Abstract

Effect of paper mill waste-water irrigation on crop growth, nodulation and VA mycorrhizal colonization was assessed by growing mungbean [Vigna radiato (L..) Wilczek] and maize (Zea mays L.) in pot soil collected from a field with five year history of Mandhiali Paper Mill effluent irrigation. situated 20 km from Lahore on Lahore-Sheikhupura Road. Plants of both the test species were also sown in normal field soil as control. Shoot growth in both the test species was adversely affected in paper mill effluents contaminated soil (PMCS). The difference between the two treatments was significant (P=0.05) in maize. Pod number in mungbeat was significantly reduced in PMCS as compared to control. Effect of PMCS on nodulation in mungbean and root growth in both the test species was insignificant. Extent of VAM infection was severely arrested showing significant reduction (P=0.01) in maize in PMCS However, there was not any significant difference in VAM colonization between the two treatments in mungbean.
