땅콩 수확시기 및 첨가제에 따른 땅콩경엽의 수량 및 사일리지용 사료가치를 비교 조사하였던 바 그 결과를 요약하면 다음과 같다. 1. 수확시기별 생육은 개화후 90일 수확시 경엽의 병해(갈색무늬병 및 흑색무늬병) 발생 정도가 낮고, 성숙협비율은 89%, 100립중은 81g으로 높았다. 2. 수확시기에 따른 경엽 및 종실 생산성은 개화후 90일에 경엽은 52 t/ha, 종실중은 3.6 t/ha이었다. 3. 경엽과 종실수량간에는 고도의 정상관(r2 =0.62** )이 있었다. 4. 땅콩경엽의 사일리지 사료가치는 땅콩경엽+볏짚+젖산균 조제시 ADF 42.2%, NDF 49.6%, CP 10.5%, TDN 55.6%이었다. 5. 땅콩경엽 사일리지의 유기산함량은 땅콩경엽+볏짚 및 땅콩경엽+보릿짚에다 젖산균 첨가시 각각 산도 5.04 및 5.10, 낙산함량 3.12% 및 4.64%, 젖산함량은 7.34% 및 2.07%이었다.
To investigate the effects of Harvesting time and additives on the quality of peanut silage, the silage was mixed in combination with peanut leaf and stem, rice and barley straw, inoculant etc. Harvesting time at peanut growth stage was the best at 90 days after flowering with 30 branches,81 g of 100-seed weight, and 77% of shelling rate with low diseases in leaf and stem. By delay of harvest, diseases and lodging were increased. The yield of forage was the highest at 90 days after flowering as 52 t/ha, and seed yield was at 110 days as 3.72 t/ha. The yields between forage yield and seed yield (r2 =0.62** ) were correlated positively. The value of silage as a forage came over 90 days after flowering in combination with peanut leaf+stem+vice straw+inoculant treatment. The treatment was increased dry matter (DM) yield and neutral detergent fiber (NDF), the coarse protein (CP), and total digestible nutrient (TDN) content of silage in comparing with control (peanut leaf+stem). The pH at the organic matter contents of silage in combination of peanut leaf+stem+rice straw+lactic acid treatment was 5.04 to 5.10, the content of butyric and lactic acid were 3.12 to 4.64%, 2.07 to 7.34%, respectively.y.
