This study compares the growth of two forage rice cultivars (Oryza sativa L.), Mogwoo and Mogyang, in Midwest reclaimed land (Seongmun Tide Embankment, Korea) for two years to find the most adaptable cultivars and the appropriate harvest time. In the case of high salinity soil, it was confirmed that the influence of precipitation was relatively high on soil condition and crop growth. In Mogyang, plant height and culm length tended to decrease slightly as the precipitation increased. As for the tiller number, Mogyang was higher than Mogwoo, but the leaf area was about 1.5 to 2 times higher in Mogwoo than in Mogyang. In addition, in both cultivars, dry weight increased rapidly during the dough stage, and Mogyang was 1538 and 1815 g/m2, respectively, while Mogwoo was 2090 and 2752 g/m2, which was significantly higher. Mogyang had a CP of 4.8%, a TDN and RFV of 59.4%, 94.0, respectively, and Mogwoo had a CP of 9.7%, a TDN and RFV of 60.1%, 103.8, respectively, resulting in Mogwoo having higher values, and in particular Mogwoo was found to have better forage quality in the milk stage than in the dough stage. In addition, in terms of soil and climate conditions in Midwest reclaimed land, it was confirmed that the Mogwoo variety was the most suitable compared to Mogyang, and dry weight was higher in the dough stage than in the milk stage, but it was concluded that high forage quality could be obtained by harvesting during the milk stage.

This research was conducted to select the most suitable winter forage crop varieties for silage in reclaimed land located in the Midwest of Korea by investigating the soil environment, crop growth characteristics, dry weight, and forage value according to growth stage. The slightly alkalescent soil was characterized by a pH of 7.41–7.84, by an electrical conductivity (EC) of 1–2.5 dS/m, and by 440–934 mg/kg of available phosphate. Barley showed the highest chlorophyll content in the heading stage and milk stages, while oats and triticale reached the highest content in the milk and dough stage. In both years, triticale achieved the highest leaf area index (LAI), reaching 4.3–4.8. In addition, triticale showed the highest percentage of dry matter and the highest dry weight in the milk stage. Forage value was the best in the heading stage for all cereal crops; however, its quality decreased as the growth stage proceeded. This study suggests cultivating triticale, which showed high adaptability to reclaimed soil and climatic conditions, as well as good growth and dry weight when harvested between the milk and dough stages. These results indicate that triticale can be cultivated all year round in salty soil and these data can be useful to increase forage production in reclaimed soil. [ABSTRACT FROM AUTHOR]
