Mixed expeller cake has been one of soil management to improve crop productivity and soil fertility. But, there was a little information on optimum mixed expeller cake application for chinese cabbage. So, in this study, we were evaluated the preplant optimum application rate of mixed expeller cake(MEC) in chinese cabbage cultivation at field. Treatments consist of control, inorganic fertilizer(N-P2O5-K2O : 320-78-198 kg ha-1), MEC(50, 100, 150% on preplant application standard 110 kg ha-1 as N, topdressing : 210 kg ha-1 as N). In results, growth characteristics was not significantly different. But, yield was increased when application rate was increased. And MEC 150% treatment showed similar yield as inorganic treatment. There was no significant difference in soil pH, OM, Av.P2O5, NH4-N and Ex.K. But, soil EC and NO3-N were increased when MEC level increased. As a results, MEC 150% can be proposed as preplant optimum application rate of MEC from this study. But abuse of MEC and long-term using caused about salt accumulation in soil. 유기질 비료 중 혼합유박은 작물생산성과 토양의 비옥도를 높일수 있는 농자재중 하나이다. 그러나 배추재배시 혼합유박의 적정시용량에 대한 연구는 미비한 실정이다. 이에 본 연구는 혼합유박의 밑거름 시용량에 따른배추의 생육, 수량 및 토양특성 변화를 확인하고 이를 통해 혼합유박의 밑거름 적정 시용량을 제시하고자 하였다. 본 시험은 무처리, NPK처리구(N-P2O5-K2O : 320-78-198 kg ha-1), 혼합유박 처리구는 밑거름을 질소기준 210 kg ha-1을 50, 100 및 150% 수준으로 기비하고 추비는 시기에 맞게 시비하는 것으로 설정하였다. 배추의 생육은 무처리구를 제외하고는 통계적 유의성은 없었으나, 수량의 경우 NPK 처리구 > MEC 150% 처리구 > MEC 100% 처리구> MEC 50% 처리구 > 무처리구 순이었다. 처리구에 따른 질소 이용 효율은 혼합유박 처리량이 증가할수록 증가하는경향이었다. 토양 특성의 경우 pH, OM, Av.P2O5, NH4-N 및 Ex.K의 경우 유의적인 차이는 없었으나 EC 및 NO3-N은혼합유박의 밑거름 시용량이 증가할수록 약간 증가하는 추세였다. 이를 통해 수량을 위한 혼합유박 밑거름 적정시용량은 밑거름 150% 처리인 것으로 판단된다.

본 연구는 조사료 생산 분야에서 화학비료를 사용하는 관행농법에서 벗어나 유기재배 기술개발을 위하여 관행재배와 유기재배의 수량성, 사료가치 등을 비교 조사하였다. 시험은 전남 강진군 작천면 소재 축산연구소 의논에서 수행하였다. 유기질 비료로는 질소성분이 4.0% 함유된 유박비료를 이용하였으며, 시험구 편성은 대조구(Con)와 대조구 질소 함량 기준으로 환산하여 유박비료 100% 처리구(T1), 유박비료 150% 처리구(T2), 유박비료200% 처리구(T3)로 구성 하였다. 시험품종은 수수×수단그라스 교잡종(SX17)을 5월 25일에 ha당 40kg 을 휴립세조파(조간 50㎝)로 파종하였다. 수확기 처리구별 초장은 대조구 317㎝, T1 252㎝, T2 269㎝, T3 293㎝으 로 대조구가 가장 우수하였고, 시비 처리구에 따른 시험구에서는 시비량의 증가에 따라 증가하였고, 건초량은 대조구 11.386kg/ha, T1 6,015kg/ha, T2 6,799kg/ha, T3 7,627kg/ha으로 초장의 생육과 동일한 경향을 보였다. 조단백질은 대조구 7.0%, T1 5.7%, T2 6.3%, T3 5.1%로 시험 처리구에서는 T2에서 가장 높았다. 이와 같은 결과로 유박비료를 대조구 시비량 질소 함량 대비 150% 시비에서 사료가치는 유의적 차이를 보이지 않았으나, 초장과 건초량이 증가가 이루어졌으므로 150% 기준으로 시비하는 것이 적합할 것으로 판단된다. This experiment was carried out to compare the productivity and feed value between standard cultivation and organic mixed expeller cake fertilizer cultivation to develop organic cultivation technology except from standard cultivation using chemical fertilizers in the field of forage production. This study was conducted in the rice field of Livestock Research Institute Jacheon-myeon, Gangin-gun Jellanam-do. Organic mixed expeller cake fertilizer consists of 4.0% nitrogen, 65% castor, 30% seeds and 5% fish meal. Sorghum-Sudangrass Hybrids(SX17) was sowed 40kg per hectare on May 25. Test group formation was consisted of a standard group and test treatment. The standard group(Con.) was fertilized chemical fertilizer according to the N-P-K kg/ha, 200-150-150 (basal 100kg, uptake 100kg). Test treatment was carried out organic fertilizer 100%(T1), organic fertilizer 150%(T2) and organic fertilizer 200%(T3) according to the nitrogen content of standard group(Con.). Plant height of harvest time depending on the treatment was that Con was 317㎝, T1 was 252㎝, T2 was 269㎝ and T3 was 293㎝. Dry matter yield was that Con was 11,386kg/ha, T1 was 6,015kg/ha, T2 was 6,799kg/ha, T3 was 7,627kg/ha. In the test treatment, plant height and dry matter yield increased with increasing fertilizer. Crude protein was the height in Con(7.0%) and Crude protein of test treatment was T1(5.7%), T2(6.3%), and T3(5.1%). As a result of this study, T2 was recommended.

