Phenylalanine ammonia lyase content in leaves of groundnut ranged from 30.40 to 42.14 and 25.07 to 34.71 units when sodium meta silicate was applied as foliar spray (@ 0.5, 1.0, 2.0, 3.5 and 5.0%), and soil application (@ 5.0, 7.5, 10.0, 15 and 20%) and 33.78 to 52.89 and 30.04 to 41.66 units when calcium silicate was applied through leaves and soil at the same doses, respectively in contrast to 22.62 units in plants without silica fertilizer applications. Among the two sources of silica fertilizers tested, foliar spray of calcium silicate at 5 per cent was effective in facilitating the increasing the activities of Phenylalanine ammonia lyase (PAL) in groundnut leaves.
