Abstract

ABSTRACTRice as a staple food for most of Indonesia's population,their needs increase withincreasing population, conversely production decreases. One effort to meet theneeds of rice is by planting upland rice in dry land. Ultisol is the most extensivedry land in Indonesia. The yield of upland rice in Ultisol is very low, this iscaused by various problems including acid reaction, high Al saturation and Pfixation, 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 andnutrient availability. The purpose of study was to study the effect of the interaction of rice husk ash and natural phosphate in increasing the growth andyield of upland rice (Oryza sativa L.) on Ultisol medium. The study was conducted at the Faculty of Agriculture greenhouse, University of Riau fromMarch 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 P2O5 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 P2O5 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 P2O5 ha-1 natural phosphate).

Abstract

ABSTRACTThis research aimed to selection the phenotype and molecular of rice lines (Oryza sativa L.) containing Pup1 and Alt loci at various concentrations of Al and P elements in yoshida nutrient solution. This research was conducted from November 2018 to February 2019 at The Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development Bogor. The phenotype study used a Split Plot Design with two factors and repeated three times. The first factor was the variation of Al×P concentrations consisting of eight levels and the second factor was the variation of rice lines consisting of twenty levels. The molecular study used three primers to detect the rice lines with Pup1and Alt loci. The results of the Yoshida nutrient solution showed that the A4 level of Al×P concentrations (0 ppm of Al×15 ppm of P) had the best average of other levels. In rice lines with Pup1 loci G4 [10B (B4-SK4)] showed the highest average on the root dry-weight parameters. In rice lines with Pup1 and Alt loci G11 [35(21(B15)-3] showed the highest average on the root dry-weight parameters at the A2 level of Al×P concentrations (0 ppm of Al×5 ppm of P) for Pup1 loci and A6 level of Al×P concentrations (60 ppm of Al×5 ppm of P) for Alt loci. In the molecular study, three primers can detect the rice lines that contained Pup1 and Alt loci. K46-2 specific primer detected the Pup1 loci with thecomparison of Kasalath rice variety. RM12031 and RM1361 primers detected the Alt loci with the comparison of Dupa rice variety.

Abstract

ABSTRACTThe 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. Pavailability 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 wasrice husk consist of 4 levels (0, 1,5, 3, and 4,5 ton ha-1). The second factor wasrock phosphate consist of 3 levels (0, 25, 40 kg P2O5 ha-1. The results showed the application of rice husk dose of 3 ton.ha-1 and rock phosphate dose of 25 kg P2O5 ha-1 increased Si and P uptake, P uptake efficiency, the root volume, dry weight, root canopy ratio, and plant growth rate.

Abstract

ABSTRACTOrchid plants are one of the ornamental plant commodities that have no foodreserves in their seeds and have very fine and small seed sizes making it difficult to propagate naturally. One alternative for the propagation of this plant is to carry out vegetative propagation in vitro or tissue culture. The success of plant tissue culture can not be separated from the role of media composition used. Leaf fertilizer is one of the alternative media that can be used as media material in orchid plant tissue culture because leaf fertilizers contain macro and micro nutrients that can provide nutrient intake to explants to support the growth and development of these explants. Propagation of Dian Agrihorti Dendrobium orchid plant in vitro through callus proliferation using different brands of leaf fertilizer media namely leaf fertilizer hyponex brand and growmore brand. The results of the observation showed that the most proliferative Embryogenic Callus and Proliferation Rate were produced from the treatment of adding 4 ppm growmore, namely 88.42% and 322.41%. For the best color callus parameters generated from the control treatment.

Abstract

ABSTRACTThis study aimed to: (1) study the effect of interactions between gibberellin concentration and several wetland rice varieties on conditions of high salinity stress on growth and yield, (2) gibberellin concentration and lowland rice varieties which have the best influence on growth and the results of lowland rice. The research was carried out at the screen house of the Faculty of Agriculture, Winaya Mukti Tanjungsari University - Sumedang Regency with altitude 850 m above sea level. The time of the study was carried out in December 2014 until April 2015. The study used a factorial Randomized Block Design method, which consisted of two factors: gibberellin concentration and several varieties of lowland rice in high salinity stress. The first factor is the concentration of gibberellin (G), consisting of four levels: g0 = soaking the seeds for 24 hours in giberelin 0 mgL-1 = soaking the seeds for 24 hours in gibberellins 20 mgL-1, g2 = soaking the seeds during 24 hours in gibberellins 40 mgL-1, g3 = soaking the seeds for 24 hours in giberelin 60 mgL-1. The second factor is rice paddy variety (P), consisting of eight levels: p1 = Inpari 10, p2 = Inpari 20, p3 = Inpari 25, p4 = Inpari 26, p5 = Inpari 27, p6 = Inpari 30, p7 = Inpara 4, and p8 = Banyuasin. The results of the study indicate that here is an interaction effect between gibberellin concentrations and some lowland rice varieties in high salinity tresses against root drop ratio at ages 7, 35 and 49 HST. Rice varieties independently affect the age of harvest and the weight of 1000 seeds. There is a concentration of gibberellins and lowland rice varieties that produce the best growth and yield in high salinity stress.
