Abstract
The physico-chemical characteristics of paper mill industry effluent were measured and some were found to be
above the permissible limits prescribed by Indian irrigation water standard. A study was conducted in pots to
investigate the effects of different concentrations (10, 20, 30, 40, 50, 60, 70, 80 and 100%) of paper mill effluent
on growth and production of rice, mustard and pea for three years. The study reveals that the paper mill effluent
has deleterious effect on the growth of crop at higher concentrations. However, at lower concentration (viz. 10 to
40% in rice, 10 to 50% in mustard and 10 to 60% in pea) of effluent, beneficial impact on general welfare of the
crops was noticed. Growth and development was increased with increasing the concentration of the effluent up
to 30% in rice, 40% in mustard and 50% in pea. Investigation showed that the growth and production of rice,
mustard and pea was found maximum at a concentration of 30, 40 and 50% effluent respectively.
