Abstract

Research to study the effect of application of rock phosphate (RP) enriched with SP36 to soybean on Ultisol was conducted at ILETRIs green house from July to October 2008. Treatment consisted of combination of rock phosphate from Lamongan and Bojonegoro at rates of 162 kg P2O5/ha with three rates of SP36 (0, 9, 18 and 27 kg P2O5/ha). The treatments were arranged in randomized complete block design and replicated three times. The result showed that application of RP from Lamongan and Bojonegoro to Ultisol Lampung at rates of 162 kg P2O5/ha increased soil pH by 0.3 and 0.5, available P (Bray 1) by 400% and 823% respectively compared to check.Highest soybean yield was attained by application of RP from Lamongan combined with SP36 at rates of 18 kg P2O5/ha or RP from Bojonegoro combined with SP36 at rates of 9 kg P2O5/ha which yielded 4.98 and 5.21 g/pot respectively. This result indicated that RP from Lamongan and Bojonegoro can be applied directly as P fertilizer for soybean in acid soil, and combining them with SP36 will increase their effectiveness.Keywords: rock phosphate, SP36, soybean, ultisol

Abstract

One of the obstacles in the efforts to increase soybean production in Indonesia is disease such as damping off which is caused by Sclerotium rolfsii. In East Java, the intensity of S. Rolfsii reached approximately 8.61% that spread all over Indonesia region, even in our neighbor countries such as Malaysia, Thailand and the Philippines. This research was carried out to determine the efficacy of Actinomycetes and VAM (Vesicular Arbuscular Mycorrhizal) against damping-off attack and the diversity of microorganisms in rhizosfer. Research conducted in the laboratory and screen house on Plant Protection Department, Faculty of Agriculture, University of Brawijaya and in Lawang District Malang. Observation variables include level of pathogen attack and infection rate of dampingoff pathogen. Plant height, number of pods, pod weight, seed weight and weight of 100 seeds from each treatment, diversity and identification of microorganisms in rhizosphere were also observed. The results showed that Actinomycetes and VAM application could decrease the percentage of plant death due to damping-off.  Application of Actinomycetes and VAM gave effect on microorganism diversity of Ratai Rhizosphere but not on Wilis. Keywords: Sclerotium rolfsii, vesicular arbuscular mycorrhizal, actinomycetes, and rhizosphere

Abstract

Oil palm plantation in Langgikima was mostly grown in soils derived from ultramfic rocks which contain low productivity. Therefore, a study was required to determine the charac-teristics of soils evolved from ultramafic rocks evaluated from the aspects of soil formation and classification as well as land suitability for oil palm extensification. Soil observation in field had been carried out in locations of oil palm plantation with slope gradient < 15%, with ultramafic bedrocks (harzburgite, serpentinite, and olivine websterite). Soils from ultramafic rocks were characterized by almost acid to neutral soil reaction, poor nutrient content available (N, P, and K) and exchangeable base cations, with very low to low CEC, low to medium BS, and clay minerals dominated by goethite and magnetite. Soils from harzburgite and serpentinite rocks were classified as Acrustoxic Kanhaplustults while those from olivine websterite rocks were classified as Rhodic Kanhaplustalfs. Nowadays, soils from ultramafic rocks were unsuitable (N2) for oil palm with the very low level of available P as the main limiting factor. Therefore, efforts on soil management were necessary to be performed by adding suitable organic materials and fertilizers based on soil characteristics and crops’ needs.Keywords: soil characteristics, ultramafic rock, oil palm

Abstract

Bacterial wilt on tomato caused by Ralstonia solanacearum is a crucial disease, because it can reduce yield until 50%. The aims of this research were: 1) to find out biopesticide formula for Bacillus sp.growth, 2) to test Bacillus sp. against R. solanacearum in vitro, 3) to test potassium fertilizer combined with Bacillus sp. for enhancing tomato resistance to the bacterial wilt disease. The research was conducted in 2 steps i.e to test the persistence of Bacillus sp. In biopesticide formula, and to test the best combination of both potassium and the Bacillus sp. biopesticide. The results showed that Bacillus B298 was the best isolate in its persistence on the biopesticide formula of organic growth medium+CaCO3+CMC 1%+mannitol 1%, and in inhibiting R. solanacearum. The best biopesticide formula for the Bacillus sp. persistence was growth organic media+ CaCO3+CMC 1%+mannitol 1%. Bacillus sp. was able to increase tomato resistance to the bacterial wilt disease from the category of susceptible to be tolerant and becoming resistant.   Keywords: tomato, Ralstonia solanacearum, potassium and Bacillus sp.

