combinations of different proportion of N to be supplied using urea and Effluent, and a control (with no N fertilizers). Red amaranth was harvested at 30 DAS and 42 DAS. Soil effluent and Plant samples of root, stem and leaves were analyzed to determine their nutrient and heavy metals. The fresh and dry matter production was also considered as the crop yield. Soils contaminated with industrial effluent (SE) was not comparable in terms of it's nutrient content with that of other fertilizers since it contained low to medium level of nitrogen, phosphorous, and potassium. However in this experiment, result suggest that SE had a little influenced on fresh yield production as well as N, P, and K uptake and distribution. On the other hand SE had a significant influenced on heavy metal uptake and distribution although the data were below the maximum acceptable level for red amaranth (50-mg kg-1 Pb, 7-mg kg-1 Cd) as specified by the United States Environmental Agency. Zn and Cu were metals of most concern since it was present in high levels. There was no immediate benefit SEN for red amaranth because of slow release of nutrients by SE and short-term fast growth habit of red amaranth. |
