The agricultural sector is focused on the food sector, the availability of paddy as the basic ingredient of rice. The need for food is a "basic need" for every farmer. The increased food production can be reached through the programs of land productivity improvement (intensification) and expansion of agricultural land (extension).. The purposes of this study were: 1) to analyze the effect of price on the rice supply in South Kalimantan, 2) to predict the elasticity value of rice supply in short and the long terms in South Kalimantan. The study was conducted from February to August 2016. Data used in the study was secondary data with time series for 19 years starting from 1996-2015. Time series data are data that illustrate the development over time. To be able to predict the model of supply response, the price data of rice at the farmer level, price of fertilizer, area of rice planting and productivity of rice were used. Data were obtained through library study, and from related institutions or agencies, such as the Department of Agriculture in South Kalimantan Province, the Central Bureau of Statistics, and the State Logistics Agency (Bulog) South Kalimantan, through direct interviews and questionnaires. Data were analyzed using Nerlove model. The results showed that: 1) the area of ​​rice planting was affected by the prices of rice and fertilizer in the previous year, 2) the productivity of rice was influenced by the rice price and productivity in the previous year, 3) the supply response of rice to the planting area and productivity generally was pretty good because the free variable was able to explain 91.6% of the dependent variable for the planting area and 96.0% for the productivity, 4) the elasticity of the supply response of rice to the price in the short term and the long term was inelastic, 5) the farmers in South Kalimantan could not respond to the price changes to the maximum because the results of the elasticity indicated that the farmer response to the prices was very low, 6) it is recommended to carry out further study by adding the data from longer period of time, 7) the price policy made by the government for the farmers had no effect or only had a very small response from the farmers in South Kalimantan, and it is therefore recommended to carry out the expansion of rice planting area to increase the rice production in ​​South Kalimantan.
