Abstract
Batley seedlings were grown in
nutrients solution to study the effect of aluminium (0.0. 0.2, and 0.6 mM) on plant growth and mineral nutrition . chlorosis appeared on the young leaves of Altoxic plants and
was severe on high Al level . stems of the Al0treated plants were purple. While the roots were short thick and brown in colour . dry matter yield of barley shoot and root decreased progressively with increase in Al-level
. the concentration of K. Ca Mg and Mn substantially decreased in shoot and root while P decreased in shoot but it increased in root with high Al compared to control. With increased Al levels the concentrations of Al and Zn increased in shoot and root, while i.e content in shoot was not greatlu affected but in root decrease in Fe
