What are the advantages of VAM in mulberry cultivation?

[a] Vesicular Arbuscular Mycorrhizal (VAM) inoculation for new mulberry plantation: Soil based inoculum of VA-mycorrhiza containing mixed culture of Glomus mosseae and G. fasciculatum is used for raising mycorrhizal mulberry saplings in nursery beds. About 5-6 months old mycorrhizal saplings are transplanted to the main field along with nursery soil containing VAM spores. Phosphorus can be used @ 60 kg / ha / yr instead of 120 kg / ha/ yr after one year of establishment. The VAM inoculation ensures 50% curtailment of chemical phosphorus application in mulberry cultivation without any loss in leaf yield and quality.

[b] Inoculation of established mulberry garden with VA-mycorrhiza: To inoculate an established mulberry garden (more than 2 years old) with VA-mycorrhiza, at first the garden is pruned and intercultural operations are completed. VAM inoculum is applied @ 1000 kg / ha making furrows to a depth of 7.5 - 10 cm in between mulberry rows. After the application of VAM inoculum, maize seeds (local variety) @ 20 kg/ha are sown in furrows at a distance of approximately 5-10 cm from each other for multiplication of VAM in the roots of maize plants and covered immediately. After 40-45 days growth of maize , the plants are cut at the height of 20-30 cm and allowed to grow for another 30-40 days. After 80-85 days, the maize plants are cut to the ground level and maize roots colonized by VAM are incorporated in the soil by ploughing. From the next crop onwards, phosphorus is to be applied @ 60 kg/ ha/ yr in place of 120 kg/ ha/ yr.
