Abstract

The eruption of Mount Merapi had been giving adverse effect for the community, but on the other hand, there are great benefits in it such as the enrichment back to the land. Enrichment process in land with materials that are rich in nutrients is often known as rejuvenation. In general, the rocks containing certain minerals or mineral assemblages, which has large amount of the potential nutrient that can be used by plants in the form of weathered minerals. Therefore, it is a big question about the relationship between primer mineral deposits on Mount Merapi volcanic material with the potential nutrient for crop. The results showed that the identification of Merapi pyroclastic material derived from basaltic andesite magma with primary mineral content easily weathered the dominant form of plagioclase. Utilization of volcanic material as macromineral is easy to use, because the nutrient content of the existing potential in minerals included in the group of minerals that easily weathered.

Abstract

Andisols has relatively low phosphorus availability due to its adsorption by allophane. Phosphate solubilizing bacteria (PSB) increases the availability of P via release of adsorpted-P. The aims of this research were to determine: 1) anorganicP solubilization, 2) organic-P mineralization, 3) blocking of Andisols adsorption site, and 4) effective PSB inoculant. The research was arranged in completely randomized design, with PSB inoculant as treatment. Variables observed were solubleP, mineralize-P, adsorpted-P, pH, total acidity, PSB population, phosphatase and phythase activity, relative surface charge, and maize’s growth component. The result showed that PSB inoculation increased soluble-P from 30 to between 150 and 195 ppm P, increased mineralize-P from 23.7 to between 63.6 and 91.7 ppm P, and decreased P-adsorption from 95 to between 36 and 13%. PSB inoculation decreased the Andisols pH, increased the total acidity, PSB population, the phosphatase and phytase activity, and PSB had relatively high of relative surface charge (69%). The PSB inoculation increased maize P absorption in the range of 70 and 75 mg P plant-1, and increased relative agronomic effectiveness (RAE )between 145 and 150%. Liquid and solid PSB inoculant had no different effect in increasing maize growth. Keywords: Andisol, P release, phosphate solubilizing bacteria, phosphatase, phytase

Abstract

TITLE : EFFECT OF ARBUSCULAR MYCORRIZHAL FUNGI INOCULATION ON GLOMALIN, GROWTH AND RICE YIELD. The aim of this study was to measure the glomalin production, growth and yield of rice in upland rice fields. The research used Completely Randomized Design with four treatments: two sterilization levels (no sterilisatio and with sterilization) and two levels of mycorrhizae inoculation ( no mycorrhizae and with mycorrhizae). Mycorrhizae (5 g/pot) was inoculated before planting rice seeds. The results showed that Glomalin Total (GT) and Glomalin easily extracted (GEE) were higher in mycorrhizae inoculation, increased by 16% and 20% in non-sterile soil and 25% and 11% in sterile soil compared to non-mycorrhizae inoculation. The content of the GT ranged from 4.95 to 9.74 mg/g soil and GEE 0.99 to 2.78 mg/g soil. Plant height, tillers number and  the  grain yield was increased by mycorrhizae inoculation significantly. Soil sterilization could reduce the effectiveness of mycorrhizae inoculated.

Abstract

The aim of this study was to evaluate performance and in vitro digestibility of Guinea grass grown on saline soil. Yield, quality, and in vitro digestibility of Guinea grass cultivated on coastal area with crop populations of 10,000,20,000, and 30,000 plants per hectare. Experiment was conducted following randomized complete block design (RCBD). Higher crop population increased fresh and DM biomass production, crude protein (CP) yield, dry matter(DM) content, neutral detergent fiber (NDF), lignin, and hemicellulose content, but decreased CP content, and in vitro organic matter digestibility (OMD). The increased population had no effect on acid detergent fiber (ADF) and in vitrodry matter digestibility (DMD). It could be concluded that guinea grass was recommended to be planted in saline coastal area by addition of fertilizer 20 tons/ha manure, 3 tons/ha gypsum, and 50 kg N (239 kg ZA/ha) as source ofnitrogen.(Keywords: Forage, Salinity, Saline soil, Manure, Gypsum, Nitrogen source)

Abstract

The natural zeolite was treated with alkali (NaOH) solution and heating at 100 oC for 12 and 24 hours. The natural zeolite was collected from Gunungkidul, Jogjakarta, Indonesia. The series of NaOH solutions was 0.5, 1.0, 1.5, 2.5, 3.5 and 4.5 M. The final product of the reaction (precipitate) was designated as 'activated natural zeolite (ANZ)'. The cation exchange capacity (CEC) of the ANZ increased with increasing NaOH concentration up to 1.5-3.5 M. Treatment with NaOH 3.5 M and 12 hours in period of hydrothermal reaction resulted in a maximum CEC (395.6 cmol.kg-1). The maximum CEC also observed for treatment with NaOH 1,5 M, but consumed a longer time (24 hours). The increase in the CEC of the ANZ about 300 % higher than the original one. The XRD (X-ray Diffraction) peaks of the ANZ appear at 2.7, 3.2, 4.1, 5.1, 7.2 Ã…, this indicated a new crystalline matters (possibility phillipsite) present. Electron micrograph showed that the ANZ has a large cubic/prismatic structure with a perfect form.

Abstract

Rice quality is the dominant factor of rice. The quality of rice includes the weight percentage of head rice, amylose content and the quality of rice include flavor of rice, rice texture and rice aroma. Rice from different rice varieties will be different quality, so also the way of rice cultivation is also very influential on the quality of rice produced. This study aims to compare the quality of rice from various rice varieties under organically and conventional cultivations. The experiment was conducted on Organic and Conventional rice field in Kebonagung village, Imogiri, Bantul from September 2013 until January 2014 with Inceptisol soil type and altitude of 114 m . This research was designed with Randomized Completely Randomized Block Design which was arranged in a split plot consisting of 2 treatment factors and repeated 4 times. Factor I: Cultivation, namely organic cultivation and conventional cultivation and Factor II kinds of varieties that consist of IR64, Cianjur, Pandanwangi, Mentikwangi and Cisedane. Parameters observed included grain yield, percentage of rice head, amylose content, protein content, and rice quality including rice flavor, rice texture, and rice aroma. The results showed that (1) the yield of grain did not differ between organic cultivation and conventional cultivation. (2) Organic cultivation increased the heavy percentage of rice head of IR64 variety, (3) Organic Cultivation decreased the amylose content of Cianjur and Pandanwangi varieties, and increased the amylopectin level so the rice became more “Pulen” (4) Organic cultivation raises levels of IR64, Pandanwangi, Mentikwangi and Cisedane variety of varieties, (5) Organic cultivations tend to improve the quality of rice including taste, texture and aroma of rice
