Vellanikkara, during 1995-1997.
The study was aimed to find out the effect of organic manu ring and
chemical fertilisers on the levels of lAA and its influence on growth and yield of
brinjal by monitoring the activity of indole acetic acid oxidase in plant leaves at
different stages of plant growth.
The experiment was laid out in randomised block design with 13
treatments and three replications. The treatments include combinations of different
levels of organic manure and fertiliser, that is, zero, normal recommended dose and
double recommended dose with an without foliar application of 150 ppm !AA and
absolute control.
IAA oxidase activity was found to increase with the age of the plant upto
the tlowering stage and thereafter it was found to decrease. Application of treatment
was found to influence the IAA oxidase activity only at the fruiting stage of the
plant. Height, number of branches; flowers and fruits per plant and average fruit
weight were not significantly influenced by the treatments. Howe~er fruit yield in
brinjal was increased by the application of FYM, fertiliser and laa. Fruit yield was
increased when IAA was applied along with FYM or fertiliser alone or in
combination.
Plant N content was found to decrease from vegetative to flowering phase
and thereafter it was found to increase. But the application of different treatments
could not enhance the plant N content significantly.
But the P contents was influenced significantly due to treatments K
content was not influenced due to treatments. Potassium content of the plant was
found to decrease with advancing growth stages. However, K content of the plant
was not found to vary significantly.
Treatments in general, enhanced the Fe and Mn content of the plant and
the relative content of Mn in tissues at all stages of growth remained considerably
lower than that of Fe. Fe and Mn contents of the plant bad no influence on !AA
oxidase activity in this experimental condition.
Application of FYM, fertiliser and their combination with and without
supplementary addition ofIAA permitted significant difference in the uptake ofN, P
and K compared to that in control.
Maximum uptake of N and P was recorded by the treatment which
received IAA application along with the double dose of fertiliser and FYM.
