Which plants are used as bio biofertilizer?
Biofertilizers today Biofertilizers such as Rhizobium, Azotobacter, Azospirilium and blue green algae (BGA) have been in use a long time. Rhizobium inoculant is used for leguminous crops. Azotobacter can be used with crops like wheat, maize, mustard, cotton, potato and other vegetable crops.
What is the difference between biofertilizer and biopesticides?
Biofertilizers are live microbes whose primary effect is to enhance crop growth. Biopesticides are live organisms whose primary effect is to directly control crop pests and diseases.
How many types of biofertilizers are there?
It has been estimated that 40-250 kg N / ha / year is fixed by different legume crops by the microbial activities of Rhizobium….Biofertilizers – Types & their application.
| S. No. | Groups | Examples |

| Nitrogen (N2) fixing Biofertilizers | ||
| 1 | Free-living | Azotobacter, Clostridium, Anabaena, Nostoc, |
| 2 | Symbiotic | Rhizobium, Frankia, Anabaena azollae |
What do you understand by biofertilizers?
Biofertilizer can be defined as biological products containing living microorganisms that, when applied to seed, plant surfaces, or soil, promote growth by several mechanisms such as increasing the supply of nutrients, increasing root biomass or root area and increasing nutrient uptake capacity of the plant (Vessey.
What is mycorrhizae Class 12?
By definition, mycorrhiza is the product of a symbiotic association between fungi and green plants. The plants prepare sugar through the process of photosynthesis for the fungus, and in turn, the fungus provides essential minerals such as phosphorous to the plant.
How is biofertilizer made?
Solid-state fermentation and submerged fermentation are two main types of fermentation, used for the production of biofertilizers. Each type of biofertilizer is prepared by selection of efficient microbial strain, its cultivation using specific nutrient medium, scale-up, and formulation using solid or liquid base.
What is biopesticide PPT?
BIOPESTICIDES • Includes naturally occurring substances that control pest (biochemical pesticides), microorganisms that control pests (microbial pesticides) and pesticidal substances produced by plants containing added genetic material (plant incorporated protectants or PIPs)
What are the types of biopesticides?
Biopesticides are classified into three main categories: biochemical, microbials and plant-incorporated protectants.
What are biofertilizers Ncert?
Biofertilizers are organisms that enrich the nutrient quality of the soil. The main sources of biofertilizers are bacteria, fungi and cyanobacteria.
