In the present study, the seaweeds belong to Phaeophyaceae (Halopteris scoparia (Linnaeus) Sauvageau 1904, Cystoseria mediterranea Sauvageau 1912), Rhodophaceae (Liagora viscida (Forsskål) C.Agardh 1822, Laurencia nidifica J.Agardh 1852) and Chlorophyceae (Enteromorpha multiramosa Bliding, nom. inval. 1960) collected from nearby Iskenderun-Turkey of Mediterranean Sea were detected for their antimicrobial activities against seven bacterial (Escherichia coli ATCC 35218, Bacillus cereus NRRL B-371, Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae ATCC 13883, Salmonella typhimurium ATCC 14028, Proteus vulgaris RSKK 96029) and three fungal strains (Candida albicans ATCC 10231, C. krusei ATCC 6258, C. tropicalis Y-12968). The antimicrobial activities were expressed as minimum inhibitory concentrations (MICs), minimum bacterial concentrations (MBCs) and minimum fungicidal concentrations (MFCs) were determined. According to the results obtained from MIC values of the extracts on pathogenic microorganisms were between 50 and 50 and

Kuru baza göre başlangıç nemi %83,95 ± 0,01 y.b. (5,24 ± 0,003 kg su kg KM-1) olan 100 ± 0,10 g ağırlığındaki Deveci armudu dilimleri (Pyrus communis L. cv. Deveci) son nemi %11,40 ± 0,06 y.b. (0,13 ± 0,001 kg su kg KM-1) değerine ulaşıncaya dek gölgede kurutma, 60, 80 ve 100°C’de sıcak havayla kurutma yöntemleriyle kurutulmuş ve bu yöntemlerin kurutma süreçleri sırasıyla 11150, 437, 252 ve 148 dakikada tamamlanmıştır. Çalışmada deneysel olarak elde edilen zamana bağlı ayrılabilir nem oranı değerleri yirmi farklı ince tabaka kurutma eşitliği kullanılarak modellenmiştir. Buna göre 60°C ve 100°C için deneysel verilere en yakın sonuçları veren modelin Modified Henderson & Pabis eşitliği olduğu; buna karşın gölgede kurutma ve 80°C’de kurutma yöntemlerinde ise sırasıyla Alibas eşitliğinin ve Jena & Das eşitliğinin en iyi modeller olduğu görülmüştür. Gölgede kurutma yönteminde her hangi bir enerji tüketimi olmamasına karşın bu yöntemin oldukça uzun olması ve ürünün kalite parametreleri üzerinde olumsuz etkilere yol açması gibi nedenler Deveci armudunun kurutulmasında gölgede kurutma yönteminin kullanışlı bir yöntem olmadığını ortaya koymuştur. Bununla birlikte toplam enerji tüketiminin kurutma sıcaklığının artmasıyla yükseldiği görülmüştür. Ayrıca sıcaklık artışının kalite parametrelerini de olumsuz etkilediği tespit edilmiştir. Kurutma süresi ve özgül enerji tüketimi gibi işletim parametrelerinin yanı sıra parlaklık, kırmızılık, sarılık, kroma, hue açısı, toplam renk değişimi ve kahverengileşme indeksi gibi kalite parametrelerinin taze ürüne oldukça yakın olmasından dolayı 60°C’de sıcak havayla kurutma yönteminin Deveci armudunun kurutulması için uygun bir yöntem olduğu görülmüştür.

