Agricultural Engineering is a discipline of engineering that applies engineering skills to improve agricultural production and processing. The primary concern of agricultural engineering is to solve the problems of providing food and fiber for the people of world. These problems include labor intensive methods of agricultural activities, less sophisticated agricultural machinery, age old sowing and harvesting techniques as well as lack of efficient irrigation systems and drainage practices. All these problems result in less yields which that raise serious questions on food security.
The agricultural productivity depends upon biological, hydrological, chemical and mechanical inputs. Mechanization is the most important among the four major inputs for crop production. Agricultural mechanization is the process which involves the use of agricultural machinery to increase the yield dynamically. Agricultural mechanization grips the use of tools, implements, and machines for agricultural land development, land preparation, crop production, harvesting, and storage and on-farm practices. Proper utilization of agricultural tools, implements and machines is covered under agricultural mechanization. Today agricultural mechanization has made several difficult jobs easy which were carried out by humans or animals in the past. Moreover, efficient agricultural machinery increases the production by decreasing the costs of production. Mechanization also ensures a higher quality due to increased precision. Unskilled labor often causes reduction in yield and quality, mechanization solves this problem.
Soil and water are vital natural resources that sustain agriculture. The vigilant use of these natural resources is indispensable for food security and environmental protection. Wastage of water and soil is major problem in developing and under developed world and it gets intensified in a scenario when water is scarce. Efficient utilization of these resources is one of the major stakes of agricultural engineering. Different techniques like highly efficient micro irrigation, water harvesting, moisture management, green manuring are adopted to conserve water while gully plugging, check damming, stop washing and wind breaking are some commonly used practices to prevent soil erosion.
The Department of Agricultural Engineering supports the missions of PMAS-Arid Agriculture University, Rawalpindi through its commitment to acquire, integrate and disseminate basic and applied knowledge about Conservation Engineering, Water Resource Development, Farm Mechanization, Farm Machinery, and Equipment Management issues in an ever changing world. We train undergraduate students from all Majors of B.Sc (Hons.) Agriculture to help solve these problems related to water conservation and farm mechanization.
A more specific mission of Department of Agricultural Engineering is to deliver quality education and extend knowledge for the amelioration of agriculture.
