Abstract

The quality and quantity of mulberry leaves var. Si associated with three strains of Va mycorrhiza separately with graded levels of phosphorus (180, 90, 60, and 30 Kg P/ha/yr) were studied at CSR&TI, Berhampore (W.B.) for 2 years (1996-97 & 1997-98). Two years average data revealed the overall improvement in leaf yield, leaf moisture (%) and P uptake by leaves in all thė VAM-treated mulberry plants (Var. S1) particularly associated with Glomus mosseae_at 30Kg P/ha/yr which statistically found to be at par with control (180 Kg P/ha/yr without VAM) and other treatments. The silkworm rearing result with Multi x Bi (CB5 x P5) hybrid indicated the overall improvement in larval weight, single shell weight, S.R.%, absolute silk content in mycorrhizal leaves of any of the strains under reduced doses of P when fed to silkworms, while ERR, filament length, denier and non-breakable filament length were found to be at par with control. It was further observed that Glomus etunicatum with 50% reduced dose of P during favourable season and G. fasciculatum with 67% reduced dose of P during unfavourrable season performed better result in respect of important economic characters of rearing and reeling.
