Marigold ((Tagetes patula), crotalaria (Crotalaria juncia), rapeseed plant (Brassica rapa) and oat (Avena sativa) as antagonistic plant and tomato (Lycopersicon esculentum), CL1104 variety as control, were evaluated to determine the effect on southern root knot nematode population in pot experiment at Tsukuba, Japan in year 2010. Completely Randomized Design (CRD) with three replications was used. Initial juvenile population was 30.0±2.8 per 20g soil. The juvenile nematode population was counted 63 days after transplanting and biomass of plants was incorporated in soil. Population was again counted 11 days and 13 day after biomass incorporation. At final count of Juvenile nematode population, it was found highest in tomato (66.6 /20g soil). Highest control was achieved in marigold (2.3 juvenile/20g soil) followed by crotalaria (3.0 juvenile/20g soil. Marigold and crotalaria followed by oat in rotation with tomato were observed as best antagonist plants to control Southern root knot nematode.

Generative Phase

Reproductive traits determine the selection method in plant breeding. The benggala grass of the Hamil cultivar was thought to be apomictic; thus, a study was conducted to determine its reproduction. The research began by studying the morphological characters, continued with observing the generative phase and seed production of the cultivar planted from seeds (generative) and from pols (vegetative). The experiment was conducted in the greenhouse of the Research Institute of Animal Production. The experimental design was a completely randomized design with ten replications, and the treatments were different types of plant materials: seeds and pols. The Hamil cultivar taken from RIAP Collection was planted in pots with a diameter of 40 cm and a height of 30 cm. The results showed that most of the morphological characters of the Hamil cultivar planted from seeds and from pols were not different (P >0.05), so it was presumed that they were apomictic. The difference in morphology was only in the length and width of the flag leaves and the length of the internodes, where the cultivars planted using seeds were higher. The production of seeds, pithy seed weight, and seed germination of cultivars planted using seeds were higher (P <0.05). Further research is needed to determine the apomixis properties based on cytologically Hamil cultivars.   Keywords: apomixis, benggala grass, morphology, plnting material; seed

In Brazil, eggplant and gilo are important for the economy of small-scale farms located mainly in the southeast states and other regions, with a significant production volume year-round in the wholesale local markets. However, these species are very susceptible to root-knot nematodes, and there are few or almost none known sources of resistance. The objective of this studywas to prospect sources of resistance to root-knot nematodesin eggplant, scarlet eggplant (gilo), as well in interspecific hybrids between these species and with wildSolanumspecies, to be used as rootstocks. In the first experiment, in 2013,10 eggplant accessions, a hybrid between eggplant andgilo, and a Solanum stramonifoliumxeggplanthybrid, were evalu41atedfor theirreaction to Meloidogyne enterolobii. In the second, in 2016, 20 accessions of gilowere evaluated for their reaction to M. incognita, M. javanica,and M. enterolobii.. And in the third experiment,in 2017,one access and two experimental eggplant hybrids, and one Solanum scuticumx eggplant hybrid, were evaluated for their reaction to M. incognita, and M. enterolobii. All the trials were stablished inagreenhouse, and characters related to root infection were evaluated in a completely randomized design with six replications of one plant per pot, usinga 1.5 L pots filled with a mixedsubstrate inoculated with each nematode species.Itwas found thatall eggplant accessions were susceptible to M. incognitaand M. enterolobii, however, BER 3150 presented lower susceptibility to M. incognita. The gilogenotypes CNPH 056, CNPH 070, CNPH 220,and CNPH 363 shownbetter response to M. incognitaand M. javanicathan the susceptibility pattern, the tomato 'Rutgers'. Other giloaccessions CNPH 070, CNPH 219,and CNPH 387 showed better or equivalent response thanthe resistant tomato 'Nemadoro' for M. enterolobii.4-the BER EG203 x S. scuticuminterspecific hybrid can be recommended as a rootstock for eggplant susceptible to M. incognita, as well the wild S. stramonifoliumvar. inerme species for M. enterolobii.

