Abstract

This study was carried out to investigate the growth characteristics, yield and chemical compositions of corn hybrids for silage according to ridging times in the paddy field cultivation. The experimental design was arranged in a randomized block design with five treatments and three replication. The ridging times of five treatments were untreated (C), 7 leaves (T1: 31 days), 8 leaves (T2: 37 days), 9 leaves (T3: 42 days) and 10 leaves stage (T4: 48 days after sowing) of silage corn. The ridging treatments (T1, T2, T3, T4) were higher (p<0.01) dry matter yield and TDN yield than the unridging treatment (C). However, there were no significant differences among T1, T2, T3 and T4 treatments. The Crude protein content of unridging treatment was decreased (p<0.01), while NDF content was increased (p<0.01) compared to ridging treatments. The contents of mineral and amino acid in ridging treatments were higher than unridging treatment (p<0.05, p<0.01). In particular, mineral and amino acid contents were the highest in T4 and T1, respectively (p<0.01). Based on the above results, ridging work is to be increased the yield quantity and nutritional value of silage corn. And the best result was obtained in T4 treatment of ridging treatments.

본 연구는 사일리지용 옥수수를 파종 한 후 7엽기, 8엽기, 9엽기 및 10엽기에 각각 배토작업을 실시하여 무배토 처리구와 생육특성, 수량성 및 화학적 특성을 비교 검토하여 배토 효과 및 배토처리 시기에 따른 증수 효과를 구명하기 위하여 실시하였다. 배토처리구들(T1, T2, T3 및 T4)은 무배토구(C)에 비하여 건물수량, TDN 수량이 증수되는 것으로 나타났으나 (p<0.01), 배토시기(T1, T2, T3 및 T4)에 따라서는 유의적인 차이가 나타나지 않았다. 그리고 배토구들은 무배토구에 비하여 조단백질 함량은 증가하고 NDF 함량은 떨어지는 것으로 나타났다(p<0.01). 무기물 및 구성아미노산 함량에 있어서도 무배토구에 비하여 배토를 실시한 구에서 높게 나타났다(p<0.05, p<0.01). 그러나 무기물에 있어서는 배토시기에 따른 유의적인 차이를 보이지 않았지만, 구성아미노산에 있어서는 7엽기에 배토를 실시한 T1구에서 높게 나타났다. 건물수량, TDN수량, 단백질함량, 무기물함량 및 구성아미노산 함량을 종합해 볼때, 무배토에 비하여 배토처리가 증수효과가 있는 것으로 나타났으며, 특히 배토시기에 있어서는 10엽기에 배토를 실시한 T4구가 가장 좋은 것으로 나타났다.
