The aim of this study was to investigate the effects of solid and liquid vermicompost on yield and nutrient uptake of tomato plant. The study was carried out with three replications according to the experimental pattern of randomized plots in the plastic pots with the capacity of 3 kg under the greenhouse conditions of Plant and Animal Production Department of Cumhuriyet University. In the study, chemical fertilization was applied for comparison with solid and liquid vermicompost. Vermicompost doses were applied as 0%, 10%, 20%, 30% and 40%. In the study, tomato yield and nitrogen (N), phosphorus (P), potassium (K), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) concentrations were determined. The results have shown that 10% solid vermicompost increased dry matter production of tomato plant with 8,92 g pot-1. This application was followed with 7,04 g pot-1 dry matter production in 20% solid vermicompost application. The highest increase in P (0,27% P) and K (9,01%) concentration of tomato plant was determined in 40% solid vermicompost. However, the highest N concentration was determined with chemical fertilization (4,06%). Generally, it was determined that the solid vermicompost higher effect on the yield and nutrient uptake of tomato plant than liquid vermicompost.

The aim of this study was to evaluate the chemical composition and mineral bioavailability of T. tetraptera fruit pulp, an aromatic wild edible plant, using standard methods. The pulp were extracted from mature dried fruits obtained from plants at Awabo (5°30’14.2”N and 4°01’30.6”W) and Loviguié villages (5°48’24.5’’N and 4°20’15.8”W), all in south-eastern Côte d’Ivoire. The results of chemical analysis revealed that T. tetraptera fruit pulp contains carbohydrates (63.73±0.51%), crude protein (7.01±0.66%), crude fat (1.18±0.01%), ash (5.38±0.18%), fibre (11.78±0.02%), moisture (40.52±0.18%) and an energy value of 254.74±0.15 kcal/100g. Besides, the results showed a relative high amount of vitamin A (2.11±0.02%) and vitamin B9 (261.78±0.01 µg/100g) while vitamin E, B1 and B2 in trace concentration. Otherwise, the phytochemical analysis (mg/100g) based on dry weight revealed an appreciable amount of total phenol (2407.10±8.36), flavonoids (14.29±0.56), tannins (55.11±0.44), catechin (392.93±1.01) and also carotenoids (108.19±7.42 µg/100g). Organic acids profile (mg/100mL) showed citric acid (175.06±0.02) and salicylic acid (109.85±0.01) as major organic acids. Mineral composition (mg/100g) on dry weight basis revealed that potassium (1303.67±0.58) is the most abundant followed by phosphorus (303.33±5.77), calcium (187.33±0.58) and magnesium (141.33±0.57). Furthermore, the Phytates:Zn, Phytates:Ca, Oxalates:Ca and Phytates*Ca:Zn molar ratios recorded were all below than recommended threshold values, implying a bioavailability of zinc and calcium. These data indicate that the pulp of this fruit could be a good source of ingredient for both medicine and food industries in production.

Yenilenebilir enerji kaynaklarına olan yönelme son yıllarda giderek artmaktadır. Bu yöneliş, öncelikle potansiyel hesaplamalarıyla başlamış, zamanla teknolojilerin uygulamasına geçilmiştir. Teknolojik anlamda güneş enerjisi uygulamaları; genelde ısıtma, elektrik üretme ve tarımsal sulama amaçlı olmaktadır. Elektrik üretmede fotovoltaik pil (PV) uygulamaları, dünya çapında büyük ivme kazanmıştır. Fotovoltaik sulama sistemlerinde boyut analizi yapılırken, kullanılan eski metotlar, sadece üretilen hidrolik enerjinin gereksinimlerini dikkate alırdı. Bu metotların aksine bu çalışmada problem, sistematik olarak ele alınıp, sistemin bütün elemanlarının ve bileşenlerinin analizleri yapılmıştır. Bu çalışmada, öncelikle Niğde’nin tarımsal yapısına uygun olarak, patates üretimi yapılan işletmenin enerji ihtiyacı belirlenmiştir. Söz konusu çalışmalar göstermiştir ki; tarımsal amaçlı sulamada, çok büyük bir enerji ihtiyacı bulunmaktadır. Bu enerji ihtiyacının güneş enerjisi ile karşılanmasının ekonomik boyutu sistemin projelendirilmesi, uygulanması ve üretilen elektriğin değerlendirilmesine göre çok değişkenlik göstermektedir. Çalışmada, bu sorunlar uygulama ve farklı senaryolar dahilinde irdelenmiştir.

