Farm Power & Machinery (Q1–23): The largest opening cluster — tractors, tillage implements, PTO, traction, engines, harvesting/threshing equipment, and field efficiency. Heavy focus on numerical/applied parameters (speeds, ratios, percentages).
Soil & Water Conservation / Irrigation Engineering (Q24–41): A substantial block covering soil-water relationships (field capacity, wilting point), irrigation methods and efficiency, watershed structures (check dams, terraces, contour bunding), and runoff/hydrology.
Land Levelling & Surveying (Q42–48, 96): A smaller but distinct thread on benchmarks, weirs, plastic limits, and levelling — practical surveying/geotechnical skills.
Food & Post-Harvest Process Engineering (Q49–82): The single largest cluster in the paper — covers rheology (Newtonian/non-Newtonian fluids), drying methods, thermal processing/sterilization, refrigeration, food safety standards (HACCP, ISO 22000), and processing equipment.
Renewable Energy (Q83–95): A well-defined block on solar (PV, collectors, radiation), biogas, wind energy, and micro/pico-hydro systems — testing both concepts and quantitative benchmarks (Betz limit, methane %, efficiency ranges).
Irrigation System Design (Q96–100): Closing questions on drippers, command area classification, and sprinkler uniformity — tying back to applied irrigation engineering.
Key trends noticed:
- Food and post-harvest engineering is the dominant theme (~30 questions), suggesting this paper weighs processing/food engineering more heavily than classical farm machinery.
- Numerical/parameter-based recall questions dominate (specific speeds, temperatures, percentages, ranges) rather than conceptual derivations — testing applied/practical knowledge over theory.
- Renewable energy is a notably strong, modern addition (13 questions), reflecting current emphasis on solar, biogas, and micro-hydro in agricultural engineering curricula.
- Classical soil-water-irrigation engineering remains a core pillar, consistent with the discipline’s agronomic roots.
