초록

This study was conducted to evaluate the productivity of whole crop silage wheat utilizing the paddy fields during a couple of years from 2019 to 2021 in Suwon, Korea. This investigation was used the two maturity types of wheat cultivar ‘Cheongwoo’ (early) and ‘Taeu’ (late). The heading date of 2nd year (Oct. 2020 to May. 2021) cultivation was delayed about 11 to 13 days by more than 1st year (Oct. 2019 to May. 2020). The growth characteristics were shown that the plant height was increased in 2nd cultivation, while the number of culms and the panicle part ratio were decreased. Moreover, the nutritive value of ‘Cheongwoo’ and ‘Taeu’ were also decreased in 2nd cultivation. These changes have thought to a difference of the precipitation by cultivation years. Because, the precipitation during the period from the end of winter dormancy to the harvesting stage in 2nd (337 mm) cultivation was more about twice than 1st (169.3 mm) cultivation. However, the dry matter yield of ‘Cheongwoo’ was not shown a statistical difference by cultivation years, while ‘Taeu’ was shown to decrease tendency. The total dry matter yield regardless of the cultivation years were higher in ‘Cheongwoo’ than ’Taeu’, and especially ’Cheongwoo’ was more 3 tons per hectare (15.3 t/ha) than ‘Taeu’ (12.6 t/ha) at 2nd cultivation (p<0.01). The trend of dry weight in ‘Cheongwoo’, early mature type, showed a relatively high ratio of dry matter (p<0.05) was considered that due to a high panicle ratio by a fast heading and an adequate weight of panicles by a sufficient maturing. In conclusion, selecting the early maturity cultivars could achieve a higher and more stable total dry matter yield considering the cropping system in the central region. Furthermore, it also has the advantage of being able to double-cropping system with forage rice, which has considered the maximum whole-crop forage production year-round. These results suggest that the ‘Cheongwoo’ be optimum cultivar to produce the year-round forage on paddy fields in the central region.
