Target audience

Small-landholder and progressive farmers

Primary age range: 20–60 years.

Target regions

Karnataka and Madhya Pradesh

Davangere and Chhindwara formed the initial focus.

Delivery team

Cross-functional field team

I worked as the product designer alongside 1 tech lead, 2 PMs, 5 engineers, 5 product owners, and 48 ground-team members.

Business goal

Improve smallholder farmers’ economic well-being and participation in the digital economy.

Build a supportive ecosystem that improves productivity and profitability.

Core user needs

  • Current nearby market prices and fair value realisation
  • Fast crop-disease identification and preventive guidance
  • Accurate weather and crop-health monitoring
  • Competitive agricultural inputs and farmer connections
  • Relevant news, schemes, events, and expert services

01 · The challenge

Farmers had to piece together advice, prices, products, and support from disconnected sources.

Existing apps addressed individual tasks, but everyday decisions still depended on local shops, other farmers, family members, and several digital services.

For Cargill, the product opportunity was to create one dependable point of access to crop guidance, market information, weather, and farming services.

My design challenge was to make that breadth understandable for farmers with different reading abilities and levels of smartphone experience.

01

Services were scattered

Prices, weather, crop care, and buying or selling were available in different places.

02

Farming apps were rarely used

Only 10% of the farmers surveyed used an agriculture app.

03

Trust was essential

Farmers needed clear information before spending money or treating a crop.

02 · Research

Field evidence defined what the first release needed to solve.

I combined farmer interviews, observation, survey responses, and competitive research to understand both practical needs and the barriers to adopting another farming app.

Design implication: farmers already used Facebook, WhatsApp, YouTube, and a few farming apps. Reusing familiar patterns and plain language would lower the effort required to learn Digital Saathi.

Primary persona

Meet Rudrappa

Rudrappa, the primary farmer persona
50 years · Karnataka

Maize farmer

He wants nearby crop prices, local weather, and clear help when a crop becomes unhealthy.

Frustrations

  • He depends on his son to use a smartphone.
  • He is unsure whether crop prices are fair.
  • Buyers change prices based on crop quality.
  • Expert advice is not always available nearby.

Goals

  • Find the nearest market and current crop price.
  • Check earlier prices before deciding when to sell.
  • Ask an expert about crop disease and treatment.

Interview highlights

What farmers told us.

Q

Can you easily get good seeds and fertiliser?

A

Good products cost more and are not always available nearby.

Q

What is difficult when you sell your crop?

A

Prices change often. I do not always know if I am getting a fair price.

Q

Who helps you when insects or disease harm the crop?

A

I ask other farmers or the local agriculture officer.

Q

How do you know that a crop is unhealthy?

A

I look for changes in the leaves and plant. If I am unsure, I ask an expert.

Competitive research

No single competitor covered the complete farming journey.

I compared Plantix, DeHaat, AgriCentral, and BigHaat across diagnosis, market prices, community, inputs, and weather. Each product solved part of the problem; the gap was a coherent service that connected those needs.

What this changed

  • Prioritise the farmer problems supported by both field and competitive evidence.
  • Connect high-value services through one predictable product structure.
  • Make reliability, transparency, and clear language requirements across every service.

Farmer perspective

Empathy Map

Synthesising what farmers thought, felt, said, and did kept the product focused on fair value, crop health, and access to dependable advice.

Shared focusFarmer needs and goals

Research questions

How Might We

I translated the recurring needs into opportunity questions so the team could explore solutions without committing to features too early.

How might we

make the app easy to hear and read?

How might we

connect farmers directly with producer groups?

How might we

show local market prices clearly?

How might we

help farmers improve their crop practices?

How might we

help farmers identify pests and crop disease quickly?

03 · Ideate

Turn field evidence into a focused first release.

Research produced more opportunities than one release could support. I used prioritisation to define the essential feature set, then organised it into a structure farmers could learn.

01

Feature prioritisation

MoSCoW Method

MoSCoW separated essential farmer needs from useful later additions. Market prices, Crop Doctor, weather, selling, news, and the forum formed the core first-release proposition.

Design system

A familiar visual language reduced learning effort.

Noto Sans, the product-green scale, compact feedback patterns, and familiar mobile controls supported readability across varied literacy and smartphone experience.

04 · Solution

A priority problem from the research:

Help farmers move from a crop symptom to actionable guidance.

Crop Doctor turns a complex diagnostic process into four understandable steps: select a crop, take or upload a photo, wait for analysis, and review the likely disease and treatment.

Select crop→Take or upload photo→Model checks disease→View solution
How it works

Present an AI result with appropriate caution.

  1. DAE field teams collected thousands of crop-disease photos from different angles and lighting conditions.
  2. The photos were labelled in the content management system and resized from high resolution to 224 × 224 pixels.
  3. A convolutional neural network learned the shapes, colours, and visual patterns linked to each disease.
  4. When a farmer uploads a new photo, the model compares it with the patterns learned from the earlier images.
  5. Testing produced about 80% accuracy, so the result is shown as guidance rather than a final expert diagnosis.
Version 1

The original flow established the diagnostic journey; usability testing then revealed where farmers needed more guidance and treatment detail.

Digital Saathi Crop Doctor Version 1 screens

Usability findings

  • Some farmers found it difficult to move through the flow.
  • Farmers wanted treatment options, organic controls, and clear quantity guidance.
Version 2

The second iteration responds directly to those findings with onboarding, clearer crop selection, photo editing, detailed treatment guidance, quantity calculation, and enquiry history.
