Distribution of Gypsum - Oil Seeds

What is the Distribution of Gypsum scheme for oilseeds?

Distribution of Gypsum is an input subsidy component of the Department of Agriculture and Farmers Welfare, Government of Tamil Nadu. Under it, farmers receive a subsidy of 50 per cent of the cost of the material plus transport, limited to Rs 750 per hectare, towards applying gypsum to an oilseeds crop.

The component appears in identical terms under both the oilseeds and the pulses sub-schemes of the Integrated Scheme for Oilseeds, Pulses, Oilpalm and Maize (ISOPOM). It matters most to groundnut growers and to registered seed growers producing Foundation and Certified class seed for supply back to the Department of Agriculture.

Why gypsum, and not ordinary fertiliser. Gypsum is calcium sulphate. It supplies two nutrients that ordinary NPK fertiliser does not; calcium and sulphur, and it supplies them in a form that dissolves slowly in the soil without raising pH.

For groundnut the agronomy is specific and unusual. A groundnut plant flowers above ground, then pushes a peg down into the soil where the pod develops. The developing pod absorbs calcium directly through its own shell from the surrounding soil, not through the root system. Calcium applied to the roots does not reach the pod. That is why gypsum is broadcast into the pegging zone at flowering: roughly 40 to 45 days after sowing, and why its absence shows up as "pops": shells that form but never fill with a kernel. Poor calcium in the pegging zone is one of the commonest causes of low groundnut yield in Tamil Nadu's dry districts.

For sesame, sunflower, castor and soybean, gypsum's value is mainly the sulphur. Oilseeds need substantially more sulphur than cereals do because sulphur is a building block of the oil itself; a sulphur-deficient oilseed crop produces both a smaller yield and a lower oil percentage from the same seed.

Why transport is in the subsidy. Gypsum is applied at several hundred kilograms per hectare. It is heavy, cheap by weight, and often has to be carted from a distant depot. In many blocks the transport cost approaches the material cost. The department's decision to write the subsidy as material plus transport rather than material alone is what makes the component usable in remote blocks at all.

Who is eligible for the gypsum subsidy, and who is excluded?

A farmer can claim if:

• The applicant cultivates an oilseed crop; groundnut, gingelly, sunflower, soybean or castor, or a pulses crop, in a district covered by the relevant ISOPOM component.
• The applicant holds or cultivates land evidenced by chitta and adangal or patta, and is registered with the Agricultural Extension Centre.
• The applicant is a registered seed grower producing and supplying Foundation and Certified class seeds to the Department of Agriculture. Seed growers enrol under the Seed Multiplication Scheme of Paddy, Millets, Pulses, Oilseeds and Cotton, register the seed farm with the Assistant Director of Agriculture of the block on payment of the requisite fee, and receive a training at the beginning of each year.
• The applicant falls within the season's allocation for the block. The departmental scheme document describes ISOPOM input components as available to farmers "limited to target".
• The applicant is a small or marginal farmer, a woman farmer or an SC or ST farmer, in which case priority applies. The scheme mandates a 24 per cent flow to SC and ST farmers and a 20 per cent flow to women farmers and women's groups.

A farmer cannot claim if:

• The land is outside the districts covered by the ISOPOM oilseeds or pulses component this season. Under the National Mission on Oilseeds and Oilpalm, for example, farmers in Kanyakumari, Chennai and The Nilgiris are excluded from the oilseeds seed components.
• The applicant has no land record linking them to cultivated land in the block. A labourer without cultivation rights is not eligible.
• The crop is not an oilseed or pulse covered by the component.
• The block target is exhausted for the season.
• The applicant has already drawn the same per-hectare subsidy for the same land in the same season.

How to apply for the gypsum subsidy in Tamil Nadu

1. Visit the Agricultural Extension Centre in your village and meet the Assistant Agricultural Officer, who holds the block's current target and the district coverage list for the season.
2. Confirm your crop and district qualify under the ISOPOM oilseeds or pulses component operating this year, and register the hectarage you intend to treat.
3. Register your seed farm first if you are a seed grower. Enrolment under the Seed Multiplication Scheme is done with the Assistant Director of Agriculture of the block on payment of the requisite fee, and the source seed is supplied by the department through the Agricultural Extension Centres at the fixed sale price.
4. Submit the application with chitta and adangal or patta, Aadhaar and bank passbook. Several districts direct farmers to apply first through the Uzhavan mobile app and then to lodge the papers at the block agricultural office.
5. Attach a community certificate if claiming under the 24 per cent SC and ST allocation, or record your status as a woman farmer for the 20 per cent flow.
6. Wait for sanction from the Agricultural Officer or Deputy Agricultural Officer at the block, countersigned by the Assistant Director of Agriculture as required.
7. Collect the gypsum or make the purchase. Where the department distributes the material, collect it against the sanction. Where the subsidy is reimbursed, keep both the purchase bill and the transport receipt: transport is part of the eligible cost, and a claim without the transport receipt loses part of the entitlement.
8. Apply the gypsum at the right stage. For groundnut, broadcast into the pegging zone at flowering, around 40 to 45 days after sowing, and earth up. Applying at sowing wastes most of the calcium benefit.

