Abstract

In the recent years, basal plate rot (BPR) caused by Fusarium oxysporum f. sp.cepae (FOCe) is one of the important constraints of shallot production in Indonesia. This research aimed to study the potential of S-oxidizing bacteria (SOB) as biological control agents to inhibit FOCe and provide available-S to shallot on Andisols. An experiment in laboratory was conducted to evaluate the capabilty of SOB in oxidizing S in liquid medium and a pot experiment was aimed to evaluate the capability of SOB in providing available-S and inhibiting infection of shallot by FOCe in Andisols. All treatments were arranged by a Completely Randomized Design with three replications. The data were analyzed by F test, followed by Duncan’s Test.The results showed that the capability of oxidizing S in a liquid medium increased after the incubation for six days, with the highest concentration of soluble-S was taken from SOB2 isolate. The isolate provided the highest available-S, while the highest capability of decreasing the disease incidence was taken by SOB3 and SOB1+2+3. SOB3 isolates promoted the highest growth of shallot. So it has a tremendous potential if they are used as an inoculum of bio-fertilizer and biological control agent of BPR of shallot.

Abstract

This IbM program in collaboration with two partners, namely: (1) Breeders quail "Panjer Rino", and (2) Livestock Catfish "Dwipangga". Partner (1) is located in the hamlet of Gunung Sari, Ngringo village, district. Cork, Kab. Karanganyar, with a distance of about ± 3.5 km from Fak. Agriculture UNS. The problem faced by business partners (1) is the production of livestock waste quail (quail droppings) are very high, which is about 200 kg of waste per day (6 tons per month). Currently, the waste dumped directly into nearby rivers, contaminating the river water. Dirt quail very high in protein (17-21%). Natural nature catfish food is dirt ("telek"). The problem faced by partners (2) is a high cost to provide quality catfish feed. Catfish feed requirement per week reached 200-250 kg, with an average feed price Rp. 8.300, - per kg. Therefore we need an alternative feed supply, such as pellets of excrement quail that can be produced using animal manure quail. Azolla is the only genus of floating water fern. It can be used as green manure, Azolla is used to feed the fish because they contain high nutritional and floats that can be eaten fish or made pellets. The purpose of this activity is to address the key problems: Partner (1) ie quail livestock waste treatment technology that can be used to manufacture pellets. Partners (2) that address the high cost of feed catfish feed Azolla can use directly and make pellets of Azolla and dirt quail. The method used in this activity is to give guidance to partners and practice on: the use of quail dung to feed catfish; the practice of making pellets using quail dung mixed Azolla, Azolla maintain direct practice in catfish ponds and catfish farming. Outcomes that will result from the planned activities IbM are: pellets of excrement quail and Azolla for catfish feed and Azolla as catfish feed directly.

Abstract

Industrial waste supplies contains heavy metals such as Pb which will cause pollution in paddy fields. Remediation of paddy soil contaminated by Pb heavy metal must be done by simple, environmental friendly, cheap and sustainable technology, that is bioremediation. The purpose of this study was to study the effectiveness of bioremediation using Agrobacterium sp. I3 and compost as chelator combined by Mendong plant and NPK fertilizer, and learn the ability of Mendong in uptaking metal soil Pb. This was field experimental research, had a factorial patern, using Completly Randomized Block Design as the base design, with three factors: (1) NPK fertilizers (P0: no NPK fertilizers, P1: with NPK fertilizers), (2) Chelator (K0: no chelator; K1: with chelator Agrobacterium sp. I3 ; K2: with chelator compost); and (3) Plant (T0: without plant; T1: with Mendong plant). The results showed that Agrobacterium sp. I3 and compost were increasing Pb uptake in shoot, but decreasing Pb uptake in root. Mendong plant has highly ability in uptaking soil Pb, so decreased soil Pb, and effective as the phytoremediator. NPK fertilizer increased plant growth so increased Pb uptaken by plant. The highest Pb uptake was in treatment combination of NPK fertilizer + Mendong plant: 80.916 µg, followed by NPK fertilizer + Agrobacterium sp. I3 + Mendong Plant: 76.363 µg. The highest decreased of soil Pb (42.41%) was found in treatment combination of compost + Mendong Plant. Key words: Agrobacterium sp.I3, compost, Fimbristylis sp, Pb, phytoremediation

Abstract

The long-term use of excessive amounts of chemical fertilizers and pesticides adversely affects soil fertility, crop productivity, and biodiversity of soil and endophytes microbes. This study evaluated the ability of endophytic bacteria isolated from rice plants to enhance soil fertility, promote plant growth, and induce rice plant resistance on Alfisols treated with insecticide 10x usage dose (chlorantraniliprole 100 g L-1 and thiamethoxam 200 g L-1), and also assessed the diversity and population density of the associated phosphate solubilizing rhizospheric and endophytic bacteria. Three isolates of Burkholderia sp. YErOI-1 (I1), Bacillus sp. NErOI-2 (I2), Burkholderia sp. PElOI-3 (I3) and a mixture of three isolates (I4) were tested in combination with (P1) and without (P0) insecticide treatments in the pot cultivation of rice Inpari 32 using Alfisols in a completely randomized factorial design with three replications. The results showed that the control (I0P0) demonstrated higher plant growth compared to I0P1, indicated insecticide treatment resulted in toxicity effect. Among all the treatments, I2P0, I2P1, and I1P0 yielded the highest plant growth, whereas the lowest was indicated by I1P1. The rice associated phosphate solubilizing rhizospheric and endophytic bacteria indicated the highest population density and diversity index on the treatments I3P0 and I3P1 which significantly correlated with the highest P concentration and P uptake in these two treatments. Isolate I2 showed the strongest effect in inducing plant growth to insecticide resistance, in contrast isolate I1 showed no support in inducing plant resistance to insecticide. Further study is needed to examine the effect of the present assessed endophytes in other type of pesticide treatments.
