Engineering Drawing: Students learn technical representation, dimensions, projections and machine drawings.

Computer Programming: Programming supports data analysis, automation, sensors, simulation and decision tools.

Principles of Soil Science: Students learn soil texture, structure, moisture, fertility and physical behaviour.

Crop and Horticultural Fundamentals: Engineers need basic knowledge of crops, planting requirements, growth cycles and field operations.

Fluid Mechanics: Fluid Mechanics examines pressure, flow, energy, pipes and hydraulic machines.

Open-Channel Hydraulics: This subject deals with water flow in canals, channels and field systems.

Engineering Hydrology: Students study rainfall, runoff, infiltration, evaporation, groundwater and water balance.

Irrigation Engineering: Irrigation Engineering covers crop water requirements, water conveyance, application methods and scheduling.

Soil and Water Conservation Engineering: This subject addresses erosion, runoff control, water harvesting and land treatment.

Watershed Management: Watershed Management examines the integrated use of land, water and vegetation within a drainage area.

Groundwater and Well Engineering: Students study aquifers, wells, pumping, drawdown and groundwater recharge.

Farm Power: Farm power can come from human labour, animals, engines, tractors, electricity and renewable systems.

Tractor and Automotive Engines: This subject covers internal-combustion engines, fuel systems, transmission, traction and tractor performance.

Theory of Machines: Students study mechanisms, motion, forces and machine components.

Farm Machinery: Machinery subjects cover tillage, sowing, planting, interculture, spraying, harvesting and threshing equipment.

Machinery Design: Engineers apply design principles to shafts, gears, bearings, frames, blades, metering systems and other components.

Agricultural Structures: Students learn the design and environmental requirements of storage, livestock, greenhouse and farm-service buildings.

Post-Harvest Engineering: Post-Harvest Engineering addresses cleaning, grading, drying, storage and handling.

Crop-Processing Engineering: This area applies engineering operations to cereals, pulses, oilseeds and other produce.

Food and Dairy Engineering: Programmes may include heating, cooling, separation, refrigeration, processing and equipment used in food and dairy systems.
