Next step. Review weather, crop, water-availability and operating evidence. Prepare water-needs scenario in the prototype creates a visible, downloadable draft. It is unassigned and not sent.

Calculated need is not an authorised irrigation release.

ETc = ETo × Kc. Net = max(0, ETc + percolation + desired storage increase − rainfall after runoff − capillary contribution). Gross = net × hectares ×10 / application efficiency.

The full local balance, rooting depth, stress, crop stage and operating constraints still matter. The paddy allowance is explicit and must be zero where inapplicable. This is not an authorized reservoir release.

What the selected record shows. The supplied 4,500 kg at 110 LKR/kg gives 495,000 LKR revenue. After 360,000 LKR variable costs, gross margin is 135,000 LKR.

Gross margin excludes fixed costs and is not net profit.

Gross margin = saleable output × realized price − variable costs. Divide by matching hectares for margin/ha; variable-cost break-even price = variable costs / output.

Keep fixed costs, family-labour opportunity cost, taxes and financing identifiable. Gross margin is not net profit. Crop, prices and costs are fictional coherent enterprise assumptions. Gross margin excludes fixed and financing costs; it is not household income or net profit.

Source. Sri Lanka publication.

Data needed. Rainfed status, agroecological zone, crop window, variety recommendation and current seed availability.

Method. Use the RRDI drought-tolerant recommendations for rainfed rice in the Dry and Intermediate Zones. Compare maturity duration with the planting window.

Worked example. A rainfed field in the Dry Zone has a short planting window. Compare the maturity periods of RRDI-listed Bg 251 and Bg 314 with that window before checking seed availability.

Next step. Refer fields in scope to the officer with a shortlist and document seed availability before advising farmers.

5. Documents and images

Your institution has its own document and image library. Use the same library for reports, photos and other evidence.

Open this screen for Department of AgricultureSee the presentation example

Department of Agriculture Documents and images prototype screen
Department of Agriculture. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open Documents and images. Check the institution name.
  2. Use All files, Documents or Images to find a file. Open its preview or download the original.
  3. Use a sample file to try Add file. Private is the starting choice. Public needs a source, permission to share and review.
  4. Use Access preview to try the institution reviewer and Public visitor views.

Files added in the prototype stay in this browser. Public sharing is an access preview. Existing public reference links already work online.

What your institution needs to confirm

6. Data structure management

Data structure keeps the existing source tree, records, charts and map. Manage structure adds a place to propose changes to definitions.

Open this screen for Department of AgricultureSee the presentation example

Department of Agriculture Data structure management prototype screen
Department of Agriculture. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open Data structure and choose Manage structure.
  2. Use Add base domain for a main information area. Add inside creates a subject area, a nested subject, an entity type or a field under the right parent.
  3. Give the definition a clear name, code and meaning. Reuse an existing definition when the meaning is the same.
  4. For a field, check the data type, unit, required value, limits and missing-value rule. Save a Draft, then try the separate reviewer view.

An entity type means a kind of thing or event, such as a reservoir or an inspection. Drafts stay in this browser. A demo approval does not change real definitions, data, chart links or sharing rights.

What your institution needs to confirm

7. Users and access

User management shows example profiles for each institution. People and Roles and access let you review the proposed account screens.

Open this screen for Department of AgricultureSee the presentation example

Department of Agriculture Users and access prototype screen
Department of Agriculture. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open User management and choose the institution. The rows are examples, not a list of your staff.
  2. Use View access to check a role. An administrator title alone does not give access to Private files.
  3. Try Preview invitation or Preview access change. Check the role, start date, optional end date and reason.
  4. Review the example permissions and tell us which job roles should receive each one.

These are interface previews only. They create no account, send no email and change no access. Use example details in the preview. Institution verification does not grant a real permission.

What your institution needs to confirm

8. Can you share data regularly?

We currently use public data and published reports where available. Please confirm whether your institution can provide data directly, so we can avoid retyping or reading figures from PDFs.

Do not enter passwords, access keys or private account details.

9. Anything else we should change?

Use the Download answers button at the top of this page. Share the downloaded file or printed copy through your agreed review channel. Nothing is sent automatically.
