Abstract

Title : The Uptake and Tolerance of Azolla to Chromium on Vertisols and Entisols at Various Water Levels. This research aims to study the effect of water level, soil kind, chromium concentration (Cr), and their interactions on uptake and tolerance of azolla to Cr. The research was done in March to May 2009 in the green house of Faculty of Agriculture, Sebelas Maret University, Surakarta. The research used completely randomized design (CRD) factorial with three treatment factors, they were: soil kind (Vertisols of Jatikuwung and Entisols Colomadu, Karanganyar), water levels (0; 2; and 7 cm) and Cr concentrations (0; 5; 10; 15; and 20 ppm). There were 191 g of Vertisols and 200 g of Entisols pass to 2 mm sieve put into plastic pot and watering at various levels according to the treatments. A gram of fresh azolla was spread on each pot and incubated for three weeks. Each treatment combinations were replicated three times. Sampling was taken at 1, 2, and 3 weeks after planting for azolla biomass, Cr uptake of azolla, available Cr, and Cr toxicities symptoms of azolla. The data analyzed statistically by Kruskal Wallis test at 95% level significant, followed with Mood Median test. The result shows that soil kind has no significant effect, while water level, Cr concentration, and treatment interaction contribute highly significant influence on uptake and tolerance of azolla to Cr. The highest uptake of Cr at the Vertisols was taken at 7 cm water level and 15 ppm Cr concentration, while at the Entisols was in 2 cm of water level and 15 ppm Cr concentration. Azolla most tolerance to Cr at treatment combination of 2 cm water level and 10 ppm Cr concentration in Vertisols, and at 2 cm water level and 5 ppm Cr concentration at Entisols.

Abstract

Title : P-solubilizing Fungi as Biological Control Agents to Increase Growth and Prevent Moler Disease of Red Onion. This research aim to obtain phosphate-solubilizing fungi have antagonistic ability to Fusarium oxysporum f. cepae, and increase soil available-P. The experiment was hold in April 2013 to February 2014. Antagonistic capability was observed in two stages i.e. in vitro test which was conducted in the Laboratory of Soil Biology and Biotechnology, while in vivo test in green house, Faculty of Agriculture, Sebelas Maret University Surakarta. The experimental design used was completely randomized design (CRD). The treatment factors of in vitro test were kinds of phosphate solubilizing fungi and incubation time with Pikovkaya liquid medium, while the treatment factor of in vivo test was isolates combination of phosphate solubilizing fungi. Each treatment combination was repilcate three times. The observated variable included soil available phosphate, shallot height, shoot dry weight, moler disease intensity, infection rate, and area under the disease progress curve. The research obtained 3 isolates of fungi with high potential as inoculums of P-solubilizing biofertilizer and biological control agents against moler desease of red onion. The resullt showed that mix of JK12 isolate (isolated from Entisol of Bantul District) and isolate of JK14 (from Andisol of Tawangmangu sub district) demonstrated the highest ability in solubilizing phosphate and suppressing moler disease of red onion.
