Abstract
The success of cultivation of a crop commodity is influenced by many factors, one of which is the choice of plant varieties to be developed. The selection of superior varieties of a plant that is developed will greatly determine the success of a crop cultivation business. One way to increase corn productivity is to plant high-yielding and adaptive corn VUBs with the local environment. The presence of an adaptive VUB, both free and hybrid, can significantly contribute to increasing productivity or national corn production. To find out the adaptive corn VUB in Buton District, it is necessary to do an Adaptation Study of Corn VUBs on dry land in Buton Regency. This study used a randomized block design (RBD), with 4 corn VUBs, namely Nasa 29, Bima 20 URI, Sukmaraga and Lamuru which were repeated 6 times. The results showed that the adaptability of corn VUBs planted in Buton District was quite good. Overall, the four VUBs are able to adapt to local conditions, this can be seen from the yield production better when compared to local varieties that have been commonly grown by local farmers. The average productivity of each corn VUB planted was Nasa 29 (6.90 t / ha), Sukmaraga (6.50 t / ha), Lamuru (6.02 t / ha) and the lowest was the Milky 20 URIs (5, 87 t / ha).