<p>Shallot is a high value commodity for Indonesian people. The rate of shallot production is considered quite slow considering of the increasing population, income, and the area of shallot cultivation. On the cultivation of shallots common obstacle of Ditylenchus that cause damage to the stems and shallot bulb. The dust of tobacco and vermicompost waste is known to suppress the development of nematodes. This study aims to examine the use of tobacco ash waste and vermicompost on the population of Ditylenchus nematodes as well as the growth and yield of shallot. This research was conducted at Faculty of Agriculture, Sebelas Maret University (UNS) Surakata in August to December 2016. The study was performed using Completely Randomized Design (CRD) with treatments in the form of tobacco dust, vermicompost, combined tobacco dust and vermicompost and control treatment. Data were analyzed using variance test (F test) with 5% level. If the result shows significant effect then followed by DMRT of 5% level. The result of this research showed that the use of combination of tobacco ash waste and vermicompost could decrease nematode ditylenchus population in the soil. The use of tobacco ash waste could decrease total of parasite nematode population on plant tissue. The treatment didn’t give any effect to shallot’s yield. Shallot’s yield was not influenced by the existence of nematode ditylenchus and another on plant tissue.</p>

SUMMARY This study evaluated the addition of inoculants on the aerobic stability, nutritional value, and fermentation and microbiological profiles of white oat silages (Avena sativa L.). The trial was carried out in a completely randomized design with three treatments and six replicates. The treatments consisted of three ensiling approaches: oat (O); oat with homofermentative bacterial inoculant (OB); and oat with bacterial-enzymatic inoculant (OBE). The aerobic stability was 9 days for silage O and 14 days for silages OB and OBE. The non-fiber carbohydrates (NFC) decreased (16.67 to 14.05% DM) and the crude protein (CP) did not change (mean of 8.98% DM) during the aerobic exposure in all silages. The buffering capacity (BC) decreased, while pH and the ammonia nitrogen (NH3-N) increased during the aerobic exposure in all silages. Independent from the aerobic exposure period, BC of OBE silage was higher than O silage (29.67 vs. 24.80 meq/100 g DM). Lactic acid bacteria count in OB silage (7.83 log CFU/g) was higher than in O and OBE silages (5.24 log CFU/g, on average). Also, the OB silage showed high enterobacteria count compared to OBE silage (2.49 vs. 0.76 log CFU/g). The inoculation with Lactobacillus plantarum, Pediococcus acidilactici and amylase enzyme at the dose of 1×105 CFU/g does not improve the aerobic stability, nutritional value and the fermentation and microbiological profiles of oat silages.

<p>In Vitro Conservation of Pomelo (Citrus maxima (Burm.)<br />Merr.) cv Srinyonya Using Osmoticum and Retardant.<br />Iswari S. Dewi, Gani Jawak, Ika Roostika, M. Sabda,<br />Bambang S. Purwoko, and Widiati H. Adil. Pomelo is an<br />underutilized citrus fruit with a potential for commercialization.<br />Only some cultivars have been conserved ex situ, such<br />as in home yards or in botanical gardens. Such collections<br />are vulnerable to biotic and abiotic hazards. The goal of the<br />experiment was to study the effect of osmoticum (sorbitol)<br />and retardant (ancymidol) on in vitro growth of pomelo.<br />Four-leaf in vitro shoots of pomelo cultivar Srinyonya were<br />used as plant materials. Murashige-Skoog (MS) medium was<br />used as the basal medium for the culture. The trial was<br />arranged in a completely randomized design with three<br />replications. The treatments consisting of MS + sorbitol (0,<br />20, 40, and 60 g/l) and MS + ancymidol (0, 1, 3, and 5 mg/l).<br />The results indicated that based on plant height, number of<br />new leaves, and visual plant architecture, sorbitol treatments<br />from 20-60 g/l retard the growth of the pomelo plant significantly.<br />On the other hand, ancymidol did not inhibit the<br />pomelo growth significantly, but it was a suitable osmoticum<br />for improvement of in vitro plant vigor, increasing green<br />color of leaf, and increasing root initiation. Leaf senescence<br />of in vitro plants cultured on media containing sorbitol 40<br />and 60 g/l began 20 week after storage. The best medium for<br />conservation of pomelo cv Srinyonya was MS + 20 g<br />sorbitol/l.</p>
