Implementation of Catalytic Development Programme during XII Plan

(Operation modalities of sub components along-with physical and financial targets)


The diversity of Indian silk is enviable as India is the only country blessed with all the four types of silk viz., Mulberry, Tasar, Eri and Muga and among these, Muga silk is unique to India. The country accounts for a little over 17% of the total World silk production, producing 23,060 MT of raw silk (end of XI Plan) and stands second in the world silk production. Indian silks are broadly categorized into Mulberry and non-Mulberry (Vanya) silks. Mulberry silk is the most popular and technically equipped as a viable enterprise and contributes to 79% of total raw silk production. Production of Mulberry raw silk is mainly confined to the States of Karnataka, Tamil Nadu, Andhra Pradesh, West Bengal and Jammu & Kashmir which together accounts for 97% of the total Mulberry silk production. Three categories of Mulberry silkworms are reared in the country viz. Bivoltine which produces high quality silk of import substitute 3A grade, Improved Cross Breed capable of producing 2A to 3A grade silk for consumption in powerlooms, and Cross Breed / Multivoltine, which are much easier to rear, hardy and adopted to fluctuations in the environmental conditions.

Realizing the production potential of sericulture in the country and a need to meet the gap in demand and supply, a target to bring additional 59,331 ha (1,48,328 acres) of Mulberry plantation is suggested for XII Plan. Out of this, 15,600 ha (39,000 acres) would be taken up through the CDP programmes and the remaining through the MGNREGS, RKVY and other similar programmes of Central and State departments. From the already available plantation and by providing supporting infrastructure for the new plantation, the production of mulberry silk is targeted to reach 23,000 MT by the end of XII Plan. This includes production of 5,000 MT Bivoltine silk of 3A grade and 6,060 MT Improved Cross Breed of 2A to 3A grade which can be used for weaving in power looms, replacing the imported silk. This ambitious targets call for additional interventions through CDP. With the support from CDP, and tapping of funds from other resources, the national average productivity of silk is expected to increase from the current level of 90.55 kg / ha to 95.67 kg / ha. at the end of XII Plan. However, the productivity of Bivoltine silk is expected to be higher than 100 kg / ha. The Table below gives the status of area under food plants and production of raw silk at end of XI Plan, and projections for XII Plan under Mulberry sector.

(Raw Silk in MT)
  #   Performance Indicators Achievement (End of XI Plan)


Targets for XII Plan Anticipated increase

Over XI Plan

I Mulberry Plantation (Lakh Ha.) 1.81 2.40 33 %
II Mulberry Raw Silk Production
Bivoltine (3A and above grade) 1,685 5,000 197 %
Improved Cross Breed (ICB – 2A to 3A grade) 2,980 6,060 103 %
Cross Breed (below 2A grade silk) 13,607 11,940 Upgradation to ICB
Total Mulberry Raw Silk 18,272 23,000 26 %

The components proposed under Mulberry Seed and Cocoon sector are focused on production of Bivoltine and Improved Cross Breed (ICB) silk only during XII Plan, and hence no assistance of any type under these sectors will be extended for production of Cross Breed silk. As could be seen from the above Table that, the Cross Breed silk production of 13,607 MT by end of XI Plan will get scaled down to 11,940 MT by end of XII Plan as substantial volume of Cross Breed silk will be upgraded to ICB as per XII Plans strategy. For maintaining the level of multivoltine / Cross Breed production, or reduction due to upgradation to ICB, the support already provided under CDP till XI Plan will be optimally utilized. Besides, efforts will be made for maximization of benefits from existing capacity for improving the quality of CB silk. Resources will also be tapped from other schemes of the State and Central Government.

Seed Sector (For Bivoltine & ICB)

The growth trajectory of silk production could be sustained only through quality silkworm seed. Silkworm seed in the country is produced by various stakeholders i.e., Central Silk Board(CSB), State Sericulture Departments, NGOs and Private entrepreneurs. Central Silk Board plays a leadership role for nucleus, basic and commercial silkworm seed with intrinsic quality parameters in all spheres of silkworm seed production. The silkworm seed production system in India recognizes three generations, namely, nucleus, basic and commercial seed and provides adequate safeguards for quality assurance in the seed multiplication chain to maintain the vigour and purity of breeds as it flows from the breeders to the farmers. Silkworm seed industry is highly competitive thereby ensuring an efficient and responsible sector that offers farmers a continuous supply of high-yielding hybrids suitable for different environmental conditions for producing cocoon crops and products that will continue to meet the changing consumer demands.

Present scenario

National Silkworm Seed Organization (NSSO) is involved in the production of lion’s share of bivoltine hybrid seed and accounts for 70% of total bivoltine silkworm seed produced. The State Departments of sericulture in the states of Karnataka, Andhra Pradesh and Tamil Nadu also produce the bivoltine silkworm hybrid seed. About 75% of the commercial seed production is in the hands of Private Seed Producers producing mostly of cross breed silkworm seed. In the wake of implementation of Central Silk Board (Amendment) Act 2006, the maintenance of quality of silkworm seed is prime importance for the CSB. NSSO is involved in the maintenance, multiplication of basic seed of parental breeds of silkworm hybrids (both bivoltine and multivoltine) as per the quality norms of seed act regulations and supplies to various seed producing agencies.

The silkworm seed sector is geared up to increase the silkworm seed production to 32.78 crore dfls. by 2016-17 from the current (2012-13) production of 27.58 crore dfls. About 73% of the total silkworm seed requirement in the country is met by the registered seed producers (RSPs) in the private sector, while the State departments of sericulture and National Silkworm Seed Organization contribute 18 % and 9 %, respectively.

