초록

본 시험은 강원 영서지역에서 겨울사료작물(IRG 및 트리티케일)과 여름사료작물(사료용 벼) 이모작 시 양질 조사료의 최대 수량 생산 작목조합을 알아보기 위해 수행하였다. 겨울사료작물의건물률은 IRG ‘코윈어리’가 평균 29.6%로 트리티케일 ‘조성’의평균 35.5%보다 낮았다. 평균 생체수량은 ‘코윈어리’가2,662kg/10a, ‘조성’이 2,836kg/10a로 두 작목 간 통계적으로 유의적인 차이가 없었다. 평균 건물수량은 트리티케일 ‘조성(996kg/10a)’이 IRG ‘코윈어리’(696kg/10a)보다 많았다. 여름사료작물인 사료용 벼의 건물률은 ‘조농’이 평균 34.5%, ‘조우’가평균 35.0%로 유의적인 차이가 없었다. 평균 생체수량은 ‘조우’ 가 5,367kg/10a로 ‘조농’의 3,966kg/10a보다 많았다. 또한 평균건물수량도 ‘조우(1,936kg/10a)’가 ‘조농(1,433kg/10a)’보다 많았다. 겨울사료작물인 트리티케일 ‘조성’을 10월 중순에 파종하여이듬해 5월 하순에 수확한 후 여름사료작물인 사료용 벼 ‘조우’ 를 6월 상순에 이앙하는 조합으로 2,982kg/10a의 최대 건물 생산량을 얻을 수 있었다.

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.
