Aims: Evaluate the effects of applying biostimulant and micronutrients on Acacia mangium Willd seedlings. Study Design: A randomized complete block design was used in a 2x5 factorial scheme, with four replications. Place and Duration of Study: The experiment was conducted at the Universidade Federal de Mato Grosso do Sul, at the Chapadão do Sul Campus, MS, with the geographical coordinates 18º46’ 44” S and 52º36’ 49” W, in a nursery area from October 2015 to January 2016. Methodology: The treatments consisted of a combination of the presence or absence of a solution containing micronutrients and five doses of biostimulant (0, 7.5, 15.0, 22.5, and 30.0 mL per L of water). The commercial product Stimulate™ was used as the biostimulant, and the micronutrient solution was prepared at the concentration of 1.0%. The micronutrients in the solution were in the following formulations: ZnS04, H3BO3 and CuS04. The seeds were sown in tubes containing the commercial substrate Carolina Soil do Brasil, together with the use of Osmocote Plus™ fertilizer. Results: The use of biostimulant associated with micronutrients favored the rate of emergency speed. The doses of 24.8, 14.0 and 26.1 mL L-1 of biostimulant water provided the highest values for leaf area, plant height and total dry mass, respectively, when associated with the use of micronutrients. The height / diameter ratio decreased with increasing doses of biostimulant, while the Dicson quality index increased in the same condition. Conclusion: The use of micronutrients and biostimulants were favourable for the production of A. mangium seedlings. Only the height/diameter ratio (HDR) reduced for all biostimulant doses.

The available lands are marginal such as Ultisols and Oxisols,where intensive bleaching occurs for the high rate of rainfall, and causesthe low content of magnesium in such land. There are three sources used toprovide the Mg nutrient, such as kieserite (Mg and S), dolomite (Ca andMg) and compound fertilizer. The objective of this experiment was tostudy the effect of kieserite fertilizer on plant growth and soil productivity.This research was conducted in the seedling plot of Cimulang Site, BogorDistrict (PTP. Nusantara VIII) in February- December 2005 on Ultisolsand Oxisols using a randomized complete block design with 5 treatmentsand 9 replicates. One oil palm seedling was planted in each treatment. Thisexperiment used kieserite powder 2 Panda to provide Mg and ordinaryKieserite as the standard. The kieserite dosages were 0, 0.5, 1.0, and 1.5g/plant. Fertilizing the plot was done every 2 weeks, using kieserite andbasic fertilizer or fertilizing 12 times, but the first fertilization was donewhen the plants reached 1 week of age. Starting on the second fertilization,the dosage was multiplied 2 times, and starting on the 10 th week, thedosage was multiplied 3 times, and starting on 18 th week the dosage offertilizing is multiplied 4 times. Bulk soil samples were air-dried, sievedpassing 2 mm siever, and put 20 kg into polybags. The research resultshowed that kieserite fertilization on Ultisols increased plant height,number of leaves, stems (leaf midrib) diameter, dry weight of biomass, Mgnutrient content in the soil (from 1.25 to 3.04 me/100 g), and alsoincreased the plant Mg content to become 0.31 g/100 g. In addition,kieserite fertilization on Oxisols increased plant height, number of leaves,stems (leaf midrib) diameter, plant dry weight of oil palm seedling, Mgnutrient content in the soil, (from 0.28 into 2.38 me/100 g), and increasedplant Mg content into 0.34 g/100 g. The optimum kieserite fertilizingdosage on Ultisols and Oxisols was just the same, i.e. 0.80 g/plant.

The research aims to investigate the effects of silica (Si) as an ameliorant on the proline compound concentration and the growth response of oil palm exposed to aluminum toxicity. The research was arranged in a complete randomized block design with 8 blocks as replications. The first factor was Al toxicity which consisted of two levels as without and with Al toxicity. Al toxicity treatment was applied by giving 300 ppm of Al concentrate along with watering activity regularly. The second factor was the application of silica which consisted of four levels as 0, 32, 64 g/plant. Proline and growth activities of leaf area, plant height, number of leaves, and dry weight were observed in the research. The data subjected to analysis of variance (ANOVA) at 5% test level. If the result of ANOVA showed significant differences among treatments, then the data would have been analyzed by Duncan’s Multiple Range Test (DMRT) at 5% test level. The results of the research provide information that Al toxicity increases proline compound in the plant tissues and decreases leaf area, plant height, number of leaves, and dry weight of Oil Palm. Applying Si at the level of 64 g/plant could increase proline concentrate and dry weight of oil palm exposed to A1 toxicity. Proline compound in the plant tissues did not have any correlation with the growth of oil palm. Thus, this case indicated that proline was a product and not a plant tolerant mechanism of Al toxicity.

Plant growth was evaluated between 90 and 390 days and production and growth were evaluated at 620 days after planting. There were significant interactions between spacing and fertilization for plant height, number of cladodes and cladode area index from 90 to 390 days and for production of fresh and dry matter at 620 days after planting. Spacing influenced cladode area index, while fertilization influenced plant height, number of cladodes and cladode area index at 620 days after planting. Plant height showed cubic effect for the days after planting. Number of cladodes and cladode area index were dependent on spacing, fertilization and plant age, and fitted to cubic models. The best results of growth and production of fresh and dry matter are associated with NPK and NP fertilizations and the spacing of 1.00 x 0.50 m.
