Vermicompost products have gained a great importance in plant nutrition over the years. They are reported to have plant growth promoting effects both in horticulture and field crops. The nutritional value and chemical properties of vermicomposts highly depend on the feedstock used in their production. The aim of this study was to evaluate vermicompost manure, derived from the mixture of cattle manure and kitchen scraps, on seed germination and growth of tomato seedlings (Lycopersicon lycopersicum Mill.). Four solid vermicompost amendment rates of 0, 10, 20, and 30% were applied in plastic trays. Vermicompost application delayed and reduced seed emergence in all application rates, while in general, vermicompost substitution promoted growth tomato seedlings up to 20% of application rate. The results showed that vermicompost substitutions greater than 20% had adverse effects on seedling emergence and seedling growth parameters, which was attributed to high EC of vermicompost induced by cattle manure. Results suggest that both physical and chemical properties of the feedstock used for vermicompost production should be taken into consideration in order to sustain high vermicompost quality to ensure targeted plant growth for horticultural and agricultural purposes.

AbstractPenicilliumspp. are well known to produce a variety of beneficial metabolites for plant growth and survival, as well as defend their hosts from attack of certain pathogens. In this study, effects of culture filtrate of differentPenicilliumspp. were tested on tomato seeds. On the whole, presoaking of seeds in filtrates of the ninePenicilliumisolates tested, significantly increased seed germination when compared with the control seeds. Cultural extracts ofP. expensumandP. billiwere highly effective in growth promotion up to 90%. It was also observed thatP. implicatumandP. oxlalicamsignificantly enhanced the root growth in tomato seedling as compare to other species. In case of shoot length,P. verrucosum(3.38),P. granulatum(2.81) andP. implicatum(2.62) were effective. HoweverP. implicatumwas quite promising to increase shoot and root length in tomato seedlings. Where asP. simplicissimiumandP. citrinumwere leas effective on seedling growth. The plant growth promoting ability ofPenicilliumstrains may help in growth permotion in other plants and crops.Penicilliumspp. are already known for producing mycotoxin and enzymes. Plant growth promoting ability ofPenicilliumspp will open new aspects of research and investigations. The role ofPenicil-liumspp. in tomato plant growth requires further exploration.

Cladosporium species are active in protecting plants against different biotic and abiotic stresses. Since these species produced a wide range of secondary metabolites responsible for the adaptation to new habitats, plant health and performance, they are of great interest, especially for biostimulants in agriculture. Cladosporium sp. produces protein hydrolysates (PHs), a class of biostimulants, by cultivation on medium with keratin wastes (feathers) as carbon and energy sources. The aim of this study was to select a Cladosporium isolate with potential to be used as plant growth promoting agent. The characteristics of Cladosporium isolates as plants biostimulants were evaluated through several tests, such as: antagonism versus plants pathogens, effect on plant growth of secreted volatiles produced by isolates, secretion of hydrolytic enzymes, production of 3-indole acetic acid, zinc and phosphorous solubilization, capacity to promote tomato seedlings growth (pot experiments). Cladosporium isolate T2 presented positive results to all tests. Encouraging results were obtained treating tomato seedlings with PHs from isolate Cladosporium T2 cultured on medium supplemented with 1% (w/w) chicken feathers, for which growth parameters, such as stem weight, stem height, and root weight were significantly higher by 65%, 32%, and 55%, respectively, compared to those treated with water.

