3.1 General Plant Growth in Endosulfan
Sulfate-Contaminated Soil In non-spiked control soil, all the plants grew normally
either alone or in combination for 60 days. The growth of sweet corn, cucumber, and cowpea grown in endosulfan
sulfate-contaminated soil varied depending on plant species and planting regime. Sweet corn or cowpea,
when grown alone or together with another plant in endosulfan sulfate-spiked soils, appeared healthy and
did not show any signs of stress during the 60-day experimental period. Interestingly, the shoot of sweet
corn was longer when the plant was grown together with cucumber or cowpea especially on day 60. The shoot of
cowpea grown in non-spiked soils was not significantly together with another plant.On the basis of general plant
growth alone, sweet corn and cowpea seemed to be more s u i t a b l e than cucumber f o r use in
phytoremediation of endosulfan sulfate-contaminated soils. different from that grown in endosulfan sulfate-spikedsoils during the 60-day experiment. In contrast to sweet corn or cowpea, cucumber exhibited poor growth in
endosulfan sulfate-spiked soils and the plant died between 50 and 55 days of transplantation when grown
either alone or together with another plant. The leaves of cucumber grown in spiked soils exhibited chlorosis and
wilted. Also, the shoot of cucumber appeared short and stunted when the plant was cultivated either alone or
