Description A pot culture study conducted to know the effect of individual and combined
microbial inoculants on growth and yield of ginger has revealed that, combined
application of Azospirillum brasilense + Aspergillus niger + Trichoderma harzianum +
Glomus fasciculatum was best in improving the plant growth. Based on the results of
pot culture studies, the above microbial consortia was further tested at three levels of N,P
and Zn with FYM / Vermicompost in a location trial (field experiment) conducted at
Aladahalli village of Hassan taluk. Combined inoculation of Azospirillum brasilense +
Aspergillus niger + Trichoderma harzianum + Glomus fasciculatum with 100 per cent
N, P, K and Zn + FYM was found best and was statistically on par with
A. brasilense + A. niger + T. harzianum + G. fasciculatum + 75% N, P, Zn + 100% K +
FYM in improving the plant height, number of tillers, number of leaves and leaf area at
45, 90, 135 and 180 days after planting with increase in rhizome yield, oleoresin content,
plant nutrient uptake and lowest rhizome rot. Among these two treatments the above
microbial consortia with 75% N, P, Zn + 100% K + FYM was found economically
advantageous in obtaining higher yield and in terms of saving 25% N, P and Zn
application.
The best treatment combination A. brasilense + A. niger + T. harzianum + G.
fasciculatum + 75% N, P, Zn + 100% K + FYM was further tested in eight different
villages of Hassan taluk (multi-location trials) in comparison with farmers practice and
UAS(B) recommended package of practice. Results showed that the above tretment
combination was found best in improving the growth and yield of ginger.
