The objectives of this study were to define direct and indirect correlations between the factors and the yield of four chickpea (Cicer arietinum L.) genotypes and to assess their effectiveness proportions in the Acological conditions of Erzurum by path analysis. The experiment was conducted on arid lands of Erzurum and Aziziye-94, Ipik, Cagatay and Yasa genotypes were used in this two-year experiment. Path analysis indicated the highest direct and positive effect of pod number (1.095), first pod height (0.574), and 100- seed weight (0.254) on seed yield. On the other hand, it indicated the direct and negative effect of plant length (-0.341), branch number (-0.383), seed number/pod (-1.311) on seed yield.

A survey was conducted in 8 counties of Erzurum city with 165 farmers to determine the factors effective on hygiene and health management in stock breeding enterprises. The LIMPED software package was used to analyze the survey data using Logit Model. Four factors which are needed to consider for improving the hygiene and health conditions in stock breeding enterprises were used as dependent variables. These factors were as follows: routine health checks of the animals in the farm; cleansing hands and machine parts before milking; elaborating in the care and hygiene conditions of the animals in the farm and daily cleaning of the barn. It was concluded that age, education level and income of the farmer, regional differences, participation to agricultural extension training activities following agriculture-related broadcasts from mass media and the total number of culture race animals owned by the farm were effective on considering the hygiene and health management in stock breeding enterprises. In this context, it is necessary that the number of culture race animals should be increased; farmers should be trained on hygiene and health issues periodically and regularly with the help of mass media means and that farmers should be encouraged to make market based production so that their income could be increased. © Medwell Journals, 2011.

The essential oils of aerial parts of Achillea gypsicola Hub.-Mor., Hypericum scabrum L., Satureja hortensis L., and Origanum acutidens (Hand.-Mazz.) Letswaart were analyzed in this study by GC and GC-MS and their oils were tested for toxicity against broadbean weevil (Bruchus dentipes). A. gypsicola oil contained camphor (40.17%), 1,8-cineole (22.01%), piperitone (11.29%), borneol (9.50%) and α-terpineol (1.56%) as major components. A total of 74 components were identified by GC-MS in H. scabrum oil, including α-pinene (9.26%), terpinen-4-ol (5.12%), camphor (5.94%), δ-cadinene (4.52%), pulegone (4.45%), γ-muurolene (4.12%), pinocarvone (3.97%) and β-caryophyllene (3.42%) as predominant components. The essential oils of O. acutidens and S. hortensis were characterized by high contents of carvacrol (86.99% and 55.74%), γ-terpinene (0.71% and 20.94%), p-cymene (1.95% and 12.30%), α-terpinene (0.13% and 2.04%) and β-caryophyllene (1.30% and 1.08%). All of the essential oils were toxic to adults of B. dentipes and insect mortality increased with increasing concentration of each oil. The oils (20 μl dose) brought about 100% mortality in 36. h. Although desirable insecticidal activities against the pest were achieved with the oils from all four plant species, S. hortensis and O. acutidens oils were more effective, particularly after 6. h of treatment. The current results concluded that the essential oils, in particular O. acutidens and S. hortensis oils, may be used as potential botanical insecticides against B. dentipes. © 2011 Elsevier B.V.

Essential oil isolated from the aerial parts of Nepeta meyeri Benth. by hydrodistilation was analysed by GC and GC-MS methods. A total 18 components were identified in the oil representing 100.0% of the oil. Main components were 4aα,7α,7aβ-nepetalactone (80.3%), 4aα,7α,7aβ-nepetalactone (10.3%), trans-pulegol (3.1%), 1, 8-cineole (3.0%) and β-bourbonene (2.0%). In addition, n-hexane extract of N. meyeri was analysed by using GC and GC-MS methods and 18 components were identified. Likewise, nepetalactones, 4aα,7α,7aβ7a-nepetalactone (83.7%), 4aα,7α,7aβ-nepetalactone (3.6%), 1, 8-cineole (1.9%) and α-terpinene (1.5%) were the predominat compounds in the hexane extract. Three concentrations (0.5, 1.0 and 2.0 mg/mL) of the essential oil and n-hexane, chloroform, acetone and methanol extracts isolated from the aerial partsand roots were tested for the herbicidal effects on the germination of the seeds of four weed species including Amaranthus retroflexus L., Chenopodium album L., Cirsium arvense L. and Sinapsis arvensis L. The essential oil of N. meyeri completely inhibited the germination of all weed seeds whereas the extracts showed various inhibition effects on the germination of the weed species. Herbicidal effect was increased with the increasing application concentrations of the extracts. In general, the acetone extract was found to be more effective as compared to the other extracts. All extracts also exhibited various inhibition effects on the seedling growths of the weed species. All extracts also tested for their phytotoxic effects on the weeds at greenhouse condition and the results showed that the oil and extracts caused mortality with 22.00-66.00% 48h after the treatments. These findings suggest that the essential oil and the extracts of N. meyeri have potentials for use as herbicides against those weed species. © 2015 ACG Publications. All rights reserved.

Powdery mildew symptoms were observed on the leaves of horse chestnut (Aesculus hippocastanum) which is common in urban areas of Ordu province, Turkey. The pathogen was identified as Erysiphe flexuosa based on morphological characters. This is the first report of E. flexuosa on horse chestnut from Turkey. © Australasian Plant Pathology ociety 2010.
