What Does the Odisha AAO Syllabus Cover in 2026?
The notified Odisha AAO syllabus is a two-paper Agriculture syllabus at bachelor’s degree level. Paper I concentrates on production systems, horticulture, plant health and allied disciplines; Paper II brings together soil science, seed and crop improvement, extension, economics, statistics and farmer empowerment. Candidates should treat Annexure-A to Advertisement No. 06 of 2025-26 as the controlling syllabus.
The syllabus is for direct recruitment to Assistant Agriculture Officer in the Odisha Agriculture and Food Production Service under the Department of Agriculture & Farmers’ Empowerment. It is not a generic state-service syllabus, so preparation should follow the unit names notified by OPSC rather than importing subjects from other AAO examinations.
| Paper | Primary coverage | Marks |
|---|---|---|
| Paper I | Production, horticulture, plant protection and allied areas | 100 |
| Paper II | Soils, seed and breeding, extension, economics and farmer empowerment | 100 |
Odisha AAO Exam Pattern and Marking Scheme
The written examination consists of two MCQ papers totalling 200 marks. Each paper has 100 questions, one mark for a correct answer and a two-hour duration. An incorrect response attracts a 0.25-mark deduction, while an unattempted question has no deduction.
| Parameter | Notified arrangement |
|---|---|
| Paper I | 100 questions, 100 marks, 2 hours |
| Paper II | 100 questions, 100 marks, 2 hours |
| Question type | Objective multiple-choice questions |
| Wrong answer | 0.25 mark deducted |
| Unattempted question | No deduction |
| Personality Test | 25 marks |
OPSC may fix qualifying marks for individual papers and for the written total by category. The advertisement says candidates meeting those marks are shortlisted for the Personality Test from written-exam performance; document verification occurs before that test. The select list uses aggregate marks out of 225.
Paper I Syllabus: Crop Production, Horticulture and Protection
Paper I groups applied production and crop-health areas into four units. Revise every named topic from the official list, then use question practice to test recall and application. OPSC does not publish a unit-wise question count in the syllabus, so fixed topic weightage should not be assumed.
| Unit | Official topics |
|---|---|
| Unit I | Agronomy; farming system and sustainable agriculture; principles of organic farming; crop production technology |
| Unit II | Production technology of horticultural fruit, vegetable and floriculture crops |
| Unit III | Plant pathology and microbiology (disease): field crops, horticultural crops, entomology, and nematode pests of horticultural crops and their management |
| Unit IV | Agriculture and sericulture; agro-meteorology and climate change; forestry |
Start with agronomy and crop production, pair each horticulture crop group with its production practices, then revise disease, insect and nematode management alongside the relevant crop. Keep separate short notes for climate, sericulture and forestry so that the smaller listed areas are not missed.
Paper II Syllabus: Soils, Seed, Breeding, Extension and Economics
Paper II combines scientific and farm-management subjects in four units. It moves from soil and nutrient concepts to seed technology, genetics, extension, agricultural economics, statistics, business and farmer empowerment. This arrangement supports a revision plan built around linked concepts rather than isolated chapters.
| Unit | Official topics |
|---|---|
| Unit I | Geoinformatics and nano-technology; fundamentals of soil science; soil fertility and nutrient management; problematic soils and their management |
| Unit II | Principles of seed technology; genetics and plant breeding; introductory crop physiology |
| Unit III | Fundamentals of agricultural extension education; agricultural economics; fundamentals of statistical methods; agri-business management; agricultural marketing, trade prices |
| Unit IV | Agriculture heritage; farmer empowerment schemes |
Organise revision by concept chains: soil properties to fertility and problem-soil management; seed quality to genetics and breeding; then extension communication to economics, marketing and statistics. Use the official terminology in your checklist so every listed topic is covered before full-paper practice.

How to Use the Odisha AAO Syllabus for Focused Preparation
The dependable approach is to turn Annexure-A into a checkable study plan. This prevents over-reading areas that do not appear in the notification and makes each revision round measurable.
- Open the official advertisement and mark every Annexure-A topic in a two-paper checklist.
- Divide Paper I into crop production, horticulture, crop health and allied-subject blocks.
- Divide Paper II into soils, seed and breeding, extension-economics and heritage-scheme blocks.
- Make short formula and fact sheets for statistics, nutrient management, marketing terms and crop protection.
- Practise objective questions with the notified 0.25-mark penalty in mind.
- Check the official portal before each milestone for notices that supersede earlier information.
