ABSTRACT Rice as a staple food for most of Indonesia's population,their needs increase with increasing population, conversely production decreases. One effort to meet the needs of rice is by planting upland rice in dry land. Ultisol is the most extensive dry land in Indonesia. The yield of upland rice in Ultisol is very low, this is caused by various problems including acid reaction, high Al saturation and P fixation, availability of macro nutrients (N, P, K, Ca, Mg), low micro nutrients (Mo). Rice husk ash and natural phosphate can be used to increase pH and nutrient availability. The purpose of study was to study the effect of the interaction of rice husk ash and natural phosphate in increasing the growth and yield of upland rice ( Oryza sativa L.) on Ultisol medium. The study was conducted at the Faculty of Agriculture greenhouse, University of Riau from March to July 2019. The research was an experiment in the form of a 4x3 factorial using a completely randomized design. The first factor consists of four levels of rice husk ash (0.0; 1.5; 3.0; and 4.5 tons ha -1 ), the second factor of natural phosphate consists of 3 levels (0, 25 and 40 kg P 2 O 5 ha -1 ), each repeated three times. The results showed the interaction between rice husk ash with a dose of 1.5 tons ha -1 and natural phosphate with a dose of 25 kg P 2 O 5 ha -1 increased plant height, number of productive tillers, panicle length, number of paddy grains with pan, paddy grains and dry grain weight milled compared without rice husk ash and natural phosphate, each of these parameters tends to increase higher at the highest dose (4.5 tons ha -1 rice husk ash and 40 kg P 2 O 5 ha -1 natural phosphate).
大米作为印尼大多数人口的主食，其需求量随着人口的增加而增加，反之产量则减少。满足水稻需求的一项措施是在旱地种植旱稻。Ultisol是印尼最广阔的旱地。旱稻在Ultisol中的产量很低，这是由酸反应、高铝饱和度和高固磷、宏量养分(N、P、K、Ca、Mg)有效性和低微量养分(Mo)等各种问题造成的。稻壳灰和天然磷酸盐可用于提高pH值和养分有效性。研究稻壳灰与天然磷酸盐在Ultisol培养基上互作对旱稻生长和产量的促进作用。该研究于2019年3月至7月在廖内大学农业温室学院进行。该研究是一个4x3阶乘的实验，采用完全随机设计。第一个因子包括4个水平的稻壳灰分(0.0;1.5;3.0;和4.5吨公顷-1)，天然磷酸盐的第二个因素包括3个水平(0,25和40公斤p2o - 5公顷-1)，每个重复三次。结果显示之间的交互稻壳灰剂量的1.5吨公顷1磷酸和自然的剂量25公斤P 2 O 5公顷1增加株高、有效分蘖数、穗长、水稻谷粒的锅,稻田谷物和干粒重磨没有稻壳灰和天然磷酸盐相比,这些参数会增加更高的最高剂量(4.5吨公顷1稻壳灰和40公斤P 2 O 5公顷1自然磷酸盐)。

The main problems of rice cultivation in Ultisol medium are acid reactions, Al saturation and height P fixation, as well as low availability macro, micro nutrients especially Mo and Si. Rice plants need silicate in large quantities even though it is not an essential nutrient, therefore husk ash can be used as a source of Si. P availability increased by applying P fertilizer which was classified as slow realease so that fixation can be supported. The research aims to study the interaction of rice husk and rock phosphate is able to improve Si and P uptake and the growth of upland rice growth on Ultisol medium. The research was conducted at the Green House of the Faculty of Agriculture, University of Riau, Pekanbaru from January to March 2019. The research in form factorial experiment 4×3 was arranged in a completely randomized design, 3 replications. The first factor was rice husk consist of 4 levels (0, 1,5, 3, and 4,5 ton ha). The second factor was rock phosphate consist of 3 levels (0, 25, 40 kg P2O5 ha . The results showed the application of rice husk dose of 3 ton.ha and rock phosphate dose of 25 kg P2O5 ha increased Si and P uptake, P uptake efficiency, the root volume, dry weight, root canopy ratio, and plant growth rate.

ABSTRACT The toxicity of Al, Fe, and Mn is highly determined by the shape of the metal fractions. Therefore, the specific forms of Al, Fe, and Mn inside the soil are very important to know because they are related to soil fertility. The purpose of this study was to determine the distribution of the Al fraction on the acid soil profile of dry land in Lebak Regency, Banten Province. This research was conducted from April to June 2019 in Maja District, Lebak Regency, Banten. The research was descriptive explorative with intentional sampling for special purposive sampling. The soil was tested with a main parameter using single extraction for Al Fractionation. The results showed that the Al fraction in amorphous form (Al-o) was more dominant than Al in dissolved form (Al-dd) in all horizon layers (0-120 cm). Moreover, the Al fraction in organic amorphous form (Al-p) was also more dominant than Al in the inorganic amorphous form (Al-po) at horizon layer of 0-15 cm, while at horizon laeyer of 15-120 cm the Al-po form was higher than Al-p. Al fraction in the form of organic amorphous had higher bond compared with Al form of organic amorphous in the soil layer of 0-120 cm.

摘要台湾凤仙兰(Anoectochilus formosanus)是兰花的一种，被称为“宝石兰花”，在中国大陆和台湾都被用作民间药物。本研究旨在探讨不同外植体及生长调节剂TDZ和BAP对台湾凤尾兰体外形态发生的影响。结果表明:不同外植体对植后12周的愈伤组织百分率和芽形态发生、植后3周至12周的不定芽数、不定芽长和愈伤组织直径均有极显著影响。愈伤组织形态发生的最佳外植体为茎尖外植体(50%)，茎部形态发生的最佳外植体为副芽和节间外植体(100%)。第二节间外植体不定芽数量最多，平均芽数为7.62个。腋芽外植体的不定长最佳，平均茎长为1.16 cm;茎尖外植体的愈伤组织直径最佳，平均茎长为2.2 mm。植物生长调节剂TDZ和BAP在植后10周对不定长有极显著影响，在植后11周和12周对不定长有显著影响。种植12周后，0.25 mg L -1 TDZ + 0.75 mg L -1 BAP的不定长为1.13 cm /外植体。0.75 mg L -1 TDZ + 0.25 mg L -1 BAP处理对愈伤组织和芽部形态发生的影响最大。使用不同类型外植体与组合植物生长调节剂对台湾凤仙花的体外形态发生无交互作用。
