Compare threshing and combine harvesting mechanisms and compute cylinder speed, throughput and grain loss percentages.

Explain sprayer and duster components and calculate nozzle discharge, spray volume per hectare and calibration drift.

Select matching implements for a given tractor horsepower and justify the match with draft and power requirement calculations.

Interpret tractor PTO and drawbar test data to derive maximum drawbar power and specific fuel consumption.

Describe cleaning and grading equipment (air-screen cleaner, indented cylinder, specific gravity separator) and state the property each exploits.

Compute moisture content on wet and dry basis, convert between the two, and calculate moisture removed during drying.

Explain thin-layer and deep-bed drying, and compute drying time and air requirement for a given grain load.

Outline milling, parboiling and oil extraction steps for paddy, pulses and oilseeds, naming the key machines.

Design a storage plan stating safe moisture, bag vs bulk options and aeration needs for paddy and maize.

Compute soil loss using the Universal Soil Loss Equation and identify which factor changes under terracing or contour bunding.

Design contour bund and bench terrace spacing using land slope, rainfall and soil erodibility inputs.

Calculate irrigation water requirement from reference evapotranspiration and crop coefficient, and convert to a canal or pump discharge.

Compare surface, sprinkler and drip irrigation for water use efficiency and compute drip system emitter numbers and operating hours.

Size a farm pond and compute storage volume from catchment runoff using a runoff coefficient.

Evaluate pump selection: compute total head, friction loss and pump power, and place the duty point on a system curve.

Compare farm structure types (gable, monitor, quonset) and select roofing and orientation suited to Assam rainfall and humidity.

Compute ventilation rate and design a ventilated grain or produce store controlling temperature and relative humidity.

Explain environmental control hardware (fans, evaporative cooling pads, psychrometric chart use) and read wet-bulb and dry-bulb states.

Compute biogas yield from cattle dung and size a family-size digester, stating retention time and gas demand.

Compare solar PV, solar thermal and biomass options for farm loads, and calculate PV array size and battery capacity for a pump or lighting load.

Explain precision agriculture components: GPS/GNSS accuracy classes, variable rate application, yield mapping and remote sensing indices such as NDVI.

Apply ICT tools in extension: mobile advisory, e-NAM, soil health card data and farm management apps, and judge which fits a small Assam holding.

Interpret a simple yield map and prescribe a variable rate fertiliser plan.

Identify tractor and machinery hazards and apply ROPS, PTO guarding and hitch safety rules to specific scenarios.

Explain pesticide handling, storage and first aid, and select correct PPE for spraying and grain handling.

Build a cost of operation sheet for a farm machine covering fixed and variable costs, depreciation and break-even hectares.

Draft a short agri-business plan: product, market, capital, subsidy schemes and a cash flow for one enterprise.

Revise all domain formula sheets and re-solve missed numericals under timed conditions.

Take two full-length mock tests and log every wrong answer by domain and error type.

Close the three weakest domain gaps identified from mock results with targeted practice.

Rehearse short written answers on safety, ICT and entrepreneurship, which carry steady marks but are often underprepared.