In this study, the antioxidant activities and biochemical characteristics of Ulva rigida (Ulvophyceae) and Arthrospira platensis (Cyanophyceae) were determined. The extracts from two seaweed species were evaluated for their free radical scavenging activity, using the 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH) method, their total phenolic, flavonoid, and condensed tannin contents, through Folin–Ciocalteu, Quettier-Deleu, and Price methods, respectively. The extracts of two seaweeds showed a low free radical scavenging capacity in comparison with commercial antioxidant BHT (butylated hydroxytoluene), and vitamin C. The extract of U. rigida demonstrated greater antioxidant potential with a low IC50 (3.76±0.02 mg/g Ext.). The total phenolic contents were ranged from 2.21±0.08 (U. rigida) to 8.59±0.62 (A. platensis) mg GAE/g of extract. The highest flavonoid content was found in A. platensis as 22.70±0.65 mg rutin/g of extract. The contents of condensed tannin were measured 3.01±0.11 mg CE/g of extract for A. platensis and 3.76±0.06 mg CE/g of extract for U. rigida. According to results obtained, U. rigida and A. maxima possess antioxidant activity and could be used in for future applications in medicine, functional foods, and agriculture.

In this study, seasonal changes in the lipid and fatty acid profiles of S. lessepsianus caught from the Mersin Bay were investigated. The total lipid levels of S. lessepsianus were found to be 2.94%, 7.19%, 2.45%, 0.83%, in spring, summer, autumn and winter season, respectively. Major fatty acids in S. lessepsianus were palmitic acid, stearic acid, oleic acid, palmitoleic acid, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in all seasons. The highest values of palmitic, palmitoleic and EPA were determined as 22.97%, 3.80% and 4.22% in spring, respectively. The highest values of stearic and oleic acid were determined as 15.93% and 7.84% in autumn, respectively. The highest value of DHA were also determined as 31.91% in winter season. The EPA level from polyunsaturated fatty acids was found in the range of 2.54-4.22% (23.09-195.62 mg/100g). The highest level of DHA were observed in the winter season and its levels changed in the range of 19.83-31.81% and was calculated as 201.29-1301.73 mg/100g. In addition, the highest level of the Σn3, Σn6, and Σn9 were calculated in the summer season as 1516.39, 114.88, 399.77 mg/100g, respectively. This report showed that fat and fatty acid profiles of S. lessepsianus are quite influenced by seasonal factors.

Doğadan toplanan erkek ve dişi kurbağaların (Pelophylax ridibundus), boy uzunluğu (SVL) ve arka bacak uzunluğu ile karkas, arka bacak, deri, baş ve karaciğer ağırlığı alınarak karkas miktarı belirlenmeye çalışılmıştır. Dişi kurbağaların ortalama SVL değeri 91,6±0,53 mm, erkeklerin 81,1±0,69 mm olarak ölçülerek, aradaki farkın istatiksel açıdan önemli olduğu tespit edilmiştir. Gıda olarak tüketilen arka bacakların ortalama uzunluk değerleri, dişi kurbağalarda 72,0±0,65 mm, erkek kurbağalarda 68,0±0,53 mm tespit edilmiş ve aradaki farkın istatiksel açıdan önemli olduğu görülmemiştir. Arka bacakların ortalama ağırlıkları dişi kurbağalarda 21,45±5,06 g, erkek kurbağalarda 15,53±2.94 g olduğu ve her iki cinsiyette de bu miktarların toplam vücut ağırlığının yaklaşık %25’ine denk geldiği belirlenmiştir. Çalışma esnasında dişi kurbağaların sırasıyla vücut, karkas ve gıda olarak tüketilen arka bacaklarının ortalama ağırlıkları, erkek kurbağalara göre daha yüksek miktarda tespit edilmiş olup; dişi kurbağalar ile erkek kurbağalar arasındaki bu ağırlık farkları aynı zamanda istatistiksel açıdan önemli bulunmuştur. Karkas ağırlıkları, hem dişi hem de erkek bireylerde toplam ağırlığın yaklaşık olarak %50’sini oluşturmaktadır. Kesim işlemi sonucunda karkas dışında kalan; deri, baş ve karaciğerin ortalama ağırlıkları dişi kurbağalarda erkek kurbağalara oranla daha fazla miktarda bulunmuştur. Dişi ve erkek bireyler arasında baş ağırlığı hariç karkas dışında kalan diğer kısımlar arasındaki farkların önemli olduğu belirlenmiştir. Kurbağa derisi önemli bir sanayi ürünü olup, miktarı dişi kurbağalarda ortalama 8,07±2,04 g, erkek kurbağalarda ortalama 5,66±1,21 g bulunmuştur. Bu değerlerin oranı, toplam vücut ağırlığının %10’una denk geldiği tespit edilmiştir. Bu çalışmada, dişi kurbağaların erkek kurbağalardan karkas kazancı bakımından daha iyi olduğu ve karkas miktarı dışında kalan, baş, karaciğer ve derinin miktarı tespit edilerek değerlendirilmesi araştırılmıştır.
