Production of native Arbuscular Mycorrhizal Fungi (AMF) in pot culture.
This technology involves
- isolation of native spores of AMF from rhizosphere
- Inoculation the spores in potting mixture containing Soil:FYM::3:1
- Host plants (with rich fibrous roots system), like, maize, sorghum, methi and marigold are used .
- After 3 months, infected root system along with the potting mixture is harvested.
- Part of it is used as inoculum for further pot culture and the rest is packed for supplying to the farmers.
- IP bio assay test and the number of spores is checked in every 3 months to ensure 25-30 spores per 100 g soil is present.
- Pot culture ensures production of AMF under controlled condition thus results in quality culture.
- This technology may easily be adapted by the rural women.
- Application of AMF in sunflower in combination with Azotobacter and organic manure has resulted in 20% increase in seed yield.
- Application of AMF in the potting mixture during the hardening stage has resulted in 15% reduction in use of chemical phosphate after its plantation in field.