In consonance with the silk production target set for the XII Plan, the commercial seed requirement during the XII Plan is given below:

(Unit : Lakh Nos.)

Year Bivoltine ICB CB Total
2012-13 263 477 2,018 2,758
2013-14 310 557 2,013 2,880
2014-15 423 607 1,971 3,001
2015-16 519 717 1,885 3,121
2016-17 625 808 1,845 3,278

Substantial part of the silkworm seed (State: 25%; CSB: 11% and LSPs: 64%) would have to be produced in State and private grainages (LSPs). For undertaking this enormous task, the State and private sectors would be strengthened on certain critical areas, besides facilitating enhanced private participation in seed production. Moreover, the State and private seed production centres have to be prepared for implementing the recently enacted Seed Act. Measures have to be taken to revive the existing non-functional seed production units in the State and private sector by CSB for augmenting the seed production. These issues will be addressed during XII Plan through following interventions under CDP:

  • Franchise disinfection programme of NSSO.
  • Support to construct rearing houses for Adopted Seed Rearers(ASRs) of NSSO
  • Revolving Capital fund support for State grainages and RSPs
  • Assistance for purchasing seed testing equipments for State grainages and private RSPs
  • Support to strengthen basic seed farms of States.
  • Support to upgrade State and private commercial seed production units

All these components are basically meant to support production of Bivoltine and ICB silkworm seeds only. However, seed support for the Mulberry sector will continue for all varieties in order to achieve overall production target as male parent of bivoltine silkworm is required for cross breed silk production.

The component-wise objectives / description under the mulberry seed sector is as follows :-

1.Franchise disinfection programme of NSSO.

a) Brief description

This is an on-going programme of NSSO implemented under the Central sector during the XI plan, and proposed to be taken up under CDP during XII Plan period through private sector involvement. Under this programme, the Franchisee CRCs of NSSO (100units) will supply chawki worms to farmers ensuring high productivity. The commercial farmers covered under this programme are required to disinfect their rearing house before supply of chawki worms for ensuring crop stability and success. Seri polyclinics will be attached to the Franchisee CRC units to undertake the disinfection work. Each polyclinic will be provided with a power sprayer and a two / three wheelers for conducting the disinfection of rearing houses in their command areas. During the XII plan, 100 such units will be developed @ Rs.1.10 lakh per unit. The estimated cost of Rs.1.10 cr. will be fully met by CSB. The component will be directly implemented by NSSO.

b) Technical specifications / operational guidelines
  • The franchisee should use disiFranchise disinfection programme of NSSOnfectants authorized by CSB and NRDC and the quantity of the disinfectants and the method of disinfection should be as per recommendation of Research Institutes of CSB of particular zone.
  • The cost of disinfectants should be borne by the farmers.
  • The service charge for disinfection collected by the franchisee should not exceed 10%.
  • Support is extended only to bivoltine and ICB farmers.
    The details of activities under the component along with cost break-up are indicated in the Unit Cost (refer Unit Cost Book) of the component.
c) Physical Targets and Financial Projections:

The details of sharing pattern, Unit Cost, Physical targets and financial projections are given below:

NW 110,000
C & W 110,000
Eastern 110,000
NE 110,000

2. Support to construct rearing houses for Adopted Seed Rearers (ASRs) of NSSO

a) Brief description

The seed cocoons (required for layings production in NSSO) are produced through the selected Adopted Seed Rearers (ASRs). Some of the seed rearers do not have good rearing houses to take up the seed cocoon rearing. Since small quantities of DFLs are used for seed rearing, the rearing house will be small with reduced unit cost. Hence, under this component 275 seed rearers will be supported for constructing specially designed small rearing houses @ Rs.1.20 to 3.00 lakh per unit. The sharing pattern will be 50:50 by CSB and beneficiaries. An amount of Rs.4.62 crores is estimated for the component with a CSB share of Rs.2.31 cr. This will be implemented by NSSO.

b) Technical specifications / operational guidelines
  • The beneficiary should use specially designed rearing house model suggested by NSSO (Central Silk Board) by meeting 50% cost of rearing house and rear the recommended quantity of layings per batch.
  • The beneficiary should be a recognized ASR of NSSO, and attached to any of SSPCs of NSSO.
  • (S)He should be a seed cocoon producer registered under the Central Silk Board Amendment (Act) 2006 with a valid registration certificate issued by the Chair person, Registration committee.
  • The type of activities needed under the programme along with its cost break-up are indicated in the Unit cost (refer Unit Cost Book) of the component.
c) Physical targets and Financial Projections:

The details of sharing pattern, Unit Cost, Physical targets and financial projections are given in the table below:

Sharing pattern Category CSB State Beneficiary
General category 50% 50%
Special category 50% 50%

NW 1,25,000
C & W 1,25,000
Eastern 1,20,000
NE 1,20,000

3. Revolving Capital fund support for State Grainages and RSPs

a) Brief description

Working capital plays an important role in deciding the economic performance of the grainage. The silkworm seed production centres in DOS and private sectors often face difficulty in procuring quality seed cocoons due to shortage of Working Capital Fund. All the NSSO grainages are provided with Working Capital fund. Hence, it is proposed to replicate the same in State and Private grainages by providing one time Working Capital support to 485 grainages. Assistance @ Rs.1.35 to 5.00 lakhs per grainage based on production capacity in different zones shall be extended with a sharing pattern of 50:50 to be shared by CSB & State. The total cost estimated is Rs.13.06 cr. with a CSB share of Rs.6.56 cr.

b) Technical specifications / operational guidelines
  • The cost of seed cocoons required to produce commercial seed shall be covered under the component.
