Abstract
The present study “Effect of microbial consortium (Biofertilizer) on growth and nutrient
uptake by poplar clones in nursery” was conducted in teaching area, Department of Forestry
and Natural resources, PAU, Ludhiana during the year 2015-2016. The influence of different
doses of microbial consortium (biofertilizer) addition to nine different poplar clones in
nursery on growth and nutrient uptake was studied. In present study different doses of biofertilizers
showed the significant variation for collar diameter, leaf area, biomass
accumulation, nitrogen, phosphorus and potassium concentration (%) except plant height and
also revealed significant differences for accumulation of N, P and K. Study also revealed that
the interaction between different doses of biofertilizers and clones shows the significant
results for collar diameter, leaf area, plant height, nitrogen, phosphorus and potassium
concentration(%) except in plant biomass. The application of microbial consortium
(biofertilizers) increases the growth parameters, and nutrient uptake in plants. Application of
microbial consortium resulted in enhanced growth for most of the characters and can be
applied as alternative to chemical fertilizer for enhanced growth and better nutrient uptake in
Populus deltoides plants.
