Intensive agriculture involving high crop intensity, unavailability of organics, and higher use of
straight fertilizers causes imbalanced use and deficiencies of several other macro and micronutrients.
Nutrients supply through the integration of microbial consortium containing Gluconacetobater
diazotrophicus, Trichoderma harzianum, and Pseudomonas fluorescens can reduce the requirements
on the one hand and can also increase the response of chemical fertilizers. Thus we had planned
the present experiment with the objectives (i) to determine the effect of integrated application of
microbial consortium (MC) and NPK fertilizer on soil quality parameters and crop growth and yield
attributes and (ii) to assess the effect of integration on agronomic efficiency of N, P and K and find
out the possibilities for reduction in applied doses of NPK, if any. Five treatments viz., T1;
N0P0K0;
T2:
N75P13K25;
T3:
N150P26K50;
T4:
N75P13K25
+ microbial consortium and T5:
N150P26K50
+ microbial
consortium containing new strains of Trichoderma harzianum, Gluconcetobacter diazotrophicus, and
Pseudomonas fluorescens (CFU 109–
10 per ml liquid culture) were evaluated under four replications in a
randomized block design (RBD). Experimental results indicated that integrating microbial consortium
and NPK fertilizers’ application proved effective in improving soil organic carbon, soil microbial
population, microbial biomass carbon, microbial biomass nitrogen, and soil respiration. Integrated
use of microbial consortium with NPK also improved the cation exchange capacity of soil and
roots. However, the growth and yield attributes, nutrients uptake, sugarcane, and sugar yields also
revealed a positive effect of microbial consortium’s integrated application with NPK. The integration
of MC and NPK also improved the agronomic efficiency of applied nutrients (NPK). Reduction of
50% NPK with these microbial consortia (Trichoderma harzianum, Gluconcetobacter diazotrophicus,
and Pseudomonas fluorescens) was found better than the application of full NPK through chemical
fertilizers. Thus application of N150P26K50
with microbial consortium can sustain soil fertility besides
improving sugarcane and sugar yields in subtropical Indian conditions.
