This study aims to evaluate the CropSyst model in simulating the growth and production of Katokkon. The research was carried out from December 2018 to May 2019 in two stages: the first stage was in To’pao Village in Tana Toraja Regency and Tallang Sura Village in North Toraja Regency, and the second stage was in the Agro-climatology and Biostatistics Laboratory of the Department of Agronomy, Faculty of Agriculture, Hasanuddin University. The method used in this research was survey method and simulation method with CropSyst. The survey method was used to obtain information regarding some phenology and production of three Katokkon plant sources ie. Leatung 1, Leatung 2 and Limbong Sapolo. While the simulation method with CropSyst was carried out by incorporating all information obtained in the first stage to run the model. The results of this study indicate that the productivity of the Katokkon chili at the two study sites are similar to the output of the CropSyst model. Katokkon chili productivity in To’pao Village simulated by the model was 6.87 ton/ha while observed yield was 6.60 ton/ha. The productivity of the Katokkon chili in Tallang Sura Village were 6.74 and 6.63 ton/ha for the simulated and observed, respectively. Index of Agreement (d) at the two research locations shows that the CropSyst model can accurately predict the productivity of the Katokkon chili from Leatung 2 (d = 0.54) compared to the Katokkon chili from Limbong Sampolo (d = 0, 51) and Leatung 1 (d = 0.48).
Pulu mandoti is the local glutinous rice from Enrekang Regency with the advantage of distinctive odor and taste, which is not possessed by similar rice. The research aimed to of knowing the character of the local glutinous rice producing area of Enrekang (pulu mandoti). The research was conducted using a structured survey method. Data collection was conducted by observation in the field, analysis in the laboratory, documentation, and interviews of farmers. Soil sampling were conducted by purposive sampling where the determination of the wetland planted with glutinous rice can be determined through the making of a transect lines using a topographic map. The results showed that the best producers of pulu mandoti were in the Piawan Village, Kendenan Subdistrict with an average temperature of 21-25ºC, an average rainfall of ± 1,083 mm/yr, the elevation of 800masl and the slope of 10%. The texture of silt loam, silt clay loam, clay loam and sandy loam. Soil depth >98cm with pH of 5.5 - 6.4, CEC 16-25 cmol/kg, C-organic >2%, low salinity <0.25 dS/m and base saturation >35%. This research has a low of N- total content >0.2%, high of P-available 17 ppm, low of K2O <0.3 cmol/kg with average yield 440 kg/ha.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
