Agronomy
Q: What is alternate bearing in mango? How is it managed?
Answer: Alternate bearing is when mango trees produce a heavy crop one year (ON year) and negligible crop the next (OFF year). It is the biggest productivity constraint in mango cultivation.
Causes: Depletion of carbohydrate reserves after a heavy crop year; insufficient time for vegetative recovery.
Management:
- Paclobutrazol (soil drenching, 4–5g a.i./tree) — regulates flowering, synchronises bearing
- Ethephon spray — promotes off-season flowering regulation
- Proper NPK nutrition — NPK 1:1:1 ratio for young trees; shift to high K and P at bearing stage
- Deblossoming (remove 50% panicles in ON year) — helps balance

Q: What crops are grown in Kharif and Rabi seasons? Give examples.
| Season | Period | Key Crops |
|---|---|---|
| Kharif | June–October (sown with monsoon onset) | Rice, Maize, Jowar, Bajra, Cotton, Groundnut, Soybean, Arhar |
| Rabi | October–March (sown after monsoon) | Wheat, Mustard, Gram, Barley, Peas, Linseed |
| Zaid | March–June (short summer) | Cucumber, Watermelon, Muskmelon, Moong |
Tip: Always know 4–5 crops per season and their states of production (e.g. Wheat → UP, Punjab, Haryana; Rice → WB, UP, AP).
Q: What is Integrated Pest Management (IPM)?
Answer: IPM is a sustainable pest control approach combining multiple methods to keep pest populations below economic threshold levels without heavy reliance on chemical pesticides.
Components:
- Cultural methods — crop rotation, resistant varieties, intercropping
- Biological methods — use of natural enemies (Trichogramma, ladybird beetle)
- Mechanical methods — pheromone traps, light traps, physical removal
- Chemical methods — as last resort, using recommended doses
Why important for AFO: Banks finance crop insurance claims linked to pest damage. AFOs verify losses on ground.
Q: What is crop rotation? Why is it practised?
Answer: Growing different crops in succession on the same land across seasons/years.
Benefits:
- Breaks pest and disease cycles
- Maintains soil fertility (legumes fix atmospheric nitrogen)
- Controls weeds
- Reduces input costs
Classic example: Rice → Wheat → Legume (pulse) rotation in Indo-Gangetic Plains.
Q: Difference between biofertilizer and chemical fertilizer?
| Feature | Biofertilizer | Chemical Fertilizer |
|---|---|---|
| Source | Living microorganisms | Synthetic/mineral |
| Examples | Rhizobium, Azospirillum, PSB, Blue-green algae | Urea, DAP, MOP |
| Nitrogen source | Fixes atmospheric N₂ | Applied as fixed N |
| Cost | Low | High |
| Soil health | Improves | Can degrade over time |
| Residue | None | Salt accumulation possible |
Rhizobium fixes N in legume root nodules. Azotobacter is a free-living N-fixer for non-legumes.
Soil Science
Q: What is soil pH and why does it matter?
Answer: Soil pH measures acidity/alkalinity on a scale of 0–14. pH 7 = neutral; below 7 = acidic; above 7 = alkaline.
Optimal range for most crops: 6.0–7.5
Impact on nutrient availability:
- Acidic soils (pH <5.5): Al and Mn toxicity; P, Ca, Mg deficiency
- Alkaline soils (pH >8.5): Fe, Zn, Mn deficiency; poor P availability
Management:
- Acidic soils → add lime (CaCO₃)
- Alkaline/sodic soils → add gypsum (CaSO₄) + leaching
Q: What is the role of NPK in plant nutrition?
| Nutrient | Role | Deficiency Symptom |
|---|---|---|
| N (Nitrogen) | Vegetative growth, chlorophyll, protein | Yellowing of older leaves (chlorosis) |
| P (Phosphorus) | Root development, flowering, seed set | Purple/reddish coloration of leaves |
| K (Potassium) | Stomata regulation, drought resistance, grain filling | Marginal leaf scorch (necrosis) |
Exam tip: Most important nutrients for oilseeds and pulses = Sulphur (S) and Phosphorus (P) — a common IBPS AFO mains question.
Q: What is the Soil Health Card scheme?
Answer: Launched in 2015 by GOI, Soil Health Cards provide farmers with soil nutrient status reports for 12 parameters (N, P, K, pH, EC, OC, S, Zn, Fe, Cu, Mn, B) and fertilizer recommendations.
Cycle: Cards issued every 2 years.
AFO relevance: AFOs verify soil health data when sanctioning crop loans — ensuring appropriate crop selection and input financing.
Q: What is waterlogging? How does it affect crops?
Answer: Waterlogging = excess water in root zone, displacing soil air (oxygen deficit).
Effects:
- Root respiration inhibited → nutrient uptake drops
- Anaerobic conditions → toxic substances (methane, H₂S) accumulate
- Root rot, stunted growth, yield loss
Remedies: Surface drainage, sub-surface drainage (tile drains), raised beds, selection of tolerant varieties.
