This study was carried out to determine the effects on rice growth, yields and soil improvement under the different nitrogen levels in machine-transplanted rice after plowing at the fruiting stage of milk vetch. The fresh weight of milk vetch at plowing time was 20.95 ton/ha. In dry weight, T-N and C/N were 1.58%, 21.8%, respectively. Organic matter, total nitrogen and exchangeable calcium of soil after the experiment in the plot of milk vetch were higher than those before the experiment. Leaf area and dry weight of rice plants at heading date increased as nitrogen level increased. The number of panicle and spikelets per ~textrmm2 were not different except for the 110 kg/ha nitrogen level plot with milk vetch. Brown rice yield ranged from 5.45 to 6.08 ton/ha, in creasing with increased nitrogen level. So the yield increased by 1% at 77 kg/ha nitrogen level, 7% at 110 kg/ha nitrogen level plot with milk vetch compared with conventional level (rice straw 5.4 ton/ha and nitrogen 110 kg/ha).

밭에서 수도 품종을 재배할 때 적정 파종방법 및 재식밀도를 구명하고자 전라남도 무안군 현경면 평산리 농가포장에서 실시하였다. 시험품종은 수도품종인 상주찰벼와 화영벼를 사용하였고, 파종방법은 인력점파, 기계점파, 조파, 산파 등이었고 파종방법별 재식거리는 조파의 경우 30×5, 25×5, 20×5㎝등 3조건, 인력점파의 경우 40×12, 40×24, 20×12, 20×24㎝등 4조건으로 파종하였다. 1. 파종방법별 입모수는 파종시기에 관계없이 산파가 가장 많았다. 2. ㎡당 수수는 4월 20일 파종이 5월 20일 파종보다 약간 많았고 과종방법 중에는 가장 산파가 많았다. 수당입수는 파종시기에 관계없이 차이가 거의 없었으나 파봉방법 중에서는 산파가 가장 적었다. 등숙율은 상주찰벼가 70.3~72.9%이고 화영벼는 75.6~77-8%로 현저히 낮았다. 3. Ha당 쌀 수량은 상주찰벼의 경우 파종방법간 유의적인 차이가 없었으나 화영벼의 경우 파종시기에 관계없이 인력점파와 조파가 기계점파와 산파 보다 높았다. 4. 수도 기계이앙 재배의 가능성을 알아보기 위해서 시험한 결과, 어린모가 중묘 보다 모 도복 및 결주율이 낮고 활착이 빨리 이루어져 포기생육이 좋았다. 수량은 중묘와 차이가 거의 없었다. 5. 입모수는 파종방법에 관계없이 재식밀도가 작을수록 약간 많았다. 상주찰벼를 20×5㎝로 처리한 구만 제외하고 모든 처리 구에서 ㎡당 입모수가 100개 이상이었다. 6. ㎡당 수수는 재식밀도가 클수록 많았으나 수당입수, 등숙비율 및 현미천립중은 ㎡당 수수와 반대의 경향이었다. 10a당 수량은 조파의 경우 상주찰벼에서 재식거리 30×5㎝가 다 른 처리 보다 많았고, 인력점파의 경우 재식거리 40×24㎝를 제외하고는 처리간 유의적인 차이가 없었다. This study was carried out to investigate a proper seeding method and planting density for paddy rice cultivated on upland soil. Four seeding methods such as hand-hill seeding, machine-hill seeding, drill seeding, and broadcast seeding were used. The planting density consisted of three levels(30×5, 25×5, 20×5㎝) in drill seeding and four levels(40×12, 40×24, 20×12, 20×24㎝) in hand-hill seeding. Of the four seeding methods, broadcast seeding had the highest seedling stand per ㎡ regardless of seeding times. The panicle number per ㎡ in the April 20 seeding higher than that at the May 20 seeding. The percent ripened grain was 70.3~72.9% in Sangjuchalbyeo and 75.6~77.8% in Hwayeongbyeo. Yield of 10a in Sangjuchalbyeo was not significantly different by seeding methods but yield of hand-hill seeding and drill seeding was higher than that of machine-hill seeding and broadcast seeding in Hwayeongbyeo. Also, this field experiment was conducted to find out the feasibility in machine transplanting on upland soil. Seedling lodging degree and missing hill of 10-day old seedling was lower than that of 30-day old seedling. Yield per l0a was no difference between 10-day old seedling and 30-day old seedling. The number of seedling stand was a little increased as planting density decreased regardless of seeding method. The number of seedling stand per ㎡ was above 100 in all treatment plot except for the 20×5㎝ planting density in Sangjuchalbyeo. The panicle number per ㎡ was increased as planting density increased but grain number per panicle, percent ripened grain and 1,000 grain weight in brown rice was reverse tendency as panicle number per ㎡. In drill seeding, yield of l0a in 30×5㎝ planting density was higher than that in others in Sangjuchalbyeo. Yield of all treatments were not significantly different except for the 40×24㎝ planting density in hand-hill seeding.
