수수 x 수단그라스 교잡종 논토양 재배시 품종별 생육특성 및 사료가치 비교 연구 = A Comparative Studies on the growth Characteristics and Feed Components of Sorghum x Sudangrass hybrids at Paddy Field Cultivation

다국어 초록 (Multilingual Abstract)

This study was carried out to compare the agronomic characteristics, forage yield, and feed value of nine sorghum*sudangrass hybrids at paddy field cultivation. The nine recommended sorghum*sudangrass hybrids used in this study were P877F, Cow pow, Turbo gold, Maxi graze, Jumbo, G7, Sweet home, Honey chew BMR and Green star. Plant height, leaf number, stem diameter, and stem hardness were higher in Jumbo than other varieties (P<0.01). Sugar content (brix) was higher in order of P877F ＞ Sweet home ＞ maxi graze ＞ Green star ＞ Cow pow ＞ G7 (P<0.01). Fresh (86,199㎏/ha) and dry matter yield (16,206 ㎏/ha) of Jumbo were higher than other varieties (P<0.01). Crude protein was the highest in Maxi graze (6.5%), but crude fat was the highest in Honey chew BMR as 2.1% (P<0.01). NDF and ADF of Jumbo and G7 were higher than other varieties (P<0.01). TDN was higher in order of Maxi graze ＞ Sweet home ＞ P877F ＞ Honey chew BMR ＞ Green star, but no significant differences were found among the varieties. Minerals were the highest in Cow pow (15,020.5 ㎎/㎏), and Sweet home (6,222.6 ㎎/㎏) was the lowest as compared to other varieties (P<0.01). Total amino acids were higher in order of Maxi graze ＞ Sweet home ＞ Turbo gold ＞ Honey chew BMR ＞ Jumbo (P<0.01).
Crude protein yield and crude fat yield were the highest in Turbo gold (814.6 ㎏/ha) and Honey chew BMR (309.8㎏/ha), respectively (P<0.01). Mineral yield was the highest in Cow pow as 207.6 ㎏/ha (P<0.01). Amino acid yield (592.2 ㎏/ha) and TDN yield (10,194 ㎏/ha) were the highest in Sweet home. Based on the above results, sorghum * sudangrass hybrid varieties should be selected on the basis of the purpose of use. Because, each varieties showed various growth characteristics and nutrition yield (protein, fat, mineral, amino acid, TDN).

본 시험은 수수*수단그라스 교잡종 논토양재배 시 품종별 생육특성 및 사료적 가치를 규명하기 위하여 실시하였으며, 공시재료는 추천품종 9품종을 공시하였다. 초장, 엽수, 경의 굵기 및 경경도에 있어서는 Jumbo가 다른 품종에 비하여 유의적으로 높은 수치를 나타냈다(P<0.01). 당도는 P877F ＞ Sweet home ＞ Maxi graze ＞ Green star ＞ Cow pow ＞ G7 순으로 높게 나타났으며, 생초수량과 건물수량에 있어서는 생육특성이 좋았던 Jumbo 품종이 각각 86,199 ㎏/ha 및 16,206 ㎏/ha으로 다른 품종에 비하여 가장 높은 수량성을 보였다(P<0.01). 조단백질 함량은 Maxi graze가 6.5%로 가장 높게, 조지방 함량은 Honey chew BMR이 2.1%로 가장 높게 나타났다(P<0.01). 그리고 Jumbo와 G7 품종은 NDF 및 ADF 함량이 높은 품종으로 나타났다(P<0.01). TDN 함량은 품종 간에 유의적인 차이를 보이지 않았다. 무기물 함량은 Cow pow ＞ Turbo gold ＞ Jumbo ＞ Honey chew BMR ＞ G7 순으로 높게 나타났으며, 총구성 아미노산 함량은 Maxi graze ＞ Sweet home ＞ Turbo gold ＞ Honey chew BMR ＞ Jumbo 순으로 높게 나타났다. 단백질 생산량 및 지방 생산량은 각각 Turbo gold (814.6 ㎏/ha) 및 Honey chew BMR (309.8 ㎏/ha)이 가장 높게 나타났으며(P<0.01), 광물질 생산량은 Cow pow 품종이 207.6 ㎏/ha로서 높게 나타났다(P<0.01). 구성 아미노산 생산량과 TDN 생산량은 Sweet home 품종이 각각 592.2 ㎏/ha 및 10,194 ㎏/ha로 가장 높게 나타났다(P<0.01). 이상 결과를 종합해 보면 수수*수단그라스 교잡종을 논토양에서 재배 시 생육특성 및 각종 영양수량이 다양하게 나타남으로서 품종 선택은 이용 목적에 따라 선택 재배하는 것이 바람직할 것으로 생각된다.
