Abstract

ABSTRACTThere are many shallot cultivars cultivated in Java with varying greatly morphological traits and yield. Morphological and yield variation indicate that there are genetic variation and varying in resistance to pest and disease. One of major disease that cause yield losses of shallot is Fusarium Basal Rot (FBR) caused by Fusarium oxysporum f. sp. cepae (Foc). The pathogen could cause yield losses of shallot in field up to 90%.The number of sixteen shallot cultivars were collected and studied for determining polymorphisms of nuclear based on Random Amplified Polymorphism DNA (RAPD) and the morphological traits. Potted research was conducted at greenhouse from December to February 2012, in Department of Agriculture, Universitas Gadjah Mada (UGM), Yogyakarta. Four shallot cultivars were selected for study the response to Foc under biofertilizer application. They were Kuning, Trisula, Tiron, and Crok cultivars. The field experiment was carried out from June to August 2012 at the Agricultural Training, Research and Development Station (ATRD/KP4) in Kalitirto, Sleman, Yogyakarta. The research design was split plot 4 x 4, with three replications. The plots consisted of shallot which cultivated in Foc inoculation, biofertilizer application, combination of Foc inoculation and biofertilizer application, and without any treatments. The subplot consisted of shallot cultivars. All data were statistically analyzed using the variance analysis. Standard error was tested to determine the significant differences among treatment means.Similarity coefficient among shallot cultivars as revealed by UPGMA cluster analysis of RAPD markers generated to molecular dendogram. The similarity of genetic dendogram ranged from 0.85 to 0.66 and separated of cultivars into two groups. Based on morphological analysis, there were variations of all variable that tested. Mophological dendogram made possible to identify four group.Fusarium Basal Rot (FBR) incidence caused by seedborne was 6.94%. Biofertilizer application could not decrease significantly FBR incidence but it could increase number of bulb per plant in Crok and Kuning cultivars. FBR incidence with 43.75% caused by Foc inoculation was significantly decreasing plant height, number of bulbs, diameter of bulbs, and length of bulbs. However, yield of shallot decreased significantly  from  1.05  kg/m2 to  0.63  kg/m2 when  the  shallot  plantation  was inoculated by Foc. The shallot plantation was inoculated by Foc under biofertilizer application did not show significantly decreasing FBR incidence and increasing the yield. FBR incidence and yield of Trisula, Crok and Tiron cultivars did not show difference significantly from Kuning cultivar as susceptible to Foc.Key words: cultivar, shallot, RAPD, Fusarium oxysporum f. sp.

Abstract

An ameliorant is a chemical that can be used to improve soil fertility. The improving agents include dolomite and steel slag. Steel slag is a by-product of the steel industry containing CaCO3, SiO2, CaSiO3, and MgO, which can be used to improve the growth and yield of rice plants. Dolomite, on the other hand, is a limestone rock containing MgO and CaO, which is useful in agricultural soils. This study aimed to determine the types and doses of ameliorants affecting the growth and yield of rice plants (Oryza sativa L.). The research was carried out at Sukadana Village, Ciomas Serang-Banten District. A non-factorial Group Randomized Design with seven treatments was employed in this investigation. The treatments include P0 = No treatment (control), P1 = 2 t/ha of dolomite, P2 = 2 t/ha of dolomite + 2.5 t/ha of steel slag, P3 = 1.5 t/ha of steel slag, P4 = 2.5 t/ha of steel slag, P5 = 5 t/ha of steel slag, and P6 = 7.5 t/ha of steel slag. Observation was made on steel slag characterization, plant height, the total number of tillers, the weight of 1000 grains, the amount of grain per clump, and the weight of dry-milled grain. The results showed that applying dolomite at 2 t/ha and steel slag at 2.5 t/ha could increase the weight of 1000 grains of rice, and applying steel slag at 1.5 t/ha could enhance the amount of grain per clump.
