Abstract. Wawan BP, Amin M. 2018. Development reseach of Lamuru maize in Kutai Kartanegara to support the production improvement in East Kalimantan. Pros Sem Nas Masy Biodiv Indon 5: 303-306. This development research on non-hybrid corn in Kutai Kartanegara was aimed to review the development of superior maize variety to improve the maize production in East Kalimantan. This research investigated the growth of Lamuru superior maize variety in Tenggarong Seberang, Kutai Kartanegara, East Kalimantan during the dry season in 2018. One planting hole was filled with single one-month old maize seed using 2:1 jajar legowo planting method within a planting gap of 40 x 20 x 80 cm, resulting in as many as 83333 plant population.
