COCOON PARAMETERS OF PM X CSR2 FED WITH MULBERRY RAISED THROUGH ORGANIC BASED NUTRIENT MANAGEMENT

The cocoons spun by PM x CSR2 fed on mulberry grown by supplying with different types of organic manures exhibited notable influence on cocoon traits. Pooled data of three rearings revealed that, the maximum single cocoon weight (1.90 g), pupal weight (1.53 g) and shell weight (0.365 g) were recorded when youngage silkworm fed with S36 mulberry grown by 100 % Rec. N through 20% each of Compost + Glyricidia maculate + Castorcake + Vermicompost and Urea + 10 kg each of Azospirillum brasilense + Aspergillus awamori Biofertilizer + remaining P, K through chemical fertilizers (T8). However, same worms fed with two different mulberry varieties during late age, V1 mulberry registered significantly maximum cocoon weight, pupal weight and shell weight (1.82 g, 1.47 g and 0.345 g respectively) compare to M5 mulberry. Similarly, among interactions of treatment with mulberry varieties, T8 x V1 combination registered significantly maximum single cocoon weight (1.92 g), pupal weight (1.54 g) and shell weight (0.371g) over other combinations.
