College of Agricultural Engineering and Technology

In backdrop of the existing policy for agricultural development in Bihar, necessity was felt for intervention of engineering and technological aspects in agriculture and therefore, the Govt. of Bihar took decision to establish a College of Agricultural Engineering in the main campus of the then Rajendra Agricultural University, Pusa in the state of Bihar. College of Agricultural Engineering (CAE) was established on 7th December, 1983 under Rajendra Agricultural University for imparting education, conducting research followed by transfer of technologies to the farmers and entrepreneurs, and later rechristened as College of Agricultural Engineering and Technology (CAET) in 2022. CAET got accredited by National Agricultural Education Accreditation Board (NAEAB) w.e.f. 28th March 2022. The college, thus aims to support the agriculture of the State as well as country in wider prospective by way of intervention of engineering related technologies in production and post-production systems, so as to make the agriculture profitable and sustainable in long run.


To create a unique teaching-learning environment through technical education and scientific research in the discipline of agricultural engineering; to produce technical experts, researchers and entrepreneurs passionate to serve our farmers and industries.


  • To impart new knowledge among agricultural engineering graduates by engaging in rigor academic curriculum, innovative research and industrial training.
  • To produce exemplary researchers and educators through quality education and cutting-edge research in postgraduate programmes.
  • To identify the regional and national researchable issues for achieving sustainable food production by undertaking collaborative projects with academia and industry.
  • To disseminate appropriate agricultural technologies to the farming communities and industries.


  • Research and teaching shall be carried out with honesty, maintain the highest standards of ethics.
  • Accountable to all the stakeholders including students, faculties, staffs and alumni.
  • Transparency shall be maintained among all academic and research activities.
