Abstract Medicinal plants often used is pegagan (Centella asiatica). Due to the benefits of pegagan, it is important to know the growth of this plant in detail, in this case, the growth of tendrils, which is, of course, related to biomass production. Plant materials are needed that are guaranteed production levels and quality by applying recommended cultivation. This study was proposed to understand the influence of phosphorus on the growth of pegagan tendrils. This research was conducted using a single factor with six levels of P2O5 fertilizer dosage with a non-factorial randomized block design repeated 3 times. The 6 levels of fertilizer dosage are 0, 20, 40, 60, 80, 100 kg P2O5/ha. The treatment of phosphorus (F) at 3-12 WAP did not reveal a prominent influence on the number of the primary tendrils; however, phosphorus's application affects the growth component of the primary tendril length in acid soil conditions. Pegagan can still grow well even though the land conditions are very acidic.

<p>The experiment was conducted to determine the effect of phosphorous fertilization on growth and production of Indian pennyworth (Centella asiatica L. Urban) in the high altitude (1,500 m above sea level/asl). This experiment was carried out at Gunung Putri experimental station Balittro,Cipanas, Cianjur in October 2008 until April 2009. The treatment was laid-out in a Complete Randomized Block Design and consisted of single factor with 5 replications. The factor was P2O5 fertilization i.e. 0, 30, 60, 90, and 120 kg P2O5.ha-1. The results of the experiment showed that P2O5 fertilizer significantly increased the total leaf number, leaf length, the total flower number, leaf thickness of mother plant and production components at 6 month after planting. The highest production (1.34 ton dry weight.ha-1) was achieved by 60 kg P2O5.ha-1. The optimum dosage to improve dry weight production of Indian pennyworth in high altitude was 65.84 kg P2O5.ha-1.</p><p><br />Key words: Centella asiatica L., phosphorous fertilization, production</p>

AbstractPhosphorus availability is the major constraint for plant growth in the acid soil ecosystem, due to high fixation by Al and Fe. Microbial fertilizers such as phosphate-solubilizing bacteria (PSB) can increase P availability in soils for root uptake. The objective of the research was to verify the ability of four isolates of PSB isolated from acid soil to solubilize unavailable inorganic phosphate, produce phosphatase, malic acid and indole acetic acid (IAA), as well as increase plant height of maize seedling. The bioassay by growing maize seedling in liquid nutrients has been performed to study the response of seedling to PSB inoculation. The experimental design of bioassay was a randomized block design with five replications. The results showed that the isolates RR 1 and SPR 4 had a relatively high solubilizing index. Moreover, all the PSB isolates had the ability to produce phosphatase and IAA and dissolve P. The performance of PSB-inoculated seedling was better visually and the root length was increased by 66.7–74.5% compared to the control. This result concludes that the species of four isolates needs to be identified by a biomolecular method and formulated as biofertilizers for increasing the maize productivity in the acid soil ecosystem.

Set Up

Papaya is a popular fruit and is grown commercially in many subtropical and tropical countries. Papayas are generally grown from seeds; therefore the offsprings are not true-to-type and could come in three sexes, female, male, and hermaphrodite. Clonal propagation is required to obtain to grow true-to-type hermaphrodite papayas. In this research, we developed an in vitro protocol for shoot multiplication from lateral shoots from in vitro germinated papaya seedlings. The in vitro propagated plant materials could potentially be used as a source of papaya micro cuttings, or as scion for papaya grafting. The experiment was set up as a factorial experiment with NAA at 0, 0.1 and 0.5 mg.L-1, and BAP at 0, 0.1, 0.5, and 1.0 mg.L-1 in a completely randomized block design. BAP interacted with NAA in affecting the shoot production per explant. The optimum BAP and NAA concentration to produce lateral shoots was 0.54 mg. L-1 and 0.1 mg.L-1, respectively. Media without NAA reduced the number of lateral shoots and number of leaf per explant at any BAP concentration.Keywords: hermaphrodite, seeds, true to type, clonal propagation, micro cuttings.

Efforts to increase production potential can be carried out by extensification in a less productive saline land. Salinity is a major problem in the growth of most plants. Azolla is a plant that is sensitive to salinity, but if it is applied well, it can grow optimally at high salinity levels. The purpose of this study is to obtain an azolla application technique that is effective in increasing the adaptation of rice plants to NaCl saline soil conditions. The experimental design used was Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor was the azolla application technique consisted of 3 levels: fresh azolla composted, fresh azolla immersed, and fresh azolla as a ground cover. The second factor was the levels of NaCl salt stress consisted of 4 levels: control DHL 0, 2, 4, and 8 dS m-1. The adaptation ability of rice plants based on variable plants height growth rate, number of tillers, strove dry weight, root dry weight, stomata density, leaf chlorophyll (SPAD), age of flowering, number of paddy grain, and harvest index. The results showed how to test content up to 2 dS m-1 which increased rice growth especially the application of azolla composted. Increasing stress to 4 and 8 dS m-1showed bad effects on vegetative, physiology, and yields of rice components. The stronger of salt stress the higher all plants growth variables except the age of flowering that actually showed the acceleration of flowering. Application of composted azolla can increase the root dry weight and azolla as a ground cover can increase the numbers of paddy grains.   Keywords: azolla, NaCl, rice, stress

The aim of the study is the effect of nitrous oxide (N2O) emissions on rice field. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Sriwijaya University, Indralaya Campus. The N2O gas analysis was conducted at the Laboratory of the Indonesian Agricultural Environment Research Institute, Ministry of Agriculture, Central Java. From April to July 2016. This study used a Randomized Block Design (RBD) with irrigation classes, namely 5 cm (A1), intermittent / intermittent (A2) plots, and saturated land (A3), divided into three (3) groups with a total of 18 treatments, so that there were 54 plots in total. Observation of N2O gas was chosen at weeks 2, 4, 6 and 8 after planting using a closed lid for 24 hours. N2O gas flux is calculated based on an equation adopted from the International Atomic Energy Agency (IAEA). The results obtained are the emission of N2O gas produced by maps with air saturation condition of 5 cm from the surface of the land (A3) in the amount of 1564,554 mg N2O / ha / day and the lowest is produced by inundated plots (A1) with a value of 648,996 mg N2O / ha / day. Soil conditions that are inundated during plant growth produce anaerobic soil conditions capable of lifting N2O flux compared to air-saturated conditions.

The productivity of potatoes in Indonesia is relatively low and unstable caused by unsuitable enviromental and soil conditions and bad cultivation system. This research was conducted to study the effect of NPK fertilizer dosages and soil order to soluble K, K Uptake, and yield of seed potatoes (Solanum tuberosum L.). The experiment design used a factorial randomized block design with two factors and three replication. The first factor was NPK fertilizer dosages with five levels (0, 25, 50, 75, 100% recomendation dosages) and the second factor was soil orders with two levels (Andisols and Inceptisols). The results of experiment showed that the interaction effect between NPK fertilizer dosages and soil orders had significantly effect to soluble K and K Uptake. There were independent effect of NPK dosages to diameter of potatoes tuber and independent effect of soils order to yield of seed potatoes. Andisols with 25% NPK and Inceptisols with 50% NPK were the best combination treatment to increase soluble K while treatment Inceptisols with 25% NPK was the best combination treatment to increase K Uptake. Dosages of 25% NPK was the best treatment to increase diameter of potatoes tuber while Inceptisols was the best treatment to increase yield of seed potatoes.Keywords : NPK Fertilizer Dosages, Andisols, Inceptisols, Potassium, Potatoes
