Response of Eggplant (Solanum melongena L.) to fly ash and brick kiln dust amended soil
In the present study, the effect of different fly ash and brick kiln dust levels in soil (0%, 5%, 10%, 20%, 30%, 40% and 50%) were observed on growth performances and yield of eggplant. For the experiment, one kg of each mixture was filled in pots and the pots containing only soil served as Control. The plant growth (length of shoot and root; fresh wt. and dry wt. of shoot and root; leaf / plant; leaf area / plant; branch / plant) and yield (flower / plant; flower size; fruit / plant; fruit size) parameters were taken. Plant growth and yield were significantly increased from 5 to 30% level in fly ash amended soil and from 5 to 40% level in brick kiln dust amended soil. However, at higher levels i.e. 40 & 50% levels in fly ash and 50% level in Brick kiln dust, growth and yield parameters reduced significantly. The perusal of the data revealed that 20% level of fly ash and 30% level of brick kiln dust amendments in soil were found to be ideal level for the better plant growth and yield of eggplant.
