2016
Ethem Akyol
This study was conducted to determine the better hygienic behaviour determination method that is used in controlling against bee diseases and pests. Total forty honeybee colonies (Apis mellifera anatoliaca) were used and they were randomly divided into two groups (each group consists of twenty colonies) in first year. Liquid nitrogen method was used in the first group' colonies and pin-killing (needling process) method was used in the second group’ colonies to determine the effectiveness of methods for hygienic behaviour. Average clearance rate was found as 66.25% and 78.10% in the first (Liquid nitrogen application) and the second (pin-killing) groups respectively. In the second year, forty colonies were divided into five equal groups and each group consisted eight colonies. The first group consisted of 9 frames bees in standard langstroot hive (10 frame capacity), the second group consisted of 5 frames bees in standard langstroot hive (10 frame capacity), the third group consisted of 5 frames bees in ruşet hive (5 frame capacity), the forth group’s consisted of 3 frames bees in ruşet hive (5 frame capacity) and the fifty group consisted of queen mating hive. The pin-killing (needling process) method, tested in first year, was used for all groups to determine the effectiveness of colony population and the size of hive. Average clearance rates of the first, second, third, forth and fifth groups were 70.54%, 58.38%, 70.63%, 54.96% and 58.21% respectively. The colonies that belonged to the pin-killing (needling) group showed a higher cleaning behaviour rate than the other colonies. The density of bees in hive had an important effect on the clearance rate of colonies. The colonies of group 1 and group 3, which had the more density of bees in per unit area, had the higher clearance rate than the other groups.

Şerife Gülden Yılmaz | Mevlüt Gül
This study was aimed to examine the cotton production techniques and determined of input use in the cotton production. The primary data used in research was obtained from 94 cotton-growing farms by surveying method in the Antalya province. The data belonged to 2011 production period. In the research area 95.74% of agricultural farms made conventional farming. It was determined that cotton seed was used 2.43 kg per decares and 27.7% of farmers had soil analysis and 24.5% of them applied fertilizer according to the analyses. It was determined that the average fertilizer applications per decares were 24.9 kg nitrogen, 17.2 kg phosphorus, 8.2 kg potassium and 0.5 kg sulfur fertilizer. It was calculated that the average number of plant spraying 5.4, the number of irrigation 4.53 in the cotton cultivation. The application level of water-saving irrigation techniques of farmers was low(2.12% of farmers used drip and sprinkler irrigation system). Labor force was used as 53.95 hours and machine was calculated as 3.06 hours per decares. Mechanization of the cotton harvest increased. It was determined that 47.87% of farmers did not receive consultancy services; 22.34% of farmers were knowledgeable about the concept of integrated pest management and 41.5% of farmers were knowledgeable about good agricultural practices in the region. In order to increase the production of cotton in the region; new varieties which will be compatible to the region, higher levels of yield, resistant to disease and pests should be developed and farmers should be informed about technical applications by extension personnel.

Aslı Zungur Bastıoğlu | Safiye Nur Dirim | Figen Kaymak Ertekin
Yogurt powder was produced by freeze drying and with added candied chestnut puree at ratios of 5, 10, and 20 % by weight. Moisture sorption isotherms of yogurt powder samples, plain (YP), and containing 5, 10, 20% candied chestnut puree (CCP) were determined at 25°C using the standard, static-gravimetric method. The experimental adsorption data of yogurt powders at 25°C were fitted to 14 sorption equations which are most widely used to fit experimental sorption data of various food materials. The parameters of the sorption models were estimated from the experimental results by using the nonlinear regression analysis. The GAB model gave the closet fit to the sorption data of freeze dried yogurt powders with candied chestnut puree at 25°C. BET, Ferro Fanton, Henderson, Halsey, Oswin and Modified Oswin models are also acceptable for describing the adsorption isotherms for freeze dried yogurt with candied chestnut puree at 25°C.

2016
Gülsüm Yaldiz | Muhammad Sameeullah | Mahmut Çamlıca | Faheem Shehzad Baloch
Genetic variation is prerequisite for plant breeding. Nothing information existed in the literature for available diversity of Coriander accession in Turkey. Plant breeding activities are negligible in Turkey. So in order to start effective plant breeding program in Turkey, information on the available genetic diversity is viable. Therefore we planned to study the genetic variation and population structure of 29 Coriander accessions by seed storage protein (SDS). SDS analysis elaborated the lack of population structure and genetic bottleneck in the Coriander accessions in Turkey. Based on the results of this study, it was clear that sampling strategy was not appropriate and plant introduction should be made from different sources and diverse genotypes should be used as parents to initialize the effective Turkish Coriander breeding program.

