Today, the effects of climate change in the world are manifest in all its reality. These changes were being affected Turkey as well as the world, regions and provinces leads to a difference in some. In this study, projections of 10, 15 and 20 and 50 years of future maximum averages have been made according to the provinces in some regions by using the maximum average datas of the past 50 years of Ankara, Kars, Aydın and Sinop provinces selected especially from different regions to evaluate the climatic changes. According to the results of the analysis, the total average temperature data between 1966-2015 was 17.90°C in Ankara, Kars 11.69°C, Aydın 24.50°C and Sinop average temperature was 17.28°C When compared in 2016-2065 projections, it is seen that there will be changes in average temperatures in parallel with climate change. In Northeastern Anatolia, the highest temperature increase is foreseen with 3.45°C, followed by Sinop, a Black Sea province, with 1.99°C. Ankara, which has a continental climate of Central Anatolia, is estimated to be 1.77°C and it is thought that the Aegean province Aydın will be exposed to a temperature increase of 1.55°C at the lowest rate. Other forecasts are predicted to have the highest temperature changes in Kars and Aydın’s minimum temperature changes. The detection of temperature changes in the study is considered to be important in terms of planning agricultural activities accordingly as well as regulating urbanization and water use and taking measures.

In this study, fertility and milk yield characteristics of Simmental (SIM) and Red-Holstein (RH) cattle raised in a private dairy farm in Aydın province were determined. For fertility traits, days open (DO), calving interval (CI), gestation length (GL) and number of inseminations per pregnancy (NIPP), for milk yield traits lactation length (LL), lactation milk yield (LMY), 305-days milk yield (305-dMY), peak time (PT) and peak milk yield (PMY) were determined. The means of DO, CI, GL and NIPP of RH and SIM breeds were 109.44±5.66 d and 96.06±3.51 d, 389.16±5.70 d and 380.37±3.54 d, 279.71±0.469 d and 284.94±0.303 d, 1.88±0.099 and 1.85±0.065; the means of LL, LMY, 305-dMY, PT and PMY were 333.00±5.405 d and 322.72±3.233 d, 8235.32±148.099 kg and 7357.03±88.122 kg, 7628.78±109.148 kg and 6938.09±64.945 kg, 46.55±2.196 d and 44.46±1.218 d, and 34.68±0.567 kg and 31.47±0.314 kg, respectively. Although, significant fertility and milk yield differences were obtained between the breeds, the favorable performances of both SIM and RH breeds in terms of all features, considered as the environmental factors such as management-feeding-housing-herd management provided to animals in the farm were also suitable.

The aim of this study was to determine the reproductive characteristics, milk yield and milk quality of Primiparous Red-Holstein (RH) and Holstein-Friesian (HF) cows. For this aim, records and monthly taken milk samples of 83 RH and 14 HF raised on a farm in Aydın, Turkey were used. The averages of the first calving age (FCA), gestation length (GL), days open (DO), calving interval (CI), daily milk yield (DMY), 305-day milk yield (305-dMY), solid non-fat (SNF) and Log10 somatic cell count (Log10SCC) of milk were found to be 27.6±0.24 mo, 278.4±1.09 d, 144.0±7.12 d, 421.4±7.66 d, 22.7±0.21 kg, 6981±137.0 kg, 9.8±0.04% and 4.59±0.024 (38905 cells/ml), respectively. Except for DMY, the differences between the breeds were statistically insignificant for FCA, GL, DO, CI, 305-dMY, SNF and Log10SCC. DMY averages for RH and HF were 21.8±0.21 kg and 24.3±0.49 kg, respectively. The effect of season on FCA and the effect of lactation month on SNF and Log10SCC were also found to be statistically significant. Apart from DMY, not any significant difference was observed between RH and HF breeds in terms of the characteristics emphasized.

Objective of this study is to determine plant protection problems which wheat growers encountered and their knowledge on plant protection in Sivas province. This study is carried out in the Central, Hafik, Ulas and Yıldızeli districts of Sivas province with 220 farmers. The problems which related to plant diseases, pests and weeds in wheat growers faced were also determined. Almost all farmers (99.09%) apply chemical control. Farmers decides the pesticide applications in their wheat growing areas according to own experience (84.09%), manufacturers recommendations (24.09%), the advice of agricultural experts (17.27%) and the advice of neighbours and friends (9.55%). Farmers mostly have been applying pesticides based on their own experiences. In recent years, pesticides are being used widely against diseases, pests and weeds. Some times over dose application of pesticides by farmers in judiciously resulted in environmental pollution, health problems. Also the natural enemies will be affected. Furthermore, in weed control farmers use herbicides against broad leaved weeds. It was determined that the farmers do not have knowledge about narrow leaved weeds and herbicides use against these weed species is limited. According to the results of this survey, it will be beneficial to provide training on plant protection to wheat producers in the region.

