Action Plan - Central Silk Board

• ‘Poshan’ – a multi-nutrient formulation for mulberry
Technologies Commercialized
• ‘Poshan’ – a multi-nutrient formulation for mulberry
• ‘High sprayer pump’ – for rearing house disinfections,
• ‘Biofertilizer’ - for mulberry plants
• ‘Navinya’ - a bio-formulation for root rot disease
Decisions:
Soil testing can be continued as a service and soil health monitoring activity
Efforts should be made to popularize Vishala and Anatha mulberry varieties by
collecting the cutting material from the respective progenitors. If any problem in
procuring the material, it should be brought to the notice of Central Office.
Make Action Plan for large scale field testing of L14 X CSR2 in consultation with
NSSO, CSTRI Bangalore and DoS.

• Seven new progenies were identified at Primary Yield Trial (PYT) level with more
than 20% gain in leaf yield over the S-1635. From another trial, 7 hybrids with
19.5% to 58.5% gain over the check (S-1635) were identified.
• The spacing [(90+120) x 60 cm] of mulberry plantation (S-1635) was found better in
terms of quality leaf production (29.5 mt/ha/year) and maintenance of soil fertility.
• Leaf samples from 126 farm’s/ farmers’ fields at 16 locations were analysed for
micronutrients and observed zinc deficiency in most cases.
• The mulberry variety C-2028, selected for tolerance to waterlogging yielded 6.96
mt/ha/crop under flooded condition.
• Foliar application of 1% KCl on mulberry increased leaf yield to 5.9 to 6.9% over the
control (no spray) at farmers’ fields in Deogarh, Bhandara, Koraput, Ranchi and
West Bengal under rainfed conditions.
• Pruning of the plants during June with application of Morizyme-B resulted in
increase of leaf yield by 17.3% and reduced Pest and Disease incidences.
• Supplementing Vermicompost with recommended FYM and NPK produced 6.4%
more leaf yield to fetch a net profit of Rs. 22696/- per ha per year.
• Chemical insecticide, Thiamethoxam (0.015%) was identified more effective with
the safe period of 14 days for silkworm rearing to combat menace of whitefly.
• A disease forecasting model for Bacterial leaf spot disease for Murshidabad district
was developed.
• Application of Pongamia oil (1%) was found effective in reducing the pest
population within 15 days after spray. However, on the safety point of the silkworm,
1% Neem oil was more desirable for management of leaf webber.
