Abstract

ABSTRACT Efectivity Test for Some Extraction Techniques and Dry Heat Treatment on Tomato Seed (Lycopersicum esculentum Mill.) This experiment aimed to obtain the most effective extraction method and determine the effect of dry heat treatment to produce high quality tomato seeds. The design used was completely randomized design with 3 treatments and 9 replications. The treatments include: (1) Bl : fresh tomato seeds taken, immediately dried to 5% moisture content, (2) Ba: fresh tomato seeds taken, then soaked in water for 24 hours, dried to 5% moisture content, (3 ) Bh: fresh tomato seeds taken, then soaked in a solution of 2% HCl for 2 hours, then dried until the moisture content of 5%. Seeds obtained from each extraction technique is divided into two lots, one lot for Dry Heat Treatment (DHT) and the other one lot for Non Dry Heat Treatment (NDHT). The variables measured were the number of seed moisture content of 5% by weight of unity, purity of the seeds, the total viability, potential viability, vigor speed germination, and seedling growth vigor. The results showed the significant diference between extraction treatment to all of variables tested, while the granting of DHT on the seed does not provide a response to tomato seed quality, on all variables tested. Bh extraction treatment showed the best results with the highest values  on all of variables tested.   Key word : tomato seeds, extraction, dry heat treatment, viability and vigor.

Abstract

ABSTRACT The Test of Natural and Synthetic Fungicides Effectiveness in Controlling Fusarium Wilt of Tomato Plants Caused by Fusarium oxysporum f.sp. lycopersici Fusarium wilt caused by Fusarium oxysporum f.sp. lycopersici is one of important diseases in tomato plants. The emersion of the disease can result in huge loss for farmers. The use of synthetic fungicides that has been widely utilized all this time by farmers to control diseases caused by Fusarium oxysporum f.sp. lycopersici has adverse environmental impacts, therefore it is required biological fungicide that is more environmentally friendly. This study is purposed to testing the effectiveness of some natural fungicides and synthetic fungicide, is like a betel leaf, Trichoderma harzianum fungus, Klebsiella pneumoniae, and benomyl for suppress F. oxysporum f.sp. lycopersici and restrained Fusarium wilt diseases . The result of this study shows that the biological fungicide of betel leaf extract can inhibit the pathogenic F. oxysporum f.sp. lycopersici by 76.11 % and the percentage of inhibition potency of other benomyl fungicides reaches 61.11 % , while Klebsiella pneumoniae is by 54.42 % , and 20.98 % for Trichoderma harzianum on PDA medium. The result of field test shows that the extract of betel leaf can suppress Fusarium wilt by 5 % , T. harzianum , benomyl and K. pneumoniae are able to suppress Fusarium wilt respectively by 2.5 %. The use of T. harzianum and K. pneumoniae as biological control has the same effectiveness with synthetic fungicide in order to suppress Fusarium wilt.   Keywords: fusarium wilt, fusarium oxysporum f.sp. lycopersici, biological fungicide

Abstract

AbstractTomato Seed (Lycopersicum esculentum Mill.) Storability of Some Extraction Techniques Results                 Shelf life tomato seeds produced by different seed extraction techniques studied using completely randomized design ( CRD ) with three treatments of seed extraction technique and nine replicates. Three seed extraction techniques used are: extraction technique with 2 % HCl, washed with water extraction techniques, and extraction techniques with immersion in water for 24 hours. The seeds are dried until the moisture content ranges from 5 %, then stored at room temperature. Observations before storage include: seed moisture content, the amount of seed moisture content of 5 % per 5 g of seeds, seed purity, germination and speed of germination. Observations during storage include: seed moisture content,  germination and speed of germination. The results showed that the extraction technique of soaking seeds with 2 % HCl able to produce seeds with the lowest percentage of impurities so that the absorption of moisture during the storage period was also the lowest. Extraction technique of soaking seeds with 2 % HCl able to maintain the viability of the seed germination above 80 % until the 12 -week storage period at speeds high enough to germinate. While the seeds of other extraction techniques which have a shorter shelf life. Further research on the storage technique that is able to maintain the viability and vigor of tomato seeds for a longer shelf life.   Key words : Tomato seeds, extraction, seed storage, viability, vigor

Abstract

ABSTRACT Effect of Infection of Some Viruses to the Decresing Yield on Rawit Pepper (Capsicum frutescens L.) This study aims to identify the types of viruses that infect the plants of chili pepper ( Capsicum frutescens L. ) in Kerta village, and to know the influence of some kind of viruses infection on yield decline. To verify the type of virus is done by taking a sample of the pepper plant leaf showing symptoms of the virus that has been demonstrated through serological and molecular tests. The results of this study indicate that the mosaic symptomatic chilli pepper plants were infected by some kind of virus such as CMV, TMV, and ChiVMV. Chilli pepper shows asymptomatic yellow were infected by the PepYLCV and chlorosis were infected by Polerovirus. The result of fruit chili harvest were showed the higher yields on the healthy plants with average 16.01 tonnes/ha, while the chilli that showed chlorosis symptomps were 8.42 tonnes/ha, and yellow symptomps were 3.07 tonnes/ha. The lowest were in the plants that shows mosaic symptomp with average 2.52 tonnes/ha. The virus infection caused the losses of yield of 47.40% in chlorosis symptomatic plants, 80.82% in the yellow symptomatic plant and 84.25%, in the mosaic symptomatic plants compared to healthy plants. High yield loss in the mosaic symptomatic plants were caused by the highest infection on chiilli pepper that infected by some kind of viruses.   Keywords : Chili pepper , mosaic, chlorosis, and yellow
