Crops like paddy, rice and Raagi (millet) were being cultivated at small scale in the area with irrigation from numerous lakes in the area. The villages surrounding Yelahanka, especially Allalasandra, was famous for Guava fruit and grapes. Alas, now the agriculture and farming exist no more due to urbanization and industrialization.
Governmental research facilities exist around Yelahanka in the form of Gandhi Krishi Vigyana Kendra (GKVK) under the University of Agricultural Sciences www.uasbangalore.edu.in/ and Central Institute of Medicinal and Aromatic Plants (CIMAP – www.cimap.res.in) under Council of Scientific and Industrial Research (CSIR).
