The Division of System Research and Engineering (DSRE) was created during March, 2021 by merging six disciplines viz. Agricultural Engineering, Agronomy, Agro-forestry, Horticulture, Soil Science and Water Management. The disciplines of DSRE have made outstanding contributions for development of hill agriculture in the North Eastern Hill regions of India. The major research focus of this division is to develop sustainable hill agriculture through basic/applied research in the fields of natural resource management, organic farming, horticulture and mechanization. The Division is collaborating with the natural resource management, horticulture and agricultural engineering scientists of six regional centers of the institute located in Arunachal Pradesh, Manipur, Mizoram, Nagaland, Sikkim and Tripura who are coordinating with the respective state governments.

The division is also continuously providing technical help and other consultancy services to all the stakeholders of the region. Keeping pace with International developments made in the subject as well as looking into regional (NER) priorities, significant contributions have been made through a number of research projects undertaken in different areas of natural resource management including soil and water, acid soil amelioration, conservation agriculture, Jhum improvement, integrated farming systems, organic farming, packages of practices for agriculture and horticulture crops, agroforestry, improvement and development of horticulture crops, collection, evaluation, conservation and utilization of genetic resources of important horticultural crops, post-harvest management, value addition, farm mechanization, geospatial tools development, contaminated soil management, soil testing and fertilizers recommendation, compost and vermicompost, climate resilient technologies, etc.
