In 1930 the chair of Agrochemistry was transferred into the newly-established Armenian Agricultural Institute, in 1989 the Chair of Agrochemistry and Soil Science was established. And the chair of General Agriculture was founded in 1931. After the establishment of the Armenian Agricultural Academy (AAA) in 1994, chair of Agriculture was unified with the chairs of Soil Science and Agrochemistry and named as chair of General Agriculture.

In 2004 by the decision of the Scientific Council of Armenian Agricultural Academy the chair was named after the Academician G.Kh. Aghajanyan.

More than one thousand scientific articles, scientific booklets, methodological guidelines, monographs, text-books and manuals have been published by the chair pedagogical staff. The chair is one of the main scientific-methodical centers in our Republic that conducts researches in the fields of agriculture, soil science and agrichemistry.
Monographs by G. Aghajanyan and R. Manukyan are of great importance.
