Abstract:
Effluent samples
were collected from Koh-e-Noor textile mill, Marble Industry and Attock
oil Refinery for present study. Different dilutions (0, 10, 20, 40, 60,
80 and 100%) were used to irrigate two varieties of lentil (M-93 &
NARC-02-4). Koh-e-noor (textile) mill effluent was most injurious as its
all concentrations caused a reduction in the length parameters of the
two varieties. Roots were more affected than shoots. Whereas various
concentrations of effluents from marble industry and refinery were
stimulatory for the growth of both varieties. General growth of Lens
esculentum var NARC-02-4 under normal conditions was better as
compared to var M-93 but the percentage reduction in length parameters
was less in case of M-93 as compared to NARC-02-4. Comparison of the two
varieties showed that the overall fresh and dry weight of seedlings was
more in case of M-93 as compared to NARC-02-4. The dry mater
accumulation was comparable in the two varieties. Study concluded that
effluents from Marble industry and Refinery could be used for irrigation
purpose after dilutions as was evident from the length and weight
parameter. The growth of both varieties of lentil was suppressed in
textile effluent, but both could be grown in the other two effluents in
variable concentrations for optimal growth.