What other input subsidies come with this one

A farmer registering for gypsum should ask about the rest of the package in the same visit; the paperwork and the season window are identical.

Under the oilseeds component of ISOPOM:

Under the pulses component, gypsum carries the same Rs 750 per hectare ceiling, alongside Rhizobium at 50 per cent or Rs 100 per hectare, Nuclear Poly Hedrosis Virus at 50 per cent or Rs 250 per hectare, DAP spraying at 50 per cent or Rs 100 per hectare, and micronutrient spray at 50 per cent or Rs 70 per hectare.

Under the National Mission on Oilseeds and Oilpalm, gypsum also enters through compact block demonstrations of a minimum of 50 hectares each, where a 50 per cent subsidy on the cost of inputs — seeds, bio-control agents, micronutrient mixture, bio-fertilisers and gypsum, plus sowing with a seed drill and weedicides; is limited to Rs 7,000 per demonstration for groundnut with a ceiling of one hectare per beneficiary.

What the seed grower route pays

Farmers who take the seed-production route rather than the ordinary cultivation route earn a premium on top of the input subsidies. Under the Seed Multiplication Scheme:

• Groundnut, premium of Rs 3 per kg for Foundation class seed, Rs 2 per kg for Certified class, and Re 1 per kg for Truthfully Labelled class.
• Gingelly, sunflower and soybean, premium of 7.5 per cent over the local market rate for Foundation class and 5 per cent for Certified class.
• Castor; 30 per cent over the local market rate for Foundation class and 20 per cent for Certified class.
• Pulses, Rs 2 per kg for Foundation class and Re 1 per kg for Certified class.

The department pays 90 per cent of the Minimum Support Price as an advance when the seed reaches the Seed Processing Unit, and the balance after the Seed Testing Laboratory declares the lot standard. If the lot fails to meet the standard, the farmer repays the entire advance in one instalment before taking back the stock.

Which offices handle the application

Why applications fail

• District not covered by the ISOPOM component this season.
• No land record linking the applicant to cultivated land in the block.
• Crop not eligible. The component sits inside the oilseeds and pulses programmes.
• Transport receipt missing, so the reimbursement is computed on material cost alone and falls short of the entitlement.
• Seed farm not registered where the claim is made as a seed grower.
• Block target exhausted for the season.
• Applied too late. Gypsum has to reach the field before flowering; a sanction issued after pegging is of no agronomic use even if the money is paid.

Help and grievance

• Village level: Assistant Agricultural Officer at the Agricultural Extension Centre.
• Block level: Agricultural Officer, Deputy Agricultural Officer and the Assistant Director of Agriculture.
• District level: Joint Director of Agriculture at the Collectorate.
• Online: the Department of Agriculture and Farmers Welfare portal at tnagrisnet.tn.gov.in, and the Uzhavan mobile app.

The subsidy is a government entitlement against a published rate. No dealer or trader is authorised to charge a commission for arranging it.

How to check your application status

The gypsum component is sanctioned locally at the block, and Tamil Nadu's agriculture department does not run a separate online tracking number for this input subsidy the way some cash-transfer schemes do. Status checking is mostly a matter of following up with the office that holds your file.

• Ask at the Agricultural Extension Centre first. The Assistant Agricultural Officer who took your application keeps the block's sanction register for the season. This is the fastest way to find out whether your hectarage has been cleared against the target, or is still pending.
• Escalate to the block office if the Extension Centre has no update. The Agricultural Officer or Deputy Agricultural Officer, and where relevant the Assistant Director of Agriculture, countersigns sanctions and can confirm whether your paperwork has moved beyond the village level.
• Check the Uzhavan app if you applied through it. In districts where the department routes applications through the Uzhavan mobile app, the app shows the applicant their own submitted request; it is not a substitute for visiting the office if the block itself has not acted on the request.
• Use tnagrisnet.tn.gov.in for general scheme and season information, such as whether the ISOPOM oilseeds or pulses component is currently open in your district. The portal is a reference source for scheme rules rather than a per-applicant tracking dashboard.
• If the gypsum is being physically distributed rather than reimbursed, status is effectively whether the stock has arrived at the Extension Centre. Ask specifically whether the block's gypsum consignment for the season has been received, since a sanction can be approved on paper before the material itself is in hand.
• Keep your application reference or the date you applied. The subsidy is processed against a season and a block target, not a searchable online ticket number, so the officer handling your file will look it up by your name, survey number, or the date you applied rather than by a reference code.

If a sanction has been granted but the gypsum has not been collected or the reimbursement has not been paid before the sowing window closes, raise it with the Joint Director of Agriculture at the district Collectorate, since delays that miss the flowering stage make the subsidy agronomically useless even if the money is eventually released.
