GATE Syllabus for Agriculture GATE which stands for Graduate Aptitude Test for Engineering is one of the toughest test, an all India Examination that basically test the comprehensive understanding of various undergraduate subjects in Engineering and Technology. It is jointly conducted by Indian Institute of Science and seven IIT’s on behalf of National Coordination Board-GATE, MHRD, Govt. of India, Department of Higher Education. GATE Score can be of great help like it can be used to take admission in various Post-graduate programmes. It may be used by Public sector units for employment screening purposes.
Agricultural Engineering which applies knowledge of biological science ,engineering science and technology to agricultural production and processing.It relates various discipline like mechanical,civil,electrical ,chemical engineering with animal and plant biology.There are four major specialization in agricultural engineering and each has unique and wide scope for research work.There is scarcity of agricultural engineers in private as well as in public sectors.Agriculture is one of the most important sector that contributes around 23% of GDP and give employment to 70% of the work force. Development and growth of Indian Economy is greatly dependent on agriculture and other allied activities.The prime task of agricultural engineers is to improve farming techniques and agricultural products and for that only they combine both engineering and biological science principles in order to make farming effortless, efficient and profitable.A person requires good intellect and a wish to make a difference to future farming.
