A field experiment using the split-plot design was conducted at two experimental sites, namely; Sioul and Busan, to investigate the effect of water management (mid-term drainage vs. continucus flood), time of fertilizer-N application (at transplanting vs. primordial initiation) and efficiency of fertilizer-N Carrier in paddy rice. In the study two high yielding rice varieties were used: Nongkwang, as a local variety and Bongkwang as an introduced variety. Water management was considered the main plot with the other effects: time of fertilizer-N application and efficiency of fertilizer as sub-plots. To determine the interactions labelled ?? ferilizers: urea and ammonium sulfate were used. The experimental design followed both at Seoul and Busan experiment site was in accordance with the IAEA guidelines. Individual plot size is 4×1.25m and each plot divided into three sub-plots by plastic sheet. Each sub-plot was labelled A,B, and C. Sub-plot A and B were for ?? fertilizer application while sub-plot C for non-labelled nitrogen fertilizer application. The area of sub-plot A is 1×1.25m sub-plot B, 0.75×1.25m; and sub-plot C, 2.25×1.25m. Plant density was 4 plants per hill planted in rows of 25×25cm. The various treatments were arranged in a split-plot design with two water managements as the main plot and the N-fertilization plus varieties as sub-plot. Each treatment replicated four times. Water was maintained continuously on the plot during the whole growing period. When 50% of the plants had reached the primordial initiation stage, nitrogen fertilizer was applied 2 days after the plots were fully drained, and immediately reflooded. Each plot was dizided into sub-plot A, B, and C with the plastic sheet. One sub-plot, either A or B, received ?? labelled fertilizer at transplanting and non-labelled N at primordial initiation. The other sub-plot received non labelled N at transplanting and ?? labelled fertilizer at primordial initiation stage. Sub-plot C received non-labelled fertilizer. The labelled fertilizer N were obtained from JUNTA DE ENERGIA NUCLEAR. Urea labelled on both nitrogen atoms was prepared by the reaction of ?? with diphenyl carbonate at high pressure under helium atomosphere. The product was purified by recrystallyzation from ethanol or acetone. Isotopic enrichment was 1.37%. Ammonium sulfate was produced by the reaction of ?? with sulfuric acid. Nursery management was done inaccordance with customary practices followed at each experimental site. Total amount of potassium chloride applied was 8kg/ha, potassium of which half was treated at transplanting time and primordial initiation stage respectively. As basal application 8kg/ha of phosphate was supplied in the form of superphosphate at both sites. A day before transplanting, fertilizers mixed with fine sand at 1 to 1 ratio were broadcast by hand. Watermanagement-water level in each plot was continuously maintained above 5cm from soil surface for the duration of the experiment except for mid-term drainage treatment. For the mid-term drainge treatment, the plots were drained for two days and reflooded immediately after the addition of the fertilizers. Appropriate agro-chemicals consisting of herbicide and insecticde were applied to control weeds and to protect the plants from insects and rice blast disease. Results of the various interactions were evaluated in terms of A-value and ERA. Water management, continuous flooding vs. mid-term drainage have no significant effect on A-value. However, significant differences were observed in time of fertilizer-N application and in fertilizer-N Carrier. On time of fertilizer-N application A-value were increased at transplanting time as compared to that primordial initiation. Results indicate that young rice seedling utilizes more soil nitrogen than at later stages of development. On fertilizer-N Carrier, ammonium sulfate was observed to be a better source of nitrogen than ruea. Significant difference was also observed between the two varieties used in this study. Bongkwang contained higher nitrogen percentage in grain than Nongkwang regardless of experimental sites. When ammonium sulfate was applied, %NDFF was increased regardless of varieties at Seoul site where-in A-value is less that of Busan. As far as timing of application, nitrogen fertilizer applied at primordial initiation was more favorable than at transplanting regardless of varieties and fertilizer-N Carrier and the results abbreviated were as follows: 1. Protein contents in hulled grain were increased by applying ammo-sulfate as compared with urea. 2. Protein contents in hulled grain were increased by top dressing of ammo-sulfate. 