Agricultural Engineering

agricultural engineering

Agricultural engineers apply their knowledge of engineering technology and biological science to design agricultural machinery, equipment and structures. They also develop ways to conserve soil and water and help improve the processing of existent agricultural products.

Graduates in this stream of engineering help improve crop production systems, design animal facilities, test machinery and analyze food production systems. They should be able to work well in teams as they often have to work in groups with other engineering graduates, and not necessarily those only of this field.

Admission for a Bachelor of Technology (B.Tech.) in Agricultural Engineering requires a solid background in mathematics, and also sound knowledge of science subjects like biology, chemistry and physics. Knowledge of English, social studies, computer literacy and humanities also play an important role. Most bachelor’s degree engineering programs usually have a duration of four years.


Agriculturists can find jobs as scientists, researchers, farm managers, head green keepers, project directors, product design engineers, senior agricultural managers, research analysts, agronomists, farming consultants or as subject matter specialists. Self employment is another option which graduates can consider.

Some colleges may require presentation of a seminar, industrial training or project work.

The final semester of most colleges has project work, along with three to four subjects, which may be electives. The subject pool students can choose from depends upon the faculty, resources and the facilities in each college, and may vary.

Electives under soil and water engineering include reservoir and pond design, wasteland management, minor irrigation, integrated watershed management, and environmental engineering. Farm machinery and power engineering electives may include subjects like human factors, farm machinery management, system engineering, manufacturing processes of agricultural machinery and agricultural mechanisation.Elective subjects that come under agricultural process and food engineering include beverages technology, food packaging technology, food laws and legislation, fermented food products and entrepreneurship in the food industry.
