Turmeric
Turmeric
is mainly known as a spice all over the world. India is by far the largest
producer and exporter of turmeric in the world. Indian turmeric is considered
the best in the world market because of its high curcumin content (6.7%). Odisha
contributes about 21 % of India’s turmeric cultivation in terms of productivity. Chemical
fertilizers are extensively used in turmeric crops which caused various threats
to environmental, human, and soil health over a period of time. However, soil
microorganisms play a significant role in regulating the dynamics of organic
matter decomposition and the availability of plant nutrients. Hence, the
application of biofertilizers is becoming popular these days as an important
alternative to chemical fertilizers. On the basis of the application of
bio-fertilizers, it can be broadly classified as:
- Nitrogenous
(N) bio-fertilizer
