Hande Küçükönder | Kazım Kubilay Vursavuş | Fath Üçkardeş
The aim of this study is to determine the factor effective in determining the hardness of Caterina, Suidring, Royal Glory and Tirrenia peach types using meta analysis. In the study, the impact force (Fi) and the contact time (tc) were detected and the impulse values (I) that are expressed as independent variable in the area under the curve were calculated in the measurements performed using the technique of a low-mass lateral impactor multiplicated with peach. Using the theory of elasticity, the independent variables were determined as Fmax (maximum impact force), contact time (tmax), Fmax/tmax, 1/tmax, 1/tmax2,5, Fmax/tmax 1.25 and Fmax2.5 parameters. The correlation coefficient values showing the relationship between these parameters and the dependent variable Magness-Taylor force (MT) were calculated and were combined with meta-analysis by using the Hunter-Schmid and Fisher’s Z methods. The Cohen’s classification criterion was used in evaluating the resulting mean effect size (combined correlation value) and in determining its direction. As a result of the meta-analysis, the mean effect size according to Hunter-Schmid method was found 0.436 (0.371-0.497) positively directed in 95% confidence interval, while it was found 0.468 (0.390-0.545) according to Fisher’s Z method. The effect sizes in both methods were determined “mid-level” according to the Cohen’s classification. When the significance level of the studies was analyzed with the Z test, all of the ones that taken into the meta analysis has been found statistically significant. As a result of the meta analysis in this study evaluating the relationship of peach types with the fruit hardness, the mean effect size has been found to reach “strong level”. Consequently, “maximum shock acceleration” was found to be a more effective factor comparing to the other factors in determining the the fruit hardness according to the results of meta analysis applied in both methods.

2014
Murat Türkeş
This paper focuses mainly on both impacts of the climate change on agriculture and food security, and multidisciplinary scientific assessment and recommendations for sustainable agro ecological solutions including traditional knowledge responding to these impacts. The climate change will very likely affect four key dimensions of the food security including availability, accessibility, utilization and sustainability of the food, due to close linkage between food and water security and climate change. In one of the most comprehensive model studies simulating impacts of global climate change on agriculture to date, it was estimated that by 2080, in a business-as-usual scenario, climate change will reduce the potential output of global agriculture by more than 3.2 per cent. Furthermore, developing countries will suffer the most with a potential 9.1 per cent decline in agricultural output, for example with a considerable decrease of 16.6 per cent in Africa. Some comprehensive studies pointed out also that all regions may experience significant decreases in crop yields as well as significant increases, depending on emission scenarios and the assumptions on effectiveness of carbon dioxide (CO2) fertilization. One of the tools that would ensure the food security by making use of local sources and traditional knowledge is agroecology. Agroecology would contribute to mitigation of the anthropogenic climate change and cooling down the Earth’s increasing surface and lower atmospheric air temperatures, because it is mainly labour-intensive and requires little uses of fossil fuels, energy and artificial fertilisers. It is also necessary to understand the ecological mechanisms underlying sustainability of traditional farming systems, and to translate them into ecological principles that make locally available and appropriate approaches and techniques applicable to a large number of farmers.

The aim of the present research was to determine the relationship between somatic cell count (SCC) and milk composition. Milk samples were collected in November and May in 2012. In the study, 128 milk samples from Brown Swiss cattle, divided into two groups. They were arranged from low score (≤500 000cell/ml) to high score (>500 000cell/ml) according to the Turkish Food Codex upper limit. The averages of SCC were determined as 10.444±0.073cells/ml for first group and 10.820±0.088cells/ml for second group, respectively. In the one group dry matter, non fat dry matter, fat, protein, lactose levels and standard errors were determined as 13.3±0.60%, 8.3±0.21%, 4.5±0.61%, 3.0±0.14% and 4.7±0.07%, respectively. The other group same traits were calculated 13.7±0.17%, 7.9±0.10%, 5.8±0.14%, 3.0±0.06% and 4.1±0.05%, respectively. Significant correlations were found between SCC and non fat dry matter (r=-0.109) protein (r=0.145), lactose (r=-0.490) in the second group. But, non significant correlations were determined between SCC and dry matter, non fat dry matter, fat, protein and lactose in the first group. As a result, increasing of the number of somatic cells, milk, lactose, protein, and fat-free dry matter content was determined to be significantly affected.

Bora Şen | Sevilay Topçu | Özkan Güğercin | Hasan Hüseyin Öztürk
Greenhouse construction projects need to consider local climate characteristics, production type in the greenhouse and materials used for the physical structure and glazing. A major share of commercial greenhouse manufacturers in Turkey produce turnkey greenhouse projects either using by trial and error method or imitating/reproducing greenhouse imported from other countries. Improperly designed projects may result in greenhouses having weak construction or more expensive structures due to using unnecessarily larger profiles which consequently cause a loss the profits for the growers. This study aims to contribute to the improvements and overcome the gaps in practice of greenhouse projects by designing a software for an expert system that utilizes an accurate Project considering them and mandatory buildings standards of Turkish Standardization Institute (TSE). The expert system, named SERASİM, has been developed within the framework of the present MSc. Thesis and enables calculating each part of the construction system of a gable roof glass house according to TSE standards. Besides calculations for statics, dynamics and strength as well estimating the bill of quantity, SERASİM can be utilized to determine the heating requirements and costs for selected locations and crops. SERASİM may also be used as a teaching tool for courses including greenhouse design, protected cultivation and greenhouse acclimatization.

In this study, it was aimed to demonstrate the effect of humic acid applications on some morphological, physiological and biochemical characteristics of eggplant genotypes (Burdur Merkez, Burdur Bucak, Kemer and Giresun) irrigated with the irrigation water with a high content of heavy metal and determined previously salt tolerance levels. In studies conducted in controlled greenhouse conditions, eggplant seeds germinated in the growth substrate a mixture of peat and perlite and the seedlings were transplanted into pots at 20 days after sowing. Plants when they are 4-5 true leaves, 3 different humic acid levels (0, 500, 1000 ppm) have been applied and 7 days later after this application began to be watered with 3 different irrigation water comprising a mixture of various doses of heavy metals (control: 0 ppm; I. Mixture: 0.2 ppm 5 ppm to 0.01 ppm Cd + Cu + Pb + 2 ppm Zn, II. mixture: +0.02 ppm 0.4 ppm Cu 10 ppm Pb + Cd + 4 ppm Zn). Field capacity level for the plants 40 days after quenched with water after which time they were harvested and samples for analysis were performed. In the study plants were investigated for shoot and root fresh weight, shoot and root dry weight, shoot and root length, leaf area, chlorophyll and MDA level of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR) enzyme activities All genotypes are adversely affected by heavy metal applications. In parallel to increase the dose, heavy metal mixtures led to a reduction in values of fresh and dry weight of shoot and root, stem and root length, leaf area of eggplant genotypes. MDA and antioxidative enzyme activities increased in plants irrigated with water containing a mixture of heavy metal. Humic acid applications had a positive effect on reducing of the limiting effect of heavy metal stress on growth and development. As a result, compared to sensitive genotypes Giresun and Kemer, salt tolerant genotypes Burdur Merkez and Burdur Bucak showed much better resistance to abiotic stress factor which consists of heavy metal applications. The obtained results; formed also an opinion about that plants evolved similar strategies for resistance to abiotic stresses such as salinity, drought and heavy metal stress.
