The adaptation of new superior varieties on new rice field in Central Sulawesi

Abstract

One way to increase productivity in new rice field is through adaptation of new superior varieties. The purpose of this study was to obtain 1-2 new locally adaptive superior varieties in a new field rice. The study was conducted in Sirom Village, Lamala District, and Banyataya Village, East Luwuk District, Banggai Regency. The experimental design used was a Random Factorial Pattern Group Design. The treatment consists of two factors; the first factor is two technological packages, namely 1) Jarwo super technology, and 2) existing technology. The second factor was four superior varieties of rice (Inpari 34, Inpari 35, Banyuasin, and Mekongga as control treatments. The adaptation observation includes growth aspects in the form of plant height and number of tillers. The results showed that there had been changes in plant growth even though still not optimal. The control varieties namely Mekongga could not grow in the two research locations while the best results were obtained from the treatment of using Inpari 34 followed by Banyuasin variety with Jarwo Super technology. Yields and generative components of plants showed a significant effect of Jajar Legowo Super technology, introduction of new superior varieties (VUB) and its interactions.
