| Abstract: | Application of
organic source of nutrient with no or very less quantity of fossil fuel based
inorganic fertilizers is becoming a popular practice for sustaining crop
productivity and soil fertility. However, there is a need to elucidate the
optimum combination of inorganic fertilizers, organic manure and biofertilizers
for specific crop and soil condition for the most economic output. In this
context, pot experiments were conducted with nine different treatment
combinations of organic manure (vermicompost), biofertilizer (CIM growR,
a plant growth promoting rhizobacteria (PGPR) and inorganic fertilizers (NPK)
to elucidate their influence on herb, oil yield, nutrient uptake and quality of
oil in rose scented geranium (Pelargonium
graveolens L’Herit.). Results revealed that combined application of
vermicompost, CIM Grow® and inorganic fertilizer produced higher herbage and
oil yield of geranium as compared to control and sole application of either
organic or inorganic fertilizer. Similarly, some of the principal constituents
like linalool, isomenthone, citronellol, geraniol and citronellyl formate were
also found maximum with conjugated supply of organic (vermicompost),
biofertilizers
and inorganic fertilizer. Maximum nitrogen and phosphorus uptake were recorded
under combined application of 50%
NPK + vermicompost @ 5 t/ha. Whereas, highest potassium uptake was recorded
with sole application of 100% NPK (T2). The extent of increase in
available N, P and K were about 4.0, 4.4 and 3.9-folds in post harvest soil
under integrated supply of nutrient, over their respective control.
Availability of copper, zinc and manganese were also enhanced by integrated
supply of organic, inorganic and biofertilizer. Iron content, however, was
either at par or reduced with combined application of vermicompost and
inorganic fertilizer as compared to sole application of CIM grow or
vermicompost. |