Nitrogen losses in agricultural areas cause environmental pollution. At the same time, it reduces the yield in crop production. The aim of this study is to investigate the effects of zeolite and nitrogen applications on the development of maize plant. Another aim is to reveal nitrate changes in soil. Everest maize variety was used in the study. Zeolite doses of 0, 125, 250 and 500 kg/da were applied to the soil. Nitrogen doses were applied to the soil at 5, 10, 15 and 20 kg/da. In this study, zeolite and nitrogen applications increased the plant height, cob weight and green forage yield of maize plant statistically. The highest green weed yield was 6563 kg/da in Z3N3 application and the lowest green forage yield was 4021 kg/da in Z0N0 application. Increased nitrogen doses increased the amount of nitrate in soil by significantly 1% and zeolite applications increased by significantly 5%. The results of this study would be beneficial in the application of zeolite to the soil in order to reduce nitrogen losses and to make the plant benefit more from nitrogen.

Kaz yetiştiriciliğinde verimli ve karlı bir üretimin yapılabilmesi ancak sağlıklı sürülerin olması ile mümkündür. Her ne kadar kanatlı hayvanlar içerisinde hastalıklardan en az etkilenen tür kazlar olmasına rağmen, kazlarda ciddi kayıplara neden olan birçok bakteriyel, viral, paraziter ve mantar hastalıkları bulunmaktadır. Diğer kanatlılarda olduğu gibi kaz yetiştiriciliğinde de hastalığın tedavisi, korunmadan daha pahalıdır. Bu nedenle hastalıkların çıkmasını ve yayılmasını en aza indirmek, hastalıkların tedavisinde tasarruf sağlamak, sürü sağlığını iyileştirip-geliştirmek, hayvan ölümlerini en aza indirmek ve işletme karlılığını artırmak için biyogüvenlik prosedürlerinin uygulanması gerekmektedir. Bu biyogüvenlik prosedürleri ise rutin ve yüksek riskli olmak üzere iki şekilde yapılabilir. Rutin biyogüvenlik prosedürleri hastalık etkenlerinin işletmeye girişinin engel olunması, etkili hijyen ve sanitasyon programının uygulanması, yeterli bağışıklığın oluşturulması için etkili aşı programlarının olması, kalifiye personel ile çalışılması, sürü yönetim programının düzgün olması ile denetim ve kontrolün iyi bir şekilde yapılması ile mümkündür. Yüksek riskli biyogüvenlik prosedürleri ise şüpheli ve salgın bir hayvan hastalığı durumunda planlı ve programlı bir şekilde yapılması gereken uygulamalardır. Sonuç olarak kaz yetiştiriciliğinde biyogüvenlik prosedürleri etkili ve disiplinli bir şekilde yerine getirilirse, sağlıklı sürüler ve daha fazla kârlılık elde edileceği unutulmamalıdır.

The present study was focused on the design and implementation of an experimental recognition system for dirty chicken eggshell by using an image analysis technique. Image analysis based observation and evaluation techniques can be used efficiently and effectively for agricultural product quality control. Dirt stains on eggs are the result of mainly by feces (black to light brown stains), uric acid (white stains), yolk, and blood. The experimental system was used to obtain dark level images of dirty stains of chicken eggs owing to feces. For this aim, the dirty chicken eggs which have dirty parts were put under a webcam, and dirtiness degree was evaluated by using developed image analysis software at the LabVIEW platform. For the experiment, 100 clean and 100 dirty eggs were used to accurate the determination of dark stains. The results of the research showed that the designed experimental system pointed an accuracy of 99.8% at painted grade eggs. On the other hand, the accuracy of the differentiation of the dirt stains by feces was 98.5%. The developed system can be upgraded for developing egg sorting machines by presence-absence of dirty stains in eggshell.

In this research, the effect of extract obtained from waste mandarin peels on inhibition or retardation of ageing of the leather was investigated. Firstly, mandarin peels were extracted and antioxidant activity of the mandarin peels were detected by using of DPPH method. This antioxidant method is based on DPPH that is a purple stable compound, inhibition with sample compound. Extracted mandarin peel samples were read by spectrophotometer at 517 nm wavelength. At final, antioxidant activity of mandarin extract was determined as 65 µM TE/g. The mandarin extract treated with leather after formic acid fixation as a fixator. Goat leathers were kept under 80°C/UV for 72 hours for aging process and the colour values of initial and hindermost leathers were measured with using of Konica Minolta CM 3600d Brand spectrophotometer. L*, a*, b* and ΔE values of the samples were calculated. At the end of the study, it was found that mandarin extract was a natural antioxidant and if it was used as a fixator it could have aging retardant effect at the leather production. Also, it was determined that the use of waste mandarin peels extract increases the brightness of the leather. The difference between the colour values of the leather samples in which the extract was used and not used was found statistically significant.

The effects of environmental factors and reproductive activities on proximate composition of freshwater mussels, Unio pictorum, was investigated from February 2013 to February 2014 in Sinop, Turkey.
