The tannery effluents contain a high concentration of chromium (Cr). It drastically reduces the crop
yield when used for irrigation purpose. A huge volume
of tannery effluents is available as irrigation for crop
production. It is negatively affecting germination as well
as yield of the crop. The wheat seeds were exposed to
five different concentrations of Cr (0, 20, 40, 80, and
100 ppm). In Petri plates, 100 seeds were placed and the
germination percent was recorded after 72 hour (h).
Root elongation and coleoptile growth were measured
at 72, 120, 168, and 240 h. Results showed that the
germination percent of the test crop decreased with
increasing Cr levels. It decreased by 6, 14, 30, and
37 % under the Cr concentration of 20, 40, 80, and
100 ppm, respectively. The root elongation was more
sensitive than the coleoptile growth. The negative correlation was found between Cr levels and root elongation as well as coleoptile growth. These growth parameters were significantly affected up to 80 ppm of Cr
level. The wheat growers using tannery effluent as irrigation should be well treated prior to application.
