2. What are Bio-inoculants ?
Microbes that
Fix N
Solubilize P, K, Zn...
Mobilize nutrients-Mycorhiza
Produce PGP substances
Act as bio-control organisms
Improves growth, yield of plants and soil health
3. NEED FOR BIO-INOCULANTS
• Microbes – less in number and efficiency in
soil
• Increasing demand for Bio-inoculants
• Focus on conserving environment & soil
health
• Govt. Policy to supply quality seeds and
increase production
4. Bioinoculants recommended for Oilseeds and Pulses
Type of Bioinoculant Recommended crop
Nitrogen fixers
Rhizobium
All pulses, Ground nut
Azospirillum, Azotobacter All oilseed crops
P solublizing bacteria
Bacillus, Pseudomonas
All pulses and oilseed crops
P mobilizers
AM fungi
All crops
K, Zn solublizers
Bacillus
All crops
Sulphur solublizers
Thiobacillus thiooxidans
Oilseed crops
PGPR & Biocontrol agents
Pseudomonas fluoresense,
Trichoderma viride
All crops
5. Method of Inoculation
Biofertilizers
Seed Treatment – 400 to 600g / ac
Soil application – 2kg / ac
Biocontrol agents
Seed Treatment – 4 to 10g / kg seed
Soil application – 2kg / ac
6. Conclusion
Bioinoculants provide
Essential nutrients to crops
Produce PGP substances
Improves growth and yield of crops
Protects crops against diseases and pests
Reduces the cost of cultivation
Improces soil fertility
And also ecofriendly
