2020
Esra Tuğçe Şentürk | Alpönder Yıldız
This study has been carried out to investigate that the effect of different levels of in ovo zinc, manganese and copper mineral mix injection on the hatchability and some tissue characteristics in the Japanese quail breeder eggs. In the study a total 400 Japanese quail breeder eggs which have similar weight have been randomly distributed to four different experimental groups: C as control non-injected (C), MinMix1 has been injected with 15+15+3 µg Zn-Mn-Cu mineral mix + 0.2 ml physiological serum per egg, MinMix2 has been injected with 30+30+6 µg Zn-Mn-Cu mineral mix + 0.2 ml physiological serum per egg and MinMix3 has been injected with 45+45+9 µg Zn-Mn-Cu mineral mix + 0.2 ml physiological serum per egg. The effect of treatment on hatchability, hatching weight and tibia weight, leg, beak and tibia lengths has been found to be unimportant. The yolk sac weight was lower in the injected groups compared to the control group, whereas the heart and liver weights, chick and wing lengths have significantly increased with the in ovo mineral mix injection. The hatching of chicks in the injected groups has started earlier than the control group and the hatchings of these groups were completed earlier, except for the MinMix3 group. These results demonstrated that in ovo injection with MinMix2 increased heart and liver weights and chick and wing lengths while in ovo mineral injection decreased yolk sac.

This study was carried out with 86 Bituminaria bituminosa (Bitbit) genotypes collected from Central Black Sea Region of Northern Anatolia in Samsun in 2012. After cleaning, seeds scarifying with sandpaper and sown in small pots. In November of 2012, the seedlings were transplanted to experimental field. No fertilizer and water applied throughout the study and spring and autumn elongation, hay yield and harvesting number in the second year of the plants (2014) were observed during the study. According to correlation analysis, there was a negative and statistically significant linear correlation between altitude and spring elongation, autumn elongation, harvest number. There was also a negative statistically insignificant correlation between altitude and hay yield. A positive and significant correlation was found between hay yield and spring and autumn elongations, harvest number; between spring and autumn elongations and number of harvest. Some genotypes taken from high altitudes stayed dormant in winter period, furthermore they started elongation later than the others and a slight growth was recorded in autumn. In the light of these results, it is possible to improve cultivars for different ecological conditions.

2020
Adil Koray Yıldız | Hakan Keles | Servet Aras
Some vegetative properties measured in fruit trees are important indicators in examining of plant growth calculation, estimation of leaf area index in evapotranspiration, fertilizer requirement etc. These measurements reflect the effects of the cultivation treatments in many areas of commercial growing and scientific studies. One of the most important measurements is the status of the canopy development. Canopy width, area and volume can be measured with some calculations. However, more technological equipment may be needed to reduce work and labor, and to make the results more precise and clearer. Recently, unmanned aerial vehicles, which have become widespread, have a wide potential for use in agriculture. By using image processing methods, it is possible to make more objective and high accuracy evaluations much faster. In this study, the images of the apple trees (Malus domestica Borkh) cultivar Golden grafted onto MM106 rootstock, were taken by light unmanned aerial vehicle to calculate the canopy area and then these images were analyzed using image processing methods for calculating canopy areas. Both circular and elliptical calculation methods were used. The area calculations with image processing methods were compared with the areas obtained manually. Comparisons were made by regression analysis. For the most successful method R value was 0.9662 for elliptic area and 0.9346 for circular area which was calculated by image processing. The results demonstrated that the image processing can be an alternative method to determine the canopy area according to accuracy ratios.

Ayşe Esra Peker
That agricultural sector is examined closer from every point of view and is restructured in complied with the requirements of the age has to be structured comes to our face as a reality any longer accepted by every sector of the society. The various developments experienced in the world in the recent years have directly or indirectly affected agricultural sector. In the economy of Turkey, one of the countries attracting attention with its rapidly growing, there are many theoretical studies dealing with the direct or indirect contribution of agricultural sector. However, it is necessary to increase the number of the applied studies introducing the existing situation of the sector and enabling to develop the effective policies for the sector. For, it is highly important for the theories put forward in theoretical framework to be supported by empirical analyses in terms of forming effective policy suggestions. In the study, the three sub-sectors were considered such as the subsectors of cereal, legume, and fruit-vegetable and the existing situation of the sector was analyzed by moving from the macro variables. In order to identify the effects of macroeconomic variables (inflation, exchange rate, interest, monetary supply), selected in the direction of the aim of the study, panel cointegration test was utilized. Setting off from this point, when the analysis made in the study is examined for all sectors, it was identified that the variable affecting the sector the most was interest rate. When the results of panel cointegration test between interest rate and agricultural production were examined, while there was a negative directional relationship between the production of subsector “fruit vegetable” and the variable “interest” as expected, it attracts attention that there was a positive relationship between the subsector of cereal legume and interest in contrast to this.

2020
Aydın Alp | Özlem Toncer | Sadettin Çelik
Tobaccos produced in Turkey are grouped under different names according to the different environmental properties and various characteristics of the regions where they were grown. Lice tobacco is an important local tobacco variety cultivated under Lice-Hazro and Kulp districts conditions. In recent years, a large number of tobacco origin and village populations disappeared from production and faced the danger of extinction. Especially the Lice local tobacco variety has gained a very good adaptation ability against the stress factors of the region. Different environmental factors such as high altitude, stony areas and high temperature, low rainfall and low nitrogen soils have determined the important quality characteristics that distinguish Lice tobacco from other tobacco types. The short plant height and reverse conical plant shape in Lice Tobacco produced in Lice District and around of Diyarbakır draws attention firstly. In Lice tobacco, the number of leaves per plant is 15-17 pieces / plant, the ratio of the length of the leaves to the width (38 cm / 23 cm), the elliptical leaf blade, dark green leaves and plant color, early flowering, the petal color is pinkish red. It is a local variety with high cigarette yield, low nicotine ratio (1-2%), protein nitrogen ratio 1%, total reducing substance ratio 15%, and the highest alkaloid ratio. In this study, the plant and quality characteristics of the local Lice tobacco variety, which has a high degree of genetic diversity, were investigated in farmer conditions and the differences with other Eastern and Southeastern Anatolian tobacco varieties were tried to be revealed.
