The Maximum Length Record of the Blackspot Seabream (Pagellus bogaraveo Brünnich, 1768) for the Entire Aegean Sea and Turkish Territorial Waters Full text
2020
Şenol Paruğ | Özgür Cengiz
The maximum length, weight, and age information of organisms in an ecosystem, moreover, the first records of migrated exotic species are essential in terms of the basis for the studies on population dynamics, stock assessment, and biological activities. Therefore, the recording of such data may be necessary for scientific databases and new related studies. The Blackspot seabream (Red seabream - Pagellus bogaraveo), which belongs to the Sparidae family, is an important seafood which is marketed fresh and frozen around the Mediterranean and the Aegean seas. Nowadays, this species has high prices depending on market demands in domestic markets as a result of overfishing and is also cultured in northern Spain. It is classified as “Near Threatened Species” in the red list due to its decreasing population trend by the IUCN. A single specimen of the Blackspot seabream with 30.7 cm in total length and 390.00 g in total weight, which was angled in the Saros Bay with a handline by a fisherman on February 08, 2019, was obtained from a fishmonger in Çanakkale. Even though there are bigger individuals in the North-east Atlantic probably depending on polar and/or deep-sea gigantism, the mentioned measurement is the proven maximum total length of this species for the Aegean Sea up to the time.

Kenzemed Kassie Yassin | Kibebew Kibret | Tadele Amare
Biochar as agricultural soil amendment to improve soil physico-chemical properties, crop productivity and sustainable soil fertility management is a well-known practice. A field experiment was conducted to evaluate the effect of biochar on growth and yield components of carrot and selected soil physic-chemical properties. The study was carried by employing a randomized complete block design with factorial arrangement of four level of biochar (0, 4, 8 and 12 tons ha-1) and four level of Nitrogen/Phosphorus (N/P) fertilizer rate (0/0, 60/10, 90/15 and 120/20 kg ha-1) with four replications. Biochar significantly influenced physico-chemical properties of soils, such as bulk density, total porosity, pH, EC, SOC, TN, Av. P and CEC respectively, as compared to control. The results revealed substantial responses to biochar and N/P fertilization on growth and yield components of carrot with increasing level of biochar and N/P fertilizer rate. None of the others yield parameters were significantly affected by the interaction of two factors. From the present study, it can be concluded that dung cake biochar should be applied to enhance and improve soil physical and chemical properties for favourable plant growth.

Main goals of the present study were (1) to initially investigate the nutrient contents and bioactive compounds in the bulb and cloves of garlic, and (2) to study the growth parameter after planting. Garlic bulbs were firstly separated into three categories as pickled, big and small, while the big garlic cloves were also classified into three categories as big, small and central. Secondly, the garlic samples were analyzed before planting for their element profile, proline, soluble protein, free amino acid, β-carotene, lycopene, total phenolic, soluble sugars, SOD and α-amylase activities. Finally, the growth parameters were measured using the cultivated cloves and the pickled bulbs. According to the result, the highest soluble protein, N, phenolic, lycopene and α amylase activity (97.06 mg, 2.58%, 971 mg, 0.368 mg and 38.13 EU, respectively) were recorded in the biggest cloves. The highest proline, amino acid, glucose content (93.84 µmol, 23.54 mg, 230.89 mg, respectively) and K, P, S, Mg, Mn, Fe and Zn (21940 ppm, 7577 ppm, 12200 ppm, 504 ppm, 38.1ppm, 377,7ppm and 44.5 ppm, respectively) were found in the pickled bulb. The maximum level of β-carotene (0.282 mg), Ca, Cl and Sr (11260ppm, 818.7ppm and 47.9 ppm) were determined in the small bulbs. Based on the growth parameters of seedlings, the highest value of shoot and root length (39.12 cm and 24.11 cm respectively), the fresh weight of shoot and root (5.29 g and 4.54 g respectively) and dry weight of shoot and root (1.70 g and 1.24 g respectively) were noted with the big cloves. The results of the current study have indicated that the pickled cloves have higher macro and micro nutrients, proline, amino acid and glucose, while the big cloves of garlic have higher proline, phenolic, N%, lycopene and amylase activity. It can be said that the big cloves showed good value for the five bioactive compounds, but the pickled exhibited good value for the macro and micro element and glucose.

In this study, performance characteristics such as power take off (PTO) power consumption, fuel consumption, fuel consumption for the unit field-unit product were determined at different working speeds with two different PTO applications (540 and 540E) in a single row disc type silage machine. In particular, the 540E PTO application greatly reduces fuel consumption for unit work. The best results in terms of hourly fuel consumption were achieved in 540E PTO application and V1 working speed. When the field - product fuel consumption is evaluated, the best results were obtained with the 540E PTO application at the V3 working speed. When an evaluation is made considering all the parameters, it is concluded that the 540E PTO application will provide certain advantages in terms of fuel consumption compared to the 540 PTO application for the silage machine operating by taking the motion from PTO. 540E PTO application can be used as an important alternative to 540 PTO application for machines of similar capacity and features.

In this study, optimum harvest times, cluster and berry characteristics of four grape cultivars (Hasandede, Öküzgözü, Boğazkere, and HorozKarası) grown in Mecitözü (Çorum) ecological conditions were determined. In two consecutive years (2017-2018) yield, clusters, berry properties, water-soluble solid content, pH, titratable acidity, maturity index properties were determined. Some biochemical changes in grape varieties were followed during the ripening periods in the second year. The highest yield in both years was obtained from the variety of Horoz Karası (1421.2 and 1504.8 kg/da), while the lowest yield was obtained from Öküzgözü (619.4 and 578.31 kg/da). During the harvest period, the total acidity and pH values must be changed according to years and varieties. The total soluble solids (TSS) and pH values increased with maturation, whereas the total acidity was found to decrease till the last observation date. During the harvest period, all varieties reached optimum harvest maturity in both years.

The increasing scarcity and competition for irrigation water entails adoption of innovative practices that increase efficient water use. The objective of this research was to compare different mulching techniques and investigated the combined effect of irrigation levels under drip irrigation system based on the parametric evaluation system in western part of Ethiopia during the 2018 dry season. A factorial combination of five levels of water (namely 100%, 80% and 70%, 60% and 50%ETc) combined with three mulch treatments (namely, Normal Mulch (NM), Straw Mulch (SM) and Plastic Mulch (PM)) with three replications. The analysis of variance showed that, days to 50% maturity, leaf number per plant, mean leaf length, plant height and leaf area were significantly affected by the main effects of deficit irrigation levels and mulching materials. The interaction effects of deficit irrigation levels and mulching materials significantly influenced plant height, number of leaf per plant, plant height, Leaf length and Leaf area of the onion. The present study suggests that, in water scarce area, farmers are advised to adopt deficit irrigation level with 80% ETc under plastic mulch. It is important even to undertake similar studies at different seasons with different varieties in consideration of their cost benefit analysis. However, if water is not a limiting factor, farmers are advised to apply full irrigation water application under plastic mulch.
