Abstract:

Food production is increased more than three times. This success is due to high yielding crop varieties, agrochemicals, irrigation system and chemical fertilizers. High input use has led to increased land degradation, pest resistance, loss of soil fertility, nutrient imbalance and depletion of soil organic matter etc. In the light of these problems, the use of organic fertilizers, biofertilizers i.e. microbial products are crucial to make the agriculture industry a viable component of a healthy and pleasant ecosystem. Thus, incorporation of the natural roles of beneficial microorganisms in maintaining soil fertility and plant productivity is gaining importance and may be an important approach. To identify mycorrhizal occurrence and association among different plants in Rajshahi university campus, mycorrizal association was observed and percentage of root colonization were varied from 10-90%. Symbiotic association of about 85% plants with arbuscular mycorrhizal (AM) fungi plays an essential role in plant growth, plant protection. AMF improve phosphate intake for the plants when phosphate availability is limited; and hence, beneficial to plant growth. The frequency of mycorrhizal infection was significantly correlated with soil pH, moisture, water holding capacity, texture, total nitrogen, organic, calcium, magnesium, potassium etc. This investigation showed that especially phosphorus and nitrogen in the soil greatly influenced the plant root infection by AM. Vesicular arbuscular mycorrhizal spores were extracted from rizhosphere soils using sucrose density gradient centrifugation, wet sieving method. Codiaeum variegatum could be considered as the initial natural source of AM and used as the stock plant to provide inoculum of AM for biofertilizer. Inoculation with AMF improves plant growth and productivity, nutrient profile, and thereby crop improvement. AMF could be used as a biofertilizers in the future towards sustainable agriculture in reducing problems associated with the use of chemicals.