Horticulture
Q: What is tissue culture? Where is it used in agriculture?
Answer: Tissue culture = growing plant cells/tissues in sterile nutrient media in vitro to produce disease-free, uniform plants (clonal propagation).
Major uses:
- Banana, sugarcane, potato (virus-free planting material)
- Orchids, carnations (floriculture)
- Forest species (teak, eucalyptus) — mass multiplication
Advantage: Year-round production, large quantities, disease-free.
Q: Name important horticultural crops and their families.
| Crop | Family | Important Points |
|---|---|---|
| Mango | Anacardiaceae | National fruit; alternate bearing problem |
| Banana | Musaceae | Tissue culture propagation; Cavendish variety |
| Tomato | Solanaceae | Both vegetable and fruit botanically |
| Onion | Alliaceae | Kharif + Rabi; Maharashtra biggest producer |
| Muskmelon | Cucurbitaceae | Zaid crop |
| Guava | Myrtaceae | Highest Vitamin C among common fruits |
Animal Husbandry
Q: What is the approximate daily weight gain of a well-nourished crossbred calf?
Answer: 800–1000 grams per day (approximately). Pure indigenous breeds gain 300–400 g/day.
Q: Name important cattle breeds and their origin.
| Breed | Type | State/Origin |
|---|---|---|
| Gir | Dairy (Indigenous) | Gujarat |
| Sahiwal | Dairy (Indigenous) | Punjab/Rajasthan |
| Murrah | Buffalo (Dairy) | Haryana |
| Holstein Friesian | Exotic dairy | Netherlands |
| Jersey | Exotic dairy | Jersey Island (UK) |
Crossbred: HF × Indigenous = high milk yield + disease resistance.
Q: What is the Milk Production Mission / National Programme for Dairy Development?
Answer: NPDD provides financial assistance for creation of infrastructure for clean milk production, processing, and marketing. NABARD provides refinance.
Operation Flood (now Mission Flood): 3 phases (1970–1996), transformed India into world's largest milk producer. Model: cooperative dairy network (Amul model).
Fisheries
Q: What is aquaculture? Name common fish species cultured in India.
Answer: Aquaculture = controlled cultivation of aquatic organisms (fish, shrimp, molluscs, seaweed) in ponds, tanks, cages, or sea.
Common species:
- Freshwater: Rohu, Catla, Mrigal (IMC — Indian Major Carps), Tilapia, Pangasius
- Shrimp: Vannamei (Pacific white shrimp — dominant in AP/Odisha), P. monodon (tiger shrimp)
- Marine: Pomfret, Seer fish, Tuna
Blue Revolution: GOI scheme to double fish production and increase fishers' income. PMMSY (Pradhan Mantri Matsya Sampada Yojana) is the current flagship scheme.
Panel Behaviour Tips
- Agriculture Expert (Dr. Priya Mehta in config) will probe depth — if you give a textbook answer she will ask a follow-up: "Have you seen this in the field?"
- Regional Field Officer (Arun Patil) asks local crop questions: "What crops are grown in your district? What is the MSP of wheat this year?"
- Know MSPs of 5–6 major crops (announced annually by CACP)
- Know your home state's major crops, irrigation sources, and agri challenges

Frequently Asked Questions
Q: What agriculture questions are asked in the IBPS AFO interview? Agriculture carries 35% weight — the largest single topic. Common questions include: Kharif and Rabi crop lists, soil pH management, NPK deficiency symptoms, IPM components, the Soil Health Card 12 parameters, alternate bearing in mango, and biofertilizer vs. chemical fertilizer differences. The panel probes both textbook knowledge and field application.
Q: What is the Soil Health Card scheme and what does AFO need to know about it? Launched in 2015, the Soil Health Card provides farmers with nutrient status reports covering 12 parameters (N, P, K, pH, EC, OC, S, Zn, Fe, Cu, Mn, B) and gives crop-specific fertilizer recommendations. Cards are issued every 2 years. AFOs verify soil health data when sanctioning crop loans to ensure appropriate crop selection.
Q: What are common animal husbandry questions in the IBPS AFO interview? Panels ask about cattle breed origins (Gir from Gujarat, Sahiwal from Punjab/Rajasthan, Murrah buffalo from Haryana), exotic breeds (Holstein-Friesian, Jersey), Operation Flood and the Amul cooperative model, and NPDD (National Programme for Dairy Development). Knowing milk yield differences between indigenous and crossbred cattle is also tested.
Q: How does knowledge of agriculture help in the AFO role in a bank? AFOs use agriculture knowledge to verify crop loan applications (checking if the crop and area are genuine), assess repayment capacity based on expected yield, verify PMFBY crop loss intimations, and counsel farmers on input financing through KCC. The technical knowledge directly determines loan quality.
