Abstract
본 시험은 가축분 퇴비 시용조건에서 수수$\times$수단그라스 교잡종(Sorghm bicolor (L.) Moench)의 시용수준별, 생육시기별, 잎과 줄기 부위별 질산태 질소 함량과 당토 및 가축 채식률 등을 구명하고자 Pioneer 988 품종을 공시하여 1995년도에 실시하였다. 가축분은 톱밥과 50:50으로 섞은 발효분으로 시용수준은 ha당 우분 퇴비 50, 100, 150톤, 돈분 퇴비 20, 40, 80톤, 계분 퇴비 10, 20, 40톤을 파종 보름전 시용하였으며, 각각 무비구(대조구)를 두고 파종은 ha당 30kg의 종자를 휴폭 50cm로 조파하였다. 수수$\times$수단그라스 교잡종의 질산태 질소 함량은 가축분 퇴비 시용구에서 무비구인 대조구 (평균 228mg/kg)에 비해 높았으며(P<0.05), 또 가축분 퇴비 시용수준이 높아짐에 따라 평균 질산태 질소 함량은 397, 512, 609mg/kg으로 유의적으로 증가하였다(P<0.05). 생육시기별 질산태 질소 함량은 초장 50~60cm, 100~120cm, 200~220cm일 때 각각 평균 438, 454, 418mg으로 비슷한 수준이었다. 또 질산태 질소 함량은 가축분 퇴비 종류에 관계없이 줄기(376mg/kg)가 잎(135mg)에 비해 크게 높았으며(P<0.05), 잎에서는 하부 잎(151mg)이 상부 잎(58mg)에 비해 현저히 높았고 (P<0.05), 줄기에서도 아래부위로 갈수록 질산태 질소 함량은 유의적으로 증가하여 상부위, 중간부위, 하부위에서 각각 357, 511 및 610mg이었다.(P<0.05). 수수$\times$수단그라스의 당도는 가축분 퇴비 시용구에서 대조구(평균 4.9。)에 비해 낮았으며 (P<0.05), 또 가축분 퇴비 시용수준이 높아짐에 따라 평균 당도는 4.9, 4.4, 4.3。로 유의적으로 감소하였다(P<0.05). 본 시험에서 대체적인 당도의 범위는 4~5。 범위였으며, 생육시기별 당도는 초장 50~60cm와 100~120cm에서는 평균 3.9。로 낮았으나 초장 200~220cm일 때는 평균 6.1。로 크게 높아졌다. 가축 채식률은 가축분 퇴비 시용구에서 무비구인 대조구(평균 76.1%)에 비해 낮았으며(P<0.05), 또 가축분 퇴비 시용수준이 높아짐에 따라 평균 채식률은 73.9, 58.7, 52.3%로 크게 감소하였다. A field experiment was carried out to determine the effect of application level of animal manure on the nitrate nitrogen concentration, sugar content and animal intake of forage sorghum $\times$ sudangrass hybrid (Sorghum bicolor (L.) Moench, cv. Pionee. 988) in 1995. The application amount of animal manure were 50, 100 and 150MT in cattle manure, 20, 40 and 80MT in swine manure, and 10, 20 and 40MT/ha in poultry manure. Non-application plot(control) was involved. The nitrate nitrogen concentration was increased with increasing of application level of animal manure(P<0.05). Average nitrate nitrogen concentration was 397, 512, and 609mg/kg at low, medium and high application level of animal manure. The nitrate nitrogen concentration by plant height was 438mg/kg at 50~60m of plant height, 454mg at 100~120cm, and 418mg at 200~220cm. The nitrate nitrogen concentration of stems was 376mg, and significantly higher than that(135mg) of leaves(P<0.05) regardless of animal manure type, and lower parts of stems and leaves were significantly higher than those of upper parts of plants(P<0.05). Average nitrate nitrogen concentration of leaves was 151mg at lower, and 58mg at upper parts of plants, and the concentration of stems was 357mg at lower, 511mg at middle, and 610mg at upper parts of plants. The sugar contents of sorghum $\times$ sudangrass hybrid was decreased with increasing of application level of animal manure(P<0.05). Average sugar content was 4.9, 4.4, and 4.3。 at low, medium and high application level of animal manure. The sugar content by plant height was 3.9。 at 50~60 and 100~120cm of plant height, and 6.1。 at 200~220cm of plant height. Animal intake of sorghum $\times$ sudangrass hybrid was decreased greatly with increasing of application level of animal manure. Average intake was 73.9, 55.7, and 52.3% at low, medium and high application level of animal manure. The intake by animal manure type was 73.7% in cattle, 59.7% in swine and 62.5% in poultry manure.
