1. Crop Science — 25 Marks (Start Here)
This is the single largest subject — one in every four questions comes from Crop Science. Mastering this alone puts you ahead of most candidates.
What Exactly is Asked?
Questions typically test:
- Which crop belongs to Kharif/Rabi/Zaid?
- What is the scientific name of wheat/rice/sugarcane?
- What is the seed rate of mustard per hectare?
- Which crop is UP #1 in producing?
- What is the spacing for sugarcane planting?
How to Prepare Crop Science
Step 1: Master Crop Classification
This is the foundation. Every agriculture aspirant must know this cold:
| Season | Months | Major Crops | Sowing | Harvesting |
|---|---|---|---|---|
| Kharif | Jun-Oct | Rice, Maize, Bajra, Jowar, Arhar, Cotton, Sugarcane, Soybean | June-July | Oct-Nov |
| Rabi | Nov-Mar | Wheat, Barley, Mustard, Gram (Chana), Pea, Potato, Linseed | Oct-Nov | Mar-Apr |
| Zaid | Mar-Jun | Watermelon, Muskmelon, Cucumber, Moong, Sunflower | March | May-June |
Make a table for each crop with: scientific name, family, origin, seed rate, spacing, major varieties grown in UP, and India ranking. This table format helps in last-minute revision.
Step 2: Focus on UP-Specific Crops
UPSSSC specifically asks about crops grown in Uttar Pradesh:
| Crop | UP's India Rank | Key Districts |
|---|---|---|
| Wheat | #1 | Agra, Aligarh, Meerut, Muzaffarnagar |
| Sugarcane | #1 | Muzaffarnagar, Meerut, Saharanpur, Sitapur, Lakhimpur Kheri |
| Potato | #1 | Agra, Farrukhabad, Firozabad, Kannauj |
| Mango | #1 | Lucknow (Malihabad), Varanasi, Saharanpur |
| Milk Production | #1 | Across UP (buffalo dominant) |
| Rice | #2 | Eastern UP — Gorakhpur, Maharajganj, Siddharthnagar |
| Jute | — | Bahraich, Maharajganj, Deoria, Gonda |
Pro tip: Siddharthnagar is famous for Kalanamak rice — a fragrant variety. This is a popular exam question.
Step 3: Learn Agronomic Practices
Understand the differences between:
- Crop Rotation — Alternating crops season to season (wheat → rice → wheat)
- Mixed Cropping — Growing two crops together randomly (wheat + mustard)
- Intercropping — Growing two crops in alternate rows systematically
- Relay Cropping — Second crop sown before the first is harvested
- Mono Cropping — Same crop every season (risk of soil exhaustion)
- Dry Farming — Farming without irrigation (depends on rainfall)
Step 4: Crop Production Techniques
For each major crop, know: land preparation → seed treatment → sowing method → fertilizer dose → irrigation schedule → weed management → harvesting → yield per hectare.
Focus on wheat, rice, sugarcane, mustard, and potato — these 5 crops cover most questions.
On AgriDots, the Agronomy section under Agriculture covers all these topics with interactive lessons, <mark class="agridots-imp"> tagged exam facts, and AI-powered voice revision that teaches you crop-by-crop in Hindi.
2. Soil & Water Management — 10 Marks
What is Asked?
- Name the nutrients deficient when leaves turn yellow
- What type of soil is found in Bundelkhand?
- What percentage of N is in Urea?
- What are the methods of soil conservation?
How to Prepare
Soil Types — Memorize with Regions:
| Soil Type | Where in UP | Key Crops |
|---|---|---|
| Alluvial (Bangar = old, Khadar = new) | Gangetic Plain (largest area) | Wheat, Rice, Sugarcane |
| Red & Yellow | Bundelkhand, Mirzapur | Coarse grains, Pulses |
| Laterite | Parts of southern UP | Limited cultivation |
| Sandy | Western UP (semi-arid) | Bajra, Pulses |
Nutrient Deficiency — The Visual Symptoms Table:
This is one of the most frequently asked topics. Create a single-page chart:
| Nutrient | Deficiency Symptom | Affected Part |
|---|---|---|
| Nitrogen (N) | Yellowing of older leaves (chlorosis) | Lower/older leaves first |
| Phosphorus (P) | Purple/reddish coloring | Older leaves |
| Potassium (K) | Leaf tip/margin scorching (necrosis) | Older leaves |
| Iron (Fe) | Interveinal chlorosis | Younger leaves first |
| Zinc (Zn) | Khaira disease in rice | Young leaves |
| Boron (B) | Hollow stem in cauliflower | Growing points |
| Calcium (Ca) | Blossom end rot in tomato | New growth |
Key rule: Mobile nutrients (N, P, K, Mg) show deficiency in older leaves first. Immobile nutrients (Fe, Mn, Zn, B, Ca) show in younger leaves first.
Fertilizer NPK Content — Must Memorize:
| Fertilizer | N% | P% | K% |
|---|---|---|---|
| Urea | 46% | 0 | 0 |
| DAP | 18% | 46% | 0 |
| MOP (Muriate of Potash) | 0 | 0 | 60% |
| SSP | 0 | 16% | 0 |
| Ammonium Sulphate | 20.5% | 0 | 0 |
| NPK Complex | 12 | 32 | 16 |
Bio-fertilizers — Know the Organism and Crop:
| Bio-fertilizer | Organism Type | Fixes/Solubilizes | Used With |
|---|---|---|---|
| Rhizobium | Bacteria | Nitrogen | Pulses (symbiotic) |
| Azotobacter | Bacteria | Nitrogen | All crops (free-living) |
| Azospirillum | Bacteria | Nitrogen | Cereals, grasses |
| PSB (Phosphate Solubilizing Bacteria) | Bacteria | Phosphorus | All crops |
| Mycorrhiza (VAM) | Fungi | Phosphorus | Tree crops, vegetables |
| Blue-green algae (BGA) | Cyanobacteria | Nitrogen | Rice (paddy fields) |
| Azolla | Fern + Anabaena | Nitrogen | Rice |

3. Biotechnology & Plant Breeding — 10 Marks
The Common Mistake
Most candidates spend too much time on deep genetics theory. The AGTA exam asks basic concepts, not research-level questions.
What to Focus On
Must Know:
- Mendel's 3 laws (Dominance, Segregation, Independent Assortment)
- Definition of: hybridization, heterosis (hybrid vigor), mutation breeding, pure line selection
- Photosynthesis: C3 vs C4 vs CAM plants (wheat = C3, maize = C4, pineapple = CAM)
- Plant hormones: Auxin (growth), Gibberellin (elongation), Cytokinin (cell division), Ethylene (ripening), ABA (stress)
- GM crops in India: Bt Cotton (only approved GM crop)
- Basic tissue culture concepts
Can Skip or Skim:
- Deep molecular biology, gene mapping, DNA sequencing details
- Complex Mendelian ratios beyond dihybrid cross
- Detailed biochemical pathways of respiration
