Among the different treatments, T5 (350:140:140 NPK kg/ha/year + FYM 20 t/ha/year + micronutrient formulation of Zn, Fe and Mn @ 6 kg/acre) recorded significantly higher plant height (169.50 and 211.61 cm), shoot height (65.15 and 170.56 cm), number of shoots/plant (30.11 and 30.17), shorter internodal distance (5.13 and 5.14 cm), number of leaves/plant (548.67 and 567.56), leaf area (283.52 and 310.45 cm2), leaf yield (947.20 and 1040.81 g/plant) and leaf dry matter (359.05 and 552.05 g/plant) on 45th and 75th DAP in V1 mulberry. The quality parameters viz., leaf moisture (76.16 %), chlorophyll a and b (1.63 and 0.92 mg/g), crude protein (24.40 %), crude fibre (14.07 %), total carbohydrates (34.66 %), total sugars (16.10 %), leaf N (3.84 %), P (0.45 %), K (1.70 %), Ca (1.71 %), Mg (0.64 %), S (0.55 %), Zn (62.01ppm), Fe (497.17 ppm) and Mn (149.76 ppm) were also found significantly maximum in T5 on 75th DAP. Significantly higher larval weight (37.59 g/10), shorter fifth instar and total larval duration (198.32 and 510.32 h), ERR (98.83%), cocoon weight (87.57 g/50 cocoons), cocoon number/50 worms (49.42), single cocoon weight (1.78 g), single pupal weight (1.39 g), single shell weight (0.39 g), shell ratio (21.69 %), filament length (999.95 m) and NBFL (950.42 m), were significantly higher in T5 treatment with PM × CSR2. Compared to other treatments all the above-mentioned parameters found least in the control.enThesis
