 ABSTRACT

The present investigation was carried out during spring (2019). The collected data revealed that, Vishala recorded maximum moisture content (76.83 %) followed by C-2038 (76.61 %) whereas minimum was noticed in S-1635 (74.64 %) during chawki stage of silkworm rearing. During late age of silkworm rearing, C-2038 recorded maximum moisture content (77.24 %) followed by S-1635 (76.02 %) whereas minimum moisture content was noticed in G-4 (72.98 %). The overall mean revealed that, C-2038 recorded maximum moisture content (76.93 %) followed by Vishala (75.80 %), whereas minimum moisture content was noticed in G-4 (74.19 %) and significant differences were observed among all the varieties with respect to moisture content for chawki, late age and overall mean during complete rearing. G-4 retained maximum moisture content (95.79 %) followed by C-2038 (95.73 %) during chawki stage. During late age, Vishala retained maximum moisture content (96.16 %) followed by S-1635 (96.03 %). For overall mean, C2038 & G-4 retained maximum moisture content (95.73 %). All the varieties showed statistically non - significant among each other for moisture retention capacity at 6 h for chawki stage, late age and overall mean. All the varieties showed significant differences among each other for moisture retention capacity during chawki stage at 12 h, C-2038 retained maximum moisture retention (92.71 %) followed by G-4 (92.33 %). During late age, C-2038 retained maximum moisture (92.09 %) followed by S-146 (92.08 %) and showed non - significant among them. For overall mean, there is statistical differences among all the varieties for moisture retention capacity at 12 h, C-2038 retained maximum moisture content (92.40 %) followed by G-4 (92.13 %). During chawki stage, higher moisture was retained C-2038 (89.17 %) followed by G-4 (88.02 %) and recorded significant differences among all the varieties at 24 h. During late age rearing, higher moisture was retained in variety C-2038 (86.34 %) followed by Vishala (84.72 %) and showed non-significant among all the varieties. For overall mean, higher moisture was retained in variety C-2038 (87.76 %) followed by G-4 (85.95 %). Among all the varieties there is significant differences was observed statistically at 24 h for overall mean. During chawki rearing according to the evaluation index for moisture content and moisture retention capacity, the mulberry varieties were shortlisted as C-2038 having E.I value 59.30 followed by G-4 (54.82) respectively. During late age rearing, C-2038 having E.I value 58.75 followed by Vishala (53.32) and for overall mean, the mulberry varieties were shortlisted as C-2038 having E.I value 61.79 followed by G-4 (51.76) and S-1635 (51.33) respectively.
