DEPARTMENT OF FARM MACHINARY
The Department of Farm
Machinery Engineering offers the degrees of Bachelor of
Science (B.Sc.) and Master of Science (M.Sc.) in Farm Machinery.
Research Activities
The department is involved in research in the various
aspects of farm power and machinery. Due
to the diverse nature of agriculture and the position of agricultural industry
in Iran, the scope of the research at the department is wide and varied.
Solving common problems of water, plant, soil, and animal environments has
provided a unique situation of multi-disciplinary research and scientific
cooperation between this department and other departments at the College of
Agriculture.
Areas of research include tillage systems for crop
production, soil compaction, deep tillage, physical properties of agricultural
materials and products, farm machinery performance evaluation, farm machinery
design, agriculture machinery systems planning and management, agricultural
mechanization extension as well as precision tools.
Energy is a major concern of modern world economy.
Consumption of energy in agricultural production for the various operations of
planting and soil preparation constitutes a large portion of agricultural
production costs. Therefore, optimum utilization of farm equipment and
machinery and the design of new ones are the research concerns and integral
parts of agricultural engineering and mechanization. The department of Farm
Machinery at IUT is committed to helping the promotion of the engineering
aspect of agriculture in the region. The followings are the main research
subjects of the department:
- Effects of
conventional and non-conventional (non-inversion, minimum tillage, no-tillage,
surface tillage) systems on soil physical characteristics and crop yields under
both arid and semi - arid conditions
- Impacts of
subsoiling practices on soil physical characteristics
- Effects of
different planting methods on crop yield under dryland and irrigated conditions
- Evaluation and
comparison of traction performance by various tractors; and draft requirements
of different farm machinery
- Comparing field
performance of various machines for forage production and harvesting
- Evaluation of
combine harvesting of cereal crops under field conditions
-Planning and
evaluation of machinery systems for major crops of central Iran including potato, sugar beets, wheat,
rice and vegetables.
Educational and
Research Facilities
The department has in its possession all kinds of farm
machinery currently used in modern agriculture. These are used for field study
performance under local conditions. The Fremont
Tractor Test Center evaluates the tractors used on farms in the region. The
center enables researchers to monitor current performance of power units on
farms. A Draft Sensing and Measuring
Unit is also available at the department. It determines the draft
requirements of various farm machines for different soils and crops. Plint Engine Test Station is mainly an
educational unit but it is also involved in studying the application of
different fuel sources in different engines. The station is fully computerized
and provides information with regard to engine performance characteristics
under various loads and working conditions.
UNDERGRADUATE
PROGRAM
Undergraduate students must take a total of 138-140 credits
of which 20 credits are the general courses, 37 credits are the basic ones, 74
credits the core courses and 7-9 credits the elective ones.
