In order to establish optimal double cropping system for getting the maximum annual productivity, we investigated annual fresh and dry yields of winter forage crops (WFC), Italian ryegrass (IRG) ‘Kowinearly’, triticale ‘Joseong’ and summer forage crop (SFC), ‘Jonong’ and ‘Jowoo’ as whole crop silage rice in the paddy field of Yeongseo of Gangwon Province. The double cropping of each crops was applied with 2 standard cultivation method of WFC and SFC from 2018 to 2020. For the WFC, the average percentage of dry matter (29.6%) of IRG ‘Kowinearly’ was lower than that (35.5%) of triticale ‘Joseong’. The average fresh matter yield of IRG ‘Kowinearly’ was 2,662kg/10a that there was no significant difference from the 2,836kg/10a of triticale ‘Joseong’. The average dry matter yield (996kg/10a) of triticale ‘Joseong’ was more than that (696kg/10a) of IRG ‘Kowinearly’. For the summer forage crops, the average percentage of dry matter of whole crop silage rice, ‘Jonong’ was 34.5% that there was no significant difference from the 35.0% of ‘Jowoo’. The average fresh matter yield (5,367kg/10a) of ‘Jowoo’ was more than that (3,966kg/10a) of ‘Jonong’. And the average dry matter yield (1,936kg/10a) of ‘Jowoo’ was more than that (1,433kg/10a) of ‘Jonong’. The total maximum dry matter yield was 2,982kg/10a with the combination of the WFC triticale, ‘Joseong’ and the SFC whole crop silage rice, ‘Jowoo’. In conclusion, the combination of crops that can obtain the maximum yield of high quality forage for double cropping is sowing the WFC triticale, ‘Joseong’ in mid-October, harvesting ‘Joseong’ around the end of May and then SFC whole crop silage rice, ‘Jowoo’, to be transplanted in early June.
