In this study, the effects of four different color plastic greenhouse treatments on nutrient concentrations of leaf and fruit, leaf SPAD (Soil and Plant Analyzer Development) values and some yield parameters of tomato were tried to be determined. For this purpose, plastic greenhouses with Red (RedG), Blue (BlueG), Colorless (ConG) and white Led (LedG) lighting have been used as materials in the research. The used plastic greenhouses are 3 m in width, 6 m in length, 2 m in sidewall height and 2.8 m in roof ridge height. Led lighting is; Three hours of extra lighting is planned for one hour before sunrise, 2 hours after sunset. The research was carried out in ISUBU (Isparta), Faculty of Agriculture, field area in the summer season in 2019. The nutrient elements of K, Ca, Mg, P, Cu, Zn, Mn and Fe were determined in the leaf and of the tomato plant. It has been determined that four different greenhouse treatments have a positive effect on K, Ca, Cu, Zn, Fe nutrients in leaf, and K, Ca, P, Mg nutrient in fruit. In terms of SPAD values, all treatments were determined to be higher than the control treatment. It was determined that the highest SPAD value was in BlueG treatment. When the efficiency-related values are examined; It was determined that the highest fruit number, fruit weight and yield were in BlueG treatment. BlueG treatment was followed by RedG, ConG, and LedG treatment respectively in terms of efficiency. As a result, considering the effects of four different greenhouse treatments on macro and micronutrient nutritions SPAD values, and yield values, it was concluded that the most suitable treatments for tomato cultivation in greenhouses is BlueG treatment and RedG treatment should not be ignored.

In this study, it was aimed to investigate the arterial vascularization of the kidneys in the South Karaman sheep breed. Twelve South Karaman sheep kidneys were used in the study. The course of the renal arteries in the kidney was examined by means of dissection and corrosion cast techniques. The kidneys were vascularized with right renal artery and left renal artery to the arteries originating from the abdominal aorta. Right renal artery was seen to be slightly more prominent than the left renal artery. Left renal artery was measured longer and thicker than the right renal artery. The renal artery entering the renal hilus, dorsal and ventral part of the renal artery were detected. However, in several materials, the left renal artery was shown to have a third branch. The dorsal and ventral branches gave interlobar artery with numbers ranging from 2-5. Each interlobar artery had multiple arcuate artery. These arteries ended by giving the interlobular artery. Anastomosis was not observed between the renal arteries. Although there were some important variations in the distribution of renal arteries of South Karaman sheep, similar findings were reported in the literature.

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.

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 22C 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.

Meat and Milk Institution is implementing red meat sales through grocery chains in order to ensure stability in red meat prices in Turkey. In this study in order to evaluate the effectiveness of this policy from the perspective of consumers, data set obtained from 388 households in Gaziantep city center was used. According to the findings, it has been determined that 53.6% of consumers prefer contracted markets due to the suitability of red meat prices. Initially, all consumers bought red meat from contracted markets, but it was found that 62.11% of them gave up buying red meat from these markets. This situation was found to be quite remarkable and logit model was used to determine the factors affecting the continuity of red meat purchase of households from contracted markets. According to the Logit model results, it was observed that households buying red meat from the contracted markets were affected by the variables that they are care about the price of red meat, income and frequency of shopping at these markets. As a result, it can be stated that this policy implemented by the ESK is aimed at selling red meat to low-income consumers rather than providing price stability and does not have a demand increasing effect.

La agricultura ha progresado ininterrumpidamente, pasando de la utilización de recursos naturales gratuitos al uso creciente de recursos fósiles como fuentes energéticas. Si bien la agricultura depende fundamentalmente de los recursos y servicios del ecosistema, su desarrollo se ha centrado sólo en la producción, sin tomar en cuenta el valor ecológico de las externalidades negativas ni la descapitalización de los recursos que inciden en la sustentabilidad, por lo que la información sobre la evaluación de la sustentabilidad de los diferentes estilos de agricultura es poca o casi nula. En la presente investigación se evaluó la sustentabilidad de los estilos de agricultura (horticultor intensivo, tradicional campesino y horticultor auto sostenible) establecidos en la comuna de Hualqui (Región del Biobío, Chile), mediante los flujos de energía presentes en cada estilo, para medir el impacto que generan sobre el paisaje.
