Abstract

This study was conducted to evaluate on agronomic characteristics, dry matter (DM) and digestible dry matter (DDM) yields of summer sowing sorghum hybrids (Sorghum bicolor (L) Moench) at Seongju in Gyeongbuk from 2013 to 2014. The experiment was arranged in randomized complete block design with three replications. Sorghum hybrids were seeded $31^{st}$ of July, 2013 and 2014. Sorghum hybrids were harvested on $3^{rd}$ November, 2013 and $5^{th}$ November, 2014. The observed average heading date was October 5, 8 and 9 for Sordan79, Sprint and SX17 respectively. The DM yield of 'SX17', 'Sordan79', and 'Sprint' was 24.2, 23,9 and 23.4 ton/ha, respectively and DM yield of those were significantly higher (p<0.05) than other three cultivars in 2013. DM yield of 'SX17', 'Sprint' and 'Sordan79' was 20.8, 20.0 and 19.3 ton/ha, respectively and DM yield of those was significantly higher (p<0.05) than other three cultivars in 2014. The DDM yield of 'SX17', 'Sordan79', and 'Sprint' was also higher (p<0.05) than other three cultivars in 2013 and 2014. ADF content of sorghum hybrids was low, whereas DDM was high. The results of this study indicated that traditional sorghum-sudangrass hybrids ('SX17', 'Sordan79') and sudan grass-sudangrass hybrid ('Sprint') than late flowering sorghum-sudangrass hybrid ('PACF8350') and sorghum-sorghum hybrids ('SS405', 'Sugar grazer') would be recommended for DM and DDM yields in the southern Korea.

본 시험은 2013년부터 2014년까지 경북 성주에서 여름 파종 수수류 교잡종의 생육특성, 품질 및 수량성을 평가하기 위하여 실시하였다. 시험설계로 품종을 처리로 한 6처리 3반복으로 배치하였다. 파종기는 2013년과 2014년 7월 31일에 조파하였고 수확은 2013년 11월 3일과 2014년 11월 5일에 하였다. 출수기는 2년 평균이 sordan79 10월 5일 sprint 10월 8일 SX17 10월 9일 순으로 조사되었고, 2013년 수수류 교잡종의 DM수량은 SX17, Sordan79 및 Sprint 가 각각 24.2, 23.9 및 23.4톤/ha으로 SS405, PACF8350 및 Sugar grazer 21.5, 20.6 및 20.5톤/ha 보다 높았으며 (p<0.05), DDM수량 역시 비슷한 경향을 보였다. 2014년 DM수량은 SX17, Sordan79 및 Sprint가 20.8, 19.3 및 20.0톤/ha로 다른 3품종 보다 높았으며(p<0.05), DDM수량 역시 비슷한 경향을 보였다. ADF와 NDF의 함량은 비교적 낮았으며 반면에 DDM 함량은 높아 사료가치가 우수하였다. 본 시험의 결과에 의하면 여름 파종 시 전통형(출수형) 수수-수단그라스 교잡종 SX17, Sordan79와 수단그라스-수단그라스 교잡종 Sprint가 늦은 개화형(비출수형) 수수-수단그라스 교잡종 PACF8350이나 수수-수수교잡종 SS405와 Sugar grazer 보다 수량측면에서 남부지방에서 유리할 것으로 생각된다.
