| 1 | Characterization of Nitrogen Uptake Pattern in Malaysian Rice MR219 at Different Growth Stages Using ^(15)N Isotope显示文摘Nitrogen(N) use efficiency is usually less than 50%, and it remains a major problem in rice cultivation. Controlled release fertilizer(CRF) technology is one of the well-known efforts to overcome this problem. The efficiency of CRF, however, is very much dependent on the timing of nutrient release. This study was conducted to determine the precise time of N uptake by rice as a guideline to develop efficient CRF. Fertilizer N uptake by rice at different growth stages was investigated by using 15 N isotopic technique. Rice was planted in pots, with 15 N urea as N source at the rate of 120 kg/hm2. Potassium and phosphorus were applied at the same rate of 50 kg/hm2. Standard agronomic practices were employed throughout the growing periods. Rice plants were harvested every two weeks until maturation at the 14 th week and analyzed for total N and 15 N content. Nitrogen derived from fertilizer was calculated. Total N uptake in plants consistently increased until the 11 th week. After that, it started to plateau and finally declined. Moreover, N utilization by rice plants peaked at 50%, which occurred during the 11 th week after transplanting. N derived from fertilizer in rice plants were in the range of 18.7% to 40.0% in all plant tissues. The remaining N was derived from soil. Based on this study, N release from CRF should complete by the 11 th week after planting to ensure the maximum fertilizer N uptake by rice plants. Efficient CRF should contribute to higher N derived from fertilizer which also resulted in a higher total N uptake by rice plants, increasing the potential of rice to produce higher yield while at the same time of reducing loss. | Mohammad Mu'az HASHIM Mohd Khanif YUSOP Radziah OTHMAN Samsuri Abdul WAHID | 2015 | Rice science2015，22，5： | 3 |

| 8 | A comparison of process performance during the anaerobic mono-and co-digestion of slaughterhouse waste through different operational modes显示文摘The use of consecutive feeding was applied to investigate the response of the microbial biomass to a second addition of substrates in terms of biodegradation using batch tests as a promising alternative to predict the behavior of the process. Anaerobic digestion(AD) of the slaughterhouse waste(SB) and its co-digestion with manure(M), various crops(VC), and municipal solid waste were evaluated. The results were then correlated to previous findings obtained by the authors for similar mixtures in batch and semi-continuous operation modes. AD of the SB failed showing total inhibition after a second feeding. Co-digestion of the SB + M showed a significant improvement for all of the response variables investigated after the second feeding, while co-digestion of the SB + VC resulted in a decline in all of these response variables. Similar patterns were previously detected, during both the batch and the semi-continuous modes. | Jhosané Pagés-Díaz Ileana Pereda-Reyes Jose Luis Sanz Magnus Lundin Mohammad J.Taherzadeh Ilona Sárvári Horváth | 2018 | Journal of Environmental Sciences2018，30，2： | 0 |
