A field experiment was conducted during 2014-16 at Regional Sericultural Research Station farm and two farmers’ field in Kalimpong hills, West Bengal, India with five treatments and four replications to study the integrated effect of treated pressmud and FYM on growth attribute characters, yield and quality of existing BC259 (Morus alba L.) mulberry variety. This experiment was also extended to check its adverse effect on bioassay of SK6´SK7 (Bombyx mori L.) silkworm. Based on data analyzed, it was found that, the integrated application of 02 mt treated press mud with 05 mt FYM (T3) performed better than application of 10 mt FYM alone (T1). The highest annual leaf yield among above experimental sites was ranged from 11.09 to 14.71 mt ha-1 after the application of T3 treatment. The total leaf yield gain in T3 treatment was 15.28 to 19.26% higher than control. The nutritional quality like moisture content 76.84%, total chlorophyll 1.67 mg g-1, total soluble protein 25.78 mg g-1, total soluble sugar 34.85 mg g-1, total N 3.44%, total P 0.35% and crude protein 21.53% were also recorded as higher with T3 than control. Bioassay of silkworm reveals that, the mulberry leaves with T3 treatment have significant result on single cocoon weight, cocoon yield/ 100 dfls and shell% respectively. The higher cost benefit ratio was also recorded as 1:1.89% with net profit Rs.1.70 Lakhs/ ha/year after the application of T3 treatment than control.
