Java Ginseng (Talinum paniculatum Gaertn.) is a succulent plant from the family Portulacaceae which can be consumed as vegetable. There were three main objectives for the research. Firstly, to evaluate the growth of plants Talinum paniculatum (Jacq.) with the different levels of nitrogen and harvesting times. Secondly, to understand the level of nitrogen fertilizer on the largest biomass production. Thirdly, to know the harvesting weeks for the largest biomass production with the best quality. The combination treatment between the harvesting times of 8 wk and the manure 150 kg N ha -1 has effects on the plant height, the numbers of branches and leaves. The highest protein content was reached at 4 wks harvesting age with fertilization of 150 kg N ha -1 with significant difference in all treatments.

<p>Organic fertilizer expected increase number of growth and yield of pak choy. This research aims to study the influence of solid organic fertilizer and liquid organic fertilizer on growth, physiological characters, and yield of pak choy. The method used was Randomized Complete Design and three replications. The parameters observed were number of leaves, leaf area, chlorophyll content, Nitrate Reductase (NR), yield and harvest index. The result showed that the highest leaf number with 13.3 leaves was achieved by combination of SOF 20 t.ha^-1 and LOF 3 times a week.  The largest leaf area was 208.44 cm²due to the application of Solid Organic Fertilizer 20 t.ha^-1.The largest chlorophyll content was 0.84 mg.g-1 due to the combination treatment of SOF 20 t.ha^-1 and LOF 3 times a week.  The largest NR of Pak choy is 3.51 µ mol NO2.hr^-1 due to the combination treatment of SOF 20 t.ha ^-1 and LOF 3 times a week. The highest yields of pak choy is 29.79 kg.plot^-1 is due to combination treatment SOF of 20 t.ha ^-1 and LOF 3 times a week, the highest harvest index was 94.6% due to combination treatment of SOF 20 t.ha ^-1 and LOF 3 times a week.</p>