The experiment was carried out in agricultural land in Sorman between 4 - 2017 to 7 - 2017, in the design of Randomized Complete Block Design (RCBD) to study the response of vegetative traits and chemical properties in the tomato plant of Tariz for organic fertilization, by 6 treatments and 3 replicates, For SPSS statistical analysis at a significant level of LSD 0.05). The experiment included four types of semi-decomposed organic fertilizer (sheep manure, cattle manure, camel manure, horse manure) in 6 treatments, in addition to the control treatment, which included four treatments for each type of organic fertilizer as: fertilizer: soil by ratio (1: 3) that is 5Kg of fertilizer : 15 kg of soil, mixed treatment of fertilizer : soil (1: 1) (10 kg of fertilizer: 10 kg of soil), and double treatment (3: 1) (15 kg of fertilizer: 5 kg soil). The seedlings were planted in experimental units of 7.20 m2. The seedlings were treated in biological control using the garlic extract for insect protection after 15 days of planting, as well as the addition of simple proportions of hay as a cover to reduce the growth of herbs. The experiment showed that the treatment of cattle manure significantly increased most of the studied morphological traits (length of root, plant length, number of flowers, number of leafy branches), as well as significant increase in fresh and dry weight of leaves and average weight of five fruits.. There were significant differences in the content of the N, P in leaves and NPK elements in the fruits, while there was a significant increase in vitamin C content in fruits for all treatments.

Seeds of two hybrid spruce (Picea glauca (Moench) Voss × Picea engelmannii Parry ex Engelm.) ecotypes were inoculated with one of six plant growth-promoting rhizobacteria (PGPR) strains previously shown to be able to stimulate spruce growth in controlled environments. The resulting seedlings were grown in the greenhouse for 17 weeks before outplanting at four reforestation sites. Inoculation with five of the six strains caused significant seedling growth promotion in the greenhouse, which necessitated analysis of relative growth rates (RGR) to evaluate seedling performance in the field. Four months after outplanting, most strains enhanced spruce shoot or root RGRs in the field, but seedling growth responses were strain specific. For example, Pseudomonas strain Ss2-RN significantly increased both shoot and root RGRs by 10-234% at all sites, but increases of 28-70% were most common. In contrast, Bacillus strain S20-R was ineffective at all outplanting sites. In addition, seedlings inoculated with four of the six strains had significantly less shoot injury than control seedlings at all sites. Evaluation of root colonization by PGPR indicated that bacterial population declines were not related to spruce growth response variability in the field. Our results indicate that once plant growth promotion is induced in the greenhouse, seedling RGR can increase by more than 100% during the first growing season in the field. However RGR increases of 21-47% were more common and may be more representative of the magnitude of biomass increases that can result from PGPR inoculation.

Abstract. Rahma H, Nurbailis, Kristina N. 2019. Characterization and potential of plant growth-promoting rhizobacteria on rice seedling growth and the effect on Xanthomonas oryzae pv. oryzae. Biodiversitas 20: 3654-3661. Xanthomonas oryzae pv. oryzae (Xoo), a major limiting factor in rice production, and the use of resistant Xoo varieties have failed to control the bacterial pathogens as well as increased yield. It is due to the diversity in pathotypes, caused by environmental factors, the nature of resistant variety used, and gene mutation. The aims of this study were to select rhizobacterial strains with the potential of suppressing Xoo growth and promoting the growth of rice seedlings. This experiment was conducted in a completely randomized design (CRD) using seven rhizobacterial isolates selected through a dual culture test, with four replications. There were four isolates that potential in inhibiting the growth of Xoo, namely KJKB5.4, LMTSA5.4, Bacillus cereus AJ34, and Alcaligenes faecalis AJ14, with inhibition diameters greater than 11.50 mm. Rhizobacterial supernatant of 4 potential isolates has a zone of inhibition ranging from 12.25 to 24.00 mm. Four potential isolates were also able to solubilize phosphate, produce indole acetic acid (IAA) growth hormone, and siderophore, as well as enhance the growth of rice seedlings. Based on the nucleic acid sequencing of LMTSA5.4, KJKB5.4, and RK12 isolates were identified as Stenotrophomonas malthopilia strain LMG 958 (99.13%) accession NR 119220.1, Stenotrophomonas pavanii strain LMG 25348 (95.84%) accession NR 118008.1 and Ochrobactrum ciceri strain ca-34 (92.91%) accession NR115819.1.
