Impact of thermal fly ash and cow dung on growth, yield and metal residues in Solanum melongena

Thermal fly ash with cow dung amendments caused significant improvement in soil quality. Water holding capacity (50.60-68.59), PH (6.05- 7.50) and few growth parameters (fresh weigh, roots length, shoot length) of S.melongena with the increase in Thermal fly ash and cow dung amendments. Fruit (edible part) of plants grown in fly ash and cow dung amended soil had metal residues (mg Kg-1) like Zn (24.56-35.42), Ni (1.23-1.66), Cr (0.81-1.42), Co (0.52-1.57), Pd (0.25-0.41) and Mo (0.98-1.44) within acceptable limits. Results indicate that soil amended with fly ash and cow dung at 150 tons ha-1, not only improved the physical properties of the soil but also contributed to the better growth and yield of brinjal (S. melongena).
