Abstract

The research aims to study the use of fly ash for improving the growth and yield of rice in peatland. The peat soil material that used in this study was sapric weathering level. The field research was designed by using a completely randomized design. The treatment in this study was the application of fly ash consisting of six levels (0, 25, 50, 75, 100 and 125 g fly ash per pot), each treatment repeated 4 times. The results showed that the best plant growth and yield of rice were gained from the application of fly ash at the lower dose (25 g pot-1 and 75 g pot-1, respectively). The increase in fly ash dose (100 g pot-1 and 125 g pot-1) did not gave the highest rice yield (9.67% and 0.2% lower than the dose of 75 g pot-1) due to the macronutrients N, P and K as a limiting factor (only as a basic fertilizer).

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

The main problems of sweet corn cultivation in Ultisol medium are sour reactions, Al saturation and height P fixation, as well as low availability macro, micro nutrients especially Mo and Si. The provision of empty oil palm biochar is able to increase the growth and yield of sweet corn crops because the Biochar TKKS contains macro and micro nutrients such as N, P, K, Ca and Mg and also as a useful soil material to improve physical, chemical and biological properties of soil to increase pH, C-Organic, Ca, K, Mn, P, and mycorrhiza application be able to increase the availability of P so the fixation of P can be suppressed. The purpose of this research to learn the main influences of the Biochar TKKS, the main influence of mycorrhiza and the interaction of the growth and yield of sweet corn in the Ultisol medium. The experiment was conducted in the Experimental farm of the Agriculture Faculty, the University of Riau from May to August 2019.Research of experiments in the form of 4×3 factorial using Complete RandomDesign. The Biochar TKKS consists of four levels (0, 25, 3.75, 50 g polibag-1) asthe first factor, mycorrhiza consists of three levels (0, 10, 15 g plant-1) as thesecond, each repeated three times. The results of the study show that giving of the biochar TKKS dose 3.75 g polibag-1 and mycorrhiza dose 15 g plant-1 in theUltisol medium increased on plant height, straw weight, cob length and number of rows of each cob compared to no treatment.

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.