Pratishtha Adhikari | Gopal Bahadur Khatri-Chhetri | Sundar Man Shrestha | Santosh Marahatta
Forty seed sample of wheat (Triticum aestivum) were collected from four locations viz. Chitwan, Kaski, Banke and Lalitpur and tested by blotter method at laboratory during 2013 for determining fungal pathogens associated with wheat seeds in Nepal. Eighteen species representing thirteen genera of fungi were recovered from the seed. Alternaria alternata and Bipolaris sorokiniana were predominant in all the varieties/genotypes from all the locations, where B. sorokiniana was strongly pathogenic in wheat crop. Percentage frequency and type of fungi detected varied with variety and locations. Bipolaris sorokiniana was highest (64.40%) in Banke than remaining three locations. Seeds of Chitwan had lowest percentage (5.50%) of seed infection as compared to other locations. Relative abundance of Alternaria alternata (55.10%) was highest as it was the most prevalent component of seed borne mycoflora, followed by Bipolaris sorokiniana (34.69%) and Cladosporium herbarum (7.19%). Differences in quantity of precipitation and relative humidity might be the possible reason for variation in frequency and type of fungi detected in wheat seeds of four locations.

The aim of this study is to evaluate the quality characteristics of physical, chemical and microbiological of some fruit nectar samples produced from some local and imported companies and sold in the city of Tripoli, and to determine their conformity with Libyan specification standards. In this study, 40 samples of different fruit nectars (grape, pineapple, guava, orange, apple, and mixed fruits) were collected from different local supermarket, five imported companies and 4 domestic which were available at the time of study. The Samples were classified based on their type of fruit nectars and also marked as (A, B, C, D) and (E, F, L, M, N) for different domestic or imported and imported companies respectively. The results showed that all the samples were free from artificial colours added. Local and imported samples were conform with the Libyan specification standards (990-2014) for fruit nectars. Five local and four imported samples were unconfirmed with the standards. In terms of acidity, some local and imported samples were conform to the Libyan specification standards, except one local sample and 5 imported samples. However, 35.3% of local samples and 43.5% of the imported samples unconfirmed to the Libyan standard specifications. Microbiological results showed that all local and imported samples were free from total bacterial count, yeasts and molds and coliform bacteria. Heavy metals (cadmium, lead, arsenic, copper, zinc, iron) of local and imported samples were conform to the Libyan specification standard, except 3 samples of imported products were had higher arsenic concentration. Based on the results of this study which indicated the importance of quality control programs for such products not only during production but also during storage and sales due to possibility of contamination and spoilage.

The purpose of the study is to compare Agricultural Knowledge and Information Systems (AKIS) for adopters and non-adopters of Good Agricultural Practices (GAPs) in the Bafra district of Samsun, Turkey. The main materials of this study are the data obtained from a survey and interview with adopters and non-adopters of GAPs in Bafra district. The research data were collected from 77 farmers contained both adopters and non-adopters of GAPs. Statistical analysis, such as Chi-square and t-test was used. The study results presented the socio-economic characteristics of farmers. There was a significant difference between adopters and non-adopters of GAPs, according to household size, organizational membership, farm size, livestock and crop production. Meanwhile, the information sources such as a district agricultural manager/personnel, adviser of the farmers’ union association (GAPs) and pesticide/fertilizer dealers were preferred the main sources of agricultural information for adopters of GAPs. However, it recommended that information sources like research institute, university and cooperatives needs to be improved by strengthening their way of information dissemination. In terms of usefulness of AKIS for this study, it seems that this system was insufficient to analyze this study. Even though the functions of this system are essent ial elements, they are insufficient for establishing a network of complex innovation-oriented institutional arrangements. In the future, this study suggests to analyze GAPs it needs to use Agricultural Knowledge and Innovation System (AKIS) approach, because this system have many interaction networks that can facilitate the researchers to reach the innovation easily to the intended farmers.