3. The more protein in straw, the more protein in hulled grain. 4. Protein amounts in hulled grain were increased in accordance with the nitrogen(??) amounts applied. 5. No obvious difference was appeared between the treatment of mid-term drainage and control in terms of plant height and number of tillers; but the later growth on plant height was accelerated in the plots of mid-term drainage as compared with the plots, control; while the number of tiller per-hill was decreased at the later growing season. 6. Statistically high significance in Nongdwang variety was appeared almost all the items of yield components, interaction among mid-term drainage, fertilizer application and variety was shown in terms of maturing rate, seed-bearing rate and weight of 1,000 kernels. No statistical significance except the length of ears was found in mid-term drainage treatment in each terms of yield components, and the values observed were increased, and the application effect of urea and ammonium sulfate in the factor of fertilizer application was not revealed. 7. Statistically significant difference between the treatments of mid-term drainage and fertilizer applied was not shown on % of total nitrogen of rough grain, hulled grain was revealed in factor of variety. 8. Contents of nitrogen applied in rice plant(nitrogen fertilizer traced with 15N Isototpe) at transplanting was assumed approximately 3∼4% as compared with total nitrogen in rice plant and 10% was contained by top dressing applied at primordial initieation stage 9. At the time of fertilizer-N application, regardless of fertilizer N carrier, A-value at transplanting time was higher than that at primordial initiation. 10. A-value of ammonium sulfate applied at transplanting time, both grain and straw was higher as compared with urea. 11. Nitrogen application at primordial initiation stage significantly increased an effective rate of application (E. R. A) as compared with the stage of transplanting both in grain and straw. 12. E. R. A. measurements in the treatment of ammonium sulfate increased as compared with urea. 13. Increasing trend was appeared in the weights of hulled grain, as the effective rate of application at transplanting is lower, and A-value at that time is bigger. 14. The ratio of A-value to soil total nitrogen ranges from 9.9% to 41.8% in grain and 6.7% to 35.6% in straw.

A field experiment using the split-plot design was conducted at two experimental sites, namely; Seoul and Pusan, to investigate the effect of water management (mid-term drainage vs. continuous flood), time of fertilizer-N application (at transplanting vs. primodial initiation) and efficiency of fertilizer-N carrier in paddy rice. In the study two high yielding rice varieties were used: Nongkwang, as a local variety and Bongkwang as an introduced variety. Water management was considered the main plot with the other effects:time of fertilizer-N application and efficiency of fertilizer as sub-plots. To determine the interactions labelled N-15 fertilizers: urea and ammonium sulfate were used. The experimental design followed both a Seoul and Pusan experiment sites was in accordance with IAEA guidelines. Individual Plot size is 4×1.25m and each plot divided into thrce sub-plots by plastic sheet. Each sub-plot was labelled A, B, and C. Sub-plot A and B were for N-15 fertilizer application while sub-plot C for non-labelled nitrogen fertilizer application. The area of sub-plot A is 1×1.25m sub-plot B, 0.75×1.25m; and subplot C, 2.25×1.25m. Plant density was 4 plants per hill planted in rows of 25×25㎝. The various treatment were arranged in a split-plot design with two water managements as the main plot and the N-fertilization plus varieties as subplot. Each treatment replicated four times. Water was maintained continuously on the plot during the whole growing period. When 50% of the plants had reached the primordial initiation stage nitrogen fertilizer was applied 2 days after the plots were fully drained, and immediately reflooded. Each plot was divided into sub-plot A, B, and C with the plastic sheet. One sub-plot, either A or B, received N-15 labelled fertilizer at transplanting and non-labelled N at primordial initiation. The other sub-plot received non labelled N at transplanting and N-15 labelled fertilizer at primordial initiation stage. Sub-plot C received non labelled fertilizer. The labelled fertilizer-N were obtained from JUNTA DE ENERGIA NUCLEAR. Urea labelled on both nitrogen atome was prepared by the reaction of ?? with diphenyl carbonate at high pressure under helium atmosphere. The product was purified by recrystallyzation from ethanol or acetone. Isotopic enrichment