Corn has a very significant contribution in the national economy as one of main food crop commodities. As a strategic commodity, corn has big potency even in covid-19 pandemic time, corn relatively resilient compare to other commodities in Central Sulawesi. However the level of corn productivity will relate to the adoption of technology and the farmers’s choices to cope with risk, both production and marketing. Therefore, the study aims to know farmers’s choices to corn farming risk management strategies. A survey had been conducted to 75 respondents across the three districts in Sigi Central Sulawesi, and a quantitative analysis approach was applied in the study. Data were analyzed using descriptive and multinomial logit analysis. The result showed that mostly of the corn farmers have no spesific risk management strategy due to the limit of information and awareness. While a second number already aware but not use spesific strategies. The rest of respondents have adopted certain strategies for managing risk but not compensatory for marketing’s risk yet. Some farmers gave credence to engage with the not formal contract or middleman as buyers and supplier for the production input and thus, becoming vulnerable position for the farmers. Variables that significantly gave effect on the choice of risk management strategies are: education, farm size, activity in farmer group, alternative commodity, and propensity to take a risk.

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.
