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 goal of this research was to determine the growth response and yield of corn plants (Zea mays L.) towards the application of chitosan organic fertilizer and nitrogen fertilizer. This research used randomized block design which consists of two factors. The first factor was the concentration of chitosan organic fertilizer whith four levels: 0 ppm/ plant, 10 ppm/ plant, 20 ppm/ plant, and 30 ppm/ plant. The second factor was the dose of nitrogen fertilizer with four levels 0 g/plant, 5 g/plant, 10 g/plant and 15 g/plant. There was 16 combinations of treatments. Each treatments was replicated three times to obtain 48 experimental units. Parameters observed were number of cobs per plant, number of seeds per plant and weight 100 seeds. The results of this research showed that application of chitosan fertilizer does not affect the yield of corn plants. Chitosan fertilization with a concentration of 10 ppm tends to show higher yields on the parameters of the number of cobs (2.25 cobs) and weight of 100 seeds (35.00 g). The application of nitrogen fertilizer affects the yield of corn plants. Nitrogen fertilization with a dose of 15 g/plant increased the number of cobs (2.83 cobs) and the number of seeds per plant (647.75 seeds) compared to the control treatment. There is no interaction between chitosan fertilizer and nitrogen fertilizer on corn yields.

Abstract

Phosphorus is a macro essential nutrient for plants that are needed in large quantities third after Nitrogen and Potassium. Phosphorus acts as an activator of various plant metabolism enzymes and is a component of chlorophyll. Phosphorus is a necessary element in large amounts (macro nutrients), the amount of phosphorus in plants is smaller than nitrogen and potassium, but phosphorus is the key to plant life by absorbing phosphorus in the form of primary orthophosphate ions (H2PO4-) and secondary orthophosphate ions (HPO42-). In acid soils, the phosphate will be compounded in Al-P and Fe-P forms, whereas in alkaline soil, phosphate will be compounded with calcium as Ca-P forming a soluble complex compound. This research was conducted with the aim of evaluating the relationship and interrelations between the dynamics of phosphorus nutrients to some soil chemical properties on each acid soil profile horizon. This research was conducted in Laboratory of Soil Chemistry and Fertility Department of Soil Science and Land Resources Faculty of Agriculture, IPB. The soil samples used in this research were soil samples originating from the location of Neglasari Jasinga Bogor Village and Padasuka Village Maja Lebak District of Banten Province was taken per horison in soil profile. The results of the two land sites used showed that the dynamics of the availability of phosphorus nutrients. This dynamic was due to the presence of soil pH and aluminum solubility within each soil horizon. On the land profile of origin of Jasinga and lebak that the value of Al-dd would be high if the low soil pH value and available P value would be high if there was a decrease in soil pH value and the value of Al-dd soil.Keywords: acid soil, aluminum, phosphorus

Abstract

ABSTRACTThe toxicity of Al, Fe, and Mn is highly determined by the shape of the metalfractions. Therefore, the specific forms of Al, Fe, and Mn inside the soil are veryimportant 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.
