application of sewage sludge has been a worldwide agricultural practice for
many years. The present study aimed to investigate the effects of sewage
sludge (Ss) has on the physiological parameters of maize (Zea mays L cvs.
PR37NO1). 2 g dm-3 and 4 g dm-3 of sewage sludge were
examined in hydroponic experiment. Some metal contents (Al, Cr, Mn, Na, Zn)
in the shoots and roots of maize were taken. Living bacteria containing
fertilizers (LBCF) were examined on how the treatments modify heavy metal
uptakes. Dry matter accumulations in shoots and roots, length of shoots and
roots of maize were measured. Chlorophyll contents were determined by using
spectrophotometer methods. The dry matter accumulation and length of shoots
decreased, the dry matter of roots increased in all of the treatments
compared to the nutrient solution without treatment (control). Increased
chlorophyll a, b and carotene contents were observed at 4 g dm-3
Ss and 4 g dm-3 Ss + bio fertilizer treatments.
