Günümüz dünyasında küresel ısınmanın etkileri görülmeye başlamıştır. Küresel ısınma dünyayı olduğu gibi Türkiye’yi de etkilemektedir. Türkiye’de bölgesel olarak çok çeşitli olarak görülen iklimsel elemanlar illere göre de farklılıklar içermektedir. Bu çalışmada bu tür iklimsel değişiklerin illere göre değerlendirilmesini teminen Ankara, Rize, Aydın, Hakkâri illeri için yağışlarla ilgili olarak 10, 15 ve 20 ve 48 yıllık geleceğe yönelik projeksiyonlar yapılmıştır. İller değişik bölgelerden seçilerek bölgesel farklılıkların da durum değerlendirilmesine konu olması hedeflenmiştir. Analiz sonuçlarına göre ise 1971 ile 2018 yılları arası Ankara ilinde yıllık ortalama yağış 408,59 mm olurken, Rize’de 2262,76 mm, Aydın 634,33 mm ve Hakkâri ili yıllık yağış ortalaması ise 746,93 mm olarak gerçekleşmiştir. 2019-2066 yılları arası için yapılan projeksiyonlarda gerçekleşen verilerle karşılaştırıldığında küresel ısınmaya paralel olarak ortalama yıllık yağışlarda hemen hemen her ilde değişikliklerin olduğu görülmektedir. Ancak bu değişiklikler yağış miktarlarında aşırı değişiklikler anlamına gelmemektedir. Bu manada küresel ısınmanın etkisi yağış miktarlarındaki aşırı artışlar olarak değil, yağışların düzensiz ve baskın şeklinde olması şeklinde görülmektedir. Küresel ısınmanın yol açtığı bu düzensiz ve baskın yağışlar neticesinde tarımsal faaliyetler zarar göreceğinden dolayı gıda güvenliğinin sağlanmasının gerekliliği açısından tedbir alınması konusuna ışık tutması yönüyle bu çalışma önem arz etmektedir.

In this study, the effects of light stimulation at normal (NLS: 154 days) and early (ELS: 140 days) age on some physiological and reproductive traits in dam and sire broiler pure-lines were carried out during the laying period. The study was conducted with A1, A2, A3, A4 dam lines and B1, B2 sire lines up to 43 weeks of age, whose breeding studies were carried out in Eskişehir Geçit Kuşağı Agricultural Research Institute. Live weight and feed consumption were determined during the growing period. In the laying period, in addition to these, the first laying age, 50% yield age, egg yield, hatching egg yield and egg weight were determined. The data obtained were evaluated according to light stimulation age and pure-lines by two factor analysis of variance. NLS and ELS treatments did not significantly affect the body weights of the pure-lines at 20, 24 and 43 weeks of age. However, differences were found significant in terms of body weight at 20, 24 and 43 weeks of age in pure-lines. Lines reached the first laying age at 172 days in NLS, and at 165 days of age in ELS. The 50% yield age was realized at 184 d and 176 d of age in parallel with the first laying age. The effects of light stimulation age on egg yield and hatching egg yield were found significant. In NLS treatment all pure-lines, 5 more eggs were produced in egg yield and hatching egg yield. However, differences in egg yield and weight in pure-lines were found significant. The study results showed that the egg production can be increased by first light stimulation at the 20 weeks of age, provided that at least 2 kg live weight is achieved in broiler pure-lines.

Free glutamic acid is a flavor enhancer compound that provided umami taste. San-sakng (Albertisia papuana Becc.) leaf has been used as a seasoning in the Dayaks tribe, West Kalimantan, Indonesia. The aim of this study was evaluated the effect of different drying inlet air temperature on physico-chemical of the spray dried san-sakng leaf. San-sakng leaf powders was produced using spray drying and maltodextrin as raw material. Completely randomized design was used with one factor, namely drying inlet air temperature on the spray drying process (130°C, 140°C, and 150°C). The results showed that moisture, solubility, bulk density, particle size, and encapsulation efficiency on the San-sakng leaf powders presented significantly affected by the drying inlet air temperature. Increasing inlet air temperature led to reduced moisture, bulk density, and particle size, whereas enhancing the solubility and encapsulation efficiency.

The aim of this study was to examine the effect of five different wavelengths of light on the comfrey plant (Symphytum officinale) (family Boraginaceae). The light source and wavelengths used in the study were UV-A (390-410 nm), blue (465-485 nm), red (620-630 nm) and cool white (CW) daylight (400-700 nm, 6500 K), LED (Light Emitting Diode). In the study, each of the 5 different light applications was applied for 45 days (T1: 100% blue; T2: 100% red; T3: 60% blue + 35% red + 5% UV-A; T4: 100% CW daylight; T5: 80% CW + 20% red). The experiments were carried out under conditions of 22C temperature, 60% humidity, 16/8 hours light/dark and 180 µmol.m-2.s-1 Photosynthetically Active Radiation (PAR). After each application, measurements were taken of number of leaves, number of roots, height of plant, amount of chlorophyll in leaves, leaf colour and brightness. According to data obtained, the different wavelengths of the coloured light applied in the growing environment created a change in colour and brightness of the leaves, height of the plant, length of the roots, and number of leaves and roots.

In order to gain competitive advantage in national and international markets through globalization, make the competition sustainable, produce products with advanced technologies and innovative activities and make a flexible production in line with changing demand make firms and / or sectors advantageous in global competition. This study aimed at analyzing a competitive analysis of fruit sector through the Diamond Model developed by Michael Eugene Porter in order to demonstrate national and sectoral competitiveness. For this purpose, the current situation of fruit sector, which is an important economic activity in Isparta, was put forward and analyzed its competition level was discussed. The necessary data for the Diamond Model were gathered through face-to-face surveys with 47 large fruit producers and in-depth interviews with the representatives of other related sectors. Although the fruit sector and related sectors have been located close to natural resources and inputs in the neighbourhood in Isparta, an ordinary agglomeration has emerged but it could not be clustered because collaboration culture has not been developed in the sector and intersectoral. This fact decreases the regional competition chance of the sector. However, existence of an easy and continuously communication among all actors in the sector, state supports to sectoral cooperation / organizations, and actors who are compulsory for benefiting these supports in the region should be considered important advantages for a clustering and increasing regional competitiveness power of fruit sector.
