abstract
A study on “Effect of Amino acid formulation sprayed mulberry leaves on silkworm growth and cocoon yield parameters at department of Sericulture, UAS, G.K.V.K., Bengaluru during 2016-17.Silkworms (PM x CSR2) fed with V-1 mulberry during late age registered significantly shorter fifth instar larval durations (169.00 hr), total larval duration (608.00 hr), cocoon number (48.50 /50 worms), cocoon weight (92.83 g/50 cocoons), maximum ERR (96.67 %), maximum single cocoon weight (1.92 g), single shell weight (0.31 g), single pupal weight (1.61 g), shell ratio (19.40 %) finer denier (2.39) and filament length (835.67 m) respectively were recorded when silkworms were fed on mulberry raised with 3.5 % amino⁺ spray on 25^th and 35^th day after pruning. The details are discussed.