was 1.37%. Ammonium sulfate was producted by the reaction of ?? with sulfuric acid. Nursery management was done in accordance with customary practices followed at each experimental site. Total amount of potassium chloride applied was 8㎏/ha, potassium of which half was treated at transplanting time and primordial initiation stage respectively. As basal application 8㎏/ha of phosphate was supplied in the form of super-phosphate at both sites. A day before transplanting, fertilizers mixed with fine sand at 1 to 1 ratio were broadcast by hand. Watermanagement-Water level in each plot was continuously maintained above 5cm from soil surface for the duration of the experiment except for mid-term drained treatment. For the mid-term drainage treatment, the plots were drained for two days and reflooded immediately after the addition of the fertilizers. Appropriate agro-chemicals consisting of weedicide and insecticide were applied to control weeds and to protect the plants from insects and rice blast disease. Resulted of the various interactions were evaluated in terms of A-value and ERA. Water management, continuous flooding vs. mid-term drainage have no significant effect on A-value. However, significant differences were observed in time of fertilizer-N application and in fertilizer-N carrier. On time of fertilizer-N application A-value were increased at transplanting time as compared to that at primordial initiation. Results indicate that young rice seedling utilizes more soil nitrogen than at later states of development. On fertilizer-N carrier, ammonium sulfate was observed to be a better source of nitrogen than urea. Significant varietal difference was also observed between the two varieties used in this study. Bongkwang contained higher nitrogen percentage in grain than Nongkwang regardless of experimental sites. When ammonium sulfate was applied, % NDFF was increased regardless of varieties at Seoul site where-in A-value is less than that of Pusan. As far as timing of application, nitrogen fertilizer applied at primordial initiation was more favorable than at transplanting regardless of varieties and fertilizer-N carrier, and the results abbreviated were as follows; 1. Protein contents in hulled grain were increased by applying ammo-sulfate as compared with urea. 2. Protein contents in hulled grain were increased by top dressing of ammosulfate. 3. The more protein in straw, the more protein in hulled grain. 4. Protein amounts in hulled grain were increased in accordance with the nitrogen (??) amounts applied. 5. No obvious difference was appeared between the treatment of mid-term drainage and control in terms of plant height and number of tillers; but the later growth on plant height was accerelated in the plots of mid-term drainage as compared with the plots, control; while the number of tiller per-hill was decreased at the later growing season. 6. Statistically high significance in Nongkwang variety was appeared almost all the items of yield components, interaction among mid-term drainage fertilizer application and variety was shown in terms of maturing rate, seed-bearing rate and weight of 1,000 kernels. No statistical significance expect the length of ears was found in mid-term drainage treatment in each terms of yield components, and the values observed were increased, and the application effect of urea and Ammonium sulfate in the factor of fertilizer application was not revealed. 7. Statistically significant difference between the treatments of mid-term drainage and fertilizer applied was not shown in % of total nitrogen of rough grain, hulled grain was revealed in factor of variety. 8. Contents of nitrogen applied in rice plant (nitrogen fertilizer traced with ?? Isotope) at transplanting was assumed approximately 3-4% as compared with nitrogen, and 10% was contained by top dressing applied at primordial stage. 9. At the time of fertilizer-N application, regardless of Fertilizer-N carrier, A-value at transplanting time was higher than that at primordial initiation. 10. A-value of ammonium sulfate applied at transplanting time, both grain and straw was higher as compared with urea. 11. Nitrogen application at primordial initiation stage significantly increased an effective rate of application (E.R.A) as compared with the stage of transplanting both in grain and straw. 12. E.R.A. measurement in the treatment of ammonium sulfate increased as compared with urea. 13. Increasing trend appeared in the weights of hulled grain, as the effective rate of application is lower, and A-value is bigger. 14. The ratio of A-value to soil total nitrogen ranges from 9.9% to 41.8% in grain and 6.7% to 35.6% in straw.

