STUDIES ON THE EFFECT OF FOAM INDUSTRY EFFLUENT ON Phaseolus vulgaris var. contender.L

Abstract :

The use of industrial waste water in irrigation for crops is a recent phenomenon. A large number of industrial wastes and effluents have been successfully used for irrigation of crops with and without any treatment. The present study has been conducted on the effect of foam industry effluent on percentage seed germination and growth parameters of Phaseolus vulgaris var.contender.L. The untreated foam industry effluent of 25%, 50%, 75% and 100% was given to soil in different experimental sets at regular intervals. The untreated foam industry effluent was diluted with distilled water. The study was also made on the seeds soaked in 100% effluent concentration for 24hrs and 48hrs. A control set with no effluent treatment to soil or seed was maintained for comparison of results. The effects of effluent at various concentrations were studied on percentage seed germination, root length of plants, shoot length of plants, number of leaf appendages, number of nodules per plant, total number of flowers, average pod length, average seed number per pod and percentage of seedless pods. It has been observed that the 25%, 50%, 75% and 100% untreated effluent affected all the parameters. The seed soaked in 100% effluent for 48hrs failed to germinate even on 13th day and on 20th day. Only 3% seed germination was observed but these seedlings could not survive after 8 days. However, in comparison with control set plants, it can be concluded that the foam industry effluent is detrimental for plants at all the above said concentrations i.e. effluent treatment at all the concentrations has induced seed less–ness thereby decreasing the yield. Thus it is concluded that untreated foam industry effluent cannot be diverted towards agricultural nor they can be recommended for the irrigation before properly treated in ETP or CEPT.