친환경 벼 재배농가에서 혼합유박비료를 관행적으로 이앙 3일 전에 사용함에 따라 분얼 기 이후에 비료효과가 나타나므로 수량이 감소하는 문제를 해결하기 위해 본 연구를 수행 하였다. 실내에서 조사한 혼합유박비료의 무기화는 담수조건에서 7주까지 NH4-N가 증가하 였고, 비담수 조건에서 5주까지 NO3-N가 증가하였다. 벼 이앙 20일에 논토양의 질소무기화 는 이앙 20일 전 처리구가 0.85%로 가장 높았다. 수확기 토양특성은 혼합유박비료 시비시 기에 따라 토양유기물함량을 제외하고 차이가 없었다. 이앙 60일에 초장, 간장, 수장은 이 앙 20일 전 처리구가 가장 길었다. 또한 이앙 20일 전 처리구에서 수수, 등숙비율, 천립중이 높게 나타나 백미수량이 관행처리(이앙 3일 전)에 비해 9% 증가하였다. 백미의 백도와 amylose는 차이가 없었지만, 단백질 함량과 식미치는 이앙 20일과 30일전 처리에서 같은 수 준이었다. 쌀 수량과 품질 등을 혼합유박비료 시용시기와 관계식으로 산출하면 혼합유박비 료의 적정 사용 시기는 이앙 21.3일 전으로 나타났다. The aim of this study was to solve the problem of yield loss causing the lag of fertilizer efficiency after tiller stage, being originated by applying mixed expeller cake fertilizer on three day before rice transplanting in organic rice farmers. The mineralization degree of NH4-N of the mixed expeller cake fertilizer was increased until 7 weeks at flooding condition, and so did NO3-N until 5 weeks at nonflooding condition. The mineralization rate of nitrogen in paddy soil on 20 days before rice transplanting was the highest by 0.85% on 20 days before the transplanting treatment. The properties of yields during the harvest period have no difference with application time of the mixed expeller cake fertilizer, except soil organic matter. The plan length, culm length and panicle length were the longest on 20 days before rice transplanting. Also, the number of tiller, ripening rat and 1,000 grain weight were the highest on 20 days before rice transplanting, and thereby the yield of white rice were increasing by 9% on 20 days before rice transplanting compared with that of 3 days before rice transplanting. The whiteness values of the rice and amylose content made no difference, but the value of protein and palatability were the same between 20 days and 30 days treatment. In the conclusion, the relationship between rice yield, its quality and application time of the mixed expeller cake fertilizer has showed that the suitable time of applying it reveals 21.3 days before rice transplanting.

This study was carried out to investigate the optimal application rate and time of mixed expeller cake (MEC) for the replacement of chemical fertilizer. Dongjin-1, as cultivated rice was used at Fluvio-marine deposit in Honam plain paddy field. Soil chemical properties were improved by the application of MEC. Contents of total nitrogen and organic matter were higher in 70%, 100% plots of basal dressing than standard fertilizer application (SFA) plot. Cation exchangeable capacity was highly increased in 70% plot of basal dressing. Also, the content of organic matter in soil was increased with MEC application. Cation exchangeable capacity, total nitrogen and available hosphate were decreased according to late application time. The content of inorganic nitrogen in soil showed high tendency at more application rate of MEC, and nitrogen mineralization at harvest season have finished in 50%, 70% plots of basal dressing. The content of inorganic nitrogen in soil was increased according to late application time, however it was decreased in the late period of growth. Leaf color value became darker with increased application rate of MEC. Leaf color was dark green in MEC application plots at panicle formation stage, on the other hand, it was light green in 50%, 70% plots of basal dressing at heading stage. SPAD reading value of leaf-color was high during the whole growth stage in MEC application plots. More application rate of MEC showed higher tendency of fertilizer nitrogen absorption. Nitrogen use efficiency was the highest in 70% plot of basal dressing. Absorbed amount of fertilized nitrogen was increased in 10~15days before transplanting and nitrogen use efficiency was high according to the late application time. The ratio of perfect kernel and the content of protein on hulled rice showed high tendency at the less application rate of MEC. The ratio of head rice on milled rice showed high tendency at the less application rate of MEC. Rice yield increased 4% in 100% and 70% plots of basal dressing compare with SFA (5.18 Mg ha-1) plot respectively. Ear and culm length of rice were long according to the late application time, while the numbers of spikelet and ear were increased and the percentage of ripened grain was decreased. Rice yield was increased 2~5% in all MEC application plots compared to SFA plot and especially, increased 10~15days before transplanting in application plots. The optimal application rate and time of MEC on normal paddy field in plain were concluded that 70% basal dressing and 10~15days before transplanting