These Experiments were conducted to study the effect of single and combined application of composts and slaked lime in a sandy loam paddy field. In the latter experiment the combination of both materials were performed two ways, mixing together for two months prior to the placement and using together just at the time of application respectively. A variety of rice, "Nongrim#6" was enployed as the subject crop. The yield components were examined on the 11 tretments, as well as the effect of each treatment and the relationship among them in determining main components of the plants sampled on heading date. The results were as follows; 1. The single application of composts and lime, as compared with that without composts and lime, showed the increasing tendency in terms of culm and ear length, and the number of panicles and average spikelets per ear were decreased. The former had higher yield. In most yield components except the ratio of efficient ear, both applications of composts and lime gave the increasing yield. 2. The increasing amount of lime in the case of single use, increased the number of ear and spikelets per ear; while mautring fate and 1,000 grain weight tended to decrease slightly but yields were higher than the plat, control. 3. In the case of lime application with composts, were remarkably increased both the number of ear and spikelets per ear maturing ration, but the difference in 1,000 grain weight was not showed, The yields were highly increased, In applying both composts and lime, the methodic difference showed a slight variation in yield components of rice. 4. Even a single application of lime made increment in the contents of nitrogen, phosphorus, lime and silica, of plants, on the contrary the content of potassium was decreased rather rhan increasing. In this experiment the more lime was used, the lower was the content of potassium, The single application of composts brought a higher content of each element as compared with the case without compost, and the combined application of composts and lime increased contents of all the elements not only in the plot, control, but in the plots singly applied with composts or lime, When both composts and lime were placed, the content of each component in plants did not show difference in accordance with the treatments. 5. The amount[Dry matter weight x density(%)] of each component of the plant per unit area showed the result of identical tendency to the content of the content of the plant. 6. The relationship of yield components contents of nitrogen, phosphorus, potassium, lime and silica of plants on heading date, and the amount per unit area are as follows: (1) correlation of the number of average spiklelets per ear and the content of each element is over Υ=0.777, and all showed highly significant correlation: particulray the nitrogen content showed the highest correlation as of Υ=0.938. The correlation of the total amount of each component also as of Υ=0.802 showed the identical tendency to the nitrogen content in plants. (2) In the relationship between maturing rate and each component, potassum was the only one displaying the highest degree of significant correlation, On the other hand nitrogen, phosphorus, lime and silica showed an average degree of correlation In the amount of each component per unit area potassium showed highly significant correlation, and nitrogen and phosphorus showed an average one. Lime and silica did not yield the statstical significance. (3) Among 1,000 grain weight and content of each component aed the total amount per unit area was not showed any significant correlation. (4) The correlation between grain yield and the content of each component was over Υ=0.759, and that among the total amouts of the compontents was more than Υ=0.770, All of them showed statistically the highly significant correlation. 7. The ratio of nitrogen, phosphorus and potassiun to the content of main components of plants were as follows; (1) The ratio of mitrogen to other components namely ??, K₂O/N, CaO/N, SiO₂/N in compariison with the control, shoed showed an inreasing trend both in the single and combined application of lime and composts, and the varied treatments of combined application also showed the similar tendency. (2) The ratio of phosphorus to other components, ??, ??, ?? and ?? showed decreasing tendency in both the single and combined applications of lime and composts, The treating methods of combined application rarely showed the difference. (3) The ratio of potassium to other components N/K₂o, ??, CaO/K₂O and SiO₂/K₂O whether in the single or combined application of composts and lime was increased, However, there was no significant difference among the treatments.