Son yıllarda, ekoturizm gelişimi için uygun alanları belirlemeye yönelik çalışmalarda Coğrafi Bilgi Sistemleri (CBS) teknolojisinin yaygın olarak kullanıldığı görülmektedir. CBS teknolojisi, sayısallaştırılmış veri kullanarak sistematik ve kapsamlı bir analiz sunan güçlü bir yaklaşımdır. Araştırmacılar topoğrafya, arazi örtüsü, iklim, sosyokültürel yapı vb. bileşenlere sayısal değerler vermek suretiyle yaygın yöntemler oluşturmaya çalışmaktadır. Fakat araştırmaların çoğunun vaka çalışması şeklinde olması, her çalışmada alana özgü değerlemeler yapılması ve bazı niteliklerin sayısal olarak ifade edilme güçlüğü, ortak yöntemler ortaya koymayı zorlaştırmaktadır. Bu araştırmada CBS araçları ile yapılan alan uygunluğu analizlerinin farklı aşamalarında kullanılan çeşitli yöntem ve yaklaşımların sonuçlar üzerindeki etkileri incelenmiştir. Sonuçların CBS’ye eşlik eden Çok Kriterli Karar Verme (ÇKKV) tekniklerine, analizde kullanılan kriterlerin seçimine ve bunlara ağırlık tayin etme yöntemlerine, kriterlerin nasıl standardize edildiğine ve sonuç haritasının yorumlanmasını sağlayan uygunluk analizi türlerine göre değiştiği görülmektedir. Özellikle sosyokültürel bileşenlerin sayısal olarak ifade edilme zorluğu ve çeşitliliği, CBS ile yapılan nicel değerlendirmenin yanında nitel değerlendirmenin de gerekli olduğunu ortaya koymaktadır. Bunun yanısıra ekoturizm uygunluk seviyelerinin belirlenmesinde kullanılan Doğal Kırılmalar Yöntemi, Eşit Aralık Yöntemi ve FAO (Gıda ve Tarım Örgütü) Arazi Sınıflandırması, analiz haritasında farklı desenler oluşturmaktadır. Sonuç olarak CBS teknolojisi, bu alanda ortak ve yaygın yöntemler oluşturmak için tek başına yeterli değildir ve çalışma alanı ile planlanan faaliyete özgü değerlendirmelerle desteklenmesi gerekmektedir.

One of the most important factors that increase soil fertility is the amount of soil organic matter. One of the ways to increase soil organic matter is the addition of organic fertilizers. Yemsoy soybean cultivar was used in the study, and pot study was carried out in 3 replications according to the randomized blocks experimental design. In the study, three different fertilizer doses (EC 0- 0.5- 1), three different grape pomace compost (0- 20-40 %) were applied to the peat perlite mixture, and mycorrhiza and bacteria inoculation to these environments. At the end of a 60-day growing period, the plants were harvested from the top of the pot, and measurements were made. In the study, there was an increase in the above-ground fresh and dry weights, root fresh, and root dry weights of soybean plants grown with increasing fertilizer rates. The addition of compost to the growing medium, the addition of mycorrhiza, and bacteria caused different results in the investigated properties. The increase in compost and plant nutrition doses was effective in increasing plant growth.

Pseudomonas syringae pv. tomato, the bacterial agent for tomato speck disease, can cause serious epidemics with high leaf moisture, mild temperatures, and cultural practices allowing bacterial dissemination among host plants. Boron is an essential micro-nutrient for plant growth and health in agricultural production. In this study, the effectiveness of 14 different Boron compounds at 5 different doses (1, 5, 10, 20 and 40 mM) against P. s. pv. tomato at a concentration of 108 CFU ml-1 in vitro was evaluated and the most successful 4 different Boron compounds (Ammonium tetrafluoroborate, Sodium tetrafluoroborate, Zinc borate and Disodium octaborate tetrahydrate) were coated with 5 mM doses infected cv. H2274 tomato seeds to determine bacterial populations and seed emergence rates in the seeds. Among the 14 different Boron compounds used in the experiments, Disodium octaborate tetrahydrate was the most successful active ingredient 92% ratio in inhibiting P. s. pv. tomato populations in tomato seeds, while 39% success was achieved with sodium tetrafluoroborate applications. According to the results of the research, it is thought that some Boron compounds can be an economical, effective and environmentally friendly chemical in reducing P. s. pv. tomato in tomato seeds within the scope of good agricultural practices.

