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

Abstract

The burned peat in the farmland, Kalampangan Village have changed quite dramatically, such the water level is inundated during the rainy season and very dry during the drought season. Such conditions could be affecting the process of decomposition and chemical properties of peat and peat water associated with the availability of nutrients, especially nitrogen. This study aims to determine how the effect of water levels on the status of N in the burned ombrogenic peat in the Kalampangan Village. This research was uses a method of incubation as long as 40 days with the hanging column with the differences of water levels are 0, -10, -20, -30, 10, 20, and 30 cm. Parameter chemical properties of peat and peat, namely pH, total N, organic C, ammonium, ammonia, nitrite and nitrate. Analysis of data of the chemical properties of peat and peat water was done by using ANOVA level of 5% and 1%, then also regression and correlation analysis. The results have showed that there was no significant effect on the chemical properties of water and peat due to the changes in water level. Incubated peats have a very acidic pH with a high positive correlation at drying and a low positive correlation at inundation, while the peat water was indicates a perfect positive correlation at drying and high negative correlation at inundation. Peat showed a high total N with a low positive correlation at drying and a perfect negative correlation at inundation, while the peat water was indicates a perfect positive correlation at drying and a high negative correlation at inundation. Ammonification and nitrification processes were occurring that indicated by the accumulation of NH4 + and NO3 in peat and peat NO3 dissolved in water, where were the results of the regression analysis contained pattern polynomial equations and linear patterns. The equation can be used to predict the concentrations of all three parameters due to the changes in peat water level in Central Kalimantan

Abstract

This study aims to determine the effect of organic mulch treatment and NPK fertilizer application in increasing the growth and yield of onions on ultisol soils. The study used a factorial randomized complete block design consisting of two factors. The first factor was the treatment of organic mulch consisting of 4 levels of treatment M0 = control, M1 = grass mulch, M2 = sawdust mulch, M3 = mulch fern. The second factor is NPK fertilizer consisting of 5 treatment levels N0 = Control, N1 = NPK (200 kg ha-1) or 15.0 g plot-1, N2 = NPK (300 kg ha-1) or 22.5 g plot-1 , N3 = NPK (400 kg ha-1) or 30.0 g plot-1, N4 = NPK (500 kg ha-1) or 37.5 g plot-1, repeated 3 times, so that obtained 60 trial plots. The study was conducted in March to June 2017, located at the Agricultural Counseling Center, Kuala Kurun Gunung Mas Regency. The results of the study showed that the interaction of organic mulch and NPK compound fertilizer did not significantly affect all observational parameters. The provision of organic mulch had a significant effect on plant height, weight tubers per clump and tuber weights per plot. The M1 (grass) treatment gave the highest plant height of 26.7 cm (5 MST) and tuber weights 229.7 g plot-1. The highest yield per tuber cluster in M2 (sawdust) is 24.7 g. NPK fertilizer application has a significant effect on plant height and tuber weight per clump. The N2 treatment (300 kg ha-1) gave the highest plant height of 25.3 cm, while the N3 treatment (400 kg ha-1) gave the highest yield on tuber weight per cluster of 24.5 g

Abstract

The study aimed to find out the correlation between the socio-economic characteristics of farmers with the adoption rate of combine harvester implementation in tidal swamplands farming system in Pulang Pisau Regency, Central Kalimantan Province. Pulang Pisau Regency was selected as a study site since the area is considered as one of the tidal swamplands rice-production centers in Central Kalimantan, and most of the farmers have used combine harvester. The data was collected by interview method to 52 selected farmer households based on simple random sampling. In order to determine the correlation, Rank Spearman (rs) test was used, and its significance was tested using t-test at the 0.05 significance level. It has been found that the adoption rate of combine harvester implementation was high. Moreover, some socio-economic characteristics related to the adoption rate were farmer experience, age, non-formal education, land area, and capital source. However, there was no correlation between formal education with the adoption rate of combine harvester implementation in tidal swamplands farming system in Pulang Pisau Regency
