उत्तर १
Glomus fungi belong to the genus of fungi which are found in symbiotic relationship with the roots of the seed plants (mycorrhiza). It absorbs phosphorus from the soil and passes it to the plant and the in return derives sugars from the plant cell for survival. Thus the application of the fungal genus, Glomus, to the agricultural farm increases the farm output due to increased phosphorus availability to the crops.
उत्तर २
The fungal genus Glomus forms mycorrhiza, absorbing phosphorus from soil and passing it to plants, enhancing nutrient uptake, resistance to pathogens, tolerance to salinity and drought, and overall plant growth, thereby increasing farm output.
