New Superior Varieties are one component of technology to increase the productivity of food crops. Ex-Coal Mined Land is marginal land, and can be used for agriculture by applying location-specific technology. The purpose of this study was to determine the performance and productivity of hybrid corn: Bima-20, Bisi-2, NK-22 and Nasa-29 on ex-coal mining land. The study was conducted on the ex-coal mined land in Kutai Kartanegera Regency, East Kalimantan Province from April to July 2018. The technology applied was through Integrated Crops Land Management (ICLM) and was designed in the form of 4 replications randomized block design (RBD) consisting of 4 hybrid corn varieties treatment, namely Bima-20, Bisi-2, NK-22 and Nasa-29. Data collected includes plant growth and yield components. The results showed that maize Bima-20, Bisi-2, NK-22 and Nasa-29 were able to adapt on the ex-coal mined land, although it was not yet in accordance with the potential yield. Productivity of each variety (dry shelled): Bima-20 = 6.8 t ha −1 , Bisi-2 = 7.2 t ha −1 , and NK-22 = 7.1 t ha −1 and Nasa-29 = 7.9 t ha −1 .
