Abstract

ABSTRACTThe Sclerotium Rot Disease is highly destructive to the scallions cultivation in the peat soil. Theantagonistic fungi isolated from the rhizosphere and the endophytes of healthy plants, have beenproven to be able to reduce Sclerotium rolfsii. The aim of this study was to evaluate thecharacteristics of antagonistic fungi from rhizosphere and endophytes of Scallions to S. rolfsii in- vitro in the laboratory. The purpose of this study was also to perform the suppression test on theintensity of Sclerotium rolfsiiRot Disease in planta in the peat media in the screen house. Thisresearch it was shown that genus Fusarium, Penicillium, Aspergillusas antagonistic fungi, wereidentified from the endophytes, meanwhile genus Trichoderma, Penicillium dan Aspergillus sp. were identified from the rhizosphere. Trichoderma Rz-1 and Trichoderma Rz-3 isolated from therhizosphere was shown to have the highest antagonistic activity by 94,4 %, followed by AspergillusEd-2, which was isolated from the endophytes by 83,8%. In planta on peat media, TrichodermaRz-1 was capable to demonstrate 82,19% of antagonistic effect and it could suppress SclerotiumRot Diseasehence it produced the fresh weight of the plant highest to 19gcluster-1. Taken together,the result of this study showed that Trichoderma Rz-1 isolated from rhizosphere has been proven tobe the most beneficial to reduce the Sclerotium rolfsii on Scallions as a biological control agent,especially in peat soils.Keywords: biocontrol, rhizosphere,endophyte, scallions, Sclerotium rolfsii

Abstract

ABSTRACTLiquid organic fertilizer is able to provide nutrients from leachate extract (liquid) as a result ofchanges in worm metabolism, growing media or residual worm feed as a result of the compostingprocess. This study aims to determine the interaction between feed type with worm colony weightas well as the influence of worm weight and type of feed on the quality of L. rubellus compostliquid organic fertilizer. The research was carried out at the experimental field of the Department ofAgriculture and in the analytical laboratory of the University of Palangka Raya using completelyrandomized design (CRD) with 3x3 factorial pattern. The first factor was colony weights of L.rubellus (C1 : 50 g, C2 : 75 g and C3 : 100 g) and the second was types of feed (P0 : control, P1 :green vegetable waste and P2: sedge-grass leaves). The results showed that 100 g worm colonyweights with feed from alang-alang leaves produced the highest Nitrogen nutrient (18.33 mg g-1),on phosphorus nutrients the interaction was not significant but had a significant effect from thetreatment of feed where the green vegetable waste produced the lowest phosphorus nutrients(85.67 mg g-1), but the treatment without feed (control) and sedge-grass leaves (Imperata cylindica)and the treatment of worm colony weight were not affect on the quality of L. rubellus compostliquid organic fertilizer.Keywords : Colony Weight, Feed Type, Liquid Organic Fertilizer, Lumbricus rubellus