In this study, in which the effects of different applications of vermicompost on the yield and quality of San Andreas strawberry variety were investigated 15, 30, 45, 60 g vermicompost was applied per plant. First flowering, first and last harvest dates, number of fruits per plant, yield per plant (g/plant), fruit weight (g), fruit flavor, macro and micro nutrient content, organic acid amounts were examined. The results showed that the differences between treatments in yield per plant were statistically significant. The highest total yield per plant was obtained from V45 and V30 applications with 972.8 g and 878.9 g respectively and the lowest yield was obtained from the control application with 384.2 g per plant. The largest fruits were obtained from the V60 (19.5 g) application. It was determined that nitrogen, phosphorus, potassium, magnesium, sulfur, manganese, iron, zinc and boron concentrations in the leaves of strawberry plants fertilized with vermicompost were higher than the control. The highest values in organic acid values were determined in oxalic, propionic, malonic, lactic, fumaric and succinic acids in V60 application (5.62, 11.16, 49.00, 104.98 µg/100 g respectively). It seems that the application of vermicompost fertilizer in strawberry cultivation has a positive effect on yield and quality characteristics.

Irrigation scheduling is important for efficient use of applied water and for maximizing crop yields. Therefore, the aim of this study was to evaluate the short-term effect of drip irrigation frequency on soil hydro-physical properties of an Alfisol and performance of two maize varieties, at the Teaching and Research Farm, Faculty of Agricultural Sciences, Ekiti State University, Ado Ekiti, Southwest Nigeria. The experiment was laid out using a split-plot experiment in randomized complete block design (RCBD) and three replications. Irrigation frequency constituted the main plot namely: irrigation four times a week (I4), irrigation thrice a week (I3), and irrigation twice a week (I2) of re-filling soil to field capacity while the subplot was maize variety namely: V1: SAMMAZ-27 and V2: OBA-super-6. Plant growth parameters and soil physical properties of soil water content (SWC), bulk density (BD) and saturated hydraulic conductivity (Ksat) were monitored during the growing cycle. Water use efficiency (WUE) and yield components were determined at maturity. There were significant interactions between irrigation regime and maize variety on SWC and Ksat. The maximum bulk density (BDmax) and optimum soil water content SWCopt were 1.41 g/cm3 and 0.12 g/g, respectively. Plant height (PH) did not differ between the two maize varieties throughout the growth cycle. Drip irrigation frequency did not significantly affect plant height until growth stage V12 (12 fully opened leaves), with I4 irrigation treatment having the tallest plant. Both drip irrigation and maize variety had no significant influence on both LAI and CC, neither was there any significant interaction effect. Increasing irrigation water increased maize yield and yield components. The treatment combination of I4V1 had the highest performance indices in terms of yield components. WUE decreased with increasing frequency of irrigation water application while the WUE of SAMMAZ-27 > OBA-super-6. Therefore, irrigating four times a week and SAMAZ-27 maize variety could be a suitable irrigation-variety combination for providing sustainable irrigation agriculture for maize in this region.

The aim of this study was to investigate the effects of organic copper supplementation (0, 5, 10 and 20 mg/kg) in the commercial diet on performance, egg quality and haematological parameters in laying quails. In this 10-week trial, a total of 80 laying quails, aged 22 weeks, were randomly distributed among four experimental groups. Each experimental group contained four replicates of five female birds each. The addition of organic copper to the diets did not statistically affect egg production, egg weight, egg mass, feed conversion ratio, damaged eggs, egg shape index, Haugh unit, and blood parameters except neutrophils and mean corpuscular haemoglobin. Compared to other groups, body weight change was decreased by the addition of 20 mg/kg organic copper, and feed intake was decreased by the addition of 10 mg/kg copper in the quails. The addition of 20 mg/kg of organic copper to the quail diets significantly decreased the eggshell breaking strength and eggshell weight, while it significantly increased the eggshell thickness compared with the control group. The neutrophil and mean corpuscular haemoglobin were increased by the addition of 10 and 20 mg/kg organic copper, respectively, with compare to other groups. It can be said that up to 10 mg / kg of organic copper can be added to commercial quail diets, but its addition at 20 mg/kg negatively effects on some blood parameters as neutrophil and mean corpuscular haemoglobin in quails.
