Limestone mining activities are damaging soil and enviroment. Revegetation becomes an obligation on every mining sites. Paraserianthes falcataria is one of many species that suitable to be planted in revegetation site. Adding compost and NPK fertilizer can improve soil’s condition. This research objective is to analyze the effect of compost and NPK fertilizer on Paraserianthes falcataria seedlings growth and the exact appropriate dosage for limestone mining’s soil condition improvement. The design used in this research is completely randomized design with two factors. The result shows that addtion of compost on tailing media doesn’t give major effect or statistically not significant on seedling growth of height, diameter, the amount of root nodules, and shoot-root ratio, but statistically significant on wet and dry weight of the seedlings. NPK fertilizer addition on tailing media is statistically significant on the seedling growth of diameter, wet weight, and shoot-root ratio, but not significant different on height, dry weight, and the amount of root nodules. Interaction between compost and NPK fertilizer on media gives effect only at 95% of confidence level. K1N5 sample (with 100 gram composts and 5 gram of NPK fertilizer) gives the best respond on seedling’s growth. Very high levels of Ca in the soil medium will be toxic to the Paraserianthes Falcataria plant.Keywords: Compost, limestone mining, NPK fertilizer, Paraserianthes falcataria

ABSTRACT In order to investigate salinity stress on seed reserve utilization and seedling growth of treated seeds of barley (Hordeum vulgare L.), an experiment was carried out. Factorial experiment was carried out in completely randomized design with three replicates. To create salinity stress, NaCl in osmotic levels at 0 (as control), -4, -8, -12 and -16 bar were used. For seed priming, gibberellin (GA) 50 ppm was used. Our results showed that treatment × drought interaction on these traits: germination percentage, weight of utilized (mobilized) seed, seed reserve utilization efficiency, seedling dry weight and seed reserve depletion percentage were significant. The highest germination percentage, weight of utilized (mobilized) seed, seed reserve utilization efficiency, seedling dry weight and seed reserve depletion percentage were attained from priming by gibberellin at control conditions. Thus, priming increased characteristics as compared to the unprimed. Priming improved seed reserve utilization such as: weight of utilized (mobilized) seed reserve, seed reserve depletion percentage, seed reserve utilization efficiency and seedling growth in barley under salinity stress.

Suitable clover stands (field and meadow) were chosen to isolate new R. leguminosarum bv. trifolii strains. Together 49 strains were isolated, labelled and maintained. Ten primers were used for identification and amplification products were detected by agarose electrophoresis. Amplification products of individual primers did not make possible to distinguish all isolates; a combination of at least two primers was necessary. No differences in genetic variability level between field and meadow isolates were found. Hydroponic perlite experiments were used for the screening of rhizobial isolates and the tetraploid red clover variety Amos was used as a host plant. Shoots were weighed and the root volume was determined at the onset of anthesis. Total nitrogenase activity (TNA) of the symbiotic system was measured and the root dry weight was determined. High differences among individual isolates were found in all the characteristics. Statistically significant were differences among individual isolates for TNA, growth characteristics did not differ significantly. Strong positive relationships between fresh forage, dry forage, root volume and root dry weight were determined (r = 0.69–0.98; p > 0.05). Nine isolates were selected as effective, based on the mean values of all isolates screened. Selected isolates achieved the above average values in most measured characteristics. Out of the nine isolates, two were isolated from root nodules of clover cultivated in field stands, seven strains were isolated from clover grown in natural meadows. Additional study of isolates in soil condition will follow.

The objective of the present study was to examine the growth responses of Acacia mangium (mangium) and Paraserianthes falcataria (sengon) seedlings growing on different soil origin under nursery condition. This study was started in September 2012 and terminated in March 2013.  The seedlings were grown from seeds sown in a plastic box filled with sterilized sands. One week after sowing, the seedlings were transplanted into polybags contained sterilized soils originated from secondary forest, Imperata cylindrica grassland and ex-coal mining. The number of all seedlings were 180 seedlings consisted of 3 different soils, 2 species of seedlings with 10 seedlings replicated 3 times. Assessment was conducted one week after transplanting, then subsequently monitored every 2 weeks, except dry weighing and counting nodules were performed at the end of the study. A completely randomized design was used in this study. The data was analyzed using Costat software. The study resulted that the different of soil origin influenced on all growth variables of mangium and sengon of 4.5 months old. The survival rate of seedlings, height and diameter increments, dry weight and root nodules were better in both species of seedlings growing on soil originated from secondary forest and Imperata grassland compared with the soil from ex-coal mining. But the survival rates of sengon seedlings were higher than that of mangium on these three soils. The highest dry weight of sengon seedlings was achieved on soil originated from secondary forest. In the present study, soil originated from secondary forest increased more in weight of shoot than root, so that the shoot-root ratio was unbalanced more than one. Based on the results of this study, it is recommended that soil from secondary forest and Imperata grassland can be used as growing media for mangium and sengon seedlings in the nursery.

 The objective of this study was to determine the response of oil palm seedling to the application of arbuscular mycorrhiza fungi (AMF) subjected to water stress.  The treatment design used was a factorial design 2 x 5 arranged in completely randomized design.  The first factor was application of AMF i.e. without AMF (control) and inoculation with AMF (mixture of Glomus sp., Entropospora sp., and Gigaspora sp.).  The second factor was water stress i.e. no watering for 0, 7, 14, 21, and 28 days at the end of experiment.  Data obtained were subjected to Bartlett test to examine the treatment variance, and Tukey tests to examine additiveness of the data, and continued by analysis of variance. The results showed that application of AMF increased oil palm seedling growth through the increase in seedling height, number of leave, shoot fresh and dry weight, and percent of root infection.  Duration of water stress significantly affected oil palm seedling growth by decreasing plant height, number of leave, shot and root fresh weight, root dry weight. However, at any level of water stress, the AMF inoculated seedling had better growth compared to those control palms.[Key words: oil palm seedling, arbuscular mycorrhiza fungi (AMF), water stress] AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh pemberian fungi mikoriza arbuskular (FMA) terhadap respons pertumbuhan bibit kelapa sawit yang mengalami cekaman air.
