Assessment of weather events impacts on forage production trend of sorghum-sudangrass hybrid

This study aimed to assess the impact of weather events on sorghum-sudangrass hybrid (<italic>Sorghum bicolor</italic> L.) cultivar production trend in central inland region Korea during monsoon season, using time series analysis. The data collected between 1988 and 2013 were compiled along with year’s data. growing degree days (GDD), accumulated rainfall, sunshine duration used their impacts forage (kg/ha) trend. Conversely, GDD rainfall had positive negative effects production, respectively. Meanwhile, such as heavy typhoon also based warnings Korean season. did not affect even increasing frequency intensity rainfall. Therefore, for was forecasted slightly increase until 2045. predicted 2045 will be 14,926 ± 6,657 kg/ha. It is likely that damage by typhoons can reduced through more frequent harvest against short-term single a deeper extension root system soil erosion lodging. an environment rapidly changing due climate change extreme/abnormal weather, cultivation would advantageous securing stable robust production. Through this study, we propose one alternative summer options achieve dynamically monsoon, spite rather lower nutrient value than maize (<italic>Zea mays </italic>L.).
