Microbial population of soil and its structure is affected with chemical and biological changes such as plant-root secretions. Upper layer of the soil is exposed to mixture of stems, fruiting bodies and leaves of trees. Seven trees growing at same area were chosen. Their upper layers of the soil were collected from depth 5-10 cm as samples in spring and autumn. Their microbial populations were investigated in order to determine in terms of climate changes. In order to determine the number of the total microorganisms, gram-negative bacteria and spore-forming bacteria (cfu/g) were used by the serial dilution techniques. As a result, the highest numbers of microorganisms from the soil of the apple tree were determined as the total microbial count in the autumn, although the lowest number of microorganisms was obtained from the soil of the pine tree. However, the number of the gram-negative bacteria was the highest in the soil of linden tree, although the number of gram negative bacteria was the lowest in the soil of apricot, mulberry and apple trees. For spore - forming bacterium, the highest number from the mulberry soil and the lowest number from the linden tree have been obtained. In the spring, the highest numbers of microorganisms from the soil of the apple tree were obtained as the total microbial count, although the lowest number of microorganisms was obtained from the soil of the apricot tree. For the number of the gram-negative bacteria was the highest in the soil of walnut tree, although the number of gram negative bacteria was the lowest in the soil of apricot trees. However spore - forming bacterium, the highest number from the soil of the poplar tree and the lowest number from the mulberry tree have been obtained. In general, the rich diversity of the microbial population was shown morphologically in autumn.

In order to determine the effects of nutrient (P, Si, NH4, NO3) enrichment on the growth of phytoplankton in Homa Lagoon (İzmir Bay, Aegean Sea), experiments of enrichment with discontinuous cultures have been executed seasonally in 2007. In our study, the elements limiting the growth of phytoplankton were NO3, P and Si in spring season, N and P in summer season, and NH4 in autumn and winter seasons. So, it has been determined that the addition of nitrogen (N) and phosphor (P) has led significant change in biomass and growth of phytoplankton. It has also been observed that diatom and dinoflagellate species have grown under various concentrations of, especially, Silicate (Si) and nitrogen (N).

In this study, it was aimed to determine reproduction biology of Capoeta trutta (Heckel, 1843) obtained from Ağın and Örencik region of Keban Dam Lake. For this purpose, fish samples were monthly collected during a year and their sexes were determined. The maturation age for female Capoeta trutta caught from Ağın region was determined as 2 while it was 3 for females from Örencik regions. Maturation age was found to be 2 for male C. trutta for all regions. The Gonadosomatic Index Value (GSI) reached to the highest in May for both sexes and reproduction period for the fish was estimated between May and June.

In this review, the share in total and the presence of cattle in provinces of GAPUTAEM has been referred. According to official data of 2012 of TUIK, when number of cattle was 11.972.923 heads in 1991, in 2012 years increased 13.914.912 heads. According to year of 1991, number of cattle increased 16%. In our country, the number of Anatolian Water Buffalo declined from 366.150 heads to 107.435 heads during 1991-2012 and this reduction is 70.6%. 15.977.838 tons milk was obtained from dairy cattle of 5.431.400 heads and average milk yield was 2.942 kg/head. 46.989 tons milk was produced from 46.959 heads of Anatolian Water Buffaloes and average milk yield was 1.006 kg/head. However, there were totally cattle of 1.173.008 heads in study field of Institute. 1.098.895 tons milk was produced from cattle of 451.039 heads. Totally, there were 15.478 heads Anatolian Water Buffaloes in 11 provinces. 6.384 tons milk was produced from 6.738 heads Anatolian Water Buffaloes in 2012. Across the country, despite cattle (domestic) decreased, cattle (cross-bred) and cattle (culture) had increased. The possibility of breeding of native cattle should be investigated. Also, growers and technical staffs should be trained that affected by entering of culture breeds.

The objective of this study was to test the effects of dietary natural zeolite (clinoptilolite) on performance, skin and liver histology in rats. In this study, 24 10-week-old, weaned, adult male Spraque-Dawley rats with approximately 306 +- 18.93 g initial live weight were used. The rats were randomly divided into four groups with three replicates, including a control group and groups with one of three doses of clinoptilolite (2%, 4%, and 6%) in their diets. All the rats were fed these concentrates throughout the experimental period of 56 days. The animals were reared individually in stainless steel cages. There were no significant differences in the primary and secondary follicle numbers among groups, but the diameters of each follicle were found to be significant. The primary and secondary follicle numbers and diameters ranged from lowest to highest as follows: 2.00-2.33, 4.50-7.17; and 11.53-20.42, 57.63-102.12um, respectively. The differences occurred between the control group and group IV (containing 6% zeolite). In addition, the skin and liver histology results showed that there were no differences among the groups.

Pulse processing industry almost all located in Mersin province in Turkey. Strategic importance considered both national and international trade in terms of capital, domestic and foreign trade connections, knowledge and experience, pulse processing technology Mersin has an important position in the world. However, decline in pulse crops production in recet years, market fluctuations lead companies to import intensively and competitor countries have become major supplier. In the study, these developments in pulse production and trade in recent years, companies and also researchers opinions take into account to determine companies strengths, weaknesses, opportunities, and threats for SWOT analysis with the aim of offer sector-oriented strategies. Results of SWOT analysis were analyzed with SOR analysis. It is tried to develop strategies for development of pulse industry.

Root-knot nematodes (Meloidogyne spp.) have specialized and complex relationships with their host plants. A better understanding of interaction between nematode and their host will help to provide new point of view for root-knot nematode management. For this purpose, recently investigations on cellular and molecular basis of root-knot nematode parasitism and host response were reviewed.

An experiment was conducted to determine the effect of different combination calcium sources and particle size on performance and egg shell quality in layer hens. In the experiment, 198 brown laying hens at 44 week of age were randomly assigned into 11 treatments groups. The experimental diets consisted of different calcium sources (Fine limestone, large limestone, large oyster shell and large egg shell) and their different combination. The experimental unit consisted of a groups of three hens, thus each treatment was replicated six times. Different calcium sources and particle size addition to the laying hens diet had no significantly effect on body weight gain, egg production, egg mass, feed intake, feed conversion ratio, egg specific gravity, egg shell weight, egg shell thickness and egg shell breaking strength but egg weight had significantly affected by the treatments. The significantly highest egg weight was found in laying hens fed with 50 % fine limestone and 50 % large limestone. Dietary different Ca sources had a significant effect on Ca, P and Mg as mineral contents of eggshell and tibia. In the present study, when dietary large calcium sources (limestone, oyster shell and egg shell) had no effect on performance and eggshell quality parameters in laying hens. However, dietary containing at least 50 % large calcium sources had positive effect on mineral contents of tibia.

The aim of this study was to evaluate the effect of choice feeding based on threonine on performance characteristics and carcass parameters of male broiler chicks. Day old, thirty Ross 308 male chicks were divided into two dietary treatment groups. In the experiment, choice feding did not affect on body weight gain, feed conversion ratio. Feed intake and carcass parameters significantly affected by experimental treatments.

In this study, total phenolic content and antioxidant capacity of various dried fruits were investigated. Total phenolic content of dried fruits (apple, quince, peach, orange, grapefruit, kiwi, banana, watermelon, cantaloupe, strawberries and tomatoes) were between 219-5386 mg GAE/kg in dry matter (dm). TEAC and ORAC values of the samples were between 7.01-126 µmol TE/g dm and 11.69-211 µmol TE/g dm, respectively. Dried fruits can be considered as an important source of antioxidant components in diet with the higher antioxidant properties.
