Swamp cabbage is generally consumed by the people of Indonesia and can be one of the restaurant’s menu [1]. Swamp cabbage is a plant that is relatively resistant to drought and has a broad adaptability to various environmental conditions plants, easy maintenance and has a short harvest period [2]. Swamp cabbage commonly grown in home gardens and some small intensively planted on dry land, so as to optimize the production of swamp is still lacking. Swamp cabbage contains complete nutrition, including protein, fat, carbohydrates, fiber, calcium, phosphorus, iron, sodium, potassium, vitamin A,B,C, and carotenoids [3]. Additionally, swamp cabbage serves as medicinal plants to cure constipation, soothe the nerves and the drug hemorrhoids [4]. Swamp cabbage production in Indonesia can reach 50.000-60.000 kg ha-1 [5]. Cultivated Swamp cabbage for 0.10 ha spent 16kg of seed planting swamp cabbage however slightly results are compared with other crops [6]. From the social and economic aspects, swamp has good prospects if developed towards agribusiness, but it does require effort in planting efficiency. The use rizobacteria (Plant Growth Promoting Rhizobacteria (PGPR)) as a biological fertilizer is the contribution of biotechnology in crop productivity improvement efforts. This was achieved by nutrient mobilization, growth hormone production, nitrogen fixation or activation of the mechanism of disease resistance [7,8]. Therefore, the evaluation of the ability of local Rizobacteria as bacterial growth driver needs to be done. If proven effective, the local Rizobacteria can be used as an alternative biological fertilizer (biofertilizer) on the cultivation of swamp cabbage in Indonesia. Efforts to reduce the use of synthetic fertilizers and pesticides are needed in moving towards environmentally sustainable agriculture. Lately, attention has focused on biological resources in improving health (resistance) of plants, through the role of beneficial soil microbes. Microbes that are beneficial to plants, such as Pseudomonas spp of the rizobacteria group can serve as fertilizer, as a means of biological control of plant pathogens and improve plant resistance (induced systemic resistance (ISR) [9]. Rizobacteria is a group of bacteria with the plant root zone habitat (rizosphere) which has been researched and proven to Agri Res & Tech: Open Access J 6(1): ARTOAJ.MS.ID.555679 (2017) 0023 Research Article Volume 6 Issue 1 - April 2017 DOI: 10.19080/ARTOAJ.2017.06.555679 Agri Res & Tech: Open Access J Copyright © All rights are reserved by I Ketut Widnyanass Abstract Research of “The effect of soaking seeds with the bacteria Pseudomonas alcaligenes to the growth of swamp cabbage (Ipomoea reptans Poir)” was conducted to determine the effect of seed soaking with suspense of P. alcaligenes isolate KtS1, TrN2 and TmA1 to the growth of swamp cabbage. This research is the development of research that has been done before on tomato plants. This study was designed with a Randomized Block Design and data analysis using SPSS v.17 for windows. The treatments were three types of isolates of P. alcaligenes, soaking time, and growing medium. The parameters observed were germination and other growth parameters. The results showed that seed soaking treatment with suspense P. alcaligenes cause germination 25% faster, higher crop up 24.4%, number of leaves more up to 23.15%, longer stems to 25%, longer roots up 46.90%, fresh stem weight higher up to 67.07%, dry weight oven stem higher up 84.21% if compared with control. The best treatment response was TrN2.6NB, soaking seeds of swamp cabbage with P. alcaligenes TrN2 for 60 minutes on medium NB (Natrium broth).