Abstract

Providing virus free potato seeds in order to increase potato production in Indonesia could be carried out by using microtuber resulting from microcutting. The growth of single node microcutting potato can initiate microtuber formation when growth inhibiting substances such as alar in combination with dark photoperiod treatment is applied. This study was aimed to elucidate the effect of alar and dark photoperiod on the date of microtuber emergence and production. The experiment was arranged in a factorial Randomized Completely Block Design in which alar concentrations i.e. 0, 10-3, 5 x 10-3, and 10-2 mg/L, served as factor I, and dark photoperiods i.e. 16, 20, and 24 hrs/day, were used as factor II. Each treatment combination was replicated three times giving rise to 36 experimental units. Data were analyzed using ANOVA (F test) followed by Duncan Multiple Range Test (DMRT) when significant effect of the treatments existed. The results showed that alar and dark photoperiod affected individually on the date of microtuber emergence, while the best alar concentration to increase microtuber production was 10-3 mg/L with 10.67 microtubers/cutting. Dark period has no significant effect on the induction of potato microtuber. Keywords: potato microtuber, alar, dark photoperiod

Abstract

The objectives of this study were: 1) to identify the mosaic symptom severity and the incidence the virus and relate these to soybean yield reduction is four regions of East Java; 2) diagnostic of the symptom using Indirect ELISA, RT-PCR and electron microscope observation. Results from experiments indicated that soybean plants infected with SMV and CMMV, alone or in combination produced mosaic symptom. Incidence of the virus, as judged by symptomatology, ranged from mild to severe infection the percentage of plants being from 13.42-30.10%. Soybean plants with mosaic symptom caused SMV from an early stage of development (14-28 days after planting). Soybean mosaic virus belongs to the virus family Potyviridae. Specific DNA fragment of 1687 bp was successfully amplified from soybean infected by SMV isolate Ngawi, Madiun, Magetan, and Ponorogo. Specific DNA fragment of 1385 bp was successfully amplified from SMV by CI coding region. The mosaic symptom on soybean plant (28-42 days after planting) caused CMMV. Flexious virus particle 650 nm in length was observed on electron microscope. It caused local lesions on Chenopodium amaranticolor, but not detected by I ELISA with antiserum SMV and RT-PCR with universal primer. Keywords: SMV, CMMV, I.ELISA, RT-PCR.

Abstract

One of the weaknesses of the groundnut is the easiness to be infected by fungi, especially Aspergillus flavus that produces aflatoxin. Seed from the field experiments for all step of selection (F5 until to multilocation yield test) after processed then stored for 3 and 6 months, further tested their respons to A. flavus using a standard method. Examined for seed coat resistance to colonization of A. flavus were carried out in laboratory ILETRI (Indonesian of Legume and Tuber Crops Research Institute) since years of 2002 to 2006. Stability performance of resistance to A. flavus was analyzed with regression technique. Performance of resistance to A. flavus of selected lines tested were not consistant among 16 of testing envoronments. Among genotypes were also sigficantly different response to A. flavus invasion from location to location, indicated that those performance of some lines were not stable, except line of MHS/91278-99-C-180-5. The highest pod yield was occupied by line of J/91283-99-C-90-8 and stable, however it's resistance to A. flavus did not stable. The resistance of J/91283-99-C-90-8 to A. flavus antil to three months after after seed strored similar with variety of J-11. Keywords: groundnut, Aspergillus flavus, aflatoxin
